Film vs. Foam – Choosing the Correct PSA for Automotive Applications.

When working with automotive pressure-sensitive adhesives (PSAs) — or most any purchase in the supply chain, for that matter — three factors weigh heavily on the buying decision:

  • Material
  • Price
  • Quantity

Finding the right materials, at the right price point, with a reliable unit volume is a straightforward goal, but it often takes some time. Suppliers can have dizzying catalogs of films and tapes to sift through with nuanced differentiators that make it tough to compare specs tit-for-tat. You may go into the search with a clear idea of the automotive design problem you need to solve but less certainty about the ideal polymer or adhesive formula. A lower price point might not provide much value if the material is poorly matched to the task. 

Modern automotive PSAs are versatile, too. Every area of the vehicle will have some specialized options: matte black vinyl paint replacement tapes window sashes and door pillars, for instance. However, as synthetic adhesives have evolved, their material advantages have begun to expand and overlap across multiple use cases and purposes.

Film vs. Foam PSAs

Synthetic films and foams are two of the most common carriers (or cores, or backings) for automotive PSAs. Each style has unique properties that will suit it to certain tasks or substrates, and both have the ability to accommodate single or double-sided adhesion. Acrylic, silicone, rubber, or other adhesive layers will also affect the strengths and value of the PSAs.

Neither film nor foam is specifically “better.” The perfect selection comes down to a harmonious match of carrier, adhesive, substrate, purpose, and anticipated environmental stresses. To settle on the correct PSA for your project, we must start with an examination of the qualities and resistances of each polymer.

Foam Options

Whereas films are best used to shield surfaces from scratches, rough frictional contact, and corrosive liquids, foams are better at filling gaps, dampening vibrations, and creating flexible bonds, even on irregular, textured, or rough surfaces. In protective roles, foam will not withstand abrasive forces like a film but serves as a shock absorber, diffusing vibrations and impact stresses across the full bonded surface.

There are also two primary styles of foam PSA: open-celled and close-celled. The former will allow air and liquids to pass through, and the latter will not. Closed-cell foam tapes are an excellent option for gasketing and moisture sealing applications.

Here are several of the more common materials for foam automotive PSAs:

  • Urethane: As an open-cell foam, urethane will not provide solvent or moisture resistance. However, it excels as thermal insulation or a sound and vibration dampener. Note that urethanes do not perform well in exterior applications where weather and UV radiation will degrade them over time.
  • Polyethylene: This material produces an economical closed-cell foam tape that’s often selected for sealing applications. It is also a cost-efficient choice for insulating or cushioning.
  • Vinyl: Vinyl foams are closed-cell, highly flexible, and resistant to both heat and UV exposure. Automakers use them as sealing PSAs to block out dust, moisture, and light.
  • Acrylic: Exterior trims are often adhered with acrylic tapes, which have outstanding longevity and durability in extreme environments as well as strong adhesion.

Film Options

Most of the options below can actually vary wildly in forms and properties, depending on the specific formulation. It’s generally possible to find each one in transparent, colored, printed, matte, glossy, or other finishes as necessary. What holds this group together is that they’re straight-edged, thin-gauged, and better suited for smooth substrates than rough or uneven surfaces. Films are also the material of choice when you need transparent adhesives.

Here’s just a sampling of film material options and potential advantages:

  • Polyester (PET, polyethylene terephthalate): Mylar is an example of a polyester-based material. These films are light, durable, and optimal for protective shielding or as labels in areas that will experience high temperatures or chemical exposure.
  • Acrylic: Exterior automotive films that must endure harsh UV radiation often use this thermoplastic resin, which also boasts excellent clarity and stability.
  • Polyethylene: If you need a film that still repels chemicals, corrosives, and moisture, but has more conformability than polyester, polyethylene varieties are your PSA of choice. This is a common material in packaging and temporary protective films.
  • Polyimide: This high-performance resin is used for flexible circuit materials and other dynamic roles that take advantage of its high heat resistance as well as electrical and chemical traits.
  • PVC (polyvinyl chloride): PVC is known for its ability to resist wear, abrasions, a wide variety of chemicals, and weathering, but it loses strength in high heat applications (unless heat-stabilized).
  • Polyurethane: Some “clear bra” paint protection films utilize polyurethane-based formulas for their surface followability, clarity, and toughness in thin-gauge applications.
  • Fluoropolymer (PTFE, polytetrafluoroethylene): PTFE enjoys superior flexibility, a low coefficient of friction, and very little stickiness or tackiness on the non-adhesive side.  Like most synthetic films, it can also be used to repel chemicals and moisture.
  • Polycarbonate: Somewhat less common in automotive PSAs, polycarbonate nonetheless is easily thermoformed for film applications. It has outstanding optical clarity, impact strength, and dimensional stability, die-cuts well, and features excellent ink adhesion (unlike many plastics). This makes it a strong choice for labeling, graphic, and protective uses. 

Selection by Use Case

The purpose of the PSA is likely the first filter in your decision-making process. In general, films offer the best performance when you need an adhesive to be thin, clear, printed, or to act as a shield against liquid or abrasion. Foam PSAs are at their best when their flexibility comes into play, as with gap filling, shock absorption, sound dampening, or stretchable bonding between substrates with dissimilar thermal expansion properties.

For example, if you need a temporary protective solution — such as in packaging or shipping of auto parts — the economical price point and abrasion resistance of a polyethylene film, when paired with a low-tack adhesive layer that will leave no residue, makes for an easy choice.

However, if you’re trying to bond two rough or textured surfaces, a double-sided film tape will not perform nearly as well as a gap-filling foam tape. Flexible foams will hug uneven surfaces as the cells compress around and conform to irregularities, allowing better adhesive wet-out and bond strength.

Here is some brief advice on how to select the right automotive PSA for several common design problems and use cases:

  • High Temperatures: Polyester, vinyl, and polyimide films are highly thermal-resistant and often used in the extreme area of the engine compartment. PVC, while less resistant to heat, can be stabilized for high temperatures with a variety of additives.
  • Cabin Noise: Vehicle and component rigidity has a massive impact on cabin noise. Double-sided automotive film PSAs can boost rigidity and reduce noise from squeaks or rattles by providing a more consistent, full-surface bond than mechanical fasteners. However, anti-vibration foam tapes are even better when bond strength is less important than diffusing and silencing troublesome vibrations.
  • Bonding Dissimilar Substrates: Both foams and films can be fitted with a unique adhesive on each side (to suit the substrate), but foams often perform better here. This is because plastic and metal surfaces generally respond differently to heat. Even two plastics, like polyvinyl chloride (PVC) and glass-reinforced polycarbonate, may have very different thermal expansion ratios. The viscoelastic properties of foams allow the bond to flex as the temperature fluctuates. Acrylic foam tapes are a common choice for bonding plastic emblems and trim onto exterior metal panels.
  • Chemical Resistance: Most synthetic polymers enjoy high chemical resistance. Some of the more notable materials chosen to resist oil, gas, coolant, road salt, grime, and more include polyester, PVC, PTFE, vinyl, and acrylic. All can be suited to either film or foam formats, depending on your purpose.
  • Sealing and Insulation: Weatherstripping will often use closed-cell acrylic or polyethylene foam, which won’t permit the pass-through of moisture and will fill gaps with a tight seal. Urethane foams — which are open-cell — are not useful for sealing out moisture but excellent for dampening sound. Vinyl films are excellent blackout tapes where you need to cover production holes and prevent light from penetrating.
  • The Substrate Outgasses: Many injection molded thermoplastics will outgas over time, and they can create bubbles or blisters under film PSAs as a result. An open-celled polymer, while technically a foam, can be designed for use as a fine-celled, air-permeable “film” that is indistinguishable to the eye from other film PSAs. These blister-free films allow outgasses to pass through the cellular structure without creating bubbles and are often used for labels and bumper stripes.

This list provides food for thought, but there are many, many more potential considerations when selecting the right film or foam PSA for automotive purposes. It’s always best to consult with your supplier for guidance before requesting a quote on a particular PSA. They may have options you haven’t considered in their portfolio that could maximize the value of your purchase. Suppliers are highly motivated to earn your ongoing business, and they will be happy to work with you to find the best possible solution.

PET Film for Medical Grade Face Shields

PET film is a versatile material. It offers you dimensional stability along with tensile strength and transparency that can withstand the harshest demands. Because of its exceptional mechanical properties, it is an ideal material for a wide variety of uses and applications. From food packaging to plastic for laminating purposes, PET film offers you a performance advantage over other plastic materials.

With the emergence of the Coronavirus pandemic (COVID-19), PET film has also become a popular specialty film material for face shields. Medical grade face shields used as PPE provide additional protection against pathogens. They can be used alone or in tandem with other PPE such as using a face shield over a surgical mask.

PET Film Sizes for PPE Face Shields

7 mil and 10 mil are typically the sizes used for hospital grade protective face shields. By comparison, the average Coke bottle is 12 mil in thickness. PET film used for face shields is approximately double the thickness of a soda bottle. Due to the nature of medical uses for PET film face shields, hospital grade face shields are optically clear.

Metric Equivalents and Thickness

Note that “mil” does not mean “mm.”

  • 7 mil is roughly 0.007 of an inch or 0.21 mm. thick.
  • 10 mil is roughly 0.10 of an inch or 0.25 mm. thick.

Commercial Uses for PET Film

While our focus has shifted to PET film for face shields, PET film offers additional benefits that should be carefully considered when choosing a specialty film for your application needs. 

PET Film Grades and Clarity Options

Besides offering optically clear PET film for face shields, PET film can also be available in the following film grades:

Cannabis Packaging – From A Supplier’s Perspective

There is abundance of packaging suppliers that are getting into the Cannabis space. Here is quick perspective and what to prepare for taken from the May/June 2018 “ Healthcare Packaging “ magazine.  This is a perspective taken from those who supply packaging material.

Child Resistance and Blisters: With any marijuana product, child-resistance is an important piece of the puzzle. Flexible packaging and Blisters will play an important role. Plastic “exit pouches” are required at the point of purchase in some states’ cannabis dispensaries, and these must include a certified, child-resistant feature.
“On the marketing side, most cannabis manufactures are not blister packing yet. It’s a way to set your product apart from the typical bottled soft gels and capsules,” says Wes Mancoff, President of Thomas Packaging.
Nancy Warner, CEO of Assurpack, states, a pharma packaging industry veteran who supplies only child-resistant packaging, notes “People are starting to use primary blisters. The industry ti trying to be legitimate. They should take the highest level of precaution, so I always tell people you have to use F1 because you don’t know otherwise, and how can you support anything less than that?”
And what about sustainability? Most people want recyclable materials, but this can be difficult to balance with the need for child-resistance. Additionally, many cannot afford these options.

Products: While flower is still common, the sheer number of delivery methods is staggering; edibles and infused products are rising in popularity. “A lot of medical patients don’t want to smoke the flower either for health reasons or they are limited in where can smoke,”, says Mancoff. “Capsules and soft gels with extracted THC and/or cannabidiol (CBD) are an easy delivery method that can be consumed discreetly.”
Aside from patient preference, laws in some states may help the edible market become as large, or larger, than that of flower. “Some states-like Pennsylvania at the moment – are passing medical marijuana laws that only allow concentrates and edibles, as supposed to flower,” says Chris Trabbold, Field Service Manager at All-Fill Inc., which supplies cannabis companies like Kiva Confections with packaging machinery.

Automation: Not all, but many edible are still produced in kitchens, not factories. “Most packaging is still semi-automatic with the edible world. But for flower, oils, cartridges and tinctures, people are using more large scale filling machines,” says Werner. “They’re not purchasing a bottle line that goes 300 per minute, but more like 50 per minute. Eventually there will be a lot more equipment demands.” Warner says she works a lot with preformed blisters, foil, cards and simple heat-sealing machines.
“Because it’s still federal illegal, you can’t ship across state lines. One thing we’re seeing is companies planning to open facilities in every state where cannabis is legal, “ says Mancoff. Some producers have even considered purchasing equipment and driving it across state lines to their different facilities because production requirements are small enough.

Future Planning: Where at Cheever we supply several different packaging manufacturers with various films and paper, we get to see firsthand some of the requests or questions they are facing first hand. If you are thinking of expanding your packaging, please gives a shout to pick our brain, we would love to hear on your project.

Why The Specialty Paper Price Increase

Is it just me, or did everyone stick their head out their corporate window around the end of last year and yell “Price increase 3%-5%!!!”. If you are reading this post, than you are all to familiar with getting these emails from your suppliers. We put together over the last several months exactly what we have seen and heard from our suppliers and customers and here is our state of things below.

 

The main drivers we have seen that attributed to this increase are the following:

Truck Driver Shortage:

  • This has been an issue for several years with some estimates putting that number at 100,000 for 2017 (www.truckinginfo.com/channel/drivers/news/story/2016/12/state-of-trucking-for-2017.aspx )
  • During periods of strong demand this creates a large imbalance driving up prices
  • The current load to truck ratio is 7.2 to 1 ( on average for every 1 truck available there are 7 loads that company or driver can select from)The current average cost per mile paid to trucks is $2.10 the highest in over 3 years
    ELD Data Log Mandate ( begins 12/18
  • Transit times will be extended as trucks will now only be able to legally run 450-500 miles per day on average.
  • One day transits become two days, two day transits become three days and so forth.
  • Reduced Capacity ( even more ) fewer miles being run by some carriers and other carriers will leave market all together because they can’t or won’t comply
  • Dynamic Rates – Examples above will drive prices up even further for 201

In short , carriers and trucks are King right now. Those that can capture capacity are paying for it. That is why you’ve seen a significant increase in rates and why we believe they will only continue to rise in 2018.

Natural Disasters:

  • Three Hurricanes devastated Houston, Southern Florida and Puerto Rico, Creating massive demand for inbound trucks and supplies at any price.
  • This pulls from an already depleted pool of available capacity and creates an additional imbalance in the national trucking network.
  • Increasing rates considerably to haul products into areas affected by the Hurricane and shifting normal traffic flows.
  • Oregon and California Forest Fires causing road closures and additional network disruption tightening an already seasonal shortage in the Pacific Northwest.

NBSK Pulp:

  • This is main pulp used for specialty base paper. This past December this wat $1,185/ton. April pricing is $1,280/ton. (RISI Published pricing for NBSK). After speaking with several mill reps and buyers, they are not seeing a quick end to these increases.
  • The mills have quite a few levers they can use to raise pricing, these levers are the ones mentioned above.
  • The demand for pulp and the Amazon effect is real. When you go out to get that package today on your stoop from Amazon, take note that it is almost always in a box. The MF (machine finished ) and MG (machine glazed) grades are extremely in demand for making corrugated boxing.
  • Several mills we deal with, are not taking orders due to their paper machine assets are booked solid – great problem to have if you are mill, not so good for the rest of us. Right now we have customers calling to see if we can offer lower pricing, only to find out, everyone they have spoke to, has also raised prices. With this we have seen customers asking to review their current material and see if their is an alternative, like using a film for their release liner. In some cases their can be some savings.

6 Packaging Trends for 2018

CMO Pam Webber from 99desings has provided what she is seeing as the Big Six design trends in packaging. If you have not heard of 99designs, super cool site where this is an online graphic design marketplace that connects freelance designers with business seeking everything from package design to logos. (We used them to create our current logo that you see on our Cheever website today)
We figured with the amount of requests they do in this space for packaging, hearing what Pam had to say is some good tribal knowledge – so here we go.

  1. Simplicity. Using less language will keep you in sync with our fast-paced society. People race up and down the food isles so keeping things simple is a way to get noticed. Keeping things simple plays an important role in helping us access our intuitive side
  2. Pastels. Pastels feel like a natural reaction to the hyper-stimulation and explosive colors we’ve been experiencing. They speak to our softer side and give products a candid and warm aura, which is translated into a pleasant and welcoming message for the potential customer. This translates in feminine, calming package designs that are starting to see a resurgence.
  3. Doodles. Go figure that when Doodles are see on a package, doodles can turn a product into a fun universe that was born from someone’s imagination and shared with the world. Everyone loves Doodles from 3 to 90 year olds.  It is this “raw” un-edit, let-your-guard” down approach that shows the consumer – “hey I’m just like you”
  4. Standout Shapes and Material’s. When needing to build a brand or re-brand, having this “extreme packaging” showcases the thoughtfulness and ingenuity your product brings to the market.
  5. Vintage. Going with an old school design demonstrates and give the feel that you have a dedication to a certain level of quality, and it tells a story of tradition, respect and passion. These are elements that remain alive-from a design standpoint-through organized structure, dense details and strong, lasting identity. People love to see early turn of century workers “making” things with their hands or showing the hard work it took back then to make something great. It is also shows the passion the workers have for their product and company that really bleeds through to your audience. Think Chevy commercial “Like a Rock” and several others.
  6. Vibrant Gradients. The use of gradients seems to be making a comeback. We are seeing more and more colorful gradients, adding depth, and form to package design.

What Is Disrupting the Specialty Paper Market

In the next 5 years, these four technologies are set to increase capacity and enable new product opportunities for the makers of specialty papers.

According to the new Smither Pira market report – The future of Specialty Papers to 2022, steady growth will continue through the end of the decade at 2.2% per year to push this to 26.98 million tons in 2022.  The technologies that will contribute to this are the following: Foam Forming, Precision Control on Large Format Machines, Industry 4.0 and Stretchability.

Foam Forming

Foam forming is a papermaking process that can produce nonwoven-type materials on paper machines with excellent formation uniformity, porosity and bulk.

Foam forming is a multi-phase fluid system structured by the presence of gas bubbles separated by thin liquid films.  The bubbles impart increased sheet bulk and porosity to the paper.

New systems employing foam forming are now entering commercial production due to a series of recent technical refinements.  A key focus is maintaining sheet strength while not compromising the enhanced paper bulk.  The process of employing cellulose nanofibrils (CNF) is reporting a 16-19% improvement in tensile strength.

Paptic’s extensible paper bag stock which offers a more environmentally friendly substitute for plastic is the first product to come from the foam forming development.

Precision in Papermaking

What we are seeing is state-of-the-art precision technology being developed for the commodity grades what will steadily find a wider use on specialty machines.   Some of the key benefits from this are, reduced product variation, which in turn results in tighter specifications with less waste from changeovers, rejected lots or over-designed products that use excess fiber to cover poor variability and reproducibility.

The biggest impact we will see is the implementation of precision technology on faster and wider papermaking machines allowing them to compete in the specialty spaces that have always relied on slower, labor intensive papermaking.

Industry 4.0

This ability to gain data and information on various pieces of equipment and then sharing this data so it makes sense to other components is what the industry is calling Industry 4.0.  Computers have been used in the paper making process since the 60’s.  What is happening today is, the quality system and the technical process are all talking to the supply chain and letting them know when to order material, or spot a trend with something happening on the paper machine.

New on-line sensors or “eyes” have increase drastically in the last 5 years.  The key benefit is first they are able to be programmed to detect an abnormality, but the real win is this data can be saved and graphed to show trends.

An example of this trend is the evolution of headboxes with the online CD basis-weight profiling.  The headbox slice is kept as straight as possible, but the excess weight is a small area is corrected by injecting water in narrow segments to displace just the excess fibre.

Stretchable Papers

Imagine a paper that can achieve a base sheet with a 20% stretchability in the machine direction and 16% in the cross direction.  Initially developed in Europe by Gruppo di X, and beta tested with Innventia in Sweden, the capacity to develop stretchable papers is now a commercial reality via a licensing deal with BillerudKorsnas in Europe.

End products include tray-format packaging and pharmaceutical blisters for stiffness and advertising, paper cups and other liquid containers as well as decorative foils for furniture.  This stretchable paper is intended to replace plastics with natural paper webs.

As we can see from these four examples, the creating and using of data is starting to play a larger roll in the paper industry.   This will help us to bring products to market faster and save costs.  Where logistics is such a big part of Cheever, we have already seen our warehouse software go through updates forced on them by customers looking to see their data in different ways.  We are now able to provide this data in a daily email showing the customer their inventory on our floor.

US Box Shipments Outpaced GDP – Why This Is Big News

2016 was a big milestone in the production and manufacturing of container-board and corrugated boxes.  According to Vertical Research Partners, corrugated box shipments in the US expanded by 2.1% on an annual basis, to 376 billion square feet, surpassing the country’s GDP growth of 1.6%.

This is big news when you look at the trend over the past years.  From 1984 until 2016 box shipments grew by just 1.1% per year, when the US GDP for the same period averaged 2.6%.  Ok great, so everyone would lump this together in the paper space and say, with paper usage falling behind over the past years, and plastic film has taken over in packaging, it would make sense box capacity has slipped.

But just hold on their folks, that is why this milestone is big news.  And now the Ahh Haaa Moment – wait for it, wait for it —– Amazon!!.   When was the last time on your front stoop was a plastic box of your Amazon goods – let me answer – never.  That’s write – corrugated box.  And I know you are saying, there is just no way, that with the takeoff of Amazon it signal handily increased this number past the GDP.

Well it is not 100% Amazon, but they are the main factor.  The other driver is eCommerce is common place today, everything is shipped in a box.  So is this just a blip or are we in a trend?  Data so far this year points to a trend.  US box shipments are up 2.8% year-on-year from January until July.

The other key point to watch here if you are an Investor, maker or supplier is pricing of the material.   In the past quarter-century, the global corrugated box industry has doubled and right along with this has been the need for OCC – old corrugated containers.

So just follow me for a second here.  80% of global containerboard capacity is predicated on the use of recycled fiber.  Meaning rarely is virgin soft wood used to make corrugated boxes.  Here is the interesting part.  With the recycling of corrugated boxes, the fibers break down so they are not as strong, so it is not like we have this endless supply.  After a couple of cycles, the material is no longer able to be used.

What we are seeing now is we are starting to use all of the recycled corrugated box material in the market, and we are starting to see virgin Kraft being used to fill the void.  The concern here is the regions with this attractive softwood trees for containerboard production are limited.  As a result, global corrugated box prices could rise a bit faster than inflation.

We at Cheever have seen these requests from new and existing customers asking for different coatings, colors and textures.  Definitely an exciting time to actual be in a growth mode when we are talking in the paper space –  this time around we are ok being “boxed” in..

First Modern Ag Residue Paper Plant in NA Under Construction

Making Paper out of Wheat Straw – the first modern paper mill is officially under construction in the sate of Washington to make this happen.

“On September 27 FeedStock (Chicago, Ill., USA) reported that for the past 15 years, environmental not-for-profit Canopy (Vancouver, Canada) has been advocating making paper from commercial agricultural residue a reality. Columbia Pulp, the first modern mill of its kind, is now slated to make pulp for paper and packaging out of wheat straw; it is now officially under construction in the state of Washington.

By securing the support of large consumer corporations and creating focused demand, Canopy claims it has helped position straw papers and packaging as a strong alternative to products made with virgin tree fiber. Through Canopy’s Second Harvest initiative, corporations such as Staples, EarthColor and more than 100 fashion brands have expressed clear interest in buying agricultural residue paper, packaging and/or textiles as they become available.”
