Learn more about Pattern Coating adhesives
Pattern adhesive coating is the process of creating lanes of adhesive coverage and lanes with no adhesive coverage across the web of pressure-sensitive paper or film facestocks. Instead of coating the adhesive uniformly across the web, a process is used to remove adhesive in certain areas. The process is also referred to as zone coating. Pattern coating is typically used with challenging label surfaces which require a heavy adhesive coat weight.
Here are some of the questions we regularly receive about pattern coating:
WHEN SHOULD YOU USE A PATTERN ADHESIVE?
From a product standpoint, the decision to pattern coat the adhesive is driven mostly by the need for a heavy coat weight adhesive. Customers request a pattern adhesive in this case because the coat weight of the adhesive can create tacky edges on the slit rolls. The pattern is used to create lanes without adhesive at the location of the slit – eliminating tacky edges, which can cause issues on press with adhesive buildup. This pattern prevents the adhesive from flowing into the slit edge and causing converting issues.
We also pattern adhesive for customers who do not want to deaden adhesive on press or do not have the ability to delaminate the liner on press to apply the deadener. Deadening an adhesive is the process of applying a chemical to the exposed adhesive on press that removes the tack of adhesive.
In other cases, the end use drives the pattern request. Popular end-use applications for pattern adhesive are shelf markers and lift tabs. The dry adhesive lanes provide non-adhesive areas which create the tab or provide both a pressure sensitive and non-pressure sensitive label. Pattern coating can also reduce surface contact, and, in some applications, can provide easier removability.
HOW DOES ACUCOTE IMPLEMENT PATTERN ADHESIVES?
Acucote pattern coats in-line and thus we are able to place the pattern exactly where our customers need them. This bar is mounted between the coating station and the thermal curing ovens in the adhesive coating line. We coat the full web with adhesive and then we remove the adhesive from the desired zones using the pattern bar. The adhesive from the web that is removed by the bar is then recirculated back into the adhesive reservoir. Each pattern bar is custom designed for the customer’s specific end use and slit widths.
WHAT TYPES OF ADHESIVES CAN ACUCOTE PATTERN COAT?
We pattern all Acucote adhesives excluding microspheres.
WHAT ARE THE MINIMUM AND MAXIMUM SIZES OF PATTEN COATED LANES?
We create linear patterns with a minimum adhesive coverage of 50% across the web. Non adhesive lanes can be up to 3” with a minimum of 1/8″ lane. Our process has a minimum adhesive lane requirement of 3/8”. Patterned products with over 3/4” of non adhesive lanes are routinely perforated on the back of the release liner to relieve the trapping of air on press.
HOW CAN I ORDER PATTERNED ADHESIVE?
Acucote customers can work with their sales representative and the Acucote Applications Development Team to develop their specific pattern specification. All pattern products require customer-approved drawings that show the pattern. These patterns are reviewed and approved by Acucote’s technical team. The minimum order quantity is the master width by 5,000’.

What is FSC?
As brand owners are looking for long-term sustainable solutions, our customers look to Acucote for sustainable materials. This Acucote Insights provides a brief description of what constitutes FSC®-certified material and how Acucote can support you with these materials.
WHAT IS FSC?
FSC stands for the Forest Stewardship Council. The FSC is an international nongovernmental organization which implements and enforces the rules governing the responsible use of wood products. The goals of the FSC include sustainable forestry and maintenance of basic human rights for all who are working in harvested forest goods.
WHAT DOES IT MEAN TO BE CHAIN OF CUSTODY CERTIFIED?
A FSC Chain of Custody [CoC]-certified organization agrees to uphold and conform to the environmental and human rights rules maintained by the FSC.
Acucote is a FSC Chain of Custody-certified organization. CoC-certification is tailored to entities that are not harvesting or processing wood products as a primary business but that are purchasing wood products. A CoC organization agrees that it will not modify the wood products in any way that will change the wood characteristics.
FSC CoC-certified organizations are allowed to purchase FSC controlled wood products, process them in accordance with the FSC rules, market and sell the goods as FSC CoC-certified.
WHAT KIND OF FSC MATERIALS DOES ACUCOTE OFFER?
FSC CoC-certification applies only to products made from wood pulp – including paper facestocks and paper liners. Acucote purchases FSC CoC-certified paper, adhesive coats the paper without modifying the wood characteristics of the paper and resells the paper as FSC CoC-certified.
FSC CoC-certification is specific to certain goods. Because of the fees to administer the FSC program, materials that are FSC Certified are typically more expensive and may have a longer lead time.
Our FSC portfolio includes gloss and matte papers, foils, mail tabs, a variety of boardstocks, thermal transfer, laser, dye and pigment facestocks as well as a handful of liners including layflat.
DOES A CONVERTER ALSO NEED TO BE CHAIN OF CUSTODY CERTIFIED?
Converters also need FSC CoC-certification in order to market and sell goods as FSC CoC-certified. Acucote’s FSC CoC does not “transfer” to our clients.
HOW DO I BECOME CHAIN OF CUSTODY CERTIFIED?
If you are not FSC Certified Acucote can connect you with printing alliance groups that can help you get certified quickly.
HOW DO I KNOW IF A PRODUCT IS FSC CERTIFIED?
Acucote FSC CoC-certified materials are packaged with the well-known check tree symbol. This symbol confirms that Acucote has conformed with the principles set forth by the FSC in processing products.

Acucote Insights: Sustainable Terms & Materials
Biodegradable, Compostable, Recyclable, and More
In today’s marketplace, your customers are demanding long-term solutions so that brand owners can reduce environmental impacts and climate change. The abundance of terms and product options used in the “sustainability movement” can be complex and confusing. This movement is based around the use of materials and methods that promote, recycle, reuse and limit the impact on the environment.
Our Application Development Team frequently helps converters become “Sustainably Savvy” by providing general guidance on the common terms and product options that enable them to take the next step in solving their customers’ sustainability inquiries. We’ve captured and defined some key product terminology for this issue of “Acucote Insights.”
Primarily paper or plastic products that can be treated or processed for reuse. Materials must go into an established processing stream such as a recycling bin. As a result, these materials can be recovered and remanufactured into similar materials. Some polyesters are recyclable but there are not many outlets for polyester recycling. However, techniques for recycling adhesive coated polypropylene are being developed. Uncoated paper is naturally recyclable but Acucote adhesives and coatings are generally not recyclable. They interfere by creating scrap in the paper making process.
Recommendation: Paper or plastic facestocks paired with Acucote’s GPX, Arctic, GR7, SX78 or EF701 adhesives.
Materials that can be used to remanufacture paper. Some labels with a paper face and a repulpable adhesive can be remanufactured into paper using the conventional pulping process.
Recommendation: Acucote GPX, AT4505, SX78, GR7, Arctic, EF701, GPX BO and SX78 BO, RE10 BO and RE10 adhesives are certified repulpable and when used with paper facestocks are sustainable options.
WASH OFF ADHESIVES
An adhesive that allows the label to be easily separated from a container when exposed to water. The label is then thrown away and the container can be recycled in its designated waste stream without causing contamination.
Recommendation: Acucote WOff wash off adhesive is a water-based acrylic emulsion made with non-APEO surfactants.
Paper products made from forests that are managed to be sustainable. FSC COC certified recyclable content and reclaimable materials come from wood that has been harvested with little impact on the climate. Most paper products are now available to purchase as FSC certified.
Recommendation: Acucote’s popular offerings include 60# Semi Gloss, 60# Matte Litho, thermal transfer, foils, fluorescents and dye and pigment stocks. . FSC certified 40# and 50# CCK liners are also available.
Paper and film products that contain some percentage of recycled material. Material can be created from pre or postconsumer waste products. The paper waste products are made into pulp and then again into paper. The film waste products are melted down and made into more film.
Recommendation: Acucote offers 60# Hemp paper that is made from 75% post-consumer wood. 8pt Recycled C1S is created with 10% post-consumer waste. .92, 1.2 and 1.5 mil PET liners are created with up to 50% recycled resin. Additional materials can be sourced with pre or post-consumer waste
ENVIRONMENTALLY BENIGN COATINGS
Coatings that have been TLMI EBA certified and break down into compounds in natural conditions that cause minimal harm to the environment. Paper with an environmentally benign coating can be safely landfilled without harm to the environment.
Recommendation: Acucote adhesive EF701 is certified TLMI EBA as environmentally benign.
Products can be safely landfilled and are certified by third party testing. Certified compostable products are tested for a period of 6 months to confirm there is a 90% breakdown in known environmental conditions (dirt and certain microorganisms). The
test standards include ASTM D6400, ASTM 6868 and EN13432. Generally, third party testing is performed on the finished label so that inks and varnishes are included in the testing.
Recommendation: EarthFirst PLA, Acetate and Acetate UD facestocks are ASTM D6400 certified compostable. CP1 adhesive, when combined with certain facestocks, inks and packaging has been certified for composability by end users.
Over time, these materials are able to break down by living organisms. Biodegradable products can be safely landfilled and can be certified to ASTM biodegradable standards that ensure the materials break down into common substances found in the soil.
Materials can also be non-certified as they breakdown within a timeframe outside of the standard.
Recommendation: Acucote’s CP1 adhesive is made from biodegradable materials. CP1 has been tested by a third party
and contains 98% biobased content. Acucote’s CP1 adhesive and EarthFirst PLA, Acetate and Acetate UD facestocks are biodegradable. Paper facestocks are generally recognized as biodegradable.
WATER DISSOLVABLE ADHESIVES AND FACESTOCKS
A water dissolvable label breaks down the face and adhesive completely when exposed to water by disintegrating the label. As a result, it is a popular choice in food service labeling (materials dissolve in the dishwasher). This allows for clean separation
of the facestock and adhesive from the container, which can then be reused or recycled in its designated waste stream.
Recommendation: Acucote’s DS1 adhesive is designed to disperse in either cold or hot water, leaving zero residue. DS1 adheres to metal, HDPE and other LSE plastic containers. Pair DS1 with Acucote’s 40# Water Soluble Litho or 47# Water Dissolvable Direct Thermal – both dissolve completely when immersed in water.
Ask your Customer
As with any new label application, understanding your customer’s sustainable goals are critical to providing the most appropriate solution. In order that the Acucote Applications Team can suggest sustainable labeling alternatives we need to understand your customer’s recyclable pathway and sustainability initiatives. Here are the type of questions you should consider:
• What is the container being labeled?
• How will the packaging be disposed of?
• Is recycled content enough?
• Will an FSC label suffice?
• Does the label have to biodegrade in 6 months?
Acucote has built its reputation around solving application challenges. Our team stands ready to help you navigate the rough waters of these challenging product recommendations and help you become “Sustainably Savvy.” If we don’t have the right product combination, we’ll quickly develop and source it for you.
