Top 5 FAQs About Paper Release Liners

Paper release liners are the original backbone of the pressure-sensitive adhesive industry. Used as a carrier to many types of adhesives and tacky substances, paper release liners keep the adhesive clean, usable and maintain the adhesive’s integrity until its ready to be released from the liner for its next steps. Paper release liners are produced with a base paper layer and a silicone release layer, the construction allows the release of the adhesive material when needed.

What Types of Papers Are Available For Release Liners?

Release liners are constructed of several base paper substrates – each with its own performance characteristics. Release liners are not one-size-fits-all products. Identifying what paper substrate is most appropriate for your release liner application is best determined by working with an experienced Fox River Associates representative who will work with you to understand your specific needs.

Fox River Associates offers a full breadth of paper release liner substrates.

Direct Coated Papers – Glassine and Super Calendared Kraft (SCK). These papers are high in strength and can be coated on one side or on two sides for versatility in many market applications. These papers can be coated with a differential release, resulting in a “tight” and “easy” release on the same substrate. These are mainstay substrates for paper release liners.

Clay Coated Kraft – these kraft papers have an extra layer of clay coating delivering excellent layflat and dimensional stability. These paper release liners are less reactive to moisture and temperature than other available substrates. The consistent surface and smoothness of these clay coated papers make them excellent base substrates for release coating for paper release liners.

Poly Coated Kraft – the poly coating provides enhanced moisture resistance. These liners are durable and highly resistant to tearing. They can also provide a very smooth surface to the coated adhesive

Specialty papers:  machine finished, machine glazed, and machine calendared papers are specialty substrates that may be found in paper release liner applications that require performance characteristics outside the standard papers used for release liners.

Which Paper Substrate Is Right For My Market Application?

The vast variety of paper substrates available for paper release liners ensures that each application can have the most appropriate liner for its needs. Working with an experienced representative from Fox River Associates, you can identify the optimum designed liner for your processing, manufacturing, and final product requirements. There are some general guidelines for understanding common paper release liners for market and application.

Medical:  applications for paper release liners include wound care, electrodes, ostomy appliance, medical tape/securement, transdermal patches, and wearable medical devices. Paper release liners used in these medical applications include direct coated glassine and SCK release liners, clay coated release liners and polycoated kraft release liners.

Tapes:  applications for paper release liners include single coated tapes and double coated tapes. Paper release liners used in these tape applications include direct coated glassine and SCK release liners, clay coated papers, and polycoated kraft release liners.

Composite and Aerospace:  applications for paper release liners include composite panels, fabric prepreg, resin film and uni-directional tape. Paper release liners used in these composite and aerospace applications include direct coated glassine and SCK release liners, clay coated papers and limited use polycoated kraft release liners.

Building and Construction:  applications for paper release liners include anti-skid/surface, ice & water, seam tape/flashing, soundproofing, underlayment and waterproofing. Paper release liners used in these building and construction applications are direct coated glassine and SCK release liners.

Industrial:  applications for paper release liners include die cut and kiss cut parts, foam gaskets and foam packaging. Paper release liners used in these industrial applications include direct coated glassine and SCK release liners, clay coated papers and polycoated kraft release liners.

When is Paper Preferred Over Film for Release Liners?

Paper release liners and film release liners are both widely used in all market applications from medical and industrial to tapes, composites and building and construction.

Paper release liners offer excellent printability, they are permeable and breathable, and they are heat resistant at warm to moderately hot temperatures and can act as an insulator. Paper release liners also offer improved stiffness and rigidity over film release liners. Varying surface COF of different silicone coating types on paper release liners can help with processing the liner in your application. And some paper release liners can be designed to tear when that is a feature desired for the unique application.

The Fox River Associates team can help explain the features and benefits of paper release liners and film release liners to help ensure you identify and specify the appropriate release liner for your application. Use the form on this page or message us at info@foxriverassociates.com today.

What Adhesives Are Paper Release Liners Compatible With?

There are many different adhesives and chemical compounds that paper release liners are designed to be compatible with. Common adhesives include acrylic, hotmelt, removable and rubber adhesives. These adhesives are found generally in medical, tape, label, and graphic arts, industrial and even specialty converting applications.

Specialized adhesives such as hydrocolloid and hydrogel adhesives are found in medical applications using paper release liners. Paper release liners in the aerospace & composites industries are often used to carry hot melt cyanate ester resin, hot melt epoxy resin, misc. hot melt resins and solvated resin systems. In addition to acrylic and hot melt adhesives, paper release liners in the building and construction industry can also be used to carry butyl.

When working with your Fox River Associates representative you’ll want to talk about the adhesive and chemical you’re coating along with the expected coat weight and desired release force.

What Do I Need To Know About The Release Coating On Paper Release Liners?

Release coatings, often silicone coatings, are designed to provide release force that is compatible with the adhesive or sticky chemical being coated, as well as with the method of removal of the release liner. What is most critical is that your adhesive can be cleanly and easily removed in your operation, with minimal to no loss of subsequent adhesion.

Silicone release liners are designed with various release forces that are targeted for intended applications. Often referred to as easy, medium, or tight release, the release force should be stable under your intended manufacturing and processing environment.

Release agents are often silicone, but not always. Silicone adhesives, for example, cannot use silicone release agents. Special fluorosilicone release agents are designed to be used with silicone adhesives.

Are Paper Release Liners More Cost Effective Than Film Release Liners?

Paper release liners are used where cost effectiveness and versatility are needed. However, cost should not be the primary determining factor when choosing a release liner. By working with an experienced release liner supplier, like Fox River Associates, you can be assured that you’re using the most appropriate release liner for your application – identified for high quality performance and efficient manufacturing processes.
