  • Engineering the correct release level: Depending on your use we can provide a very easy release of 30 (R19c test method) to a very tight release of 300.
  • Customizing key elements: Our skilled network of experts can customize adhesive, release level, caliper, flexibility and color. 
  • Creating industry leaders: We curate customized, high-performance adhesives pairings that help our clients succeed.  
  • Custom Solutions, Cost Savings: Cheever Inventory Hold Program can provide you with critical cost savings on large orders of release liner. Learn more here

Silicone Release Liner Paper Grades

In its simplest form, silicone release liner is made up of 3 separate parts all acting together: the base paper or substrate (often Kraft paper), the barrier coating, and the silicone. We source the raw materials and convert them to the exact finished product you need:

  • Custom coatings: 1 or 2 sided
  • Slitting Capabilities: custom slit widths
  • Sheeting Capabilities
  • Die Cutting Capabilities
  • Printing
  • Traverse Winding

Super Calendered Kraft (SCK) - Bleached and Natural

A popular paper for release liner due to its hardness, smoothness and caliper consistency. The properties are achieved by taking Kraft paper and running it through a Calender stack which produces a very flat paper that has a dense, closed surface.

Clay Coated Paper

A Kraft paper that has one coating of clay and a second coating of silicone. The clay coating adds  additional dimensional stability as well as increased tolerance for high temperatures. 

Glassine Release Paper

 A highly smooth paper with an optimal surface for silicone coating. Excellent for die cutting due to its very narrow caliper tolerances.

Silicone Release Liner Application/Industry Areas

Label Stock

The label industry is one of the largest users of silicone release paper. It is used to protect the print on the face-stock from the adhesive on a label. Release liner labels are used in point-of-sale labeling, primary labels for the food and cosmetics industries and business system labels. Other uses are for functional and security labels on machinery and industry equipment.

Building/Roofing

When used in a roofing application they are chosen for the cold self-adhesive membranes as well as self adhesive under layers. The liner protects the adhesive surface and ensures the final product can be rewound after production. A release line is also used in self-adhesive shingles.

Shipping Envelopes

Document pouches used for overnight shipping will have a peel & seal closure strip. The release liner is part of this system, where it is removed to expose the adhesive before pressing closed. Used in food bags, business forms, paper envelopes and document pouches.

Fiber Composites

Composite material is used in wind energy, automotive and aerospace to name a few. The release liner is used as a process paper or film to prevent material from sticking together during the impregnation process.

Medical

The release liner is being used in almost every area in the medical field. Typical used in body electrodes, adhesive bandages, therapeutic patches, wound dressings and transdermal deliver systems.  In the example of ECG/grounding pads, the release liner is used to back the adhesive. Where these products are used directly in contact with the skin, a high quality release matched to the correct adhesive must be used and be able to be made at a consistent level. We have been working with manufactures in these fields helping them to produce high-quality release liners as well as service solutions around these products such as, narrow split, coils, double packaging, plastic cores or bio burden testing. Other uses of release liner are, wound care, PU casting liner, surgical drapes.

Hygiene

Hygiene applications utilizing a release liner are primarily used for self-adhesive diaper frontal tapes and feminine care products (sanitary napkins/panty liners). We offer services for these liners by providing printing, coating and slitting operations if needed.

Graphic Arts

With this market growing by leaps and bounds, the release liner that is often used in these applications has had to adapt. Advertising films such as PVC, PP, PET are being used in car wrapping, reflective safety films and decorative vinyl’s. The release liner used with these films is key in making sure there is good lay flat characteristics, dimensional stability and adjustable release levels. We will work with you to help you tailor a product solution for your specific application.

Functional Coatings

A functional coating can be described as a “layer” over the substrate which could be paper/PE/film. This layer is providing a protection from the elements – rain, static, heat, slip/grip, absorption. One use of this in taking a Kraft paper coated with a cold seal adhesive. This enables to seal and wrap items without the use of tape or glue. It will form a strong bond at room temperature only when pressed together. Used in corrugated boards, for protecting put together do-it-yourself furniture and automotive parts.
