Silicone Release Liner being removed

Silicone release liner papers are used in a wide variety of everyday products and applications, from bandages to shipping envelopes. Because of the natural properties of Silicone, these release liners can securely hold adhesives, but make removal quick and easy. With just a little pressure, an adhesive product can be removed from the Silicone release liner, leaving no residue behind.

Cheever silicone coated release liners are engineered to ensure perfect tack and easy peel-off for pressure-sensitive adhesives. We provide our clients with expert guidance to achieve the right combination of materials and conversions for their specific applications. 

Silicone Release Liner Paper Grades

In its simplest form, a 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

This is 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

This silicone release paper is 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 an increased tolerance for high temperatures. 

Glassine Release Paper

This release liner paper is a highly smooth paper with an optimal surface for silicone coating. Excellent for die-cutting due to its very narrow caliper tolerances.

Applications and Industries for Silicone Release Papers

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. Silicone release liner labels are used in:
 
  • point-of-sale labeling
  • primary labels for the food and cosmetics industries
  • business system labels
  • functional and security labels on machinery and industry equipment

Building/Roofing

When used in a roofing application, Silicone release liners 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 liner lis 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.

Silicone release papers are used in:
 
  • Food bags
  • Business forms
  • Paper envelopes
  • Document pouches 

Fiber Composites

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

Medical

The Silicone release liner paper is being used in almost every area in the medical field. 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 manufacturers 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 bioburden testing.
 
The Silicone release liners are typically used in:
 
  • Body electrodes
  • Adhesive bandages
  • Therapeutic patches
  • Wound dressings
  • Transdermal delivery systems  
In the example of ECG/grounding pads, the release liner is used to back the adhesive. Other uses of release liner are, wound care, PU casting liner, surgical drapes.

Hygiene

Silicone release liners in hygiene applications 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 vinyls.
 
The Silicone release liner used with these films is critical in making sure there are 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 provides protection from the elements – rain, static, heat, slip/grip, absorption.
 
Kraft paper coated with a cold seal adhesive, for example, enables you 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.
 
Functional coatings for Silicone release papers are used in corrugated boards, for protecting put together do-it-yourself furniture, and automotive parts.
