What is a release liner?
Description:
A release liner, also commonly known as a release paper or release backing, is a
type of coated paper
or film that is used as a protective layer or carrier for
adhesive-coated materials.
The key characteristics and uses of release liners include:
1. Substrate: Release liners are typically made of silicone-coated paper, polyethylene, or
polyester film.
This provides a smooth, slick surface.
2. Adhesive Protection: The release liner is used to protect the adhesive side of materials like labels,
tapes,
films, and other coated products before they are applied to a
surface.
3. Easy Removal: The release liner can be easily peeled away from the adhesive when it's time to
apply
the product, leaving behind the sticky surface.
4. Temporary Carrier: The release liner serves as a temporary carrier or support for the adhesive-coated
material, allowing it to be handled, die-cut, or converted more
easily.
5. Applications: Release liners are commonly used for self-adhesive labels, tapes, decals,
protective films,
and other adhesive-backed products across industries like
packaging, manufacturing, and graphics.
The main purpose of a release liner is to preserve the adhesive properties of a product until it is
ready to
be applied to a surface, while also enabling efficient handling and
converting of the material.
