Ir al contenido Kangchuang Paper manufactures silicone release paper — precision-coated paper with a cured silicone release layer that provides controlled, consistent peel-off separation from adhesive surfaces. Our release paper is used as the carrier liner for pressure-sensitive adhesive labels, adhesive tapes, graphic films, medical adhesive products, composite prepreg materials, and industrial die-cut adhesive components. Available in glassine, super-calendered kraft, and clay-coated base stocks with single-side or double-side silicone coating, release force from 5g/inch to 400g/inch, in rolls from 50mm to 1,600mm width. Factory-direct from Dongguan with free sample rolls shipped via DHL Express to the United States.
Release Paper
Silicone coated release liner paper on glassine, kraft, and clay-coated base stocks — for pressure-sensitive label converting, adhesive tape manufacturing, graphic film lamination, medical adhesive products, and composite prepreg layup applications.
Release paper (also called release liner, silicone paper, or peel-off paper) is an industrial paper product with one or both sides coated with a thin layer of cured silicone that provides a non-stick release surface. The silicone coating creates a surface with extremely low surface energy, which means that adhesive materials — pressure-sensitive adhesives, hot-melt adhesives, and thermoset resins — do not bond permanently to the paper surface. Instead, they peel away cleanly and completely when separated. This controlled release property makes release paper essential as the carrier and protective liner in the manufacturing of self-adhesive labels, adhesive tapes, graphic films, medical patches and wound dressings, composite prepreg materials, and any product that contains an adhesive surface which must remain protected until the moment of application. Without release paper, adhesive products cannot be manufactured, stored, transported, or dispensed in roll or sheet form — the adhesive would bond to anything it contacts.
Release paper works through the surface chemistry of cured silicone. The silicone release coating — typically a cross-linked polydimethylsiloxane (PDMS) polymer cured by platinum catalyst or thermal initiation — creates a surface with extremely low surface energy (approximately 20–24 mN/m). Pressure-sensitive adhesives have significantly higher surface energy (typically 30–45 mN/m), which means the adhesive has a much stronger affinity for the substrate it is intended to bond to (such as a label facestock or tape backing) than for the silicone-coated release liner. When the release paper is peeled away, the adhesive transfers completely to the higher-energy substrate and leaves no residue on the release liner. The force required to peel the adhesive from the release liner — called the release force or peel value — is controlled by the silicone formulation, coating weight, and curing conditions. Low release force (5–30g/inch) is specified for easy-peel applications like label dispensing. High release force (100–400g/inch) is specified for applications where the adhesive must remain firmly attached to the liner during high-speed converting, die-cutting, and matrix stripping operations.

Release paper uses a cured silicone coating for its non-stick properties, providing consistent, temperature-stable release performance over a wide range of conditions. Wax paper uses a paraffin wax coating which softens at low temperatures, transfers wax residue to adhesive surfaces, and provides inconsistent release force. For industrial adhesive applications, wax paper is never acceptable — silicone release paper is required for clean, residue-free separation.
Kangchuang offers release paper with release force values from 5g/inch (ultra-easy release for automatic label dispensing) to 400g/inch (tight release for high-speed die-cutting with matrix stripping). The release force is specified by the customer based on the adhesive type, converting equipment speed, and end-use application. Standard release force grades are available from stock; custom release force values require minimum order quantities.
We offer release paper on three base paper types: glassine (smooth, translucent, low-caliper — standard for label stock), super-calendered kraft (higher strength and tear resistance for tape and graphic film applications), and clay-coated kraft (very smooth, high hold-out for precision silicone coating — used for premium label and medical applications). The base paper type affects the release paper’s strength, transparency, surface smoothness, and dimensional stability.Can release paper be used for composite prepreg manufacturing?
Yes. Release paper is widely used in aerospace and industrial composite manufacturing as the carrier liner for prepreg (pre-impregnated composite fiber sheets). The silicone release coating allows clean separation of the release liner from the uncured resin surface during layup. For composite applications, we supply release paper with controlled release force, high temperature resistance, and consistent surface smoothness to ensure uniform resin distribution.
Yes. Double-side silicone release paper has silicone coating on both sides — typically with different release force values on each side (differential release). This is used for adhesive products that are stacked or wound with adhesive surfaces exposed on both sides, and for specific die-cutting applications where both surfaces of the liner must release cleanly.
