Double side PE coated silicone (PEK) release paper is made by first coating both sides of base paper with PE (such as LDPE, HDPE, MDPE or PP), and then applying single-sided or double-sided organic silicone—either solvent or solvent-free—onto the PE surface. The PE layer provides excellent barrier properties and smoothness, while the silicone layer offers controlled release performance. The product features good stiffness, high surface smoothness and high impermeability, making it suitable for various pressure-sensitive adhesive applications.
Aperçu du produit
This release paper is designed for self-adhesive labels, double-sided tapes, foam tapes, rubber sheets and other industrial laminates that require strong backing support and consistent release behavior. The PE coating protects the base paper from moisture and penetration by adhesives or chemicals, while maintaining dimensional stability during coating, drying and die-cutting.
Principales caractéristiques et avantages
- High stiffness: double PE coating and selected base paper provide good rigidity for stable web handling and converting.
- Excellent surface smoothness: smooth PE surface and uniform silicone coating ensure clean release and high-quality adhesive surfaces.
- High impermeability: effective barrier against moisture, oils and adhesive penetration, improving product shelf life.
- Flexible silicone options: single- or double-sided, solvent or solvent-free silicone systems available according to process needs.
- Customizable release force: release levels can be tuned from ultra-light to ultra-heavy to match different adhesive types.
- Imprimable : surface can be supplied with simple one-color printing for logos, grids or traceability information.
Applications typiques
- Label stock: release liner for paper and filmic pressure-sensitive labels used in logistics, food, pharmaceutical and industrial sectors.
- Double-sided & foam tapes: backing liner for tissue tapes, PET tapes and PE/PU/IXPE foam tapes.
- Composites industriels : release paper for rubber sheets, construction membranes, gasket materials and other coated products.
- Electronics & die-cut parts: carrier liner for precision die-cut adhesive components and protective films.
