PET Fluorine Release Film

Product overview

PET fluorine release film uses dimensionally stable PET polyester as the base and a uniform fluorinated release layer on the surface. High clarity, smoothness, consistent coating and low particle levels combine with useful heat resistance and low thermal shrinkage. It serves as a carrier and release material in die cutting, lamination, printing and adhesive converting. Thickness, width, roll length and release force can be selected for silicone adhesives, high-tack systems and special peel requirements.

Product features

• High-transparency, flat PET base permits visual inspection and maintains processing dimensions.
• Uniform fluorinated release coating with a clean, low-particle surface supports consistent release.
• Useful heat resistance and low thermal shrinkage reduce deformation during heated lamination and processing.
• Provides reliable release from silicone pressure-sensitive adhesives and selected high-tack adhesive systems.
• Can be sheet-cut, slit into narrow rolls or supplied as master rolls with custom thickness, width, length and release force.
• Suitable for printing, die cutting, lamination and protective-film processing as a carrier and separation layer.

Applications

• Release liner for silicone adhesive tapes, silicone protective films and high-tack adhesive products.
• Carrier and separation film in precision die cutting, waste stripping, transfer and electronic-material conversion.
• Coating and lamination of screen protectors, optical films and other surface-protection products.
• Printing, laminating and tape production requiring a smooth, transparent release surface.

Procurement notes

Provide PET thickness, width, roll length, color, one- or two-sided release, release-force range, adhesive type, temperature, quantity and packaging. Silicone, acrylic and different coat weights require different release forces; provide an adhesive sample or current material details. Test release stability, thermal shrinkage, cleanliness and die-cut compatibility before volume ordering.
