Applications

Industrial Tape Manufacturing - Primary use in technical tapes, including butyl tape release film for roof and façade sealing, insulating and transfer tapes for construction applications, ridge tapes for ventilation and chimney flashing, and polyurethane/bitumen-based tapes for waterproofing systems. The embossed film serves as a protective liner, shielding adhesive layers from contamination and moisture while allowing smooth peeling without stretching or tearing.
Construction and Roofing - Ideal as a separating and protective layer in torch-on roofing membranes, bitumen shingles, roofing and sealing tapes, and repair components for roofs and foundations. Performs exceptionally in challenging environments due to resistance to tar, moisture, and weather conditions.
Technical and Automotive Industries - Used as a spacer or separator during assembly, protective film for delicate or painted surfaces, and carrier layer for laminates or self-adhesive components in vehicles.
