50μm Translucent Blue PET Release Coating Polyester Film
50 μm blue PET silicone coated release film designed for tapes, labels, packaging, and various industrial applications. This light blue translucent polyester film offers exceptional tensile strength, flexibility, and reliable release characteristics.
Key Applications
- Industrial Tapes: Provides protective backing for double-sided tapes, cloth tapes, and foam tapes, ensuring adhesive surfaces remain protected during transportation and storage.
- Graphic Overlays: Serves as temporary protective backing for graphic overlays, safeguarding both adhesive sides and printed surfaces during installation.
- Adhesive Labels: Used in manufacturing self-adhesive and pressure-sensitive labels to maintain adhesive strength and substrate adhesion.
- Flexographic Printing: Functions as a base layer for printing plates, protecting them during manufacturing, printing, and transportation.
- Packaging: Provides temporary protective backing for adhesive surfaces of wraps, bags, and labels, ensuring product integrity throughout distribution.
