Polyester Digital Weighing Scales Graphic Overlays
Polyester film is tougher, more durable, and more expensive than Polycarbonate and PVC films.
Similar to polycarbonate in material characteristics, polyester Weighing Machine Stickers offer superior fatigue resistance and are the preferred choice in applications where use requires constant flexing. Greater tensile strength than polycarbonate. Custom screen printed polyester weighing scale cabinet sticker are dimensional stability, excellent heat resistance, abrasions and scratch resistance, resistance to chemical, suitable for outdoor use. Recommended for digital weighing scales membrane switches, especially when embossing is involved. Available in matte, selective textured, clear/gloss, clear LCD windows, selective adhesive, embossed finishes.
