BOPET film (biaxially oriented Polyester films) featurines good thermal stability and tenacity; low air and water permeability; applicable to vacuum aluminum plating, compound package, cooking bag manufacture, etc. Featuring : Having the good adhesion with ink and coating, can be used for multi-color printings with good flatness. Is mainly used in heat-sealing bags of frozen food, industrial products and cosmetics packaging. BOPET film including BOPP packing film, BOPET lamination film, BOPET insulation film, BOPET sheets, BOPET capacitor film, BOPET thermal transfer film,metallized BOPET film and so on. Specification:
Polyester film is wound around paper shaft with an internal diameter of 76.2mm-152.4mm and covered with polyethylene film; each coil is supported by damper and put in carton; medium and large package needs wooden mount. Customer's own requirement is available for us such as printed OEM logos and private label or particular size and package style.
