PET Polyester Self Adhesive Window Film High Temp Resistant For Packaging / Printing
High temperature resistant PET polyester film , BOPET film for packaging and printing
Product Description:
The surface of the film is smooth and smooth, free of defects such as creases, tears, particles, bubbles, pinholes, etc. The product has the advantages of excellent mechanical properties, small thickness tolerance, stable chemical properties, high heating temperature, low heat shrinkage and good flexibility. It is mainly used for food packaging materials. The surface of the material has high adsorption, and the printing ink is not easy to fall and the composite is tight
