Category: Bopp Heat Sealable Film
Heat sealable BOPP film production line
consists of casting sheet extrusion, biaxial orientation, after
treatment, rolling, cutting, and automatic control. It can produce BOPP
films of various specifications and stable dimensions, with good
mechanical and electrical performances, good heat resistance, cold
resistance and gastightness.
BOPP film heat-sealable on both sides, giving flexibility for lamination and packaging machines that need to seal from either face. Provides strong hot-tack, high transparency and stable performance across a range of thicknesses.
