How much is POF shrink film, PVC shrink film, PET shrink film, and shrinkage rate?

PVC heat shrinkable film: good transparency, printable, ?K can produce various tube, sheet, double-folded films of different sizes; easy to process into various shapes; low shrinkage temperature, 65℃; shrinkage ratio, horizontal: ≥45 %, vertical 0-25%, thickness 0.015-0.08mm; poor flexibility, not suitable for heavy packaging. POF heat shrinkable film: good transparency, good flexibility, and degradable; initial shrinkage temperature 100-150℃, shrinkage ratio, both vertical and horizontal directions are greater than 50%, thickness 0.012-0.04, not suitable for packaging heavy objects and long-term storage. PE heat-shrinkable film: good flexibility, high tensile force, opaque, suitable for group packaging and heavy packaging; initial shrinkage temperature is 180℃, shrinkage ratio is 0%-50% in horizontal direction, 50%-85% in vertical direction, and thickness is 0.03~ 0.15MM. It is not suitable to pack items that are not resistant to high temperatures.
