Usage and principle of heat-shrinkable bag

Usage and principle of heat-shrinkable bag;

Heat shrinkable bag is a kind of multi-layer co-extruded PVC bag, which is sealed at one end and opened at the other. It is not much different from ordinary bags, but it has good characteristics.

Can shrink horizontally and vertically: the shrinkage rate is strong

Good cold resistance: it can be kept at -40℃ for a long time without brittle crack, which is suitable for cargo transportation or storage.

High transparency: the heat-shrinkable bag is made of a brand-new material, without adding impurities such as recycled materials, so it has high transparency, and packaging on the product can improve the packaging texture of the product.

High strength: tensile property, no delamination, good flexibility and strong heat sealing.

Wide application range
