PVC Heat Shrink Sleeve is a type of shrinkable packaging material made from polyvinyl chloride (PVC). It is used to wrap products and create a secure, tight-fitting layer that protects against moisture, dust, and other external factors. PVC Heat Shrink Sleeve is designed to shrink uniformly in all directions when heat is applied, conforming to the shape of the product and creating a tamper-proof seal. It is widely used in the packaging industry for products such as bottles, cans, jars, and other containers.
