PVC shrink film is a type of packaging material that is used to wrap products for protection and branding purposes. It is made by extruding PVC resin and additives through a blown film process. The film is then heat shrunk onto the product using a heat gun or a heat tunnel. This process creates a tight and secure seal that protects the product from external elements like dust, moisture, and tampering.
