LDPE shrink films are a type of plastic film made from low-density polyethylene (LDPE). This material is known for its flexibility, durability, and excellent shrinkage properties. When heat is applied to LDPE shrink films, they shrink tightly around the product, creating a secure and protective covering. These films are often used for wrapping products and providing tamper-evident seals, ensuring that goods are protected during transportation and handling.
