LDPE shrink films are a type of plastic packaging material made from low-density polyethylene, a polymer that is known for its flexibility and resilience. These films are used to wrap products and, when exposed to heat, they shrink tightly around the item, forming a protective, snug covering. The shrinkage process is triggered by applying heat to the film, causing the molecules in the polymer to contract and create a tight seal around the product. This provides a durable, protective layer that can guard against dirt, moisture, and physical damage.
