LDPE (Low-Density Polyethylene) shrink films have become an essential component in the packaging industry, offering a blend of flexibility, strength, and excellent barrier properties. Known for their ability to conform tightly around products when heat is applied, LDPE shrink film is widely used for packaging a variety of goods. This article delves into the features, benefits, and applications of LDPE shrink films, with a focus on their significance in the Indian market.
What is LDPE Shrink Film?
Polyethylene shrink film is a type of thermoplastic film made from low-density polyethylene, which, when heated, shrinks tightly over the products it encases. This shrinkage creates a tight seal that protects the contents from dust, moisture, and other environmental factors. LDPE shrink films are known for their clarity and gloss, making them visually appealing for retail packaging.
