    LDPE (Low-Density Polyethylene) shrink film shrinks when heated due to its molecular structure. LDPE contains long chains of polymer molecules with random branching, allowing for flexibility and stretchability. When exposed to heat, these molecules gain energy, causing them to vibrate and move more freely. As a result, the film contracts and conforms to the shape of the object being wrapped. The heat activates the film’s memory, causing it to return to its original, more compact state. Shrink wrap manufacturers in Ahmedabad utilize this property by carefully controlling the heating process during production to ensure consistent and reliable shrinkage. By understanding the behavior of LDPE at different temperatures, manufacturers can produce shrink films tailored to specific applications, providing efficient packaging solutions for various industries.
