The Science Behind Stretch Film

Material Composition of Stretch Films

Stretch films are primarily made from linear low-density polyethylene (LLDPE), a type of plastic that is known for its flexibility, resilience, and strength. The plastic is extruded or forced through a circular die to form a thin, continuous film. Additives are often included in the material composition to enhance certain properties such as clarity, tear resistance, and stretch ability.

The Manufacturing Process of Stretch Films

The manufacturing process of stretch films involves extrusion, where the LLDPE is melted and forced through a circular die to form a thin film. The film is then quickly cooled to solidify it. This is followed by the stretching process, where the film is heated and stretched to increase its elasticity and strength. The stretched film is then cooled and wound onto rolls.

How Stretch Films Works to Secure Loads

The science behind stretch films lies in its ability to recover its original size after being stretched. When the film is applied to a load, it is stretched around it. After application, the film tries to return to its original size, creating a force that “holds” the load together. This elastic recovery of the film keeps the items tightly bound, preventing movement during transport.
