Industrial stretch film is a highly stretchable plastic film used to secure and protect items during storage and shipping. It is most often used to bind boxes together on a pallet to stabilize the load, but it can also be used to bundle individual items. Made from linear low-density polyethylene (LLDPE), its elastic properties allow it to cling tightly to itself, preventing items from shifting or falling over.

Types of industrial stretch film

Industrial stretch film is available in many varieties, categorized by their application method and specific features.

By application method

1.Hand stretch film: This is sold in smaller, lighter rolls designed for manual application. It is commonly used for low-volume operations.

2.Machine stretch film: Intended for use with semi-automatic or automatic stretch-wrapping equipment, this type comes in larger, heavier rolls. It is used for high-volume applications and provides greater efficiency and superior load containment.

3.Pre-stretch film: This film is stretched close to its breaking point during manufacturing. This allows it to be applied with less effort, and because less film is needed for each load, it can lead to cost savings.

By manufacturing process

1.Cast film: Produced through a cast extrusion process, this film is clear, quiet to unwind, and generally less expensive. However, it offers less tear resistance and memory than blown film.

2.Blown film: Manufactured using a blown extrusion process, this film is more durable, with better tear resistance and memory to secure heavy or difficult loads. It is typically more expensive and noisier to apply.
