Stretch Wrap Overview

Stretch Wrap Overview

Stretch Wrap- A highly stretchable plastic film usually made from linear low-density polyethylene (LLDPE) that is wrapped around items. The elastic recovery keeps the items tightly bound.

Stretch film is commonly used to wrap products on pallets and secure them to each other and the pallet. This often helps to reduce product loss, discourage load tampering, and reduce worker injury. We explain in further detail in our blog post What is stretch film used for. There are a variety of widths, thicknesses, and types of stretch film.

Below is a breakdown of the two most commonly used extrusion processes of stretch film. Extrusion is the manufacturing of stretch film and a variety of other flexible plastic products. Visit our blog for further details about the extrusion process.

Cast Stretch Wrap- Also called cast stretch wrap, is manufactured using a cast extrusion process. The Cast extrusion process is a continuous process by which a thermoplastic material is melted and extruded through a flat die onto a chill roll, where it is quenched and re-solidified. This process allows the Cast stretch film to have excellent clarity, require less force to stretch, increased tear resistance, unwind quietly from machines, and offer a superior cling. There are both machine grade and hand grade cast stretch film available.

Advantages of Cast Stretch Film- Generally less expensive than blown stretch film, due to reduced manufacturing costs. Increased clarity allows users to see wrapped products. Cast stretch wrap unwinds quietly compared to blown stretch wrap. Cast stretch film offers two-sided cling that allows the wrap to stay securely wrapped.

Stretch Film Information

What is Stretch Film?

Stretch film is a plastic film used to secure, bundle, and stabilize products. Stretch film is made from linear low-density polyethylene. When applying the film is to be pulled and stretched around products to obtain tight and secured product loads. Stretch film comes in a variety of widths, thicknesses, and colors.

Types of Stretch Film:
Hand Stretch Film
Most of our hand film comes with a standard 3" core that will fit most any hand dispensers. Choose everything from clear to colored and even anti-static stretch wrap film.

Machine Stretch Film
Our machine pallet stretch wrap is offered in true standard gauged film as well as pre-stretched and equivalent film. All of our machine films can run on stretch wrap machines with up to a 250% stretch.
