How to Select Stretch Wrap

June 20, 2019

Shrink wrap is a poly plastic product that is applied with the use of a heat gun that heat shrinks the film so that it conforms securely around the product to which it is applied. It's most common application is for storage and protection from the elements. In short, shrink wrap is used to cover and protect product.
Stretch wrap is a poly plastic product that is used most commonly to wrap pallets of boxes or other product. It is stretchy with a strong elastic property and usually has a two-sided cling to is sticks to itself. It does not need a heat gun or any other special equipment to be successfully applied. In short, stretch wrap is used to contain product and hold them together.

What is “gauge” and how do I know what gauge I need?

Gauge is the most common measure of the thickness of stretch film (sometimes also measured in microns)
100 gauge = 25.4 microns = .0254mm = .001in
The higher the number, the thicker the film (100ga > 80ga > 60ga, etc)
80 gauge is the most common film, the “average” or “standard”
Heavier gauge films are typically required for:
Heavy loads, such as fasteners, machine parts, bags of mortar or mulch, etc.
Uneven loads with more corners and angles (also known as B- or C-loads)

Greater puncture potential

Lighter gauge films are typically required for:

Lighter loads, such as foam products, or light food products (snack foods like chips, etc)

Even, square loads (also known as A-loads)
Little to no puncture potential
Film is typically available in gauges ranging from 40ga - 150ga
Ultimately, the thickness needed is subjective. Samples film, when available, is ideal to determine what works best for your needs.
