The 2026 Stretch Film Buyer’s Guide: Gauge, Resin, and Containment

Stretch film is bought by the gauge on the spec sheet, but it lives or dies by how it wraps a load. This guide breaks down what actually matters when you compare film suppliers in 2026, and how to pressure-test a quote before you sign it.

Gauge is a measurement, not a performance claim

Gauge measures thickness; it does not describe strength, yield, or containment. A modern high-performance 60-gauge can outperform commodity 80-gauge because the resin system and processing matter more than raw thickness. If your supplier is only quoting you on gauge, they are selling you commodity film.

Cast vs. blown film

Cast film is manufactured through a chilled roll process and typically offers high clarity, consistent thickness, and a quiet release from the roll. Blown film is manufactured on a blown bubble line and generally delivers higher tear resistance and better puncture performance. Most operations use both: blown for rough or heavy loads, cast for light or uniform pallets.

Pre-stretch is where money lives

Most machine wrappers are capable of 200 to 250 percent pre-stretch, but many run at 100 to 150 percent. Every 50 percent of unused pre-stretch is film you bought and did not use. If you have not had a stretch film containment audit in the last year, this is almost always the biggest savings lever.

Containment force is the only real metric

Containment force is the squeezing pressure the film applies to the load. It is measured in pounds of force and is the only number that predicts whether a pallet will survive transit. Strong containment numbers typically require matched film, matched pre-stretch, and matched wrap pattern. Every serious program should measure it.

Questions to ask every stretch film supplier

• Will you put your film on our wrapper and measure actual containment force?
• Is your quoted price delivered, or does freight get added later?
• What is the gauge-to-yield ratio on the film you are proposing?
• Can you match or beat our current spec on a dollars-per-pallet basis?
