Shrink film gauge — the thickness of the film — is one of the most overlooked specs in packaging, but it has a direct impact on how your product looks and holds up in transit. Too thin and you risk tears; too thick and you're overspending on material and getting a looser, less polished shrink. Here's how to land on the right gauge.
Start With Your Product's Weight and Edges
Heavier products and items with sharp corners or edges need a thicker, more puncture-resistant gauge. Lighter, smoother retail items can typically use a lighter gauge and still get a clean, tight shrink without the added material cost.
Consider How the Product Will Be Handled
A product that's only handled once at checkout has different needs than one going through a shipping and fulfillment chain with multiple touchpoints. The more handling between packaging and the end customer, the more puncture resistance you should build in.
Factor In Your Tunnel and Sealer
Not every machine performs the same way with every gauge. Check your tunnel's temperature range and your sealer's capabilities before settling on a film — a mismatch here is one of the most common causes of inconsistent shrinking. If you're unsure what your equipment can handle, our film selection guide walks through compatibility.
RS vs. X Shrink Film
Our RS Shrink Film is built for consistent, everyday packaging performance. Our X Shrink Film is the premium option, designed for stronger shrink performance and higher durability when you need extra protection. Both come in a range of gauges to match different product types.
Still Not Sure?
Tell us your product type, weight, and how you're shrinking — tunnel temperature and line speed — and we'll recommend the right gauge so you're not guessing. Browse our full shrink film lineup or contact our team directly.
