How to Source Shrink Film from China

Quick answer

Source shrink film by locking polymer family (often PE or POF), gauge, shrink ratio, clarity, and whether you run a heat tunnel, heat gun, or shrink wrapper—not by buying the cheapest micron label. Shrink film is not stretch wrap; keep RFQs separate.

Where shrink film is used

Bundling multipacks, protecting printed cartons, and some retail multipacks needing tight skin presentation. Stretch film unitizes pallets without heat; shrink film needs controlled heat to contract. Mixing the two wastes sampling time.

Material families

POF is common for retail clarity and lower gauge multipacks; PE shrink appears on many industrial/bundling jobs. Ask for sealability, puncture, and odor notes for food-adjacent packs. Recycled content options exist—require documented % if you claim it.

Machine and process fit

State tunnel type/temperature window, L-bar or side-seal equipment, or manual heat-gun use. Film that seals cleanly on one machine may burn or under-shrink on another. Approve samples on your line.

Gauge, yield, and presentation

Balance clarity, stiffness, and cost. Over-gauging hides weak process settings; under-gauging causes dog-ears and tears. Define print/registration needs if using printed shrink sleeves vs plain bundling film—this guide focuses on bundling/wrap film, not full sleeve labeling systems.
