American shrink film buyers ask sharper questions than most — because their lines run faster and their audits go deeper. LDPE shrink film in the US lives in beverage multipacking, food bundling and industrial packaging, and the qualification conversation is always the same three-part test: food-contact status, film numbers, and the duty math as it stands in 2026. This checklist is how our US converter and distributor accounts run that test on us — and how you should run it on any supplier.
Food contact: 21 CFR 177.1520, stated plainly
Beverage multipacks and food bundling put the film in indirect food contact territory, and the governing rule is FDA 21 CFR 177.1520 for olefin polymers. Our multipack grades run compliant resins with declarations issued per shipment — and we state the use case plainly: indirect contact for transit multipacks, not direct food packaging. That distinction protects you in a customer audit; a supplier who blurs it is the one who fails you later. The beverage application is covered in our beverage transit packaging guide, and the grade differences in our bundle and wrapper grades guide.
Film tests that survive a line trial
The documentary set: tensile and elongation to ASTM D882, tear resistance to ASTM D1922 — batch certificates with every container. The practical set: shrink curve consistency roll to roll (tunnel settings must not chase ghosts between rolls), hot-tack on the seal bar, flat unwind on the rollers, and gauge verification at five points across the web. US converters validate film on their own tunnel before committing — air-shipped trial rolls from the production family, a full-shift run, then the container order. That trial discipline is standard on our side; a supplier who resists it is telling you something.
Entry compliance: the 2026 stack
LDPE film classifies under HTS 3920.10 with a base general duty around 4.2%. Since July 2026, the Section 301 additional action applies to Indian-origin goods at roughly 10% on top — so quote landed cost with 14-15% duty-related overhead plus MPF and HMF until your broker confirms the live Chapter 99 line. ISF 10+2 filings precede loading; our document set (invoice, packing list, mill certificate, resin declaration, test certificates) matches broker and audit expectations. East Coast entries through NY-NJ, Savannah or Houston run 28-35 days ocean from Mundra; LA/Long Beach serves the West. Production 7-10 days; six to eight weeks PO to warehouse door total depending on coast.
Roll specs sit on our LDPE shrink film product page; the sibling pallet-wrap product is on our stretch film page.
Frequently Asked Questions
Which shrink film SKUs need FDA documentation?
Any film positioned for beverage or food bundling — indirect contact. We run 21 CFR 177.1520 compliant resins on those grades and issue declarations per shipment.
What does the duty stack total in 2026?
Base around 4.2% on HTS 3920.10, MPF and HMF fees, plus roughly 10% Section 301 additional duty on Indian-origin goods since July 2026. Confirm the live rate with your broker before quoting landed cost.
What should a tunnel validation include?
Air-shipped trial rolls from the production family, a full-shift run checking shrink curve, hot-tack, seal integrity and film breakage count — then the container order at the validated spec.
What documents ship with each container?
Commercial invoice, packing list, bill of lading, mill certificate, resin/food-contact declaration and ASTM D882/D1922 batch certificates — the complete set for broker filing and customer audits.
