Lidding Film Buyer's Guide
Lidding film is the printed, heat-sealable top web that closes a pre-formed tray or cup. An easy-peel lidding film is engineered to peel open cleanly by hand without tearing, while a weld-seal (lock) film bonds permanently for tamper evidence. The right lidding film is chosen by the tray material it must seal to (PP, PET/APET, PS, PVC or paper), the barrier your product needs and whether you want a peel or a weld seal.
Clean peel. Reliable seal. Right barrier.
Lidding film is what makes a tray or cup a sealed pack. It has to do three jobs at once: seal reliably to the tray on a tray-sealing or cup-filling line, protect the product with the right barrier, and open the way the consumer expects — a clean peel for ready meals and dairy, a permanent weld where tamper evidence matters. Get the sealant layer wrong and you see leakers, stringing or lids that won't open; get the barrier wrong and shelf life falls short.
This guide covers the two seal types, how to match the sealant to your tray, the barrier options and the practical specs to confirm before you order. Antilia Tec Pack supplies easy-peel and high-performance lidding films on BARRIXA™ barrier structures.
An easy-peel lidding film is designed to separate cleanly from the tray flange when a consumer pulls the corner — no tearing, no residue. It suits ready meals, dairy, fresh produce and anything opened by hand. A weld (lock) seal bonds permanently and is cut or punctured to open; it is used where a tamper-evident, non-reclose seal is preferred. Many films are tunable between the two by adjusting the sealant and seal temperature.
Lidding film only works if its sealant layer is chosen for the tray material it meets. The common pairings are:
| Tray material | Seal approach | Typical use |
|---|---|---|
| PP (polypropylene) | Peel or weld to PP | Ready meals, hot-fill, retort trays |
| PET / APET / CPET | Peel or weld to PET | Chilled meals, bakery, produce |
| PS (polystyrene) | Peel to PS | Dairy, desserts, cups |
| PVC | Peel to PVC | Fresh produce trays |
| Paper / board | Heat-seal coating | Sustainable fibre trays |
A universal-peel sealant can seal to several of these, which simplifies stocking when you run mixed trays. Confirm the exact tray resin with your supplier before specifying.
Beyond the seal, a lidding film carries the barrier. For MAP (modified-atmosphere) meals and oxygen-sensitive foods, a high-barrier lidding film holds the gas flush and extends shelf life — match it to a BARRIXA™ tier the way you would any barrier pack. An anti-fog treatment keeps the film clear over chilled or warm product so the food stays visible. Lidding film also prints beautifully by rotogravure, so the lid doubles as your brand face and ingredient panel.

Easy-peel lidding film is a heat-sealable top film for trays and cups that is engineered to peel open cleanly by hand without tearing the film or leaving residue on the tray flange. It is widely used for ready meals, dairy, desserts and fresh produce.
A peel seal is designed to separate cleanly from the tray when pulled, for easy opening. A weld (lock) seal bonds permanently and is cut or punctured to open, which gives tamper evidence. Many lidding films can be tuned between the two by adjusting the sealant and seal temperature.
Start with the tray resin — PP, PET/APET, PS, PVC or paper — because it sets the sealant layer. Then choose peel or weld, match a barrier tier to your shelf-life target, and add anti-fog, window or print as needed. A universal-peel sealant can seal to several tray types.
