Lidding film is one of those materials that seems simple until it doesn't seal right, doesn't peel cleanly, or doesn't hold up in cold storage. Getting the seal right depends on matching film to tray material, product, and how the package will be handled. Here's how to think through it.
What Lidding Film Actually Needs to Do
Lidding film has to form a reliable seal against a tray while also meeting whatever else the product demands — peelability, clarity, barrier protection, or freezer performance. No single film does all of these equally well, which is why matching film to application matters more than picking the most premium option available.
Peelable vs. Non-Peelable
Peelable lidding film is designed to separate cleanly from the tray without tearing or leaving residue — important for ready-to-eat food packaging where the end customer opens it by hand. Non-peelable film creates a stronger, more permanent seal, often used when the package will be cut open rather than peeled.
Matching Film to Tray Material
Lidding film needs to be compatible with the tray material it's sealing to — PET, PP, and PLA trays all seal differently, and a mismatch can mean a weak seal even when everything else is right. Our lidding film is built to perform reliably across common tray materials used in food and retail packaging.
Cold Storage and Barrier Needs
If your product is going into refrigeration or freezer storage, seal integrity under temperature stress becomes a bigger factor than it would be for shelf-stable products. Flag this upfront when choosing a film — it changes which options actually hold up.
