About Lidding Films

Sealing Trays Reliably at Speed

Lidding film seals trays and containers, protecting contents from contamination and extending shelf life. When your tray sealer runs thousands of packs per shift, consistent film quality matters. Seal failures mean wasted product, customer complaints, and production disruption.

Tested on Proseal, Built for Production

If you’re running a tray sealing line, you know the difference between film that works and film that causes problems. Seals that don’t hold. Peel that shreds instead of lifting cleanly. Film that tracks inconsistently and needs constant adjustment. These aren’t minor inconveniences - they’re production delays, wasted product, and frustrated operators.

Our tray lidding films have been tested on Proseal heat seal equipment and perform reliably on Multivac, Ulma, and other leading tray sealers. We supply ready meal manufacturers, chilled food producers, and contract packers who run thousands of packs per shift and need rollstock that performs consistently from the first tray to the last.

We’re a family-owned UK converter with four decades of experience in flexible packaging. When you call us, you speak to people who understand tray sealing - not a call centre working through a script, but colleagues who can discuss seal temperatures, material compatibility, and troubleshooting without putting you on hold.

Ready Meals, Chilled Foods, and Beyond

PET lidding film is where we do most of our work. It seals reliably to APET, CPET, and rPET trays, peels cleanly without shredding or leaving residue on the rim, and maintains integrity through production, chilled distribution, and retail display. For ovenable and microwave safe applications, PET handles the journey from chiller to oven without the consumer needing to repackage.

For products like hummus, dips, yogurt, prepared salads, and deli items, presentation matters as much as protection. Your customers make purchasing decisions in seconds, and they’re not picking up a tray they can’t see into. Anti-fog treatments keep your products visible in chilled cabinets - crisp and appetising rather than hidden behind condensation. It’s a small detail that makes a real difference to how products sell.

For meat, poultry, and seafood applications where shelf life is critical, we supply high barrier lidding films with EVOH layers for MAP packaging. These maintain the modified atmosphere that extends shelf life, keeping products fresher for longer throughout the supply chain.

We also supply peelable lidding film for PP, PE, aluminium, and paperboard trays. Peel seal for consumer-friendly opening, weld seal where tamper evidence or cost is the priority. If you’re not sure what suits your application, we can talk you through it.

Recyclability That Stands Up to Scrutiny

Recyclability claims are everywhere, but there’s a difference between technically recyclable and actually recycled. PET lidding film on a PET tray creates a mono-material pack that qualifies for OPRL recycling - collected at kerbside, processed through existing infrastructure, turned into new materials. The kind of recyclable your customers can act on without a research project.

For customers pushing further, we offer food grade films with 30% post-consumer recycled content. We can also help with gauge optimisation - finding the minimum material weight that still delivers reliable seals. Sometimes using less material is the most meaningful sustainability improvement you can make.

UK Supply You Can Plan Around

We convert here in the UK, which means lead times of 3-4 weeks rather than months. No containers stuck at port, no customs complications, no supply chain mysteries where nobody can tell you where your order is.

When your tray sealer stops because film hasn’t arrived, you lose production time you can’t recover. We’ve been supplying food manufacturers for four decades, and we’ve learned that reliability matters more than almost anything else. Our customers stay with us because we deliver what we promise, when we promise it.
