Coveris launched PolyFlex Thermoform, a nylon-free, recycle-ready thermoform pack now used on three Al'Fez flatbreads made by Signature Flatbreads in UK and EU retail (reported Sept. 30, 2026). Coveris says it holds a 12-week shelf life and runs on existing packing lines.

Coveris announced Sept. 30, 2026, that its PolyFlex Thermoform material has made its bakery debut on three Al'Fez flatbreads produced by UK baker Signature Flatbreads, including flame-baked Turkish-style minis, sold at UK and EU retail. The pack drops the nylon found in most thermoformed food laminates while keeping a high oxygen barrier.
The tray is formed from a single-polymer polyethylene web and sealed with a PE/PP lid. According to Coveris, trials in its Winsford and Gainsborough labs confirmed 12 weeks of shelf life, and the pack matched or beat the previous one on puncture and heat resistance and clarity while running on the same packing equipment. IN Food (Oct. 2) cautioned that packers still need to requalify forming temperatures, seal settings and web handling, and that rejects, downtime and waste in daily runs will be the real test.
UK shoppers can return the pack at in-store soft-plastics bins now; Coveris tied the launch to UK EPR fees, Simpler Recycling's 2030 kerbside film collection and the EU's packaging regulation (PPWR). The company has used similar nylon-free polyolefin films in block cheese. For U.S. tortilla plants, which mostly use poly bags, the relevance is to premium and thermoformed flatbread SKUs.
