Developed with Waste & Resources Action Programme (WRAP) funding, “Integrity Seal” has been perfected by consultancy International Food Partners (IFP), working with UK flexible film sealing system specialist Ceetak, Tilmanstone Salads and M&S. The technology uses heat to melt the film to make a welded seal on the pack ends just 1mm wide rather than using the “traditional” method of crimping, which the project partners say results in a much wider seal. Trials have shown Integrity Seal produces a “superior seal” compared with crimping, in turn increasing shelf-life of some salads from 5-8 days. WRAP is now producing a full technical report and case study showing how the technology can be applied,
Project manager Andrew Parry says: “This new technology could be applied across a wide range of product packs, from salad and snack bags to cosmetics and DIY products. It reduces the amount of material used for each bag, and can keep product fresher for longer, so has the potential to divert a substantial amount of packaging material and food waste from landfill sites.”
