Marks and Spencer’s recently asked us to supply 4 corner PET lids for a range of Valentines and Mother’s Day Confectionery Gift Packs. This product came with a particular problem. The special decoration on the chocolates meant they were prone to discoloration if exposed to UV light.
By working closely with our material suppliers, sheets of re-cycled PET with an in-built UV absorber were produced on very tight lead-times to a bespoke size. Prohibiting product discoloration helps ensure all the items are fit for purchase, so the possibility of increased food waste is avoided
The UV absorber was added to the core layer of a co-extruded film to ensure that the surface layers of the film were free from potentially migrating substances. Tests showed that the film filtered out nearly 100% of the incoming UV light.
The lids were produced on equipment designed and built by Staeger, and are welded at the corners, which avoids taint and odour issues as no adhesive are in the process.
The re-cycled PET is made from a minimum of 50% post consumer waste.
