Plastic is necessary for packing quilted natural insulation. At present there is no alternative material available that provides adequate protection for our products during transit and storage. We are constantly reviewing this position. In our case, not only does plastic packaging protect the product, it also enables our supplier to compress the insulation greatly reducing packaging waste and carbon miles from factory gate to our warehouse, to you the customer. Our Thermafleece suppliers use recycle code 4 LDPE for all of their packaging. Most of the insulation is compress packed in order to minimise packaging. Compress packing also enables them to reduce the thickness of packaging. The packaging weight per sqm of 100mm Thermafleece CosyWool is 22g per sqm their packaging waste is around a quarter of that from alternative brands of natural insulation.
