4 Pcs Silicone Food Covers Pack Key Info manufacture
Developed in the 1940’s Silicone is a relatively new material in the kitchen world. Silicone comes from silicon which is one of the most abundant materials on Earth (28% of the earth’s crust, so there is a lot of it!), it is used as a new plastic kitchen alternative for many items. Silicone is a polymer made up of materials like sand combined with oxygen, carbon and hydrogen. Once produced the silicone material is cut into appropriate pieces for the covers and placed into the cover moulds at high heat. The moulds are compressed so the material can take the lid shape, then removed and left to dry.
Unlike plastic silicone is not made from petroleum-based chemicals and will not release microplastics into out oceans.
Silicone is completely BPA Free and will not melt till easily over 600 degrees and is freezer proof.
Silicone cannot be seen as being the answer to all of our problems; The material will not biodegrade and has a very large energy consumption manufacture process involving industrial blast furnaces. However, plastic materials are part of our everyday life due to their ease of moulding manufacturing and manipulations, making the use of silicone much better for our environment rather than using traditional plastics.
