Polypropylene’s strong sustainability story
When it comes to the circular economy, polypropylene has a compelling story to tell.
For starters, strong demand exists for recycled PP in a variety of diverse end markets and everyday products. This helps to close the loop and means the material often ends up having a very productive second, or even third, life.
Additionally, PP requires significantly lower energy inputs than competitive materials during production of the granulate, and has high energy recovery values – all of which contribute to an overall lower carbon footprint.
The resin known as NX™ UltraClear PP – polypropylene clarified with Milliken’s Millad® NX™ 8000 – brings substantial added benefits. Clear, transparent packages thermoformed from NX™ UltraClear PP offer easy-seal/easy-peel, mono-material lidding, which removes the multimaterial challenges associated with recycling.
The lower density of NX™ UltraClear PP also means it is 18% lighter than PET. This can help to reduce shipping costs, and result in lower per-unit production costs, since tests have shown that 1 kg of NX™ UltraClear PP produced 70 clear, thermoformed trays, while the same amount of PET yielded just 57 trays.
