PROJET PET

The food-packaging market has clearly evolved towards reducing the thickness of packaging, eliminating chlorine compounds and lessening environmental impact. The development of new biodegradable materials requires quick supply at competitive prices, so SP GROUP worked on finding an alternative to mono-material packaging.

Polyethylene Terephthalate (PET or polyester) is a versatile thermoplastic polymer that can be recovered and reused today, meaning it can further reduce the problem of waste accumulation. SP GROUP focused on researching new types of modified PET and developed new structures that are suitable for hot filling, pasteurisation and microwave use, by modifying the composition of the materials.

The functionality of the material was fully optimised, and the carbon footprint and environmental impact of the packaging was studied and improved.
