Sumitomo (SHI) Demag - Moulding specialist scores pudding PET pot first

18 September 2015

Following the purchase of a fully-electric IntElect 160 Smart machine from Sumitomo (SHI) Demag, injection moulding specialist Patterson & Rothwell has become the first company to produce recyclable thin wall PET premium dessert pots for the food industry. 

For many years, pots for desserts, such as yoghurts and mousses, have been injection moulded from general purpose polystyrene (GPPS). The downside to them is that they crack easily and cannot be recycled. Patterson & Rothwell knew that if it could develop a pot made from more hard-wearing and eco-friendly PET, it would be offering something unique in the marketplace that would ignite the interest of the major retailers. 

After two years of focused R&D, the company has accomplished its goal - stable production of recyclable PET pots that are 0.4mm thinner than GPPS dessert pots. However, the odds were stacked against a successful outcome.
