PETUK are the acknowledged leaders in batch Solid State Polymerization (SSP) offering a toll processing service to the plastics industry.

– The SSP process changes the crystallinity and molecular weight of semi-crystalline thermoplastics, such as PET and its derivatives.

– This results in improved processing and physical properties of the customer’s finished products.

– PETUK is a unique and highly efficient organization operating 24/7 processing over 15,000 tons per year.

– More and more materials are being delivered in bulk bags.

As part of a major plant upgrade, PETUK required a new bulk bag filler. The exact weight of processed material in each bag must be confirmed so they contacted Avery Weigh-Tronix, the UK’s leading weighing company and the supplier of the other weighing equipment onsite. Avery Weigh-Tronix don’t make bulk bag filler but they recommended Spiroflow.
