Mitsubishi Polyester Film, a subsidiary of Mitsubishi Plastics, has started a $20m upgrade at its polyester film making plant in Greer, South Carolina, US.

According to Mitsubishi, the project will increase the factory’s capacity for manufacturing polyester films, and will provide enhanced capability for new products.

The upgrade comes on top of a $10m project launched late in 2010 to rollout the reprocess sustainable liner programme. This recycling process makes PET pellets from the inline silicone-coated release films that are used as dispensing liners for labels placed on consumer goods, including beverage bottles and personal care products.

Mitsubishi said the company has invested more than $200m at its Greer facility over the past ten years.

The upgrade work to the Greer facility is expected to be completed in late 2012.
