Toughness Polyester Film is a new packaging material developed by TOYOBO. It is compatible with PET and PA film properties. Due to its excellent flexibility and toughness it can dramatically reduce wrinkling and curling during packaging production. Compared with a conventional multi-layer film, the film using Toughness Polyester Film has the following advantages: 1) lower packaging costs, 2) better printability, 3) improved lamination without curling and 4) better bag-making. Toughness Polyester Film contributes to reduce waste and increase the productivity.
