Co-polyester Film Products
Packstar's co-polyester films are sold under the trademarked name BONPET. Like PVC, BONPET is a transverse, monoaxially oriented film, but it can be used on a much wider range of container shapes and sizes than PVC. The unique BONPET manufacturing process was developed through 10 years of research and experimentation, resulting in a co-polyester film product that combines superior shrinkage with excellent printability.

Currently, Packstar offers two grades of BONPET film. New and improved films offering enhanced process printability, increased machine direction control, and other specialized properties are currently in development and will be available soon.
  • BONPET 5A PETG Film is Bonset's popular co-polyester alternative to PVC film. PETG offers excellent printability and a much higher rate of transverse directional shrinkage (>75% @ 100 C 30 seconds by water) than Bonset's PVC film. For better processing, PETG film is treated on one side with an anti-static coating.
  • BONPET UB PETG With UV Film has ultraviolet brightener added to it to make evidence of tampering easily detectable under a black light. Due to the UV brightener property, this film is best used in minimal print applications.
