PET Film Converting

For more than 45 years DUNMORE has stood for the highest quality in coating, laminating, and metallizing of PET film in a variety of thicknesses from .25 mil to 10 mil. DUNMORE’s coating capabilities and laminating capabilities can process polyester film up to 98" (2.5m) wide and can metalize PET film up to 80" (2m) wide.

The mechanical properties of polyester film and the availability of PET film that can be engineered to meet your specific needs makes it the premier film choice for a variety of industries. DUNMORE’s converted PET films and DuPont Teijin Films™ Mylar® are used for the following applications:

Polyester Film (PET)

PET film or PolyEthylene Terephthalate film is a thermoplastic polymer commonly referred to as Mylar® polyester film. Like most thermoplastics, PET films can be biaxially oriented (BOPET film), bubble extruded, and co-extruded (co-extruded PET film). Polyester film is one of the most common substrates used in the converting industry because of its balance of properties in relation to other thermoplastic polymers. Also, the processing tolerances of Mylar™ PET film makes it the ideal choice for vacuum metalizing, coating and laminating. PET Film is comparable or better than other thermoplastics in the following categories:

  • Specific gravity
  • Elongation
  • Melting point
  • Tensile strength
  • Tear strength
  • Oxygen permeability
  • Water vapor transmission rate
  • Insulation breakdown
  • Dielectric constant
  • Service temperature range
  • Dimensional stability
