PET Film
Polyester Film (PET)
PET or polyethylene terephthalate film is a thermoplastic polymer commonly referred to as polyester film. Like most thermoplastics, PET films can be biaxially oriented or bubble extruded. 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. PET Film is comparable or better then 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
The mechanical properties of polyester film make it a choice substrate for a variety of processing technologies, such as vacuum metalizing, coating and laminating. Additionally, polyester film is available in many variations, engineered for specific applications, this combined with the processing tolerance of PET films makes it a good substrate for a variety of applications. PET film can be used in the following industries:
- Antimicrobial films
- Printable films / Labeling / Label Facestocks
- Insulation films
- Packaging films
- Photovoltaic backsheets
- Security films / Tamper Evident Films
- Surface Protection Films / Hardcoats / Protective Films
