PET Film
Product Specification
PET film (Polyethylene Terephthalate film) is a high-performance thermoplastic polymer, belonging to the polyester family, widely utilized for its exceptional strength, clarity, and versatility. It is frequently referred to as BOPET (Biaxially Oriented Polyethylene Terephthalate) when stretched for added durability.
Key Properties
- High Strength & Durability: Known for excellent tensile strength and resistance to tears and punctures.
- Optical Clarity: Offers superior transparency, making it ideal for packaging and display screens.
- Thermal Stability: Maintains its physical properties over a wide temperature range, often up to 130°C (266°F) continuously.
- Barrier Properties: Provides strong resistance to moisture, gases, and aromas.
- Chemical Inertness: Resistant to oils, grease, and most acids.
Common Applications
- Flexible Packaging: Used for food packaging, such as coffee pouches, lidding films, and snack bags, due to its ability to protect against oxygen and moisture.
- Electronics: Serves as a base material for flexible printed circuits, membrane switches, and electrical insulation in motors.
- Industrial & Technical: Used in vacuum metalizing, solar control windows, and as technical films for industrial coatings.
- Imaging & Graphics: Employed in printing, photographic, and X-ray films, as well as protective overlays.
Manufacturing & Types
PET film is produced via extrusion and often biaxially oriented (stretched) to enhance its mechanical properties. It can be treated to be metallized, siliconized, or heat-sealable.

- BOPET: Stretched in both machine and transverse directions.
- Metallized PET: Coated with a thin metal layer (like aluminum) to boost barrier properties and decorative appeal.
- Soft Touch PET: Treated for a soft, matte tactile feel, often used for luxury packaging.
Sustainability
PET is one of the most widely recycled plastics. Recycled PET film (rPET) can be repurposed into containers, clothing fibers, and industrial products.
