Polyester Films

Polyesters are made from chemical substances found mainly in petroleum and are manufactured in fibers, films, and plastics.

The excellent combination of optical, physical, mechanical, thermal and chemical properties of the polyester films is driving the growth of the specialty films market. Superior dielectric properties make it the preferred film for use in larger capacitors and also support its use in wire and cable insulation and electric assembly.

Features

• Good oxygen barrier properties ensure that polyester films find demand in the areas of flexible packaging and lamination.
• Polyester film features superior performance in printing, metalizing and cold seal applications.
• The film shows excellent scuff resistance, machinability and temperature characteristics.
• The adhesive can be clear or pigmented for ease of identification.
  

Types

• Solar Films- Are thin metallized polyester film that use an adhesive backing to attach the film to the inside surface of existing windows. The performance advantages of films include solar heat reduction, glare reduction, UV reduction, increased shatter resistance and some improvement in insulation value.
• Oriented Polyester Films- Are rigid plastics that are strong, durable, dimensionally stable, and have anti-curl properties. They are suitable for graphics, packaging, electrical and industrial applications. Available in sheets and rolls.

Applications: Polyester Films and Packaging
Polyester film used in many applications like high quality packaging, video tape, professional photographic printing, floppy disks, X-ray film etc. Polyester films have broad applications in the electronic, industrial, packaging and magnetic recording materials fields. They are used for packing milk and dairy products, and many synthetic washing-up liquids. They have high mechanical properties, attractive appearance, and can store products for a prolonged period of time.

For frozen breads to be warmed in traditional or microwaves ovens, a range of polyester films is available. The enhancements in the elongation properties of polyester films are likely to expand their usage in construction products and consumer electrical devices. Polyester films are used to make many packaging products like packaging pouch, packaging bags, packaging rolls, food packaging laminates, pharma packaging etc.
