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.
