What is PET?

Density 1.4

Polyester film is a high-performance, crystal clear thermoplastic made from Polyethylene Terephthalate (PET) resin.

In comparison with other common plastic films, PET film has high tensile strength, excellent dimensional stability, low moisture absorption, and good retention of physical properties over a fairly wide temperature range.

It also has superior UV resistance and excellent electrical properties, and good optical clarity. Because of its higher price relative to PVC, PE, and PP film, it is generally considered a specialty film.

PET Film – 150°C (302°F) and as cold as -70°C (-94°F)

Properties

higher tensile strength
excellent dimensional stability
low moisture absorption
good retention of physical properties over a fairly wide temperature range
superior UV resistance
excellent electrical properties
good optical clarity
high gloss
good gas barrier
moderate moisture barrier
Application

aroma barrier film (e.g. coffee and tobacco packaging)
release films
microwave
printed films
medical packaging
plastic wrap
tape backing
plastic cards
protective coatings such as solar
safety window films
transformer insulation films
flexible printed circuits
What is Bi-axially Oriented?
Biaxially oriented, means that the film is stretched in two different directions to increase strength and modulus (lower elongation and higher stiffness).

Flexible Packaging Innovation What Is Flexible Packaging? The flexible packaging is defined as a package or any part of a package whose shape can be changed readily.   Use Of Flexible Packaging Such packaging is used in consumer and institutional products and industrial applications. Flexible packaging can be made of plastics, film, paper, or aluminum foil and employed to increase the shelf life of the product and provide protection. Flexible packaging is widely extendible to diverse product categories like bags, pouches, and wraps. Advantages Of Flexible Packaging The manufacturing and use of flexible packaging demonstrate sustainable advantages such as reduced greenhouse gas emissions and efficient resource conservation .The flexible packaging market is anticipated to grow in the forecast period owing to driving factors such as increasing preferences of both consumers and producers towards convenience products and improved shelf-life. Growing i...
