(PET) polyester or
polyethylene is an advanced, crystal-clear thermoplastic made of ethylene
glycol and dimethyl terephthalate (DMT). It is higher in tensile power,
outstanding dimensional durability, low humidity intake, and reasonable
physical preservation across a relatively large spectrum of temperature in
contrast with other popular plastic films.
PET Films also offers excellent UV resistance,
excellent electricity, excellent visual clarity, high gloss, and a good gas
barrier, but only a moderate humidity barrier. This is the ideal film for
quality printing and lamination as well as for high-performance sheets and
plastic films. The melting point is relatively high, which makes it suitable
for applications requiring high-temperature sterilization.
Characteristics to
consider to be used in industry
In certain
applications with a long product shelf life, PET can be metalized which
contributes to improved gas-barrier properties. PET film is suitable for a
broad range of commercial, automotive, and electronic applications. In several
specific uses, it is completely recyclable and can be re-processed conveniently
into many other items.
However, Pearlized Film does not quickly decompose, unlike paper and other cellulose
products. However, biodegradable additives are available which improve the
biodegradation without affecting the physical properties of this plastic.
Despite its higher
price, BOPET has found many high volume applications that require this stronger
and dimensionally stable film. A major drawback of BOPET is the higher
manufacturing costs and higher capital investment in equipment.
BOPET finds several
high volume applications, given its increased price, which allows this film to
be stronger and more compact in measurements. BOPET's main drawback is higher
manufacturing costs and decreased infrastructure capital spending.
Application in
industry
For more demanding
applications in food and non-food films, PET is usually an excellent choice.
Microwave, plastic packaging, backing paper, plastic sheet, protective
coatings, such as solar and safety window films, release films, insulation
films for transformers and versatile circuits are the main applications. The
PET can be a barrier film and is used often (for example, coffee, and tobacco
packaging).
Conclusion
Because of its low
odor, strong chemical tolerance, and inertness, a significant range of PET
grades are ideal for FDA applications.
Corona treated PET
film is marketed in
various forms, thicknesses, widths, and properties customized for particular
applications.
