A Short Guide To Pet Film Coating

In the past things which had a significant use in our daily lives were originally made from wood, iron, copper, aluminium and other metals and non metals. These easier to extract and became the basis for many protective films and storage compartments. These days many of these materials have been replaced by plastic. Practically everything we use, from food packages to supermarket carrier bags are made from plastic, making it the most versatile and durable material available.

As technological advancements have made it possible to replace naturally occurring materials, it has been possible to replicate or even use man-made materials that just as strong if not stronger in places. Plastic is just one of the most important materials in our everyday lives and cannot be ignored. Polyester is another material which acts as a replacement coating allowing for any weak or fragile material to extend its life span and provide a much more aesthetically appeal look to any object.

One such coating in particular is polyethylene terephthalate film (PET film) or biaxial-oriented polyethylene terephthalate (boPET) film. This was the first of its kind and was created to meet the demands of better chemical and physical properties. Its high tensile strength was designed so that it would replace steel, however the main difference was that it was transparent in the way it looked and had similar dimensional properties to iron and wood. The first PET film was developed during the 1950s by two companies, DuPont and Imperial Chemical Industries (ICI).

These films were available in different types, such as plan, metalized, barrier coated, anti-static and adhesion treated. Some of the trade names that refer to this kind of polyester film are Mylar film and melinex film, with the former most commonly referring to the film and plastic sheets. Mylar sheets can often be found with varying finishes such as Haze Black, Clear, White, Moderate to High and other such finishes, with each thickness differing from each other.

The film is used for many reasons and is most beneficial for enhancing glass. When used for lamination the glass is protected from UV rays and external radiation that may be harmful to the fibre. This kind of laminate barrier can be found in different colours. Very often these can be found on LCD or Plasma screen television with diffusion coating polyester, also known as anti reflection and anti glare coating. These are also used within the medical industry, namely on X-ray films and medical strips. Other every day uses include credit and debit cards, identification cards, print photography films, digital printing and other such printing materials.
