PET Film / Polyester film

Polyester film, often called PET (Polyethylene Terephthalate), has outstanding physical properties for a plastic film. These include high tensile strength, chemical resistance, thermal stability, flatness, clarity, high temperature resistance, and thermal and electrical insulation properties.

With hundreds of film types in a wide range of thicknesses and coating combinations from 8 microns (0.008mm) to 500 microns (0.5mm), polyester film provides exceptional performance in a wide range of applications and is often far superior to other substrates such as PVC, acetate and polypropylene.

The most commonly used micron thicknesses are 12 15 19 20 23 30 36 50 75 100 125 175 250 and 350 micron polyester films, and thicknesses above this are now considered sheet group polyesters.

How is polyester produced?
Polyester or Polyethylene Terephthalate (PET) is a plastic material produced by reacting terephthalic acid with ethylene glycol, two substances produced in the crude oil/naphtha cracking chain. Despite its semi-crystalline structure, it has excellent clarity.

What are the types of polyester films?

In fact, the answer to this question cannot be given at once. Polyester film finds its place in almost many sectors. While it is used as an insulation material in communication cables, it is used safely in many industrial areas up to 250 degrees due to its heat resistance. There are also polyester films used as oven bags for food. Main polyester film types; We can list them as corona treated polyester film, plen polyester film, chemical polyester film, heat sealable polyester film, metalized polyester film, white polyester film, colored polyester film.

What are the advantages of polyester film?
Polyester film has many advantages over other plastic products; the most obvious of which are thermal stability and tensile strength. It also has excellent gas and moisture barrier properties, good clarity and chemical stability.

The many advantages of polyester film can be exploited in different ways according to a wide range of possible applications, some of which are listed below.

Power – hanging displays, labels and tags
Clarity – extreme lamination, archival storage, security window film
Thermal Stability – ovenproof packaging film, electrical insulation at high temperatures
Printability – with various techniques such as offset, flexo, gravure, digital
Whiteness – mostly as a synthetic paper for printing applications
Hardness and Flatness – in tickets, labels and card applications
Sealing – heat sealable over a wide temperature range
Chemical Stability – medical test strips, hazardous materials labeling

It is also widely used on the top layer of many grocery product packages due to its heat resistance and barrier properties.

In addition to these areas, it is a product that is open to new ideas to find areas to be suggested according to customer demands.
