PET film quality inspection

PET film quality inspection

1. Pet film characteristics

PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability. It can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical grade mirror surface protection and other fields.

2. Thermal transfer PET film

When PET film is used to make thermal transfer film, the high tensile strength, good thermal stability, low thermal shrinkage, smooth surface, and good peelability of PET film are used to achieve the production of thermal transfer film and ensure its stable quality.

3. Thermal transfer PET film inspection and judgment

So, now that we know the characteristics of PET film, how to judge the quality of PET film? At present, authoritative testing agencies use the following parameters and reference standards to inspect and judge PET film:

PET film verification standard

When these inspection contents are judged as superior products, the quality of thermal transfer printing film made from such PET film must also be excellent.
