What is the Operating Temperature of PET Film?

---

PET film is a common plastic package film material with good transparency, toughness and high temperature resistance, which is widely used in packaging, printing, electronic products and other fields. Due to the special structure and material properties, the different operating temperature of PET film result in different application limitations.

What is the Operating Temperature of PET Film?

The operating temperature range of PET film is generally between 40°C and 80°C. Beyond the operating temperature range, PET film will be damaged and decreased mechanical property.

PET plastic film will melt and deform, lose the original properties if over the melting temperature 260°C. Avoid exceeding the melting point 260°C, being irreversible damage when using PET film.

The soften temperature heat deformation temperature of PET film is about 70°C-80°C, will be undergo thermal deformation and lower flatness, transparency and tensile strength. To keep the excellent packing and print quality, avoid to exposure PET film under high temperature.

PET film also has certain low-temperature resistance and can maintain certain mechanical properties and transparency at lower temperatures. However, in low temperature environments, PET films become brittle and prone to breakage. Therefore, when using PET film in a low-temperature environment, care should be taken to avoid violent alternations of hot and cold to avoid damage to the film.

PET film will be brittle and prone to breakage in violent alternations of hot and cold although has certain low-temperature resistance.

POLYSAN, as a professional plastic film sheet China factory, we produce and supply high quality PET film with multiple performance for different application. To ensure the best performance and safety of PET film, POLYSAN recommend testing and verification are also requirement on a case-by-case basis in actual applications as the specific use temperature of PET film is also affected by thickness and processing technology.
