What is PET thermal transfer film

1-What is PET thermal transfer film
Thermal transfer film printing is basically PET thermal transfer film printing.

PET film has high tensile strength, good thermal stability, low thermal shrinkage, smooth surface, good peeling, and extremely small thickness deviation. Due to its excellent material properties, PET thermal transfer film is widely used as the base film in the thermal transfer industry.

2-Material properties of PET thermal transfer film
1. PET thermal transfer film has good mechanical properties, and its impact strength is 3 to 5 times that of other films, and it has good folding resistance.

2. PET thermal transfer film is resistant to oil, fat, dilute acid, dilute alkali, and most solvents.

3. PET thermal transfer film has excellent high and low temperature resistance. It can be used for a long time within the temperature range of 120℃, and can withstand high temperatures of 150℃ and low temperatures of -70℃ for short-term use. The mechanical properties are little affected by high and low temperatures.

4. PET thermal transfer film has low gas and water vapor permeability, that is, it has excellent gas, water, oil and odor barrier properties.

5. PET thermal transfer film has high transparency, can block ultraviolet rays, and has good gloss.

6. PET thermal transfer film is non-toxic, odorless, hygienic and safe, and can be directly used for food packaging.

Because PET thermal transfer film has good stability, uniform tension, and extremely small thickness deviation of the film, it is the most widely used.

3-PET thermal transfer film printing process classification

PET thermal transfer film printing can be divided into the following according to its effect:

1. Ordinary PET thermal transfer film printing
Ordinary PET thermal transfer film printing, that is, PET thermal transfer film printing process without any special effects, is a printing process that simply reproduces the pattern.

2. Aluminum-plated PET thermal transfer film printing
Aluminum-plated PET thermal transfer film printing is actually based on ordinary PET thermal transfer film, combined with aluminum plating process, which not only maintains the high performance of general thermal transfer film, but also adds metallic luster to PET thermal transfer film.

3. Laser PET thermal transfer film printing
Laser PET thermal transfer film printing goes a step further on the aluminized PET thermal transfer film, adding laser effect to make the product surface pattern more dazzling.

It can be understood that the higher the effect of the product, the higher the difficulty of PET thermal transfer film printing, the order is:

Laser PET thermal transfer film > aluminized PET thermal transfer film > ordinary PET thermal transfer film
