What are the three major substrates of thermal transfer film?
The substrates of thermal transfer film are generally divided into three categories, namely PET film, OPP film and PVC film.

1. PET film

The toughness of PET film is the best among all plastic films. It has good transparency and glossiness. Compared with ordinary films, its tensile strength is better and will not cause large tensile loss to the pattern.

PET film has good heat resistance. It can transfer the transfer film by hot pressing at high temperature. It has very good flatness after pressing. The printed product has high gloss. It is currently the most widely used thermal transfer substrate.

2. OPP film

OPP film is also called protective film. It is a plastic film based on OPP. Its surface is colorless, odorless, non-toxic, and has high tensile strength, good rigidity and toughness.

The film surface is not only very smooth, but also very transparent. During the glue coating process, its viscosity is not easy to change, and it is easy to stamp and die-cut. Since OPP material is easy to absorb static electricity, it must be treated with static electricity after printing.

3. PVC film

PVC film is made of PVC material. This material can not only be used as a substrate for thermal transfer film, but also can be made into various toys, stationery, cosmetics, doors and windows. It is one of the most widely used decorative materials in plastic materials.

As a member of the substrate, PVC film is divided into soft PVC film and hard PVC film. Hard PVC film is generally used as a substrate for automobiles and vacuum blister thermal transfer films. It has good tensile strength and good printing performance. It is a more commonly used thermal transfer substrate.
