The Principle of Heat Transfer Printing Film

The heat transfer printing film is a kind of medium material for heat transfer printing.

Denim Heat Transfer Film process principle and heat transfer paper similar, only the heat transfer film substrate or transfer media is transparent film, the bottom membrane material is mainly three kinds of opp, PET, PVC.

1. OPP: larger flexibility, larger impact pressure, but poor heat resistance.

2. PET: low flexibility and good stability. The most widely used. 80% of the heat transfer film is made of this material.

3. PVC: corrosion resistance and good insulation.
