2022-05-06

In the heat transfer process, release film coating process is very important, involving a variety of materials are not the same, following simple explain coating process to you:


Coating step one:

First, apply a back coat to back of PET blank film,provides anti-sticking and anti-static coating on the back of PET film, which can partially reduce the release paper cost and reduce static electricity generation,so that let the paper go more smoothly.
