Double-surface internal pasted jet printing material

[0030] During production, use PET release film or paper release film as the raw material of the isolation layer, first apply pressure-sensitive adhesive (commonly known as self-adhesive) on the release surface of the isolation layer, the self-adhesive can be transparent or white Wait for different colors, dry, and then stick the temporary release film on the surface of the pressure-sensitive adhesive of the isolation layer, so that the pressure-sensitive adhesive is in a protected state. Then, the isolation layer coated with pressure-sensitive adhesive is placed on a punching machine to punch holes, so that the isolation layer is formed into a porous isolation layer 5 with through holes 51 , and the through holes 51 penetrate through the pressure-sensitive adhesive layer 4 . In this way, after the holes are punched, there is no pressure-sensitive adhesive in the places where the isolation layer has holes. Then, use the white PVC film as the ink-absorbing base material layer 3,...
