Usually removing the paper surface protection masking on plastic
is easy. It is simply a matter of starting in a corner and rolling it off of
the surface. Many manufacturers and fabricators recommend rolling the masking
around a cardboard tube.
Over time the adhesive can build in adhesion to the surface of the
plastic. Masked plastic sheet, which has
been exposed to heat, can be extremely difficult to remove. If the masking is
exposed to sunlight, the adhesive will crystallize and will be impossible to
remove.
If the paper masking is difficult to remove, and comes off in
little bits and pieces, try saturating the sheet in water. Some people recommend
spraying the masking with a product, such as Goo Gone. Allow the cleaner time
to penetrate the paper and soften the adhesive.
Do not allow the cleaner to dry.
After 20 to 30 minutes, try to peel the masking from the surface
of the plastic. If the masking is still difficult to remove, resaturate the
paper and allow more time for the cleaner to work.
After removing the paper masking, clean the surface of the plastic
sheet with a mild, non-abrasive detergent and water. Gently dry the surface of
the plastic with soft toweling. Drying
with minimal pressure will minimize the chance of scratching. Do not clean the
sheet with solvents such as Acetone, Xylene or Toluene. These strong solvents
subject the plastic to chemical stresses, which potentially could weaken or craze
the sheet.

Vinyl Application to Corrugations. Learn how to apply vinyl graphics to corrugations in a relaxed state. Forcing films into the valleys of corrugations puts too much mechanical stress on the film. Sooner or later, the vinyl will lift or tent in valleys. Click to Link
Applying Air Egress Vinyls. Vinyl films with air egress release liners have almost eliminated bubbles and wrinkles from applied graphics. Air egress release liners with their highly textured surface structure are problematic. Not much will stick to these liners other than the vinyl film. At RTape our best premask solution for air egress liners is a special Conform® tape called 4761RLA. Click to Link
