Are you having problems with dye migration? Then Subliblock® is your solution!

Many of today’s imported polyester fabrics are colored with inexpensive low energy dyes. These dyes migrate quickly into pressed materials with minimal heat. They can also bleed into pressed materials slowly over time at normal room temperature!

Subliblock® films are designed with an additional layer to help prevent the dye from migrating through your transfer image. No nylon.

Please note: Subliblock® White is now part of Subliblock® Turbo with a new part number – SB-3105-T.  View it here.
