Masking Your Print and Cut Materials is as Easy as TTD! Most application tapes in the industry are manufactured to transfer sign vinyl which doesn’t require heat. When using these tapes to apply Siser products, you may be left with an adhesive residue. Additionally, the tape may be difficult to remove which slows down the production process. An extended amount of time was spent formulating a transfer tape that works perfectly with our heat transfer materials. This CLEAR mask allows you to accurately place the image on the garment then releases easily after heat application.
