ReTac® Duo is a 1 mil (25μ) clear PET film, coated on both sides with adhesive. It has a permanent adhesive on one side to be used on graphic prints and ReTac® ultra removable adhesive on the other, allowing it to be easily removed and re-positioned for repeated use. ReTac® Duo is designed to adhere to walls, doors or any smooth surface without leaving behind residue or damaging the surface when removed. The adhesive is self-wound on a two-sided, PE coated siliconized Kraft release paper.
