When is a vinyl not a vinyl? When it's PVC free. R-Tape's Chalk-Talk is a specialty film made from a PVC film designed specifically for use in homes, schools and day care centers. The PVC free face film means it's fully CPSIA compliant and certifiably safe for use in children's decor. The 6 mil film thickness and removable adhesive means you can make wall graphics that are easy to remove and re-position with no damage to painted surfaces. Fully compatible with chalk and chalk ink markers.
