Some do, and some don’t. Plasticizer is used to give Vinyl it’s soft feeling and greater pliability. The softer the Vinyl the more plasticizer has been used. Our ClearLay Rigid Vinyl Film and Sheets do not have any plasticizer in them, so they are relatively hard. On the other end of the scale is our Grafix Cling Vinyl sheets that are loaded with plasticizer, which is what makes them adhere to ultra smooth surfaces. Flexible Vinyl Sheets have a measured amount of plasticizer to give them a targetted softness (called “Hand” in the Vinyl Industry).
