JVCC SCP-04 Silicone-Coated Paper Separator Sheets are paper sheets which are coated on both sides with silicone. Tapes with rubber or acrylic adhesive will not stick to the silicone so if you need to send pre-cut tape pieces to a customer they can be used for that purpose. These are the same sheets we use in our layer-packed boxes (e.g. a case of duct tape or gaffers tape) as separators between the layers. They are purchasable by the pack and 20 sheets or strips come per pack. Made in the U.S. Technical Information - Adhesive: N/A - Thickness: 4 mils (carrier)
