PROCESS FOR PRODUCING OF SELF-ADHESIVE TAPE BASED ON POLYPROPYLENE

摘要

A co-extruded self adhesive band contains an antistatic polypropylene supporting foil. The adhesive coating is based on an acrylic acid ester, acrylate and/or copolymer modified aq. dispersion. The backing coating layer, which ensures sepn, contains ground minerals. The supporting foil is bi-axially oriented and crown discharge or flame treated where the adhesive is applied 4-5 wt% residual water is removed from the adhesive coating by drying with the application of a 70-100 degC temp differential maintained at alternate sides of the foi
