3M™ Sheet and Screen Tamper Evident Label Materials 7937 is a 58 micron, matt white polyester facestock with a 20 micron acrylic adhesive 300 on a 170 micron polycoated kraft liner. Our tamper indicating label shows a VOID message when removed from the substrate.
For a tamper indicating label that shows a VOID message when removed from the substrate, use 3M™ Sheet and Screen Tamper Evident Label Materials 7937. The tight VOID pattern allows for the creation of smaller labels. Our label material is ideal for use as a warranty seal, authentication label or closure seal, with a gloss topcoat for excellent abrasion and chemical resistance. A heavy adhesive coat weight gives high temperature performance and allows for excellent adhesion to textured surfaces, low surface energy plastics, powder paint coatings and oily metal surfaces. It has a 170 micron screen lay-flat liner, and is UL recognised and CSA accepted. 3M Performance Label Stock Materials offer a wide range of products for long term durability and adhesion with automotive chemical resistance and outdoor durability.
