3M™ Tamper-Indicating Label Material 7937 is a durable, high performance material that offers excellent thermal stability, moisture resistance and chemical resistance. This material utilizes 3M™ Adhesive 300, which has excellent quick tack and also bonds well to a variety of surfaces including LSE plastics.
Tamper Evident Labels for Security Across Applications and Industries
Designed to meet specific challenges in tamper-resistant labeling, our 3M™ Tamper Evident Label Materials are available in a broad selection of facestocks, adhesives, colors and patterns. Labels are supplied in paper, vinyl, acetate and polyester for durability during processing and after application; many are destructible, making it easy to identify attempted removal. They feature our specially-formulated acrylic adhesives, which include 3M™ High Strength Acrylic Adhesive 300 for quick flowing application and fast lamination to textured plastics, foams, fabrics and coated papers. Our universal Adhesive 350 is excellent for challenging substrates like low surface energy plastics and oily metals. 3M™ Adhesive 320 delivers a very high bond strength; and 3M™ Adhesive 1410 is formulated for adhesion to polyolefins.
The combination of materials can be used for printing applications including thermal transfer, digital, inkjet, laser, and dot matrix printing processes. A range of liners includes glassine, polycoated Kraft, densified Kraft and supercalendered Kraft for dimensional stability during processes such as high-speed die-cutting and matrix stripping.
