Scotch tape

Description

[3M, St Paul, MN] A registered trademark for a series of semitransparent or transparent pressure-sensitive tapes. Scotch® tapes were introduced in 1925. The initial tapes had cellophane substrates with a natural rubber adhesive mixed with oils and resin (Hatchfield 2001). These early tapes became brittle and yellow with age and often emitted oily (BHT antioxidants) and volatile (sulfur, formic acid, formaldehyde) products. Since 1953, Scotch® tapes have a more stable cellulose acetate substrate with acrylate adhesives.
