Abstract (en)

[origin: WO0015728A1] A coated sheet has a heat-activatable adhesive coating of thermoplastic polyurethane having a melting point of 40 to 100 DEG C. The coating may be crystalline and have an average crystal size below 10 mu m. The coating, when molten, may remain tacky for a period of from 2 to 50 seconds. Preferred processes comprise heat activating the coating and subsequently cold or cool sealing, for instance to form a packet around a heat-sensitive material.
