TEAR-TAPE FOR POLYMERIC PACKAGING FILM TEARABLE PACKAGING FILM WITH THE TAPE HEAT-SEALED THERETO

摘要

A tear-tape for attachment to a polymeric packaging film comprises a thermoplastic polymeric substrate having on a surface thereof a layer of a sealing resin comprising a blend of an ethylene-vinyl acetate copolymer and a plasticizer therefor. Bonding between the tear-tape and a polymeric packaging film substrate is enhanced by the presence of the plasticizer.
