Any more material for tear tape?
Several years ago, teartape manufacturers were using cellophane, BOPP ( bi-oriented polypropylene ), PET ( polyester ) films to produce teartape, with the development of the technology, above films are rarely used because of some disadvantages of the film (e.g. cellophane is too moisture sensitive, inappropriate elongation for BOPP etc.)
