Abstract:
1. A peelable packaging film comprising: a) a first monolayer heat shrinkable thermoplastic substrate comprising a first surface and a second surface; b) a second non-heat shrinkable thermoplastic substrate comprising a first surface on a first surface layer and a second surface, wherein both first surfaces of the first and second substrate each comprises a polyolefin and has a surface energy of at least 36 dynes/cm; wherein said second thermoplastic substrate has a Heat Shrinkage value of between 0 and 10% at 102° C. in either the machine or transverse directions; c) an adhesive layer comprising a polyurethane and contiguously disposed between and in contact with each of the first surfaces of the substrates; and d) a peelable interface provided between the adhesive layer and the first surface of the first monolayer heat shrinkable thermoplastic substrate.
