ABSTRACT:
Biaxially stretched, heat shrinkable monolayer and multilayer films comprising very low density polyethylene terpolymers of monomers (a), (b) and (c), where (a) comprises ethylene, (b) comprises a C.sub.6 -C.sub.8 alpha-olefin and (c) comprises 1-butene or 1-hexene, have a very good combination of physical properties and processability including high shrinkage values and puncture resistance.
