A cold seal release film in the form of a monolayer film or an outer layer of
a
multilayer film. The cold seal release film includes a nucleating agent and 10%-100%
by weight of the polymer composition of a polymer selected from the group consisting
of 1-butene homopolymer, 1-butene/ethylene random copolymers having over 50% by
weight 1-butene therein blends of the 1-butene homopolymer and the 1-butene/ethylene
random copolymers, and 90%-0% by weight of the polymer composition of a polymer
selected from the group consisting of ethylene random copolymers of polypropylene,
butene random copolymers of polypropylene and ethylene-butene random terpolymers
of polypropylene.
