Claims
- 1. The combination of an article and a multilayered cast film, said article being twist-wrapped by said film, the elongation at break of said film being greater than 100%, and said film comprising:
- A) at least one layer consisting essentially of a crystalline homopolymer of a C.sub.3 -C.sub.6 .alpha.-olefin, or a crystalline, random copolymer of propylene with ethylene or a C.sub.4 -C.sub.10 .alpha.-olefin, or a crystalline, random copolymers of propylene with ethylene and a C.sub.4 -C.sub.10 .alpha.-olefin, or a composition of crystalline, random copolymers selected from the group consisting of crystalline, random copolymers of propylene with ethylene, of propylene with a C.sub.4 -C.sub.8 .alpha.-olefin, and of propylene with ethylene and a C.sub.4 -C.sub.8 .alpha.-olefin, the elongation at break of said layer being greater than 350%; and
- B) at least one layer (Layer B) consisting essentially of a propylene homopolymer, or a propylene copolymer with ethylene or a C.sub.4 -C.sub.10 .alpha. -olefin, or a propylene copolymer with ethylene and a C.sub.4 -C.sub.10 .alpha.-olefin, the elongation at break of said homopolymer and copolymers being lower than 30%, the flexural modulus of said homopolymer and copolymers being higher than 1600 MPa, and the M.sub.w /M.sub.n of said homopolymer and copolymers being 8-30.
- 2. The combination of claim 1, wherein the elongation at break of Layer B is lower than 25%.
- 3. The combination of claim 1, wherein the elongation at break of the film is greater than 200%.
- 4. The combination of claim 1 in which said composition comprises (all percentages being by weight):
- (1) 30-65% of a copolymer of propylene and a C.sub.4 -C.sub.8 .alpha.-olefin, the propylene content of which is 80-98%; and
- (2) 35-70% of a copolymer of propylene and ethylene, the ethylene content of which is 2-10%, or a copolymer of propylene, ethylene and a C.sub.4 -C.sub.8 .alpha.-olefin, the ethylene content of which is 0.5-5%, and the C.sub.4 -C.sub.8 .alpha.-olefin content of which is 2-10%.
- 5. The combination of claim 1 in which said article is a piece of candy.
