摘要
The invention concerns a low-density polyethylene-based polymer composition for producing films or sheaths. The present invention provides a low-density polyethylene-based polymer composition for manufacturing films or sheaths, particularly thin films or sheaths having a thickness of less than twenty microns, said polymer composition being constituted by a graft copolymer comprising at least one styrene monomer, possibly mixed with at least one acrylic monomer, said monomer or monomers being grafted onto a trunk constituted by a pre-formed combination or alloy containing by weight, 50 to 95% low-density polyethylene and 50 to 5% high density polyethylene and/or polypropylene, the proportion of the grafted styrene monomer or mixture of monomers being comprised between 5 and 50% by weight of said graft copolymer.
