PROBLEM TO BE SOLVED: To prepare a heat fusion film excellent in blocking resistance, or the like, having decreased temperature dependence of heat fusion strength when fused with a heat-sealing layer comprising a low-density polyethylene layer, and capable of being easily released when an article packed therewith is taken out, even though the film has such heat fusion strength as causing no fear that the article packed therewith may leak out when distributed/warehoused, and to provide a packaging material therefrom. SOLUTION: The heat fusion film has a heat fusion layer formed from a low-density polyethylene composition (C) comprising a low-density polyethylene (A) in an amount of 99-55 wt.% and a polypropylene polymer (B) in an amount of 1-45 wt.%. The easily openable packaging material is formed by using the film, and further, a cover material for a package is formed by using the easily openable packaging material. The packaging material has layers formed oppositely to each other, wherein one of the layers is the heat fusion layer formed from the low-density polyethylene composition (C) comprising the low-density polyethylene (A) in an amount of 99-55 wt.% and the polypropylene polymer (B) in an amount of 1-45 wt.%, and the other is a heat-sealing layer formed from the low-density polyethylene. |
