PURPOSE:To obtain a film which can not be permeated by liquid water but can be permeated by water vapor and which can prevent malodor and can emit pleasant odor, by stretching a sheet comprising polyethylene and an inorganic filler impregnated with a perfume. CONSTITUTION:A film obtained by molding a mixture of polyethylene and an inorganic filler impregnated with a perfume into a film and stretching this film. In order to further improve the moisture permeability, stretchability, flexibility, etc. useful for, especially, a back film of a disposable diaper, a mixture containing high-pressure process low-density polyethylene (MI >=10) and/or ethylene/alpha-olefin copolymer (crystallinity <30%) in addition to the above mentioned components is formed into a sheet and this sheet is stretched. In this way, a film having necessary properties can be obtained inexpensively. As the inorganic filler added, a porous one is particularly desirable. |
