PURPOSE: To obtain the film or sheet which is thin and has air permeability and deodorant or aromatic property by subjecting a polyolefin resin compsn. contg. a polyolefin resin, filler and radical generating agent and further a deodorant or perfume to stretching after melt molding.

CONSTITUTION: The filler is compounded at 50 to 400 pts.wt., the radical generating agent at 0.0001 to 0.1 pt.wt. and the deodorant or perfume at 0.1 to 40 pts.wt. with 100 pts.wt. polyolefin resin and the mixture is put into an ordinary blender or mixer and is mixed. After an unstretched film is molded, the unstretched film is stretched longitudinally (the take off direction of the film) or transversely at need to form the stretched film. The film or sheet which is thin and has the exceedingly outstanding moisture permeability and gas permeability and has also the excellent absorptivity and directivity of odorous components is obtd. in this way.
