Abstract
PURPOSE:To impart water resistance, mechanical strength and slippage resistance, to enhance manufacturing efficiency and to shorten a manufacturing process, by forming an inner bag from a film obtained by stretching a specific polyethylene resin under a specific condition. CONSTITUTION:In a packing bag wherein an exterior composed of a paper layer is combined with an interior composed of a stretched film based on linear polyethylene, a polyethylene resin containing at least 50wt.% of linear polyethylene having a melt index of 2g/10min or less, fluidity of 75 or less and density of 0.910-0.965g/cm<3> is used to mold a non-stretched film or sheet and this film or sheet is stretched in at least one direction at areal magnification of 1.2-9 to obtain a film which is, in turn, formed into an inner bag. Only linear polyethylene may be used as the polyethylene resin but, when linear polyethylene is used as a main component and branched low density polyethylene is compounded therewith, film moldability and stretchability are enhanced.
