PURPOSE: To prepare a fruit cultivation bag having effects on the prevention of fruits from insects and birds and the increase in the saccharide degrees and coloration degrees of the fruits by drawing a polyolefin resin film compounded with a filler in a monoaxial direction and subsequently forming the prepared moisture-permeating film into the bag.
CONSTITUTION: A bag comprising a moisture-permeating film prepared by drawing a film or sheet at least in a monoaxial direction 1.2 times or more, the film or sheet being prepared by melt-molding a composition comprising 100 pts.wt. of a polyolefin resin and 25-400 pts.wt. of a filler. The employed polyolefin resin is preferably high density polyethylene, polypropylene or linear low density polyethylene. On the consideration of the drawing peelability of the filler with the polyolefin resin and also on the consideration of the particle uniformity, availability, etc., of the filler, calcium carbonate, talc, clay, etc., are especially preferable as the inorganic filler and wood powder, pulp powder, etc., are employed as the organic filler.
