To provide a method for producing an insect-proofing film by melt- mixing a polyolefin resin and an inorganic filler, with an encapsulated insect- proofing agent.
This method for producing the insect-proofing film is characterized by melt-mixing 0.01-10 pts.wt. capsules including the insect-proofing agent with 20-80 pts.wt. polyolefin resin, and 20-80 pts.wt. inorganic filler, forming the melt-mixed product into a raw sheet by an inflation method or a T-die casting method, and monoaxially or biaxially orienting the resultant raw sheet so that the total area draw ratio may be 1.5-36 times according to the required moisture permeability. The film produced by the method can maintain the insect-proofing effects for a long time by suppressing the rapid migration of the insect-proofing agent to the surface of the film, has moisture permeability, and is especially suitable for a bag for a fruit tree.
