<p>PROBLEM TO BE SOLVED: To obtain an anti-fogging film only by extrusion without requiring coating or drying by laminating a film specified in moisture permeability. SOLUTION: A plastic film of which the moisture permeability prescribed by JIS Z0208 is below 1,000g/m<2> /24hr is laminated to a film with moisture permeability of 1,000g/m<2> /24hr or more. As a laminating method, a co-extrusion method extruding both components at the same time is used. As a resin constituting the film, at least one kind of a resin selected from the group consisting of a polyether/polyamide block copolymer, a thermoplastic polyester elastomer and thermoplastic polyurethane is used from a viewpoint of moisture permeability. This plastic film has proper moisture permeability and low waterdrop adhesiveness and can be expected to be reduced in the fogging caused by waterdrops even if it is used in the packing of fruit, vegetables or a flower to be preserved at a low temp.</p> |
