Abstract

PURPOSE: To provide packing material with gas permeability by coating plastic films partially on a basic sheet for forming ventilating portins partially.
CONSTITUTION: Plastic films 2 of predetermined patterns are adhered with a basic sheet 1 partially and a protection sheet 4 with gas permeability is adhered on the said plastic films 2. Basic sheet 1 is made of staplized heat adhessive thermoplastic resin such as polyethylen, polypropylene and the like and suitable weighing of sheet is 30 W 100 g/m2. Plastic film 2 is made of polimerized ethylene-vinyl acetate, polimerized polyvinyl acetate-acryl and the like and suitable coating dencity is 3 W 30 g/m2. Undercoat 3 and/or protection sheet 4 may be attached if necessary. In case the said sheet is used as packing bags, a space between one side of said compound sheet and the other side of plastic film 5 is filled with substance to be filled and the peripheries of both sheets are sealed together by thermal sealing.
