<p>A packaging material and methods of manufacturing and disposing of said material. The packaging material, containing a polymer adjustable in water-solubility by varying the temperature of water used therefor and/or water-soluble resin and vegetable fibers as reinforcing components, is strong enough for the use under the normal condition and usable for various kinds of packaging. The method enables efficient manufacture of a packaging material excellent in moisture- and water-proofness by: utilizing the molding method to be applied to normal thermoplastic resin; making a filmy matter from aforesaid polymer; or spreading aqueous solution of said polymer on the material paper sheet or using wet laminates of material paper sheets. The packaging material of this invention is dissolved into solution by appropriate warm water, need not be removed from paper sheets or waste paper stock which are wrapped or bound by this packaging material, and, when used as waste paper stock, exhibits effects of increasing the strength of the product.</p> |
