<p><P>PROBLEM TO BE SOLVED: To provide a paper container which prevents a deterioration in contents etc. , by giving light shielding properties and heat resistance to the packaging material of the paper container for milk, juice, coffee, alcoholic beverages, etc. , simplifies the lamination structure of the packaging material without spoiling the light shielding properties, and is excellent in heat resistance, storage properties, and appearance designability. <P>SOLUTION: In the paper container obtained by box making by laminating a light shielding resin layer, an adhesive resin layer, and a thermoplastic resin layer in turn on the inner surface of a paper substrate layer and using a lamination material obtained by laminating/constituting a thermoplastic resin layer on the outer surface of the paper substrate layer, the light shielding resin layer contains titanium dioxide (which is) at least 0.1μm in particle size and titanium dioxide (which is) 0.1μm or below in particle size. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
