<p>PURPOSE:To provide base paper of a paper container having a light weight, a high strength, water resistance, suitable water absorption and moisture absorption and further base paper of a paper container in which an environment is not impaired. CONSTITUTION:A zigzag.corrugated structure (120g/m<2> of corrugation, 150g/m<2> of smooth paper) 5 is used as a support, and a water resistant film 4 in which a film of vionore (phonetic notation #1000, 15mum (Showa Polymer Co.) is thermally laminated, and a cellophane sheet (PT-300, Tokyo Cellophane Paper Co.,) 3 are sequentially bonded thereto. Further, a semipermeable film 2 in which pulp paper (quinocloth (phonetic notation) KD-40, Honshu Papermaking Co.) is pressbonded with 60g/m<2> of powderlike starch syrup (Sanmatsu Kogyo Co., SLD) while thermally humidified is thermally bonded to form water absorption base paper 1.</p> |
