摘要

PURPOSE: To provide a highly shock resistant and cushion packing bag packs a chemicals filling bag, by using a laminated sheet product having a non- adhesive part and produced by applying a remover in order to form a void between an internal layer sheet and an external layer sheet except for the marginal part. ;CONSTITUTION: A packing bag D has a laminated sheet product 5 produced by bonding a pair of external layer sheet 1 and a pair of internal layer sheet 2 having a similar shape to the external layer sheet 1, through an adhesive layer 4 made by applying an adhesive 4' to a inner face 3 of the external layer sheet l. The body of the packing bag is formed by laminating each inner face 6 of the internal layer sheet 2 each other and heat-sealing a marginal part 14 except for an opening 7. The adhesive layer 4 has a non-adhesive belt part 9 at the center thereof in the vertical direction, thereby enabling an outer air to go to left or right direction. A remover is applied to the outer side of the internal layer sheet 2 except for some part of a marginal part 6 and the opening 7 and enabling a void 12 to be formed between the sheet l and the sheet 2.;COPYRIGHT: (C)1995,JPO
