<p>PURPOSE:To provide a packing bag of the sheet-like resin material capable of being torn in a predetermined direction, excellent in bag tearing strength, resistance to low and high temperature, shape retainability and printability and provided with the feeling of a favorable taste. CONSTITUTION:A resin multilayer (b) containing a resin mixed layer (bt) is bonded to the paper layer (a) of a rayon mixed paper (mixing ratio: rayon/wood fiber = 50/50 per unit area of 20g/m<2>) and the resulting laminate is then made into the form of a laminated packing bag-like material. The resin mixed layer (bt) consists of 75wt.% 6-nylon and 25wt.% low-density polyethylene and the resin multilayer (b) [layer ratio: bt/bb/bs=30/20/50] is used which has a modified polyethylene resin layer and a low-density polyethylene inner layer bonded to the resin mixed layer (bt). The bag-like material is of the laminated sheet having (b) and (a) bonded together with a polyurethane adhesive agent.</p> |
