摘要： Described is the presence of both a pro-rad linking agent and irradiation such as electron beam irradiation, in the manufacturing process for making an oriented, i.e. heat-shrinkable, polymeric film. The presence of both results in an amount of cross-linking that is effective to accomplish an increased orientation rate during manufacturing.

摘要： A single-sheet gusset bag for photographic photosensitive materials comprising a laminated sheet of which the inner surface layer is a light-shielding polyolefin resin film layer and the outer surface layer is a heat-resistant flexible sheet layer, and having a botom seal portion fixed by a hot-melt adhesive having a softening point by ring and ball method of 75 to 115 C of which the coating amount in the center portion is less than the coating amount of the side portion.In the gusset bag of the invention, the bottom seal portion can be effectively sealed without incidence of fogging and uneven gloss caused by the heat of the hot-melt adhesive. Since the gusset bag is formed of a single sheet, packaging is readily achieved. The cost of the packaging material is also inexpensive.
摘要翻译：一种用于照相感光材料的单片角撑板袋，其包括内表面层为遮光性聚烯烃树脂膜层的层压片，外表面层为耐热柔性片层，并且具有固定通过环形球法的软化点为75〜115℃的热熔粘合剂，其中心部分的涂布量小于侧面部分的涂布量。在本发明的角撑板袋中，可以有效地密封底部密封部分，而不会由于热熔粘合剂的热量而引起起雾和不均匀的光泽。由于角撑板袋由单张纸形成，容易实现包装。包装材料的成本也便宜。

摘要： A plastic bag of polyolefin material such as polyethylene, for packaging materials, comprising particles of less than 50 .mu.m, and a closed bag containing such materials and a foil material for such a bag.The foil wall of the bag is provided with venting apertures with smooth edges, obtained by laser radiation, having a maximum size of 50-100 .mu.m; the distance between the venting perforations is such that the tensile strength of the foil is substantially the same as the tensile strength of the similar non-perforated foil.In a low density polyethylene foil of a thickness of 130-190 .mu.m distance between the perforations of 80 .mu.m is more than 20 mm, in a linear low density polyethylene foil of about 50-110 .mu.m the perforation distance is at least 5 mm.The bag may consist of two perforated foil layers, the perforations being staggered with respect to each other.
