摘要： This invention discloses an inflatable airbag without a heat-resisting layer and its manufacturing method: t: the inflatable airbag comprises two cavity films, wherein the boundaries of the two cavity films are glued together to form an airtight space; the inflatable airbag further comprises two valve films which are arranged between the two cavity films; first heat-seal lines are arranged at top ends of the valve films; the valve films and the adjacent cavity films are glued together through the first heat-seal lines; the inflatable airbag further comprises second heat-seal lines, wherein the second heat-seal lines comprise disconnected areas and heat-pressing areas which are arranged alternately; in the heat-pressing areas of the second heat-seal lines, the two valve films and two cavity films are completely glued together; an inflation channel is formed by portions of the two cavity films above the second heat-seal lines ; a bag body is formed by portions of the two cavity films below the second heat-seal lines; in the disconnected areas of the second heat-seal lines, air inlets leading to the bag body from the inflation channel are formed between the two valve films; An inflation inlet is arranged in the inflation channel. According to the inflatable airbag of the invention, materials of an ink heat-resisting layer in the prior art are not needed cost is reduced, and meanwhile, the problem that the airbag is scrapped due to position deviation of heat-seal points is solved; after the heat-resisting layer is omitted, pollution to the environment is reduced, and production efficiency is greatly improved.
摘要翻译：本发明公开了一种无耐热层的充气气囊及其制造方法：所述充气气囊包括两个腔膜，所述两个腔膜的边界胶合在一起形成气密空间; 可充气气囊还包括设置在两个腔膜之间的两个阀膜; 第一热封线设置在阀膜的顶端; 阀膜和相邻的空腔膜通过第一热封线胶合在一起; 所述可充气气囊还包括第二热封线，所述第二热封线包括交替设置的断开区域和热压区域，在第二热封线的热压区中，两个阀膜和两个腔膜完全粘合在一起; 膨胀通道由第二热封线上方的两个空腔膜的部分形成; 袋体由第二热封线下方的两个腔膜的部分形成; 在第二热封线的断开区域中，在两个阀膜之间形成从充气通道通向袋体的进气口; 充气通道中设有充气口。根据本发明的可充气气囊，不需要现有技术的油墨耐热层的材料，降低了成本，同时解决了由于热封位置偏差而导致气囊报废的问题，省去了耐热层后，对环境的污染降低，生产效率大大提高。
