Abstract

The invention belongs to the technical field of medicinal polymer packaging, and particularly relates to a breathing bag convenient to take. The breathing bag comprises a breathing bag body, the breathing bag body is composed of a paper surface and a film surface, the film surface is a polyethylene film, the paper surface is Tyvek paper, the three side edges of the paper surface and the three side edges of the film surface are correspondingly welded to form a bag-shaped structure with an opening in one side, and the length of the film surface at the bag opening is larger than that of the paper surface. The HDPE can provide good temperature resistance, mechanical property and barrier property, the LLDPE can provide good toughness and puncture resistance, the polyethylene film prepared from the two materials has excellent temperature resistance and puncture resistance, the length of the polyethylene film at the bag opening is larger than that of Tyvek paper, and the problems that the opening of a breathing bag is generally flat, and the bag opening is not flat are solved. The problem that the labor intensity is reduced, the production efficiency is improved, and the opening strength can be greatly improved at the same time is solved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical polymer packaging, and in particular relates to an easy-to-take breathing bag. Background technique [0002] Breathing bags are mainly used for packaging and sterilization of disposable rubber stoppers, disposable aluminum caps, sterile clothing, interface ring covers, filter elements, sealing rings, filling needles, silicone tubes, medical devices, and syringe components. The working principle of the breathing bags currently on the market is: the paper surface allows steam or sterilizing agents to enter and exit, but bacteria cannot pass through. During sterilization, the microorganisms in the bag are killed, and the sterile state of the bag can also be maintained after sterilization. However, there is a problem that the opening is generally flat, which will cause inconvenience for the operator to take it, and indirectly affect the production efficiency. Contents of the invention [000...
