Division I Original No. Priority Abstracts The present invention relates to a method for manufacturing a breathable and transformable packaging bag, in particular to a method which can be sterilized with gases such as ethylene oxide. The method for manufacturing a medical packaging bag, which can be converted into a closed structure after sterilization, is characterized by adopting four kinds of packaging bag manufacturing methods which are first gas sterilized and can be converted into a closed structure after sterilization. Sterilized and sealed effect. The advantages of the present invention are simple and convenient, and are particularly suitable for medical personnel to use conveniently. Sovereignty Item 1. A method for manufacturing a breathable and convertible packaging bag, characterized by comprising the following steps: (1) manufacturing a breathable and transformable packaging bag comprising a barrier material portion (1) and a breathable material portion (2) Composition, one side of the packaging bag is the barrier material part (1), the other side of the packaging bag is more than one-half part of the barrier material part (1), less than one-half part is the breathable material part (2); (2) The packaged product is packed in a packaging bag for sealing, and ethylene oxide is injected from the gas permeable material part (2) after sealing to sterilize; (3) After the sterilization, the part (1) of the barrier material is along the gas permeable material part ( 2) Edge heat sealing, or converting the breathable material portion (2) into an air impermeable material.
