Abstract
The utility model is a composite membrane for making the intravenous transfusion medicine container bag. The cross section of the composite membrane includes the following sequentially ranging from the inner layer contacting the transfusion medicine to the outer layer contacting the air: polypropylene, ethylene copolymer, metallocene ethylene, the first sticking layer, ethylene-thenol copolymer, the second sticking layer and copolyester. The total thickness of the seven layers is 170mum-211mum. The intravenous transfusion medicine container bag made of the utility model not only has no side effects for the transfusion medicine, insulating against the steam, oxygen and nitrogen, but also can be sterilized by the moist heat at121 Celsius system or sterilized by the gamma ray. The invention has excellent practicability and flexibility in a wide temperature range from - 40 Celsius system to 121 Celsius system.
