For a long time, sterile powder injections such as antibiotics have been packaged in glass bottles or aluminum barrels, but there are some problems such as fragile packaging, difficult recycling and high cost, and the emergence of medical bags just solves the above packaging problems. Medical polyethylene bags first appeared in 1992. It was developed by Shijiazhuang Yucai Medical Packaging Materials Co., Ltd. and Huabei Pharmaceutical Co., Ltd. through a large number of experiments when developing antibiotic aseptic powder packaging. It is named medical low density polyethylene film bag. The emergence of medical bags filled the gap in China and initiated the packaging revolution of antibiotic powder injection. The following year, Hebei Medical Bureau issued the first medicine bag production license for Shijiazhuang Yucai. 1994 also issued the quality standard of medical polyethylene bags. Since then, from 1995 to 2003, the state has gradually improved the supervision of the production of medical bags, and the supervision of medical bags has changed from the registration certificate of medical low-density polyethylene bags to the first-class registration certificate of medical low-density polyethylene bags in direct contact with drugs. Medicine bags are gradually recognized by pharmaceutical companies because of their stable performance, simplicity and low price.
Therefore, in the market of medical packaging materials, manufacturers of medical bags have mushroomed.
