The significance and use of bags in sterile boxes.bag in box for juice

The packaging requirements for sterile injection powders such as antibiotics are very strict, and no physical or chemical reactions between the packaging and the drug are allowed, and no impurities, including bacteria, are allowed to be brought in. For a long time, glass bottles or aluminum drums have been used for packaging of such substances, but there are problems with fragile packaging, difficult recycling, and high costs. The emergence of polyethylene sterile bags undoubtedly solves the packaging problem of sterile injection powder mentioned above.

Sterile bags are widely used for the transportation and temporary storage of sterile solid raw materials, sterile pharmaceutical excipients, sterile preparations, and other products due to their sterile, non-toxic, excellent low-temperature resistance, good chemical stability, and electrical insulation properties, as well as the transit packaging of sterile rubber stoppers from cleaning to filling lines. In addition, in the food industry, sterile bags can also be combined with cardboard and aluminum foil to form packaging containers for food. The weight of sterile bags accounts for about 20% of the entire packaging, mainly preventing liquid leakage and microbial invasion.

It is necessary for food packaging bags to adopt aseptic packaging technology. Due to the continuous contamination of various microorganisms during production, packaging, transportation, and storage, the items carry a large variety of microorganisms. Although sterilization techniques such as chemical agents, controlled atmosphere, high temperature, and low temperature can be used for sterilization. However, sterilization alone is not enough, as many items cannot be kept in a sterilization environment all the time, especially for certain foods. Therefore, sterile packaging technology is widely used in food packaging. The so-called aseptic packaging technology is a packaging technology that involves filling and sealing in a sterile environment when the packaging, packaging containers or materials, and packaging auxiliary equipment are sterile. The main research object of sterile packaging technology is the packaging of food and beverages, followed by the packaging of heat sensitive products such as pharmaceuticals.
