During aseptic processing, a sterilized package is filled with a commercially sterile food product and sealed within the confines of a hygienic environment. In Aseptic bag we have polyethylene particles as raw material, blown film, cutting, heat sealing, vacuum packaging, sterilization in a clean environment.

Several materials are layered together to provide the level of protection required for aseptic packaging standards, including:

Polyethyleneis used as a barrier on the inner and outer sides of aseptic packaging. These layers protect against moisture entering or exiting the container.
Film foil helps preserve the product by keeping light and oxygen out.

Aseptic bags are widely used in aseptic solid raw materials, sterile pharmaceutical auxiliary materials, sterile preparations and the like due to their sterility, non-toxicity, excellent low-temperature resistant performance, good chemical stability and electrical insulation properties. Transit and temporary storage of pharmaceuticals and chemical products. in the food industry, aseptic packaging bags are divided into high volume aluminum-plastic composite aseptic bags (5 ~ 200L) and low volume co-extruded film aseptic pouches (200 ~ 500ml); aseptic bags can also be used with cardboard The paper-based multi-material composite packaging containers, which consist of aluminum foil and food, contain about 20% of the entire packaging weight, and mainly block the effects of liquid leakage and microbial invasion. They are perfect packaging materials for juices, jams, dairy products and other foods.

Aseptic bags production is carried out in a clean room, through a complex sterilization process to achieve the strict requirements of aseptic packaging. Compared with ordinary bags, aseptic bags can retain the nutrients of the food, it helps the food to maintain more color, texture, mouthfeel, and consume less energy, stored at room temperature for longer, and Sterility-required products provide a safe and stable storage environment.
