Product Description
The principle of Tetra Pak's aseptic packaging technology,
which is one of its core advantages, mainly high-temperature sterilization treatment and sealing processes in a sterile environment. First, before packaging, the product undergoes ultra-high temperature (UHT) sterilization or pasteurization. UHT typically heats the product to very high temperatures (e.g., 135°C - 150°C) for a short time (a few seconds), which rapidly kills most microorganisms in the product, including bacteria and spores, ensuring the product is commercially sterile before packaging.urization, on the other hand, is milder and mainly targets products that are more sensitive to heat. It involves heating the product to a certain temperature (.g., 60°C - 90°C) for a period of time to kill harmful microorganisms while maximizing the retention of the product's nutrients and. Next, in a sterile environment, the sterilized product is quickly filled into Tetra Pak materials and sealed. Creating a sterile environment is crucial, and Tet Pak equipment employs a series of advanced technologies and measures to achieve this. For instance, it uses efficient air filtration systems to strictly filter the air entering the packaging area removing dust particles and microorganisms to ensure the cleanliness of the packaging environment. Additionally, regular cleaning and disinfection of key components of the packaging equipment are conducted to the growth and residue of microorganisms on the equipment surface, avoiding secondary contamination of the product. During the sealing process, Tetra Pak uses advanced heat sealing technology tightly bond the layers of the packaging material together, forming a complete sealed package. For example, at the cross-seal and longitudinal seal areas, the heating temperature pressure, and time are precisely controlled to melt and firmly adhere the polyethylene plastic layers together, ensuring the seal meets high standards. This combination of high- sterilization and sealing in a sterile environment effectively prevents microbial recontamination after packaging, allowing the product to be stored at room temperature for extended periods without the need preservatives. This ensures the quality and safety of the product while meeting consumers' demands for convenient and fresh food products
