Product Description
one of its core advantages, mainly includes hightemperature sterilization treatment and sealing processes in a sterile environment. First, before packaging, the product undergoes ultra-high temperature (UHT) sterilization or pastization. UHT typically heats the product to very high temperatures (e.g., 135°C - 150°C) for a very short (a few seconds), which rapidly kills most microorganisms in the product, including bacteria and spores, ensuring the product is commercially sterile before packaging. Pasteur, 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 (e.g 60°C - 90°C) for a period of time to kill harmful microorganisms while maximizing the retention of the product's nutrients and flavor. , in a sterile environment, the sterilized product is quickly filled into Tetra Pak materials and sealed. Creating a sterile environment is crucial, and Tetra Pak 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 particles and microorganisms to ensure the cleanliness of the packaging environment. Additionally, regular cleaning and disinfection of key components of the packaging equipment prevent the growth and residue microorganisms on the equipment surface, avoiding secondary contamination of the product. During the sealing process, Tetra Pak uses advanced heat sealing technology to tightly bond the layers the packaging material together, forming a complete seal. For example, at the cross-seal and longitudinal seal areas, precise control of heating temperature, pressure, and parameters melts the polyethylene plastic layers and securely bonds them together, ensuring the seal meets high standards. This combination of high-temperature sterilization and sealing in sterile environment effectively prevents microbial recontamination after packaging, allowing the product to be stored at room temperature for extended periods without the need for preservatives. This ensures quality and safety of the product while meeting consumer demands for convenient and fresh food products.
