Developed milk packaging adopts six-layer aluminum-plastic composite aseptic material

At present, developed countries generally use ultra-high temperature flash pasteurization (UHT) technology to package fresh milk: milk is heated to over 135°C, rapidly cooled to room temperature for only a few seconds, and then under a sealed aseptic condition, six layers of aluminum are used. Plastic composite sterile material filling and sealing box. UHT technology organically combines sterilization equipment and packaging materials. Compared with traditional methods of sterilization and filling, high temperatures can eliminate harmful microorganisms, and short-term sustained high-temperature treatment preserves the nutrients and taste of milk. The application of composite packaging materials is to prevent bacteria, light, and air from damaging the freshness of milk. Therefore, the milk can be stored for up to 9 months at room temperature. UHT milk has provided consumers with protection from the point of view of nutrition and safety, and is therefore more and more popular.
