Product Description
Analysis of the product characteristics of Tetra Pak. Dissection of the material composition of Tetra Pak. Tra Pak is mainly composed of multiple layers of materials including cardboard, aluminum foil, and polyethylene plastic. The cardboard serves as the basic structure, providing certain stiffness strength to the package, allowing it to maintain a stable shape during transportation and storage, and preventing deformation damage due to external pressure, thus providing effective physical protection for internal product. Meanwhile, cardboard is widely sourced and renewable, conforming to modern environmental protection concepts, helping to reduce environmental impact, and is one of the key for Tetra Pak to achieve sustainable development. The aluminum foil layer has excellent barrier properties, effectively blocking the intrusion of light, oxygen, and microorganisms. ultraviolet components in light may trigger oxidation of fats and decomposition of vitamins in food, leading to a decline in food quality and loss of nutrients; oxygen is a condition for the growth and reproduction of many microorganisms, and is also a key factor in food oxidation and spoilage; while microbial contamination directly threatens the safety and life of food. The presence of aluminum foil acts like a solid barrier, keeping these adverse factors at bay, greatly extending the shelf life of the product, ensuring the food remains fresh, nutritious, and safe for a longer period of time. For example, milk packaged in Tetra Pak can have a shelf life of several, which is a significant advantage in the field of food packaging. Polyethylene plastic plays several key roles in Tetra Pak. On one hand, it serves as inner layer material, directly contacting the food, with good chemical stability and safety, preventing chemical reactions between the food and the packaging material, ensuring that the food's taste and quality are not affected; on the other hand, polyethylene plastic has excellent waterproof properties, effectively preventing external moisture from penetrating into the interior of the package avoiding food dampness and spoilage. Additionally, at the sealing part of the package, polyethylene plastic achieves sealing by heating and melting, ensuring the package'sability, preventing air and microorganisms from entering the package through the seal, and further enhancing the overall protective performance of the package
