Research and application progress of cold-chain logistics packaging technology of fresh agricultural products

Cold chain logistics packaging technology is crucial for the operation of perishable food chains （such as meat, fish, dairy products, fruit and vegetable products） and certain products in the pharmaceutical industry （such as vaccines, biopharmaceuticals, and blood products）. In the future, the cold chain logistics packaging of fresh agricultural products will tend towards high-performance, environmentally friendly, and digital development. The article reviews the packaging technologies used in the cold chain logistics of fresh agricultural products in recent years. Analyzes the characteristics, use value, application scope, technical advantages and disadvantages of different packaging materials, and analyzes the potential cold chain logistics packaging technologies and materials for agricultural products, as well as the composite use of different packaging technologies, in order to explore the optimal packaging for different fresh agricultural products. Develop corresponding cold chain logistics packaging tailored to different fresh agricultural products, gradually abandoning packaging technologies with low recycling rates and poor performance. By increasing the frequency of recycling and reducing the cost of using high-performance materials, to reduce losses in the cold chain logistics of fresh agricultural products and achieve the goal of environmental friendliness.
