Vacuum bags are mainly used to package perishable foods in cold chain logistics, such as meat, seafood, fruits and vegetables. By removing oxygen from the packaging, vacuum bags can create a low-oxygen or even oxygen-free environment, thereby slowing down the oxidation reaction and microbial growth of food and extending the shelf life of food.
The preservation effect of vacuum bags is mainly reflected in two aspects: first, by reducing oxygen contact, inhibiting the reproduction of microorganisms in food and slowing down food spoilage; second, by maintaining a low humidity environment in the package, reducing the evaporation of food water and keeping the food fresh. Taste and quality.
In cold chain logistics, the use of vacuum bags can significantly reduce food loss rate. Due to the preservation effect of vacuum bags, food can remain fresher longer during transportation and storage, thus reducing losses due to spoilage.
The use of vacuum bags can also ensure the quality of food. By removing oxygen, vacuum bags can reduce the contact of food with oxygen and prevent food from changing color and taste due to oxidation. At the same time, vacuum bags can also prevent food from being squeezed and impacted during transportation and protect the integrity of the food.
The application of vacuum bags in cold chain logistics also reflects environmental protection and economy. Compared with traditional cold chain logistics packaging methods, vacuum bags can reduce the waste of packaging materials and reduce packaging costs. At the same time, the reusability of vacuum bags also improves their environmental performance.
As consumers' requirements for food freshness and quality increase, the demand for the application of vacuum bags in cold chain logistics is also increasing. In the future, with the advancement of technology and the reduction of costs, vacuum bags are expected to be more widely used in the field of cold chain logistics.
Vacuum bags have broad application prospects and significant preservation effects in cold chain logistics. By reducing oxygen contact and maintaining a low humidity environment, vacuum bags can significantly extend the shelf life of food, reduce loss rate, ensure food quality, and reflect environmental protection and economy.
