This time, I will focus on some special advantages of aluminum foil bags in food packaging. At present, aluminum foil bags are widely used in food, medicine, clothing and other fields. For food, the use of aluminum foil bags is closely related to people's health. Among the many food packaging materials, the use of aluminum foil bags can make the food packaging appearance beautiful and pleasant on the one hand, on the other hand, it mainly guarantees quality, ensures food safety, and makes it easy to use and preserve. Therefore, the performance of the food aluminum foil bag material itself, the production design, the production process, and the environmental protection are put forward higher requirements, and the aluminum foil bag is developed in the direction of high barrier property, permeability, thin-film, and environmental protection.
First, for processed foods requiring high barrier protection, aluminum foil bags are generally required to have more than one layer of high barrier material. For food, the use of high-barrier aluminum foil bags meets the demand for high oxygen barrier and oil resistance of fatty foods. It not only protects food but also reduces the amount of plastic when packaging the same amount of food.
Secondly, the recent application and development of multi-layer coextrusion technology have changed the product structure of functional films and containers, making aluminum foil bags to be thinner and lighter, to reduce packaging functionality as much as possible. The amount of garbage generated.
Third, with the emergence of environmental problems such as the reduction of the ozone layer, global warming, and extreme ice capacity, people's awareness of environmental protection is also strengthening. The previous "white garbage" can no longer meet people's perception of low carbon and environmental protection concepts. With the need, aluminum foil bags can only be developed in the direction of environmental protection.
