The development of food composite bag packaging equipment tends to be multi-purpose and high-efficiency, and more and more attention is paid to speed and cost. The future development trend is that the equipment is smaller, more flexible and mobile, and tends to be multi-functional and flexible. And this trend is very beneficial to save production time and reduce costs, so what the food packaging industry is pursuing is a combined, simplified, and movable food packaging equipment. In terms of food packaging machinery automation, computer integrated manufacturing technology will be widely used in advanced food packaging systems.

When customizing food composite bags, pay attention to the following requirements, and make full preparations in the selection of materials. Because the packaging environment has changed, not all packaging bags can be used. Nowadays, the air quality is getting worse and worse, so packaging bags made of environmentally friendly materials are now the mainstream. Therefore, environmental protection and pollution-free materials should be selected for the packaging materials, because environmental protection can be used in food packaging. Because of environmental protection, the bag can be used in the market.

The total cost of food composite bag packaging materials and packaging system is reduced. The food packaging industry will reduce shipping costs by using lighter materials, shorten production time through the use of specially designed components and systems, and strive towards the goal of providing packaging operations with the least amount of materials. At present, the food packaging industry is paying attention to the rational use of materials and labor saving in the operation process, as well as the reduction of inventory and handling costs from the circulation link.

Food itself has certain nutrients and moisture, which are the basic conditions for the production and reproduction of bacteria, mold, yeast, etc. When the food is stored at a temperature suitable for their reproduction, it will cause the food to spoil. If the food is aseptically packaged or processed by high-temperature sterilization and refrigeration after packaging, it will prevent the occurrence of food spoilage and extend the shelf life of the food.

At the same time, the food itself has a certain amount of water. When the content of these water changes, it will cause the change or deterioration of the food flavor. If the corresponding moisture-proof packaging technology is adopted, the above phenomenon can be prevented, and the shelf life of the food can be effectively extended.

Furthermore, when food is circulated, when it is exposed to direct sunlight and light, and at high temperatures, it is easy to oxidize the food. Discoloration, taste change and other phenomena, such as the use of corresponding vacuum packaging, inflatable packaging and other technologies and corresponding packaging materials. It can also effectively extend the shelf life of packaged foods.
