In order to prolong the shelf life of foods, new packaging technologies are continuously developed, such as active packaging, anti-mold packaging, moisture-proof packaging, anti-fog packaging, anti-static packaging, selective breathable packaging, non-slip packaging, cushioning packaging, laminated plastic bags and other new types of food For packaging bags, these new technologies are widely used in developed countries, but China’s applications are not common, and some methods are still blank. The application of these advanced technologies can significantly improve the protective function of packaging.

In order to meet the needs of food processing technology, a variety of laminated plastic bags and new packaging equipment have been developed, such as vacuum packaging machines, vacuum inflatable packaging machines, heat shrink packaging machines, blister packaging machines, skin packaging machines, and sheet materials. Thermoforming equipment, liquid filling machine, forming/filling/sealing packaging machine, complete aseptic packaging equipment, etc. According to the selected packaging materials and packaging technology, the selection or design of packaging machinery that matches the food processing technology and production capacity is the guarantee of successful packaging.

The decoration design of laminated plastic bags should conform to the hobbies and habits of consumers and consumers in the exporting country. The pattern design is better coordinated with the contents. The trademark should be in an obvious position, and the text description should meet the food requirements. The description of the product should be true. Trademarks should be catchy, easy to understand, easy to circulate, and can play a wide publicity role. The packaging design of branded goods should be brand-conscious. Some product packaging is easy to change, which affects sales. For example, China’s Laoliutiao vinegar has a good reputation in Japan and Southeast Asia. The packaging is suspicious. Therefore, a product should be packaged scientifically and cannot be easily changed.

Laminated plastic bags have become a part of our lives. The above is a simple interpretation of the packaging technology requirements of laminated plastic bags. I hope everyone can have a basic understanding.
