The difference between sealed food packaging bags and packaged food

Packaging bags are the most widely used in food packaging. Many snack food packaging bags are used in aluminum foil bags, such as Zhou Hei Ya's duck feet, duck necks, betel nuts, and chicken feet. You go to the snack food area of ​​supermarkets and shopping malls and quickly find that aluminum foil bag packaging has already occupied half of the country. Why are aluminum foil bags so popular? How is it different?

One of the difference: excellent shading

This is the characteristic that only aluminum foil bags have among all food packaging bags. Keep the food away from direct light, which can improve the shelf-life of the packaging and keep the food's taste and fragrance. Like the aluminum foil bag's high and low temperature resistance, oil resistance, fragrance retention and high barrier, these capabilities can also be achieved and possessed by other composite packaging bags.

The second difference: beautiful metallic luster

This is also a characteristic unique to food packaging bags. The beautiful silver color makes it shine in the vacuum bag. Because the packaging bag will have wrinkles after being vacuumed. Color-printed complex patterns cannot be displayed perfectly, on the contrary, they may appear empty. The aluminum foil bag packaging, with its silver appearance, can play a good decorative role. In addition, the silver background color gives more space and inspiration to the design, allowing the designer's wild ideas to be fully displayed.
