Description

Technical Field

[0001] This utility model relates to the field of aluminum foil packaging bag technology, specifically to an environmentally friendly food aluminum foil packaging bag. Background Technology

[0002] Aluminum foil packaging bags usually refer to aluminum-plastic composite vacuum packaging bags, which are bags made by combining multiple plastic films and then using a bag-making machine. They contain aluminum and have good oil resistance and softness. Because their surface does not absorb light and has a reflective luster, they meet the hygiene standards for food and pharmaceutical packaging and can also be used for food packaging.

[0003] Existing technologies, such as CN218453578U, describe a food packaging bag in which a reinforcing strip clamps and fixes the connection of the second protective strip, so that the unfolded state of the second protective strip is V-shaped, thereby ensuring that the packaging bag can be placed vertically for easy observation by the user.

[0004] However, the packaging bag still has some shortcomings in its use:

[0005] 1. This packaging bag is not easy to recycle after use. Because the packaging bag material is not environmentally friendly, it will cause some pollution to the environment if it is not properly disposed of after use, which does not meet the current social pursuit of green packaging.

[0006] 2. In addition, this type of packaging bag is made of only a single layer of material, making it susceptible to external impacts. It also lacks any external informational features, making it difficult to understand the details of the contents inside the bag, thus reducing its practicality. Utility Model Content
