With 6-layer packaging, each layer will have its own characteristics, taking on important functions in the composition of the packaging, including:

• The first layer: The innermost layer - is the surface in direct contact with the product. This layer is made of polyethylene to avoid impact by outside materials.
• 2nd layer: This layer is also manufactured from polyethylene, which is responsible for connecting the first layer to the third layer.
• 3rd layer: This is the aluminum layer, which acts as a barrier against harmful agents from the outside such as air, light.

Advantages of 6-layer paper packaging

Compared to other types of paper packaging produced more than a decade ago, current 6-layer paper packaging has 20% more rigidity than previous types of packaging.
 
The 6-layer cardboard box also uses aluminum foil to help store products at normal temperatures for extended periods of time. This is a thin layer of aluminum that is only 0.0063 mm thick, which is 10 times thinner than the thickness of a hair. Therefore, although composed of 6 layers, but this type of paper packaging has the advantages of super light but very durable and tough.

Moreover, 6 layers of paper packaging are designed so that each layer has certain effects in protecting the food. Typically, 6-layer paper-box packaging is very popular in the production of canned milk, food and vitamin drinks. According to experts, the amount of vitamins in glass bottles will be reduced by more than 40% when illuminated within 12 hours, but with paper packaging, this vitamin has not decreased.

Thanks to the aforementioned properties, vitamins in milk such as vitamin B2, vitamin A, B6, B12, C and K retain their properties when they reach consumers.
 
When using 6-layer paper packaging, people not only aim to use it to preserve the amount of vitamins that exist in foods, but also to preserve foods from decomposing under sunlight.
