Aluminium Foil 8 Micron Big Roll Food Grade Specifications
The production of food aluminum foil bags should pay attention to the appropriate thickness, that is, it should not be too thick or too thin. A packaging bag that is too thin will not be able to protect the packaging. If the oily food is wrapped in the thin aluminum foil packaging bag, the oil stains will penetrate through the inside to the outside, which is equivalent to affecting its quality. In addition, food aluminum foil bags that are too thin are greatly affected by the environment and are easy to decompose under the sun and rain. Its thickness must be strictly controlled.
The first layer of the milk carton is an aluminum foil composite film, which is widely used in the packaging of food, chemicals, and military supplies. The milk carton is a kind of aseptic package made of aluminum foil and high-strength, heat-sealable plastic. It is made of composite film, which has barrier, mechanical and heat sealing properties.
Inside the milk box is aluminum foil.
There are generally the following types of milk packaging:
1. Glass bottle: traditional liquid milk packaging material, which can be used as a common packaging for home delivery channels sold by dairy companies in nearby cities.
2. Plastic: The packaging materials of pasteurized milk and ultra-high temperature instantaneously sterilized milk on the market are mostly made of plastic.
There is a layer of polyethylene film (PE film) in the innermost part of the aluminum foil package. The boiling temperature of ordinary water is not enough to dissolve and destroy the PE film, and it will not come into contact with food. Furthermore, the boiling temperature of water cannot reach the melting point of the PE film, and the milk will not touch the aluminum foil, so aluminum will not be detected. Aluminum material is also relatively stable. It is not a particularly active metal, so just by simply boiling this way, it will not undergo a chemical reaction and then enter the food.
