8079 Aluminium Foil 7mic Flexible Packaging For The Chocolate Industry
Tinfoil or aluminum foil packaging chocolate is mainly used for sealing, moisture-proofing, and light-proofing, as well as heat preservation and heat insulation to a certain extent.
The aluminum film paper is not used for shaping after the chocolate is made. The thermal conductivity of metal is very good. If it is used as a mold, the plastic with good plasticity is better. Then why use aluminum film paper? The raw materials of chocolate are: cocoa mass and cocoa butter, granulated sugar, milk, etc., which are made by grinding cocoa beans. If the chocolate is exposed to direct light, the cocoa butter in it will react with moisture and oxygen in the air, resulting in the smell of chocolate There will be loss of both taste and taste, so there will be no chocolate aroma when peeling off the chocolate paper and delicious taste when you eat it. Aluminum foil paper is used to keep the chocolate delicious, and it also has the effect of preventing insects and bacteria.
Nowadays, there are generally two kinds of packaging, one is pure aluminum foil, and the other is metal-colored plastic texture packaging. The first is formed by rolling and stretching aluminum, and the second is made by heating aluminum to vaporize (aluminum melts at 660°C and vaporizes above 2000°C) and adheres to the film.. The second type is used in many It is used on the packaging of food products (Really a great invention, a simple coating can solve the problem of food preservation that cannot be directly exposed). I have asked how to form aluminum film, but it is not my specialty. I checked it and explained it briefly. A vacuum furnace is used to make aluminum foil film. Aluminum evaporates below to produce green aluminum atoms. Due to the presence of gas molecules, it is not easy to adhere to the substrate and will fall below or on both sides. At this time, a vacuum furnace is used to vacuum, the gas molecules are reduced, and a large number of aluminum atoms can be attached to the substrate to form an aluminum film.
