Plastic cans lumber trend

   We can say, think of is definitely Pepsi Cola, beer and beverage containers with metal as raw materials.

   When the cans were invented, is can cover the material itself is processed into a rivet, a coat and a riveted ring, with suitable notches and become a full tank cover. Can be said that can lay a solid foundation for cans and beverage industry development.

   At the beginning, out of consideration for the cost of the cost of steel cans (about $7/1000 less than the cost), steel cans in South America dominated the beverage packaging market. But with the improvement of environmental awareness. And resource recycling of packaging materials to replace the steel aluminum into account. Similarly, with the application of tension technology in the production of spray cans of aluminum type spray cans also occupy the market gradually.

   Although aluminum cans has the advantages of light weight, small volume, not easily broken, easy to carry, so people favour. But the scientists found that the content of aluminum beverage cans in 3 - 6 times higher than bottled drinks. This is because in the process of cans, inevitably some local protective coating without coating, or coating is too thin, the tank wall Aluminum Alloy and beverage contact. The aluminum can react with acid to produce elemental aluminum salt and alkali, and the reaction of meta aluminate. This will lead to a gradual increase in the aluminum content of the beverage. Cause damage to the human body because of excessive intake of aluminum.

   Then the plastic cans will appear, the plastic metal cans cans relatively more portable, but the permeability coefficient of oxygen and carbon monoxide is large, it will result in a chemical reaction between packing objects and packaging, packaging is also due to oxidation and make the taste change. But like PET and other new types of plastics, although there is no such shortcomings, but because of higher prices, limiting its development.
