In which way does composite aluminum foil achieves heat insulation?
The features: the first aluminum foil layer(1), the second aluminum foil layer(3)and plastic film layer (2) bond together. Plastic film(2) is between the first aluminum foil layer(1)and the second aluminum foil layer(3). This utility model composite aluminum has good strength,toughness,shock resistance and high ability of acidproof and alkaliproof. It is also with property of gas insulation,thermal insulation,ultraviolet ray insulation and radiation protection.The outside two layers of composite aluminum foil is aluminum foil, which appearence is like the current monolayer aluminum foil and with the same property with it. It can save the material costs and is the ideal substitute of monolayer aluminum foil.
