Dampfsperraluminiumfolie

Dampfsperraluminiumfolie have great high temperature resistance, Feuchtigkeitsbeständigkeit, und Barriereeigenschaften. Wegen seiner guten Barriereeigenschaften, Es kann effektiv auf Lebensmittelverpackungen angewendet werden, die eine Langzeitlagerung erfordern. Das Aluminiumfolienwalzwerk ist mit einem fortschrittlichen automatischen Dickenkontrollsystem und einem automatischen Formkontrollsystem ausgestattet, um eine genaue Kontrolle von Form und Dicke zu realisieren. Select high quality aluminum foil blank, strictly control the hydrogen content, nonmetal slag content and grain size to ensure the product quality from raw materials.

Compared with other packaging materials, aluminum foil has low moisture permeability, good moisture resistance, and at the same time has the advantages of safety, convenience and long shelf life. Although the thickness of Aluminiumfolie is reduced (less than 0.02mm), pinholes and as the thickness of the aluminum foil increases, its moisture-proof performance is still superior to plastic films without pinholes and other packaging materials. This is because the plastic polymer chains are far apart from each other and cannot prevent water vapor penetration. If the surface of aluminum foil is coated with resin or compounded with paper or plastic film, its moisture resistance is better.

When the thickness of Dampfsperre Aluminiumfolie is small to a certain extent, pinholes will inevitably appear. The minimum thickness of pinholes is generally considered to be 0.038mm. Due to the improvement of rolling technology and material, this thickness has been reduced to 0.025mm. The experiment also proved that the diameter of the vent hole is critical. When the diameter is less than 55m, oxygen and water vapor are not transmitted in the measurable range.
