The overall performance of the aluminum foil
1, the mechanical residences
The mechanical properties of the foil consisting of tensile strength, elongation, rupture electricity and so on. Mechanical houses of aluminum foil is specially decided with the aid of the thickness, the national preferred GB / T3198-2003 "aluminum and aluminum foil(commercial aluminum foil)" within the longitudinal course of the mechanical properties of aluminum foil made corresponding provisions.
Average, the best of mild aluminum, ductile, skinny, small mass per unit place. However low energy, smooth tear, easy to break while folded, produces perforations, it is usually no longer used entirely for packaging merchandise. In lots of cases, and different plastic film and paper composite, in order to overcome its shortcomings.
2, high barrier
Aluminum foil having water, water vapor, fiber, taste has a high barrier, and from the surroundings, temperature, for that reason keeping taste typically used in packaging, moisture-evidence packaging to prevent the absorption of moisture contents of the bundle, and unstable oxidation deterioration. Specifically appropriate for high-temperature cooking meals packaging sterilization.
3, corrosion resistance
Herbal floor oxide movie is formed of aluminum foil, to shape an oxide movie might also in addition prevent any further oxidation, and therefore, an aluminum foil having sure durability and air resistance. However it isn't always acid corrosion, therefore, the contents of the bundle have a high acidic or alkaline, frequently covered with PE and different included fabric or covered on its surface, on the way to improve its corrosion resistance.(Introduces the overall performance of the aluminum foil(aluminum foil thickness)
Four, warmness resistance, low temperature performance
Aluminum foil high and occasional temperature consistent state, the temperature -seventy three-371 ℃ with out swelling and shrinkage deformation, but also has right thermal conductivity, thermal conductivity up to 55%. Consequently, both may be used for high-temperature cooking or different thermal processing, but additionally for frozen packaging.(aluminum foil roll)
5, shading overall performance
Aluminum foil (aluminum foil fee)protecting with suitable overall performance, the reflection fee up to 95%, at the same time as the advent of silver-white metal luster, decorated with the aid of the surface printing may additionally showcase accurate packaging decoration effect, it is also a excessive-grade aluminum foil packaging substances.
