In industrial packaging flexible foil bag is the best proof packaging ocean, compared to shielding bags, vacuum bag, aluminum bags, aluminum foil bags of all of these products have the function of moisture-proof, good shielding effect, vacuum plus, dark air barrier, moisture and other effects. Foil bag manufacturing process is simple and complicated, the overall production process: aluminum ingot smelting - casting - cold rolling - intermediate annealing - cold - foil stock - roughing - in tie - precision rolling (doublet) - slitting - aluminum finish annealing - Compound - bag - foil bag finished - packaging. In this process, the wool is from the beginning to the machined aluminum foil prime the whole process, and then the composite bag. Which can be done inside and outside the resistance value: 108-1011 ohms. Aluminum bags, aluminum foil bags are a composite of the bag. So pure plated aluminum foil bags and bags of what is the difference? Their differences are as follows: First, from the material, said aluminum is aluminum bags, high-purity aluminum bags doped composites. Second, from a cost that is higher than the price of aluminum bags aluminum bags. Third, from the performance that aluminum bags moisture, the cooling effect is better than aluminum bags. Totally dark aluminum bags, aluminum bags are shading effect. Fourth, from the use of speaking, more suitable for vacuum aluminum bags, moisture-proof packaging for export loading cooked, meat, aluminum bags suitable for loading tea, powder, and other electronic components. Fifth, the bag facing the light or sunlight, can see light through the bag is plated aluminum foil, invisible is pure aluminum foil. Six, aluminum bags are soft material, a certain degree of elongation, and aluminum bags are brittle.
