What is the difference between the aluminum foil bag and aluminum foil bag?Today to share with you the aluminum foil bag and aluminized bag and identify the difference between a method.
Although has the aluminum aluminized bag and aluminum foil bag, but the aluminum foil bag is made of pure aluminum tablet, and aluminium bag it is under high temperature and vacuum, the high purity aluminum evenly on the best plastic.Aluminum is used in the aluminum foil bag aluminized bag.
Production cost of aluminum foil bag than aluminized bag production cost is high, and the production process has a significant difference between the two.In terms of performance through compound aluminum foil bag is aluminum and other metal materials, so the aluminum foil bag with good with good barrier property, heat sealing, shading, high temperature resistant, good low temperature resistance, oil resistance, the sex, avirulent insipidity, softness, etc, is more suitable for pumping air into vacuum state, suitable for food (such as rice, meat products and cooked food, etc.), electronics, circuit boards, electronic products, cable, etc.), precision equipment, and other packaging.Aluminium bag just the metal aluminum coating on other materials, aluminum plays the role of the more shading and decorative function, the other properties of the material is not very bag promotion effect, is suitable for the tea packing, electronic components.
That how to distinguish aluminized bag and aluminum foil bag?
Look, a visual identification method is in the bag in the face of the light or the sun, can see light through the bag is coated with aluminum foil, invisible is pure aluminum foil.Aluminum foil bag is not transparent appearance, a silvery white, can the luster.The brightness of the aluminum foil compared with aluminum plating is a bit weak, so the aluminum foil reflective good sex less than aluminum plating film, aluminium bag can reflect figure, except extinction film aluminum plating.Extinction film plating aluminum and aluminum foil very approximate appearance.Can the bag mouth, through the light bag, aluminum foil bag inside not pervious to light, pervious to light is aluminized bag.
Touch, aluminum foil bags of grip and crisp thick hard, heavy, feel of aluminized bag than aluminum foil bag is light and soft.Because pure aluminium bag is soft material, has a certain range, and aluminium bag is brittle.We can put the aluminum foil bag and aluminum plating folded, aluminum foil bag is easy to fold out dead plait mark aluminized bag won't fold into dead plait, and will rebound soon.Can also pull the aluminum foil bag and aluminized bag, aluminum foil bag pulling after coalescence is not easy to rebound, aluminum layer will appear rupture.Will soon after plating aluminium bag pulling NiuJieChu will play out, aluminum layer there would be no obvious cracks.
Fire, fire won't burn, aluminum foil with aluminum layer will rollback, the aluminum foil packing will leave after burn gray aluminum slag.Aluminum plating film can appear different plastic film when fire burning, no residual aluminum slag.
Above is yu the packing with aluminum foil bag, aluminum plating bag production experience for many years for the difference between these two kinds of material and to identify the method.Aluminum foil and aluminum plating play an important role in the packing bag production, in the food packaging bags, clothing bags, electronic packaging bags, cosmetic bags, etc are useful.
