The difference between pure aluminum foil bags and aluminum foil bags
Today we will share with you the pure aluminum foil bag and aluminum foil bag and the different methods for identifying both.
There have the pure aluminum foil bag and aluminum foil bags. The pure aluminum foil bag is made of pure aluminum tablets. Still, in aluminum foil bag which is under high temperature and vacuum, the high-purity aluminum is evenly on the best plastic. Aluminum is used in the pure aluminum foil bag.
The production cost of pure aluminum foil bags is higher than aluminum foil bags, and the production process has a significant difference between both them. In terms of performance through, compound pure aluminum foil bag is aluminum and other metal materials, so the pure aluminum foil bag with good barrier properties, heat sealing, shading, high temperature resistant, good low-temperature resistance, oil resistance, sex, avirulent insipidity, and softness, etc., which 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, and cable, etc.), precision equipment, and another packaging. Aluminum foil bag is just the metal aluminum coating on other materials, and aluminum plays the role of the shading and decorative function. The other properties of the material are not so good, which is suitable for tea packing and electronic components.
That how to distinguish pure aluminum foil bag and aluminum foil bag?
Look, a visual identification method is through the light of the sun, can see light through the bag is coated with aluminum foil bag, invisible is pure aluminum foil bag. Pure aluminum foil bag is not transparent on the appearance, a silvery white, can the luster.The brightness of the pure aluminum foil bag compared with aluminum foil bag,which is a bit weak, so the aluminum foil bag reflective good sex less than pure aluminum foil bag, aluminum foil bag can reflect figure, except extinction film aluminum plating.The appearance of aluminum foil film and pure aluminum foil are very approximate. Through the light, the inside of pure aluminum foil bag is not previous to light, but aluminum foil bag can be.
Touch, the grip of aluminum foil bag is thick hard, heavy, which is light and soft than pure aluminum foil bag. Because pure aluminium foil is soft material, which has a certain range, but aluminum bag is brittle. We can fold the pure aluminum foil bag and aluminum foil bag, pure aluminum foil bag is easy to fold out with the mark of dead plait but aluminum foil bag can’t be folded into dead plait and will rebound soon.
Both pure aluminum foil bag and aluminum foil bag can also be pulled as well, pure aluminum foil bag is not easy to rebound after pulling and the aluminum layer will appear rupture, but there will no have obvious cracks after being pulled the aluminum foil bag.
Fire, the layer of pure aluminum foil will rollback and will leave gray aluminum slag after being burned. But aluminum foil will appear different plastic film and have no residual aluminum slag leave here after being burned.
Above through the production experience with many years of pure aluminum foil bag and aluminum foil bag to let you know the difference between 2 kinds of different materials and the method of identification.
Pure aluminum foil film and aluminum foil film play an important role in the production of packaging bags, which are useful for the food packaging bags, clothing bags, electronic packaging bags and cosmetic bags, etc.
Both pure aluminum foil bags and aluminum foil bags are able to be produced by our factory. Please kindly send us more details for checking prices for reference.
