Aluminum, as a kind of white light metal with rich resources, is second only to steel in output, and its application in packaging industry ranks first in non-ferrous metals. What are the characteristics of aluminum packaging-Aluminum plate is usually used as can making material or cover making material.
Therefore, aluminum packaging containers can be made into thin-walled, high compressive strength, not easy to damage packaging containers. In this way, the safety of packaging products is guaranteed reliably, and it is easy to store, carry, transport, load and unload and use.
With mature processing technology and continuous and automatic production, aluminum packaging materials have good ductility and strength, and can be rolled into various thickness plates and foils. The plates can be pressed, rolled, stretched and welded to make packaging containers with different shapes and sizes; Foil can be compounded with plastics and other materials, so metal can give full play to its excellent and comprehensive protection performance in various forms.
The water vapor transmission rate of aluminum is very low and completely opaque, which can effectively avoid the harmful effects of ultraviolet rays. Its gas resistance, moisture resistance, shading and fragrance retention are much better than other types of packaging materials such as plastic, paper and so on. Therefore, it can maintain the quality of goods for a long time, and has a long shelf life, which is particularly important for food packaging.
It is also easy to print and decorate, so that the appearance of the goods is rich and beautiful, and the goods are beautiful and marketable. In addition, aluminum foil is an ideal trademark material.
In terms of environmental protection, it is an ideal green packaging material. As a packaging material, aluminum is usually made into aluminum plate, aluminum block, aluminum foil and aluminum film. Aluminum plate is usually used as can making material or cover making material; The aluminum block is used to make cans for extrusion forming and thinning drawing forming; Aluminum foil is generally used for moisture-proof inner packaging, composite materials and flexible packaging.
