Although the application of iron drums has only a hundred years of history, it has been developed rapidly and has a wide variety. It is widely used in industrial product packaging, shipping and packaging, and in the sale of packaging, mainly because the iron barrel has the following features:
1. The iron drum has excellent mechanical function and high strength. Therefore, the iron drum container can be made into a thin-walled, high-pressure-resistant and difficult-to-break packaging container. This makes the safety of the packaged product reliable and easy to store, transport, handle and use.
2. The processing function of the iron barrel is excellent, the processing technology is sophisticated, and it can be continuously and automatedly produced. The iron drum has good ductility and strength, and can be rolled into various thickness plates and foils. The plates can be stamped, rolled, stretched and welded to form different packaging containers with different shapes and sizes.
3. The iron bucket has excellent inductive protection. The water vapor transmission rate of steel is very low, completely opaque, and can effectively avoid the harmful effects of ultraviolet rays. Its gas barrier, moisture resistance, opacity and shelf life greatly exceed other types of plastics, paper and so on. Therefore, the iron barrel can adhere to the quality of the product for a long time, which is especially important for food packaging.
4, the iron barrel has a special metallic luster, and is also easy to print and decorate, so that the product looks luxurious and beautiful, beautiful and marketable.
5, iron barrels are rich in resources, energy consumption and cost are also relatively low. And it has repeatable recyclability, and it is ideal green in terms of environmental protection.
Iron drums have the above characteristics, but they also have shortcomings. Mainly: poor chemical stability, corrosion resistance is not as good as plastic and glass, especially ordinary steel is simply rusted. Therefore, the iron drum must be covered with a layer of anti-rust material on the outside to avoid the corrosion damage from the outside and the packaged object. Together with the harmful substances in the steel, the product should be contaminated. For example, the steel contains heavy metals to varying degrees. Merchants Pb, Sn, etc., these heavy metal ions can be used with product effects, especially food, not only contaminating food, but also these heavy metal ions are more harmful to the human body.www.fhpails.com
