Steel drums Its application although only more than 100 years of history, but with the development of modern steel industry, to provide a large number of agricultural and industrial sectors of steel, become the basis for the modernization of the departments, widely used in industrial products packaging, transport packaging and sales packaging, steel barrels become one of the main volume. At present, in various countries, Japan and Europe, about 14% of steel, second only to low and plastic packaging, accounting for the third, and the United States packaging consumption of steel more than plastic, about the second place. China's steel accounted for about 8% of the total, second only to plastic. In a variety of packaging technology with the rapid development of today, new and constantly emerging, competition is very fierce, steel barrels in some aspects of the application has been partially replaced by plastic or composite materials, but because the steel has a very good comprehensive performance, and the resources are extremely rich, so the steel still maintain vitality, the application of more diverse forms. Especially in the field of composites, it has been found that the successful application of the main barrier material layer in composites, such as the gold-plated composite film, is a good proof.
