Currently, the international production of A large amount of tinplate metal material is used to make packaging containers, thus presenting a more specific need. The original tinplate materials are not considered for the production of packaging containers manufacturing special requirements, just very ordinary tin, so the production of tin cans for packaging supplies will now have a lot of unsuitable situation. In the development and production of special tinplate materials for packaging, Europe leads the world in the forefront of the countries. French steel group is currently the largest steel companies in Europe, its quality and production will not be second to Japan, and the overall production of technology and variety of improvements is difficult to match Japan. In recent years, France Steel first developed a special tinplate material for packaging and put it on the market, which also caused a revolution in various packaging industries.
The special tinplate needed to manufacture tinplate box packaging containers is an important direction for the development of the steel industry. French companies in recent years the development of packaging special tinplate material has been put into use in many areas of Europe, and accompanied by the trend of popularity. The main types of products are three-piece cans with tinplate and cosmetic cans with tinplate, closed lids and crown lids with tinplate, paint and chemical products using containers with tinplate, two-piece cans with tinplate, special-purpose packaging with tinplate and many other.
But in terms of the current production of tin can packaging in China, the tinplate materials used in China are mostly not distinguished by purpose, manufacturing packaging containers often have unstable quality and some of the more difficult to solve unexpected problems. If you can use special tinplate, the quality and quality problems affected by the use of materials can be perfectly solved. In fact, domestic packaging container products with quality problems, scrap problems, to a large extent, are related to the use of materials. The use of specialized tinplate in European countries also happens to illustrate this point.
Packaging special tinplate has special characteristics
< ;span style="font-size: 16px;"> Mr. Giraldo, who is engaged in the research of special tinplate for packaging in France, came to China not long ago, and after fully investigating and understanding the survival situation of tin can production factories in China, he thought that the tinplate for packaging must no longer use ordinary tinplate, otherwise, it will not only cause the alarm of waste, but also difficult for enterprises to obtain profits to maintain the overall survival and development.
Depending on the requirements for packaging use in various industries, there are different needs for the thickness, tin plating amount, and mechanical properties associated with tinplate materials. At present, in Europe used to make three-piece tinplate material thickness are 0.13-0.2 mm, France in this material research and application has been very successful, not only to save steel, reduce production costs, and production of products in all aspects of the requirements (such as mechanical strength, etc.) will not be reduced. At present, the overall development trend of tinplate materials for metal packaging:
(1) Reduce the thickness of the material used;
(2) improve the mechanical properties of the material at the time of production. Packaging tinplate the most important indicators generally refers to the plastic deformation index and welding performance index of the material. In general, the material T610 is used to make beverage cans, T6T67 material is used to make food canning jars, the bottom and cover of the cans also use special steel, can materials 520 and 580, this material is easy to weld.
