金属包装涂料的使用,旨在较好地与食品接触,以防污染食品。首先要提及的是马口铁的镀锡率不断地在降低,甚至在某些情况下,锡的使用被完全取缔。一方面是因为锡的价格上涨,另一方面镀锡增加了马口铁制造的能源消耗。所以,涂料问题应深加研究,不管是内涂料,还是外涂料,都应适合食品的包装,具备应有的阻抗性能。涂料不应有任何毒性,涂料 The use of metal packaging coatings, designed to better contact with food to prevent contamination of food. The first thing to mention is that the tinplate rate of tinplate is constantly dropping, and even in some cases the use of tin is banned altogether. On the one hand because of the rising price of tin, on the other hand, tin increases the energy consumption of tinplate manufacture. Therefore, the paint problem should be further studied, whether it is within the paint, or outside the paint, should be suitable for food packaging, with the appropriate impedance performance. Paint should not have any toxicity, paint
