For many EVA packaging manufacturers, the biggest costs are mainly two, one is the cost of labor, and the other is the material. There is not much that can be changed about labor costs. Either improve efficiency or reduce wages. It is easy to say that improving efficiency, but in actual operation, it involves upgrading equipment, strengthening management, etc., which increases costs from another aspect. Back to another point, that is, materials. Although the appearance looks the same, there are definitely differences in actual things. This does not mean that a certain material is not good. In fact, we have to look at the final use positioning. For example, materials can be divided into three types: A, B, and C, among which A is the best, B is the second best, and C is generally used as auxiliary materials. And here, each item can be further subdivided, such as A+, A-, etc. So when we ask for a lower price, we should first consider the purpose of the product, and then determine which material to use. The price of industrial products is not like that of handicrafts, and the price is not deceptive.
