I want to know some general information about the EVA foam engraving industry, but I find that it is not easy to find such information. At present, I can only find general information about packaging-related companies. It makes sense to think about it. After all, foam engraving is an industry that is subdivided and then subdivided. The scale of the company is indeed too small compared to those factories that produce raw materials. This can only be regarded as a very small department in this raw material factory. Of course, because of this, they are usually not motivated enough to improve production.
