Most of them use recycled materials, mixed with a small amount of new materials, and a certain amount of talc powder, to produce the usual lunch boxes. The mixing of recycled materials and new materials is a common practice in foamed tableware enterprises, and the proportion of recycled materials is higher than that of new materials. Some factories import industrial plastic waste foam abroad, process and extract it, produce polyvinyl ethylene foam particles (that is, recycled materials), and then sell these particles to foamed tableware factories as raw materials.
