From raw materials (paper) to products (formed paper cups, paper bowls), paper cup machines and paper bowls need three processes: printing, die-cutting, and forming. From paper lunch boxes, only two processes: die-cutting and forming.
The paper cup machine milk is fresh, elegant, hygienic, convenient and fashionable, giving people a refreshing feeling. It is used to package liquid milk or fermented milk abroad, especially in Japan and Southeast Asian countries. In China, it is a new form of packaging.
At present, with the exception of large-scale manufacturers who complete all the processes independently, most investors start out with outsourcing the two processes of printing and die-cutting. Firstly, investment can be reduced; secondly, the printing process is highly professional.
In order to make the cup look whiter due to the poor quality of the paper cup machine, some paper cup manufacturers add a large amount of fluorescent whitening agent. This fluorescent substance can mutate cells and become potentially carcinogenic once it enters the human body. factor. According to national regulations, phosphors are not allowed in food paper. Therefore, the paper cup is not as white as possible.
