1, depending on the price of paper cups: the cost price of qualified paper cups is generally not less than 8 cents. However, some inferior paper cups can be sold for 30 cents each. Consumers should not neglect their health because they are cheap.

2, look at the color of the paper cup: the paper cup is not as white as possible. The appearance color of qualified products produced by non-recycled paper should be yellowish. Inferior paper products are mostly pure white, and there will be a feeling of fine powder when touched by hand. This is because many unqualified manufacturers now use recycled paper as raw material to produce paper cups. In the process of making paper cups from recycled paper, in order to increase the brightness of paper and make buyers feel comfortable, manufacturers often add a lot of whitening agents to achieve a pure white "visual" effect.

3, smell the smell of paper cups: qualified paper cups are tasteless, can not smell strange smell, unqualified will have a smell similar to ink.

Therefore, when buying, you still have to choose regular manufacturers, such as Shobao and Miaojie. I hope it is useful to everyone.
