Many customers are confused about the thickness of the paper cup. Now the average manufacturer uses 210g-300g. For example, we usually use 248g and 268g and 300g for 9 ounces (250ML). The customer is placing an order. Before you must ask, there is another point. Some customers have their own samples on their own hands, thinking that this is the same. In fact, they are different. There are also manufacturers of paper base paper. The paper from each paper mill is different. The main performance is the whiteness, hardness and smoothness of the paper cup.

The thickness of the paper cup also refers to the stiffness of the paper cup. Many customers react to the thin paper and the paper is soft and hard. Here is the pulp of the original paper, the production process, and the weight of the paper. Now the paper used for the advertising cup is 248g, 268g, 298g.
