According to the processing performance and service performance of the paper cup, the paper cup base paper must meet the following technical requirements:
1. Strong water resistance
The paper cup is made without water seepage and leakage
2. Easy processing formability
When making paper cups, in order to avoid paper jam and wrinkling during the production process, and the formed paper cup is not easy to deform, it is required that the base paper of the paper cup has high stiffness, good flatness, appropriate loose thickness, and is easy to process and form.
3. Paper surface fineness
It is required to control the surface roughness value of the base paper to be printed or coated PE to meet the surface fineness required by the surface printing of the paper cup.
