(2) Technical requirements
According to the processing performance and service performance of the paper cup, the paper cup base paper must have the following technical requirements.
① High water resistance
The printed paper cup is required to be free of water seepage and leakage, so the paper cup base paper is required to have high water resistance.
② Easy to process
When making paper cups, in order to avoid paper jamming and wrinkling during the manufacturing process and prevent the deformation of the paper cups after molding, it is required that the stiffness of the paper cup base paper should be high, the flatness should be good, the printing process should be good, the density and thickness should be moderate, and it is easy to process and shape.
