[0030] I reduce the plastic deformation of corrugated cardboard through correct selection and application of corrugated cardboard
[0031] 1. Reasonable selection of corrugated cardboard
[0032] The quality of corrugated cardboard is the prerequisite for affecting the plastic deformation of corrugated cardboard. Since the peeling tension of the ink and the blanket on the paper surface is very large at the moment of separation in offset printing, it often causes the phenomenon of paper powdering and hair loss. High tensile strength, uniform texture of printing surface paper. The present invention selects the unit quality control of miniature corrugated cardboard at 380g / m 2 ~440g / m 2 , the material used is 185g / m 2 Recoat white cow card +90g / m 2 Corrugated base paper+140g / m 2 White cow card.
