How can I choose corrugated base paper and cardboard?
Quality matching. Generally should use quality grade similar corrugated base paper and cardboard to produce corrugated cardboard, such as A, B class box cardboard should try to choose grade a corrugated base paper; D, E class cardboard can choose C, D grade corrugated base paper. Corrugated cardboard made of high strength carton and low grade corrugated paper is easy to collapse and low flat strength. Improper collocation or quality may not meet the requirements of the contract, or cause waste of raw materials and unreasonable cost.
In order to make the corrugated board not only meet the quality requirements of the use, but also cost reasonable, it is necessary to correctly select corrugated base paper and cardboard.
Quantitative matching. The practice shows that the proportion of general carton and corrugated base paper is in the range of 2:1. If the corrugated paper cardboard box with respect to quantitative is too low, will cause the tooth shape of corrugated lamination change into rectangular shaped structures by arc, influence of corrugated board thickness and compressive strength and cushioning performance of corrugated paper; if too high too low and quantitative quantitative paperboard collocation, made of corrugated cardboard surface is not flat, obviously corrugated stripes, affect the appearance and printing effect.
