Failure analysis in the production process of paper straw manufacturers:
1. The design of cardboard layers is unreasonable
The unreasonable design of the number of cardboard layers will lead to an increase in the breakage rate of paper straws. Therefore, the number of cardboard layers used in paper straws should be considered according to the weight, nature, stacking height, storage and transportation conditions, storage time and other factors of the packaged goods.
2, the bonding strength is poor
To determine whether the adhesion of the paper straw is good, as long as you tear the adhesive surface by hand, if you find that the original paper surface is peeled, it means that the paper is glued well; If it is found that there is no tearing paper fiber or white powder at the bonding of the corrugated peak, it is false sticky, which will cause the compressive strength of the paper straw to be low, and affect the strength of the entire paper straw.
3, the printing design is unreasonable
If the printing pressure is too large, it is easy to crush the corrugated and reduce the corrugated height. Especially when printing at the line, in order to carry out forced and clear printing at the line part, the entire cardboard will be crushed, so that the compressive strength of the paper straw will be greatly reduced, so it is necessary to avoid printing again as much as possible.
