Discussion on the factors affecting the strength of carton
If the use of carton strength can not meet the use of demand, it can not normal use, from the formulation to make, there are three factors will affect the strength of the carton. Here’s what we're going to learn:
1. Box Shape: in the case of manufacturing, some customers like to make a variety of strange shapes, with boxy appearance, the strength of this kind of box will be reduced, in general, the supporting strength of the box is also relatively large in the box four edges and adjacent edge of the side, here can bear a lot of external thrust. In addition, a layer, the longer the box diameter, height-to-width ratio, the lower the strength of the box.
2. Hole Size: In the case of printing, the carton will have to be in one side of the hole solution, in the case of printing, itself will reduce the strength of the carton, and the larger the size of the hole, the lower the strength. In the case of opening, as far as possible to avoid the bottom edge near the edge, if no special provisions, the size of the opening as low as possible to control the better.
3. Corrugated Wave: The use of corrugated material carton strength and corrugated around 2 top and its junction shape has a certain relationship, in which the u-shaped corrugated arc, good cushioning and ductility, that doesn’t break easily, and the V is a triangle, which is relatively low in strength.
4. Pulp Consistency: when cartons are manufactured, if the pulp consistency is low and too many wet additives are added, the overall strength of the cartons will decrease after the end of production, the consistency of the slurry should be strictly controlled, which is also a prerequisite for quality assurance.
