Cartons are widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. So, how to distinguish the paper processed by cartons? Next, I will introduce how to distinguish the paper processed by cartons.
1、 In terms of hardness and softness, kraft paper is rich, and its toughness, hardness and stiffness are all good. In fact, boxboard paper is kraft paper mixed with old materials, with less ingredients and average quality. The tea board paper is the paper in the middle of the corrugated box, which is very soft. The simple hardness identification method is to pinch the paper surface with your nails. The easier it is to pinch, the worse the paper is.
2、 From the perspective of color differentiation, the color of kraft paper is natural, the box board is yellow, and the tea board is white, and very rough.
3、 In terms of weight, kraft paper is much heavier than tea paper per square meter due to the sufficiency of materials. According to the comparison, for a carton of No. 12 Post specification, kraft paper is more than 45g, while tea paper is not more than 35g.
The above is the summary of Xiao Bian on how to distinguish the paper for carton processing, and I hope it will be helpful to everyone.
