[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer are less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the papers produced by different manufacturers are also different.
[0003] Some existing packaging cartons are foldable for easy product transportation. However, some existing foldable packaging cartons are formed into a diamond shape by squeezing the sides together for subsequent stacking.
