High-strength corrugated carton

Technical Field

The invention relates to the technical field of packaging boxes, in particular to a high-strength corrugated carton.

Background

The paper box is a three-dimensional shape and is formed by a polyhedral shape formed by moving, stacking, folding and enclosing a plurality of formed surfaces. The surfaces in the three-dimensional structure play a role of dividing the space in the space, and the surfaces at different parts are cut, rotated and folded, so that the obtained surfaces have different emotion representations. The carton display surface is formed by paying attention to the connection relationship of the display surface, the side surface, the top and the bottom and the arrangement of the packaging information elements. The corrugated case is a kind of paper case, which is also called a corrugated paper case or a paper box, sometimes called a paper case for short, and is a case woven or pasted by corrugated paper, and is often used as a package for articles to be transported conveniently. Corrugated boxes are widely used, but nowadays, the strength of the corrugated boxes on the market is relatively low, and the service life is short. Corrugated paper is a widely used carton making material, and has the advantages of high structural strength and low cost. Corrugated board means that a middle layer extending in a wave shape is arranged between two outer covering surfaces, so that compared with common hard board, the corrugated board has better structural strength. Existing cartons include a carton body having at least four walls and a bottom, and a lid.
