A durable waterproof carton

Abstract

The invention discloses a durable waterproof carton, and belongs to the field of cartons. The durable waterproof carton comprises a carton body, the six surfaces of the carton body are made of paper boards, each paper board comprises a bent paper board and two flat paper boards, the flat paper board and the bent paper board are mutually bonded and are distributed alternately, pre-buried water absorption rods can be filled between the flat paper board and the bent paper board, so that the interior of the corrugated board is subjected to waterproof treatment, and nano super-hydrophobic coatingsare arranged on the outer cross section of the flat paper board and the bent paper board, and the problem that external water or moisture enters the corrugated board through the gap at the cross section is completely eradicated to a great extent; compared with an existing paperboard, the carton made of the paper board is used for realizing waterproof treatment from inside to outside, meanwhile, due to the arrangement of the multi-layer waterproof barrier, the waterproof performance of the carton is effectively improved, due to the fact that the waterproofness is improved, the paperboard structure is not prone to being damaged by damp, and the durability of the carton is greatly improved.

Description

technical field [0001] The invention relates to the field of cartons, more specifically, to a durable waterproof carton. Background technique [0002] Corrugated cardboard is die-cut, creasing, nailed or glued to make corrugated boxes. Corrugated carton is the most widely used packaging product, and its consumption has always been the first among all kinds of packaging products. Including calcium plastic corrugated box. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers due to their superior performance and good processing performance, and have become the main force of transportation packaging. In addition to protecting the goods and facilitating storage and transportation, it also plays the role of beautifying and promoting the goods. Corrugated boxes are green and environmentally friendly products, which are conducive to environmental protection and are conducive to loading, unloading and tra...

AI Technical Summary

Problems solved by technology

[0003] Existing cartons are generally made of corrugated cardboard. The cardboard is generally an odd number of layers. It is usually formed by the distribution and bonding of plane cardboard and bent cardboard. Some cardboards usually have waterproof treatment on the outside, but basically no waterproof treatment on the inside of the cardboard. When the existing corrugated cardboard is made into a carton, the outward sections of the flat cardboard and the bent cardboard are generally directly exposed to the air. Due to the weather, rain or moisture will enter the inside of the cardboard through the exposed gaps, and get damp from the inside out, causing the carton structure to collapse easily and reduce the durability
