The selection of the material and thickness of the paper box is one of the key factors determining the quality of the paper box. The appropriate material and thickness can improve the stability and load-bearing capacity of the carton, and protect the packaged goods from damage. The main materials of the paper box include corrugated cardboard, grey cardboard, matte cardboard, linen cardboard, white cardboard and so on. Corrugated cardboard is the main material of the paper box, which is composed of paper core and face paper. The paper core is formed by the cross of vertical and transverse textures, which can provide the strength and rigidity of the cardboard. Face paper is paper covered on both sides of the paper core to protect the core from damage. Kraft paper board is a hard cardboard that has a strong load-bearing capacity after drying. According to the specific needs, you can choose the appropriate paper box material.

In the color box printing, many aspects of the conditions will affect the quality of printing, the need to maintain a pass rate of more than 99% is not easy. For the influencing factors are also more, such as: printing equipment, paper material, the use of environmentally friendly ink, printing temperature, the technical ability of the operating captain, etc., good reputation is created step by step. We use FSC paper source, the use of Germany, Switzerland, the United States, Japan, France and other places to import more than 100 advanced printing equipment, the current printing workshop operation is mainly responsible for the average length of 20 years of captain nearly half, rich technology and experience. International G7 color management, 24 hours operation, to ensure our quality and delivery standards. How to achieve quality standards? First of all, we need to change the quantity control, such as the following 9 quality control points.

​Honeycomb paper is made of honeycomb paper through a special punching device and mold punching, which can replace foam as a buffer for the lining. It is a revolutionary new environmental protection product in the packaging industry. Honeycomb paper packaging has a wide range of applications in the fields of electronics, household appliances, equipment and glass ceramics. It is construction, aluminum, steel, other metals, in addition to brick, candy, frozen foods, daily necessities, home appliances, chemicals, medicine, computers, other high-tech products, and so on. This is because they all have a lot of surfaces and corners that need to be protected. In addition, the paper corner guard can also be used for the transport of fruit, both to provide protection, and to allow the cargo to maintain air circulation during transport.

Honeycomb paper is made according to the principle of honeycomb structure in nature. It is a new type of environmental protection and energy saving material that connects corrugated base paper into numerous hollow three-dimensional hexagons by gluing method, forming a whole stressed part - paper core, and gluing face paper on both sides.

Factors affecting the compressive strength of cartons 1. The carton is composed of various layers of paper, and the reasonable collocation of paper is the basic condition to ensure the compressive strength of the carton. Through the physical properties of each layer of paper testing, we can initially calculate the compressive strength of the carton, and then through the calculated compressive strength, the various processes in the production process of carton compressive strength control.
