There are many types of paper, such as lightweight paper, kraft paper, edging paper, dictionary paper, and synthetic paper for food packaging. Designers should be good at using various paper characteristics, not only calculate the size of printed products according to paper specifications, and not waste paper, but also recommend the use of some recycled and recycled environmentally friendly paper and processes as much as possible to enhance the corporate image and society of the brands they serve Public interest image.

Post-print processing of printed materials mainly refers to surface finishing, binding technology, and other processing methods to improve the pressure resistance, water resistance, and sealing or environmental protection performance of printed materials. The post-printing process in the industry refers to the surface decoration of printed matter as the main direction. Generally speaking, the post-printing process (hereinafter referred to as the printing process or process) mainly refers to a series of processing steps after the substrate is printed. It includes Die Cutting, embossing, embossing, creasing, bronzing, laminating, folding, punching, glazing, laminating, die cutting, binding, packaging, etc.

Hot stamping aluminum is also called "hot stamping", "hot stamping foil" or "hot stamping", etc. According to different printing materials, it can be divided into paper stamping, fabric stamping, leather stamping, and plastic stamping. According to different hot stamping templates and process technologies, there are hot stamping, cold stamping, single layer stamping, multiple stamping, and three-dimensional stamping.

Lamination, also known as "foil", "plastering" or "post-printing". That is, the plastic film coated with the adhesive and the paper-based printed matter are subjected to processes such as heating, pressing, and cooling. The surface of the printed matter is covered with a layer of transparent plastic film with a thickness of 0.012 to 0.020 mm (1.2 to 2 silk) to form a post-processing technology for paper-plastic printed products.

With the deepening of the concept of environmental protection and low carbon, health issues are becoming more and more important, and green color boxes have become a trend. Green color boxes and inks bear the brunt of it. Many people have therefore gradually paid attention to the toxic incidents of color box printing inks. In order to alleviate consumer concerns, color box printing is all about non-toxic and moving towards green printing. Take flexographic printing. Many companies have adopted water-based inks, which are basically non-toxic.

Let's take a deeper look at some of the reasons for choosing pit boxes for the production of outer packaging carton for many electronic products and data line cartons today.

From the point of view of the design of the high-quality Folding Carton, since the cardboard can not be folded and can not be folded easily, it is necessary to grasp a basic principle in order to design the high-quality cardboard carton into a folding box-like structure, that is, the part that needs to be turned back is realized by a slot similar to the skin shell. The structural design idea of the box-type of the fine folding packaging paper box is more from the book box in the fine paper box. The change of the box-type structure is mainly to make some changes in the closure mode of the leather shell and the leather shell, such as some leather shell by three cardboard, some leather shell by four cardboard, some leather shell by five cardboard.

Corrugated cardboard has two layers of corrugated cardboard, three layers of corrugated cardboard, five layers of corrugated cardboard, and even seven layers of corrugated cardboard. Then, what kind of cardboard is usually used for fruit carton packaging, because double-layer corrugated cardboard is a liner, a layer of corrugated base paper is bonded at 20%, and the cost is low, and it is only used as a separator and liner in fruit packaging; Three-layer corrugated cardboard, generally used for inner packaging, also used for grid board or layering. Liner; double corrugated cardboard, that is, five-layer corrugated cardboard, usually used for export packaging due to its good compressive strength.

According to the tension principle in the corrugated board forming process, the moisture content of the base paper entering the single-sided machine during the corrugating forming process is preferably 9% to 12%. Higher values ​​do not work, lower values ​​will affect the quality of the cardboard, so how do we control the temperature? Here are the control methods for two situation.

The base paper used to make cartons mainly includes white cardboard, corrugated paper, tea board paper, ordinary box board and kraft box board paper, etc. The production processes and materials of these base papers are different, and the standards are also different. There are two types of coated white paperboard:
