Under the category of national standard GB/T 4122, there are detailed standards and definitions of the latest packaging production process, including a total of 6 parts from 2008 to 2010.

Among them, the first part introduces the basic content of packaging; the second part introduces machinery; the third part introduces protection; the fourth part is materials and containers; the fifth part is inspection and testing; the sixth part introduces printing; the seventh part introduces packaging and surroundings.

In the first part, packaging terms are clearly defined as:
The general name of containers, materials and auxiliary materials used in accordance with certain technical methods to protect products during circulation, facilitate storage and transportation, and promote sales. It also refers to the operation activities of applying certain methods in the process of using containers, materials and auxiliary materials to achieve the above purposes. It can be seen that the design and production of packaging is the main content that runs through "packaging". It is complex and extensive, open and rigorous, and can be regarded as an applied technological discipline. To do a good job in packaging, it is necessary to have a considerable understanding of packaging software design, packaging materials, packaging machinery and equipment, and packaging, transportation and preservation. Only by having a comprehensive and comprehensive understanding of a technology can we grasp every aspect of it well. The same is true for the packaging process, let's take a look at it in detail.

Step 1: packaging design
This part is built on the basis of scientific software. The planner decides the product direction, and the designer leads the design content. Then, through graphic design software such as Adobe illustrate or Adobe Photoshop or Adobe Indesign and Corel CorelDraw, or three-dimensional design software such as Maxon Cinema 4D, Autodesk 3dsMax, Autodesk Maya, etc., operate and outline, draw and render the design composition diagram and effect diagram of the packaging box.

Step 2: material preparation
The preparation of packaging materials includes the preparation and procurement of basic packaging materials such as cardboard, glass, metal, and plastic, as well as auxiliary materials such as adhesives and cutting materials.

Step 3: packaging printing
This step is a key step for packaging to land. The design drawings given by the designer are printed in batches under the operation of the packaging machine. At present, there are mainly offset printing, flexo printing, gravure printing and other processes. Of course, rigorous packaging production must be tested before mass production. Some design effects or proofing effects are not satisfactory or substandard, and there is the possibility of repeated communication and repeated design revisions.

Step 4: packaging finishing
Packaging finishing is a packaging product upgrade operation to further improve the appearance of the packaging. Ordinary printing has been unable to meet the aesthetic level of contemporary people, so more and more packaging finishing, decoration, and finishing techniques have gradually matured. At present, the common packaging finishing processes are: glazing, hot stamping, embossing, compounding, laminating, etc. After these processes, the packaging will become more beautiful and colorful.

Step 5: die cutting
This step has reached the final stage of packaging molding. Through the processes of slotting, slitting, cross-cutting, compounding, and slitting on the printed packaging template, the packaging boxes, packaging bags, etc. are gradually formed. Some of the packaging boxes can be directly produced by printing and slotting machines, and the efficiency is objective, but special cases such as tray-type cartons, in addition to slotting, still need to be die-cutting like cartons. Of course, in the end, manual or mechanical folding is indispensable, and the folder gluer and adhesive are used for the finishing work such as gluing.
