Among the four major packaging materials: paper, plastic, metal, and glass, paper packaging materials are the cheapest and can be recycled and reused, which is good for environmental protection and therefore has the fastest development. Common paper products are: food cartons, napkin cartons, cardboard boxes, corrugated boxes, food paper bags, packaging paper barrels, handmade paper art, and various gift packaging paper products and gift boxes.

Because special paper is different from ordinary paper in terms of material, structure and performance, there are also differences in printing process. Need to pay attention to two aspects.

Offset printing is mainly used for printing of paper-based materials. Sheetfed offset presses can be printed in different formats and are more flexible. At present, the printing format of most web offset presses is fixed. Its applications are limited. With the development of technology, the web offset printing press is also continuously improved. Web offset presses that can change the printing format have now been developed. At the same time, we developed a web offset press for seamless cylinders. The printing cylinder of this web offset printing machine is seamless, and in this respect is already the same as the web gravure printing machine. Offset presses are also constantly improving in printing functions. Corrugated cardboard can be printed by improving and adding some parts. By improving and adding a UV drying device, UV prints can be printed. The above improvements continuously expand the use of offset printing machines in the field of packaging printing. Water-based inks for offset printing will soon enter practical applications.

The creative packaging box should clearly convey the information, the quality of the performance, the unique and outstanding performance of the market positioning and stimulation of the senses, and contain a rich design culture.​
