China's packaging industry started in the early 1980s. After more than a decade of development, a ready-to-use packaging industry system focusing on paper, plastics, glass, metal, decorative printing, and packaging machinery has formed.
In 1997, the total output value of the national packaging industry reached 154 billion yuan, an increase of more than 20 times from 7.2 billion yuan in 1980. In the 40 major industries of the national economy, the packaging industry has risen to 14th place. In 1997, China reached 15.54 million tons of packaging paper and paperboard, ranking first in the six major packaging industries. The United States is the worldâ€™s largest consumer of paper and paperboard. In 1995 alone, the paper and paperboard consumption amounted to US$45.5 billion, accounting for 44% of the total US packaging consumption that year.
With the improvement of peopleâ€™s living standards and environmental awareness, the use of carton and carton packaging has become more and more widespread. However, China's carton industry is still unable to meet the needs of modern product packaging. There is no uniform carton standard and no strict design method. The carton box structure parameters are designed based on empirical analogy, which not only affects the carton The design and manufacturing precision also affect the efficiency of the company and the effect of product packaging. Therefore, a reasonable classification of the carton not only provides a bridge between the design and manufacturing departments of the carton box and users, but also facilitates the realization of the computer-aided design and manufacturing process of the carton, and also facilitates the user's telephone call. Ordering, in order to shorten the design, production cycle, reduce the packaging into water, promote the upgrading of products, improve the market competitiveness of goods.
First, the classification of cartons
Cartons are generally made of cardboard by folding, affixing or other connection methods, and are mainly used for the sales packaging of products. The carton's classification group material uses characteristics, manufacturing methods, shapes, structural forms, and packaging objects.
1. According to the production method of the tray, there are manual trays and mechanism trays.
2. Divided by the shape of the paper grid, there are square, round, flat, polygonal, shaped paper.
3. According to the packaging object, there are food, medicine, cosmetics, daily necessities, stationery, instrumentation, chemical packaging cartons.
4. According to the material characteristics, there are flat paper boxes, full-bonded cardboard boxes, fine corrugated cardboard boxes, and composite material boxes.
1 dry board cartons: used for sales packaging, such as white lunch boxes, yellow paper lunch boxes, cardboard boxes.
2 full-bonded paper lunch box: both for transport packaging, but also for sales and packaging, especially small and heavy commodity packaging.
3 small corrugated cardboard boxes: such as flat sticky corrugated cardboard boxes, ordinary corrugated boxes.
4 composite cardboard box: mainly made of thin cardboard and paper, cloth silk, aluminum foil, glass paper, used for juice, milk and other liquid packaging.
5. According to the thickness of the cardboard, there are thin, thick paper lunch boxes.
1 thin paper lunch box: such as white cardboard box, cardboard lunch box, tea cardboard box;
2 thick cardboard box: such as box paper lunch box, yellow paper lunch box, corrugated cardboard box.
6. According to the structure of the carton and the sealing form, there are fold-out carton, rocker-type carton, droop cover type carton, drawer type carton, foldable carton and gland-type carton.
7. According to the form of loan, there are two kinds of folding cartons and fixed cartons.
1 Folding cartons are tough, thin cardboard boxes that are printed, die cut, and indented. Its biggest feature is the storage and delivery of folded box pieces, which greatly saves storage space and shipping costs; it is suitable for automatic packaging, and can be used in automatic packaging machines to complete the process of hammering, forming, filling, sealing and other processes; easy to sell and The display is suitable for various printing methods and is conducive to the promotion and promotion of goods. It is easy to process and has a low cost. It is easier to process the cardboard into various shapes required by processing such as row knife, die cutting, folding, and bonding. The carton and its processing cost are much cheaper than metal, glass and plastic; it can play a role in fixing goods and protecting goods. Use aseptic sealing method or frozen fresh-keeping packaging can make the food not corroded and not deteriorated.
2 Fixed cartons are also called hard paper lunch boxes, thick paper lunch boxes or paste paste boxes. Consisting of a box body and a box cover, the box is made using a flat nail or a paste, but it cannot be folded. Most of them are supplied in the form of finished products, which greatly wastes storage and transportation space, increases shipping costs, and most of the processes use manual operations, resulting in high costs and low production efficiency. However, it has higher strength, stiffness and a nice appearance compared with folding cartons.
