With the rapid development of the carton industry, carton machinery companies have also risen accordingly. Before the 1970s, carton production equipment was operated manually with low production efficiency. In the 1980s, some carton companies began to introduce Japanese equipment, corrugated cardboard production lines, water-based printing slotting machines, round pressure round die-cutting machines, etc. Domestic carton machinery companies started to imitate the introduced equipment. Due to the high prices of imported equipment, most domestic carton companies could not afford them, which opened up sales opportunities for domestic machinery companies. However, the trend of high-speed and high-tech development of carton machinery equipment is already clear.

The corrugated cardboard production lines introduced by carton companies in the early 1980s have been in use for over 20 years and are now being phased out in favor of newer production lines. Some large and medium-sized domestic carton companies have the economic and market competitiveness; they need high-quality, high-speed, and wide corrugated cardboard production lines. If domestic machinery companies can produce "four highs and one width," they will definitely be accepted by carton companies. The price difference between domestic lines and imported lines is significant, and without strong economic backing, the imported lines are unaffordable, while domestic lines are more easily accepted by carton companies due to their lower prices. Of course, there are still gaps between domestic production lines and products, mainly in terms of structure, speed, material, and processing precision. However, with strengthened research and continuous improvement, it is possible to catch up within 8 to 10 years.

The future direction of the carton machinery manufacturing industry is to reduce ordinary corrugated lines and develop medium corrugated lines. Three-layer and five-layer ordinary corrugated lines are considered low-end products. Due to their slow speed, poor quality, and low grade, they cannot meet market demand and limit the development of carton companies. Some companies have used ordinary corrugated lines for too long, leading to equipment aging, while some small and medium-sized enterprises, due to economic conditions and sales limitations, can only temporarily purchase ordinary corrugated lines for production development. Additionally, different regions should be treated differently.

Single-sided corrugating machine groups emerged in the late 1980s to early 1990s, replacing manual operation and meeting the needs of small and medium-sized carton companies. However, compared to corrugated cardboard lines, the cardboard produced by single-sided corrugating machine groups is soft, of poor quality, and has significant waste of raw paper. Currently, a production pattern of "centralized board making and decentralized box making" has formed within the industry, and single-sided corrugating machine groups will inevitably be eliminated.

The corrugated cardboard production line will be equipped with DE single-sided machines and longitudinal cutting computer thin blade splitting machines. The downstream equipment will include high-speed, multifunctional, multi-color printing slotting machines, flat pressure flat high-speed die-cutting machines or creasing machines, thin blade splitting creasing machines, printing surface laminating machines, automatic or semi-automatic gluing machines, as well as laser computer engraving machines and flexible plate processing equipment.

The development of downstream processing equipment for cartons is the future direction for carton machinery companies. The production structure of cartons is being adjusted, entering a new pattern of collaborative production. Newly established carton companies in Shanghai generally adopt a model of purchasing cardboard and processing it in downstream operations to produce cartons. This model requires less investment, yields quick output, has low costs, and good benefits. The downstream processes of corrugated cartons are an important part of carton production. After addressing cardboard quality, the processes include printing, splitting, gluing, and die-cutting.

From the development trend of the carton machinery industry in the new century, the first is to accelerate the development of medium cartons, focusing on low weight, high strength, and lightweight medium to high cartons; the second is to develop flexible plates for multi-color surface printing and die-cutting of cartons; the third is that kraft paper box board for transportation packaging is gradually being replaced by white board kraft paper with color surface printing for commodity packaging, achieving commercialization and serialization of internal and external packaging; the fourth is to develop irregular carton boxes and fine corrugated (DE) carton boxes, achieving aesthetic, generous, and lightweight designs through die-cutting to provide convenience for consumers.
