Development History of Corrugated Boxes in China (Part 2)

The third phase:

From the mid-late 1980s to the beginning of this century

This is a period of rapid development in corrugated box production. With the abundance of commodities, the demand for corrugated paperboard packaging has increased sharply in both domestic and international markets. Cartons manufacturing companies have been continuously built and expanded throughout the country. The original corrugated box manufacturers have also expanded their production facilities in order to expand corrugated box production capacity. With technological innovation, new corrugated board production lines and post-carton production equipment have been newly added, and the entire corrugated paper box industry has gradually changed from a single-sided machine to a fully automatic and large-scale historic transformation. At the same time, it also raises higher requirements for the production of corrugated paperboards to meet the needs of large-scale, automated and high-efficiency production. The corrugated paperboard production paper sources are diversified.

Due to the construction and production of some paper-making companies' products and corrugated box production paper production enterprises, there are many items of paperboard production paper, and various grades and weights of linerboard and corrugated paper are continuously put on the market. The use of corrugated boxes for production of paper is no longer limited to fixed-point companies, but is fully liberalized according to the market. Carton manufacturers have increased their choice of cardboard. However, in the selection of corrugated paperboard production paper, there is still a contradiction between the use of high grammage and low grammage. Since the foreign trade and commodity inspection authorities still have strict regulations and requirements for the export of corrugated paperboard and production paper, such as Exports of double corrugated paperboard production paper should generally use imported 337g/If, 360g/nt and 180g sight, 160g/n4 niu card and high-strength corrugated base paper materials, domestic materials basically do not agree to replace. However, with the development of papermaking industry in China, some paper-making enterprises have actively developed the production of corrugated paperboard for export, such as Hangzhou Huafeng Paper Mill, which produces 360g of corrugated boxes for export goods and high-end packaging. Kraft liner board, cardboard surface with natural leather pulp noodle, clean and smooth paper, printing performance, high physical strength, the main technical indicators exceed the Japanese JIS industry standards; indicators, and won the national silver medal. The successful trial production of homemade corrugated box production paper undoubtedly opens up broad prospects for the localization of corrugated box production paper. Afterwards, many papermaking enterprises and Chinese-foreign joint venture papermaking enterprises gradually developed a low-quantity direction of 300g/if based on the situation of corrugated paperboard production in China, and at the same time gradually reduced the quantitative production of corrugated paperboard for export goods. For example, the imported 337g nf used in the past was changed to 320g/Nickel card, and the domestic bull card 360g/nf was changed to 320g/nf, etc., and the approval and support from foreign trade and commodity inspection authorities were obtained. At the same time, trial production of 200 g/m9 kraft paperboard changed the condition of a single variety of kraft linerboard in China, which is basically only 360 g/if.

High-strength corrugated base paper, which is another main raw material for corrugated box production, also made progress at the earlier time with main specifications of 200 g/If, 180 g/Id, and 160 g/m. However, due to the rapid development of corrugated cartons production, and the use of corrugated paperboard to further align with international standards, the high-strength corrugated base papers that are more suitable for carton production are gradually promoted and developed, such as 180g/nf, 150g/feed, and 125g/If. Due to the appearance of the new type of corrugated type, the high-strength, low-weight base papers of 127 g/If and 115 g/nf were also present, and the variety of corrugated cartons was diversified. In the early 90s of last century, in the corrugated paperboard production paper, due to the corrugated paperboard national standard and the corrugated paperboard standard for export products, the technical requirements for corrugated paperboards are compressive strength, burst strength, side pressure strength, punching degree, and water content. Rates and other items are directly related to the production of paper, the level of paper quantification also affect the above test results. Therefore, most manufacturers of corrugated cartons are faced with low-weight (low-quantity) cardboard and corrugated base papers in the market, but they still use corrugated cardboard with high basis weight to ensure the quality of the cartons when producing single- and double-corrugated cartons. . In front of the user to high quality cardboard quality, improve its corporate reputation and visibility. Another reason for setting cardboard sizing is because of the various items that are directly related to the carton inspections sent. Corrugated paperboard national standards (GB-6544-86) must comply with regulations for the production of corrugated box production paper materials, with cardboard paper rations were 250 g/nf, 280 g/If, 300 g If, 320 g/If, 360 Gram/If, corrugated paper is 125 g/lf, 150 g nf, 180 g/If, and the corrugated paperboard for packaging of export products is also clearly stipulated and must meet the requirements of the standard. In this way, the normal single and double corrugated board will have a high weight of about 1000-1100 g/1f, which will ensure the quality of the carton on the basis of quantitative assurance. If it is lower than the above quantification, several physical indicators in the standard may not be met in the test. Due to the general attention of participating companies, the production of corrugated paperboard for the delivery of samples is relatively good, and the failure to meet the requirements rarely occurs. Zhejiang Province has also listed corrugated box products as one of the best products in the province. As a packaging product for the first time, it is also a major event in the carton industry.

After more than 20 years of hard work, corrugated cartons manufacturing enterprises across the country have produced corrugated cartons with a considerable scale and become the pillar products of the packaging industry. According to statistics, in 1998, there were 1,056 corrugated board production lines in the country, reaching 3,000 in 2003. Corrugated board production lines in some coastal provinces and cities have developed even more rapidly. In addition to domestic production of corrugated board, but also from abroad to introduce various models, specifications, brands of large corrugated board production line. In 1997, 84 automatic corrugated cardboard production lines in Zhejiang Province exceeded 200 in 2002. The quality of corrugated paper in the provinces and cities, even in the mountainous areas and small towns, is very important to meet social needs. As the production of corrugated cartons soared, the demand for paper also rose rapidly. With a full corrugated board production line with annual board production capacity of 1500-2000 million square meters, only the automatic production line in Zhejiang Province can produce 3.5 billion to 40 billion square meters of paperboard annually, and then produce thousands of corrugated cartons in the province. The annual production capacity of single-sided paperboards still used by enterprises is calculated on the basis of one single-faced machine ranging from 800 to 10 million square meters, with a total of 8 to 100 million square meters. Its corrugated box production capacity is evident. Of course, there is still a big gap between actual production and actual output. In 1996, Zhejiang exported only about 500 million square meters of packaging cartons. In 1992, it was about 800 million square meters, excluding corrugated cartons sold domestically. According to relevant data, the output of corrugated cartons in China reached 15.8 billion square meters in 2003. This shows that the rapid development of corrugated box production has greatly promoted the development and development of corrugated box production paper in the paper industry. Corrugated cartons for corrugated box production With the development of carton production, based on the traditional A, B, C, and D popular models, ultra-thin film C-type and F-type and K-type extra corrugated sheets have been developed for use in a larger range. The packaging of goods, so that the production of corrugated paper production has gradually undergone a fundamental change in order to adapt to the new commodity packaging market.

Domestic paper-making companies also spotted a vast market with great potential for corrugated paperboard production, and introduced advanced papermaking equipment one after another to upgrade the original equipment for technological transformation and to make papermaking technology develop faster. . At the same time, significant improvements have been made to the raw material structure of corrugated box production paper. The improvement of pulp quality depends on scientific formulas and advanced technologies. On the other hand, the establishment and construction of fast-growing forest bases for papermaking in China have greatly increased the output of domestic pulp. At the same time, wood pulp and waste paper purchased from abroad are also an important factor in rapidly improving the quality of domestically produced corrugated box production paper, thereby enabling the production of corrugated box production paper (including export merchandise corrugated boxes and domestically sold merchandise corrugated boxes) not only in quantity but also in quantity. Aspects and qualitative changes have taken place. In particular, the high-strength and low-weight corrugated base paper, which has long depended on the import of important raw materials for corrugated cartons, has also been successfully developed. It has changed the long-term dependence on the main raw materials of kraft linerboard and high-strength corrugated base paper for export goods from the United States, Japan and Finland. History of imports from countries such as Indonesia. Replacing imports with high-quality domestically-made kraft linerboards and high-strength corrugated papers, and gradually realizing the localization of corrugated paper bags for export goods, this is a very important reform in the carton industry. On the other hand, it has changed the situation of the use of high-heavy, low-strength cardboard and corrugated paper in corrugated paperboard production in the past, and has developed toward high strength and low weight. Facts have proved that the quality of carton has generally improved through the inspection of corrugated boxes and the inspection of exported goods in recent years. Ten years ago, the author, as the head of the Provincial Paper Association's paper committee, had communicated with his Japanese counterpart about corrugated paper box technology. Japanese friends had talked about the prevalence of quantitative overweight of carton board in China's export goods. The use of paper is unreasonable and should be gradually reduced. Not only can valuable raw materials be saved, but also transportation costs can be reduced, but the premise is to improve the production of corrugated boxes. Paper quality, reduced grammage, increased strength, and better physical properties, improved transport conditions and environment. In recent years, great achievements have been made in this area. Another important reason for the reduction in quantification is that the current transport environment has also been greatly improved. Export goods are generally shipped in containers through corrugated boxes, which greatly reduces the rate of carton breakage and effectively protects the contents. The domestic sales of corrugated cartons are also due to the improvement of quality, so that the goods are better protected. These provide a broad space for the low-weight and high-strength development of corrugated cartons, and are also the direction for the development of corrugated cartons in the future.
