Development History of Corrugated Boxes in China (I)

Normal > As the demand for corrugated paper box market continues to increase, China's corrugated paper box production equipment has been further developed, and higher requirements have been put forward for corrugated paper box production paper to meet the needs of various aspects of carton production. Therefore, the production of corrugated paper cartons and indeed with the continuous improvement of production equipment, improve and enhance the environment, transport and the development of the paper industry, paper carton production from the previous poor, low-intensity, high weight (high basis) to High-strength, low-weight ( low-quantitative ) direction of development to meet the large market wells in the field of domestic and foreign merchandise circulation with the international market, this is the inevitable result of corrugated box production and development in China. According to the author 's review of the development of corrugated boxes for more than 30 years, the production of corrugated box can basically be divided into three stages of development. It can clearly be seen that as the size of corrugated box production paper continues to expand and the production of cartons With the continuous improvement of the development and quality of paper, the production of corrugated boxes has also developed rapidly.

Normal >     China has not yet established its own packaging industry system. At the same time, other supporting industries surrounding the packaging industry are still lagging behind. Therefore, it is difficult to develop the packaging industry. At the time, corrugated box production equipment manufacturing and production of special corrugated paperboard production paper was essentially blank. The majority of carton manufacturers are small-scale workshops, and their factories are poorly equipped. Production equipment is extremely old and outdated. Corrugated box production mainly uses stand-alone production. Due to prolonged use, production equipment and lack of maintenance, rust stains, and some even still using very backward equipment in the 1930s, the production is simple, thanks to heavy manual workers, production-intensive, low quality of personnel, production The use of artificial monolithic laminar-type backward production methods, that is, completely relying on manual operation, the paperboard paperboard, corrugated paper and paperboard of the reel can be cut with a paper cutter according to the required length, and a few companies use the flanging machine. Longitudinal flanging is cut, and the flanks are cut horizontally and placed on the side. After a single machine is applied to the corrugated paper, it is placed on top of a piece of paper, and then the top paper is re-applied. The corrugated cardboard is thus made. Then, the above-mentioned stacking board is continuously stacked, and the corrugated board is pressed tightly by its own gravity to facilitate the sticking of the surface paper, the corrugated paper, and the inner paper. Because it is impossible to control the humidity of the water, the prepared cardboard is pulled to the open air in the open air. At that time, the company had not yet established the conditions for drying rooms. In the event of a rainy weather, they could only be placed in the workshop, making the already untidy workshop even more crowded. This method of natural drying by weather causes the carton production to be very passive. After the cardboard is made, it is then formed into a box, including manual separation, pressure lines, chamfering, and opening of the bad, and then using a very backward screen printing, fishing box. The production efficiency is very low, and the quality of corrugated boxes is not guaranteed at all. Corrugated cartons can only be used for low-level consumer goods packaging. At that time, China's papermaking raw materials were in short supply and strained. In particular, there was a shortage of wood resources for the production of wood pulp, which could not provide large amounts of wood pulp for the papermaking industry. Therefore, the raw materials for paperboard production are mainly grass pulp ( wheatgrass and rice straw pulp ) , waste pulp, and a small amount of waste hemp as a substitute for long-fiber raw materials. Domestically-used cartons are made of 420g /pu, 450g /cm or Higher grammage of linerboard, using cheaper 420g / nf yellow paper, 330g / nf teaboard paper or linerboard with 365g /pu, and corrugated paper with a high basis weight of 180g / rf . Corrugated paper for strength paper. There are also some cartons that are made from kraft linerboard with a few wood pulp noodles. In terms of corrugated boxes for export goods packaging, very few imported kraft linerboards with 360 g/pu and 337 g/ if and domestically produced 420 g/ If and 365 were used.
