Analysis of the Application of Miniature Corrugated Boards

Miniature corrugated cardboard usually refers to corrugated cardboard with a height above E楞 and below (ie, up to a height of <1.1mm), including F楞, G楞, N楞, and O楞. Due to its thinner thickness, compared to cardboard and general Corrugated cardboard is lighter in weight and more dense, making it ideal for use as a packaging insert. In recent years, with the development of micro-corrugated board manufacturing, the application of micro-corrugated board has gradually expanded. For example, our company uses F-type corrugated board as the inner support for social packaging, instead of solid paperboard, F-type corrugated paper with its inherent high Intensity gives the product better protection in the same quantity.

At the same time, with the continuous enhancement of greenization, environmental protection, and reduced packaging requirements, the use of miniature corrugated cardboard as a product packaging will also become a development trend. Comparison of performance compared to cardboard

According to tests, the F-type corrugated cardboard with a basis weight of 100 g/m2 is basically the same as the cardboard with a basis weight of 350 g/m2, but the sliding friction coefficient is 30% to 40% larger than the paper jam, and the thickness is even higher. Compared with the compact structure of cardboard, the corrugated hollow structure can play a better role in buffering and absorbing sound absorption.

From the perspective of the structure of social packaging, the display requirements for the box type are getting higher and higher. Generally, it is necessary to open the skylight on the surface of the carton or perform hollow die cutting so that consumers can see the contents of the package. Due to the characteristics of micro-corrugated cardboard, the superiority of its application is even more pronounced for cartons that require better display. Ordinary cardboard If you open the skylight, the compressive strength of the carton will be significantly reduced, while the micro-corrugated paperboard because of its inner core layer is a U-shaped or UV-type groove structure, its stiffness and compressive strength after open sky treatment All will be significantly better than ordinary paper jams, and both display effect and transportation effect have great advantages.

Compared with ordinary corrugated board, the color of micro corrugated board is mostly based on the original paper, there are also some white, black and color, while the ordinary corrugated board is mainly the original paper color.

Compared with ordinary corrugated board, the micro corrugated board is significantly lighter, more convenient to form, more delicate surface structure, and can be directly printed, without the need for a layer of printing surface paper as ordinary corrugated board, reducing the number of operating procedures. It helps with quality control. The strength of ordinary corrugated board is damaged after being deformed by pressure, which affects the printing accuracy. After the improved coating of micro-corrugated cardboard, the surface smoothness is very good, the ink adhesion is also improved, and can be directly printed on the offset printing machine. More capable of hot stamping, indentation and other post-press processing.

Price comparison In terms of price, although micro-corrugated cardboard prices are higher than ordinary corrugated cardboard, but the balance of labor costs and processing costs, it should be said that there is no significant difference. However, compared with the carton made of ordinary corrugated cardboard, the carton edge of the carton made of micro-corrugated cardboard is slightly inferior, that is, the protection is not enough, and it can not meet the market demand for packaging of sharp objects.

Compared with cardboard, the price of micro-corrugated cardboard with the same area is 2-3 times higher than the price of cardboard, but the strength of the carton made from micro-corrugated cardboard can meet the strength of the B-type and C-type corrugated cardboard boxes. Needed, therefore, the outermost corrugated cartons or courier packaging can be directly cancelled during the transportation process, which not only meets the requirements for safe transportation of the original products, but also can reasonably reduce the amount of packaging materials and reduce the transportation cost each year.

For the corrugated boxes currently used by our company, the cost of a corrugated box with a volume of 0.3m3 is about RMB 5/piece, the original white card is calculated at RMB 1.8/m2, the F-type corrugated paper is calculated at RMB 4.8/m2, and the F-type corrugated box Cardboard is about 2.7 times more expensive than white cardboard. Suppose a corrugated box is loaded with 100 cartons, a large cardboard box can be used to make 10 cartons, 10 large cardboard boxes are needed, and cartons made from white cardboard need to be repackaged in corrugated cartons. The cost of adding corrugated cartons is calculated. Corrugated cardboard is only about 2 times more expensive than white cardboard. Moreover, the labor cost and time cost of packing are not considered in this process.

In this way, micro-corrugated cardboard can not only save storage and logistics costs, but also improve overall production efficiency. Moreover, the weight of the micro-corrugated board is significantly lighter than the corrugated box plus the weight of the white card, and the transportation costs are also reduced. However, compared with miniature corrugated paper, white card printing is easier, printing color is more vivid, and post-press processing such as hot stamping, embossing and embossing is also more mature and has better results. However, it is believed that with the development of micro-fabricated corrugated paperboard technology and the matting technology of paperboard and paperboard, the fineness of micro-fabricated corrugated cardboard will be higher and the adaptability of the embossing cylinder will be better. , printing and post-press processing will not become its application bottleneck.

At present, our company's products are mainly cardboard, and corrugated cartons as external packaging are made by specialized corrugated paper cartons, often involving some issues of warehousing, supply, and outside quality control. If the application of miniature corrugated cardboard as an outer carton is realized, the uncontrollable factors in these links can be completely avoided and the whole production process will be more efficient.

At present, micro-corrugated cardboard has gradually been applied in small appliances, microelectronics, hardware, express packaging and other fields. It is believed that with the improvement of its printing and post-printing processing adaptability, it will help our company's social packaging business (cosmetics, high-grade Marketization of daily chemical products).
