In recent years, in order to meet the requirements of reduction and environmental protection in the packaging industry, the trend of micro corrugated board has risen, such as the United States, Sweden, Germany, Spain and other countries have begun to expand the production scale of F-shaped and C-shaped corrugated board. This design strategy is conducive to maintaining the balance between cost and performance, and began to explore in a more subtle direction. Some countries have begun to use n-shaped bar (bar height 0.46mm) and O-shaped bar (bar height 0.30mm). In the application fields of traditional fiber cartons (such as alcohol, shoes, small appliances, hardware tools, microelectronic products, computer software, etc.), micro corrugated cartons have begun to compete with the traditional thick corrugated cardboard for the market. Market analysts predict that in the next five years, the demand for micro corrugated paper in Europe will increase by an average of 5.6% annually, and the total growth of micro corrugated paper will reach 7billion square meters

As a traditional packaging material, corrugated paper has been widely used in many fields, such as industrial products and various civil commodities. Moreover, with the restrictions of the international market on the quarantine of wooden packaging of goods, wooden boxes and metal boxes have been replaced in some cases. Industry insiders believe that in the face of the rapid development of foreign micro corrugated board and the demand of China's packaging market, China's corrugated board industry should change the current relatively backward technology, equipment and management as soon as possible. Local chitosan is a cationic polymer surface, increase the development of the micro corrugated paper market, and equipment manufacturers should step up the development of fine corrugated board lines and improve the box making machinery, Actively promote the development of micro corrugated board and its packaging products. The reason why micro corrugated board can develop rapidly in the packaging industry is that it has four advantages, which meet the needs of the market, as analyzed in this paper

1. High compressive strength, more reliable protection products

in terms of the characteristics of corrugated paper itself, under the same gram weight, the compressive performance of micro corrugated paper board is better than that of general solid paper boxes. Because of its characteristics, people can combine different ridge types according to different uses to manufacture different packaging products for packaging products of different weights, types and grades. For users who have high requirements on the compressive strength of packaging, micro tile packaging is an ideal choice

for example, ice cream is a food that needs to be frozen, and it is easy to be affected by the external environment during transportation, resulting in shape deformation. Due to the small corrugated type and the large number of corrugated strips per unit area, the micro corrugated packaging improves the compression resistance of the packaging and has better protection function for the products, which is very suitable for the packaging of ice cream products. Moreover, while improving the compressive strength and cushioning performance, it also has the advantages of low temperature resistance and moisture resistance

2. Good cushioning performance. Replacing the traditional lining is beneficial to environmental protection.

using micro corrugated cardboard as the lining to replace the traditional cushioning material is not only environmentally friendly, but also can increase the compressive strength. It is a very ideal cushioning material. Now, many perfume, cosmetics and other products are lined with fine corrugated cardboard, which not only improves the compressive strength of packaging, but also improves the grade of packaging. Many digital and small household electrical appliances are lined with micro corrugated cardboard to replace traditional cushioning materials such as EPE and EPS. Due to the formation of one piece of fine corrugated and the selection of high-strength corrugated base paper, the cost is lower and more environmentally friendly. In a sense, with the support of national "863" and natural science foundation projects, corrugated paper products are easy to recycle and reuse, and are an ideal green packaging material

3. In the past, the traditional corrugated cardboard can only be printed on gravure, and can not directly print high-definition patterns like photos. Due to pressure deformation, the strength of the cardboard will be destroyed, greatly affecting the accuracy and stability of printing, which is very easy to cause deviation and uneven thickness of the cardboard, affecting the synchronization of printing speed, blurring the pattern, and causing great unnecessary waste. The micro corrugated board can be directly printed on offset printing, which can not only obtain beautiful patterns, but also will not deform the corrugated paper, reduce or destroy the strength of the board due to printing. The direct offset printing method makes the printing of micro corrugated packaging more exquisite, highly display and advertising, and greatly improves the grade of packaging. Therefore, more and more industries begin to use micro corrugated packaging as sales packaging. In addition to traditional food, toys, household appliances and other industries, many industries that need external packaging gifts, such as handicrafts, medical and health products, also begin to use micro corrugated packaging

the exquisite printing effect is an important reason why many cold drink enterprises insist on using micro corrugated packaging. Products such as Nestle's Moonlight box and heluxue's thousand layers of snow ice cream are all packed in micro corrugated packaging. On the one hand, as an outer package, it requires beautiful printing; On the other hand, as an inner package, it is required to be able to withstand low temperature. Most of the micro corrugated packages of these products are printed directly by offset printing, which has good printing effect, gorgeous colors and strong color expression ability. After applying UV varnish, it not only achieves the effect of waterproof, but also increases the compressive strength of the package. At the same time, because the micro corrugated board has excellent physical properties and better printing adaptability, it reflects a strong realistic visual effect and gives people a kind of beauty enjoyment, so as to stimulate consumers' desire to buy and achieve the purpose of promoting product sales

4. High quality, light weight, cost saving, high efficiency, sometimes problems will occur due to improper operation

high quality, light weight, cost saving, is another major advantage of micro corrugated paper packaging. It is understood that some production enterprises have adopted e-corrugated micro corrugated board to replace the single corrugated board such as b-corrugated board and g-corrugated board used in the past. Its packaging can not only meet the safety transportation requirements of the original products, but also reasonably reduce the packaging materials and transportation costs every year. The exquisite printing effect of micro corrugated board makes it a better choice for making poster corrugated board display shelves and other display packaging. In foreign countries, due to the high die-cutting accuracy of the mechanical equipment itself, when making poster corrugated board display frame, a large number of micro paperboards such as c-board, n-board and f-board have been used to replace the traditional PVC board, making the whole poster corrugated board display frame lighter in weight and lower in cost, which is not only convenient for transportation, but also easy to recycle
