In recent years, in order to meet the requirements of packaging industry reduction and environmental protection, the trend of micro-corrugated cardboard has risen. For example, the United States, Sweden, Germany, Spain and other countries have begun to expand the scale of production of F flute and C flute, and began to more subtle Direction exploration. Some countries have begun to use N flute (flute 0.46mm) and O flute (flute 0.30mm). In the field of traditional fiber carton applications (such as alcohol, footwear, small appliances, hardware tools, microelectronics, computer software, etc.), micro-corrugated cardboard boxes have begun to compete with the traditional thick corrugated cardboard market. According to market analysts, 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 board will reach 7 billion square meters.
As a traditional packaging material, corrugated paper has been widely used in many fields such as industrial products and various kinds of civilian goods. Moreover, with the restrictions imposed by the international market on the quarantine of wood packaging for goods, wooden boxes and metal boxes have been replaced in some cases. The industry believes that in the face of the rapid development of foreign micro-corrugated cardboard and the demand of China's packaging market, China's corrugated paperboard industry should change the relative backwardness of current technology, equipment and management as soon as possible, and increase the development of micro-corrugated paper market. Manufacturers should step up the development of fine tile lines, improve box making machinery, and actively promote the development of micro-corrugated cardboard and its packaging products. The reason why micro-corrugated cardboard can be rapidly developed in the packaging industry is that, as analyzed in this paper, it has four major advantages that it has adapted to the needs of the market.
1. High compressive strength - more reliable protection products
In terms of the characteristics of the corrugated paper itself, the micro-corrugated board has a higher compressive strength than a normal solid paper box at the same grammage. Due to the ratio, according to their characteristics, people can combine different types of enamels according to different purposes, and process and manufacture different packaging products to package products of different weights, types, and grades. For users who have higher requirements on the compressive strength of packaging, using microwatt packaging is an ideal choice.
For example, ice cream is a food that needs to be frozen, and it is easily affected by the external environment during transportation, resulting in deformation of the shape. Due to the small size of the fine corrugated packaging and the large number of corrugated strips per unit area, the pressure resistance of the packaging is improved, and the product has better protection function and is very suitable for ice cream product packaging. Moreover, it has the advantages of low temperature resistance, moisture resistance, and the like while improving compressive strength and cushioning performance.
2. Good cushioning performance - replace traditional lining for environmental protection
The use of micro-corrugated cardboard as the inner lining to replace the traditional buffer material, it is not only environmental protection but also can increase the compressive strength, it is an ideal buffer material. Now, many perfumes, cosmetics and other products are lined with fine corrugated cardboard, which not only improves the compressive strength of the package, but also improves the grade of the package. Many digital and small home appliances are lined with micro-corrugated cardboard to replace traditional EPE, EPS and other buffer materials. Because of the small size of the emblem, together with the selection of high-strength corrugated base paper, the cost is lower and more environmentally friendly. In a sense, corrugated paper products are easily recycled and recycled and are an ideal "green packaging" material.
3. The printing effect is good - advertising the exquisite pattern text
In the past, traditional corrugated corrugated cardboard could only be printed on gravure, and it was not possible to directly print out high-definition images such as photos. The deformation of the paperboard would destroy the strength of the cardboard, greatly affecting the accuracy and stability of the printing, and it was extremely easy. Cardboard runaway, uneven thickness, affect the synchronization of printing speed, resulting in blurred patterns, causing great unnecessary waste. The micro-corrugated cardboard can be directly printed on the offset printing, which can not only obtain beautiful patterns, but also can not cause the corrugated paper to deform, reduce or destroy the strength of the cardboard due to printing. Offset direct printing makes the fine corrugated packaging printing more exquisite, highly displayable and advertising, and greatly improves the packaging quality. Therefore, more and more industries have begun to use fine corrugated packaging as sales packaging. In addition to the traditional food, toys, and home appliances industries, industries such as handicrafts, medicines and health products that require external packaging and gifts have also begun to use micro-tiles. package.
The exquisite printing effect is an important reason why many cold drink companies insist on using miniature corrugated packaging. Products such as Nestle's Moonlight Box and Lu Xue's Melaleuca Snow Ice Cream are all using tiny corrugated packaging. On the one hand, it is used as an outer package, which requires beautiful and beautiful printing; on the other hand, it is an inner package that requires low temperature resistance. Most of these product's fine corrugated packaging are printed directly by offset printing. The printing effect is good, the color is gorgeous, and it has strong color performance. When coated with UV varnish, not only does it have a waterproof effect, but it also increases the compressive strength of the package. At the same time, because micro-corrugated cardboard has excellent physical properties and better printing adaptability, it shows a strong realistic visual effect, giving a beautiful enjoyment, thereby stimulating consumers' desire to purchase, to achieve the purpose of promoting product sales.
4. High quality and light weight - cost effective
High quality, light weight and cost savings are another big advantage of miniature corrugated packaging. It is understood that some manufacturing companies have replaced E-paper micro corrugated paperboard in place of B flute, G flute and other single corrugated paperboards used in the past. Their packaging not only meets the requirements for safe transportation of the original product, but also can reasonably reduce packaging materials and transportation costs each year. . The exquisite printing effect of mini-corrugated cardboard makes it a better choice for making display-type corrugated cardboard display racks and other display packaging. In foreign countries, due to the high precision of die-cutting of the mechanical equipment itself, in the production of poster-type corrugated cardboard display racks, a large number of fine paperboards such as C flute, N flute, and F flute have been used in place of traditional PVC sheets to make the entire poster-type corrugated cardboard display stand. Lighter weight, lower cost, not only easy to transport, but also easy to recycle.
