1. Miniature corrugated cardboard market development

Corrugated type in order of size. Followed by D, A, C, B, E, F, G, N and so on. E, F, G, and N cardboard are often referred to as micro-corrugated cardboard. Because of the high compressive strength of micro-corrugated cardboard, the printing effect is as good as that of cardboard, and there is great room for market development. Since the mini-watts were introduced in 1990, market usage has continued to rise. According to statistics, the current output of micro-corrugated cardboard accounts for 8% of the total corrugated board production. In 2004, the output of micro-corrugated cardboard in the United States accounted for 12%, and it grew at a rate of 2% per year. It is expected to continue to grow in the next five years, with a growth rate of about 20% per year.

2. G. Corrugated cardboard has great potential for development

According to predictions. G. Corrugated board production will increase significantly. Cardboard will have a 0% market share in the next 5 years by G. Corrugated board. Many years ago. Germany, the United Kingdom, France and other countries have implemented laws concerning waste recycling. As the decree sets clear regulations for the recycling of cardboard, the lack of clear regulations for the recycling of micro-corrugated cardboard has led to a large increase in the demand for micro-corrugated products. In addition, G 楞 corrugated board can be directly offset and has the advantages of good printing effect, low printing plate cost, suitable for short version of live, saving production costs and so on. Because of its popularity with users, market share has grown rapidly.

Some companies in Europe and the United States have already manufactured G-type corrugated products to meet the needs of customers, and more companies hope to produce G-type corrugated products in the future. ] In 998 Europe installed 30 pairs of G corrugated rollers. The United States installed 25 pairs in 1999 and installed 50 pairs. We believe that cardboard paperboard containers will increasingly be replaced with micro-corrugated paperboard containers, especially those paperboard containers with a basis weight exceeding 400g/m2.

In Japan. The law on the recycling of waste (ie, the laws governing the collection and recycling of containers and packaging) entered into force in April 2000. This has also affected the demand of users for corrugated boxes, which has replaced the use of corrugated cardboard for cardboard. Speed ​​up. Because G-Corrugated cardboard can be offset directly and traditional E-Corrugated cardboard needs to be laminated, replacing E-Corrugated cardboard with G-Corrugated cardboard has also become a trend. Large manufacturers of paper containers, such as textiles, hygiene products, frozen foods, toys, etc., have focused on the use of G楞.

3. Comparison of the characteristics of G-Corrugated cardboard and cardboard (see Table 1)

For carton manufacturers. The following problems exist in the production of G-Corrugated cardboard: (1) Whether the accuracy of G-Corrugated cardboard printing is the same as that of cardboard. (2) Manufacturing cost of G楞 corrugated cardboard. (3) G paper suppliers of corrugated cardboard. What kind of base paper is suitable for the production of G楞 corrugated cardboard? How to solve these problems. Raising the efficiency of corrugated cardboard production lines has become a problem that cartons have to face.

4. The current situation of miniature corrugated packaging in China

China's mini-corrugated cardboard production started late. Currently limited to the production of E-type corrugated. There are few varieties in terms of board quality and grade. The low grade needs further development. Miniature corrugated cardboard has better printability and higher stacking strength than the same amount of cardboard. Shock absorption performance is stronger. The lower cost has become the preferred packaging material for more and more small household appliances, food, mobile phones, and electronic products.

According to expert predictions, the annual demand for the miniature corrugated packaging market is about 20 billion pieces. And the annual growth rate remained above 40%. According to this, the deadline is 201 0 years. Miniature corrugated packaging will reach 32 billion pieces. This shows that there is a large market space for domestic miniature corrugated packaging. With the increase in the user's demand for ever-increasing packaging quality and reducing packaging costs. More and more companies and products will use miniature corrugated packaging.

Miniature corrugated packaging features

International miniature corrugated packaging has been applied to various fields. In addition to the production of color printing boxes, it can also be used as a liner to replace traditional buffer materials, poster-type corrugated cardboard display racks and other products.

1. Offset direct printing makes micro-tiles

Packaging and printing more beautiful, more display in foreign countries. More and more industries have begun to use miniature corrugated packaging as sales packaging. Not only traditional industries such as food toys and household appliances are used in large quantities, but many industries requiring high-end packaging, such as crafts and gifts, have begun to use miniature corrugated packaging and direct offset printing using micro-laminates. Corrugated board improves the grade of the product.

2. Miniature corrugated cardboard replaces traditional cushioning materials as an inner lining, which is environmentally friendly and can increase compressive strength

Nowadays, many perfumes and cosmetics such as LANCOME CHANEL are lined with micro-corrugated cardboard, which not only improves the compressive strength of the packaging but also enhances the packaging grade. Many digital and small household appliances are lined with micro-corrugated cardboard to replace the traditional buffer material EPE EPS. Due to the compact molding of the micro-corrugated cardboard and the selection of high-strength corrugated base paper, it is more cost-effective and environmentally friendly.

3. Miniature corrugated cardboard is used to make corrugated cardboard display racks, saving transportation costs

Miniature corrugated type is more detailed, printability is better, and printing is more beautiful, making it a better choice for making display packaging. In foreign countries, due to the high precision die-cutting of the mechanical equipment itself, in the production of corrugated cardboard display stands, not only corrugated cardboard is used as a support but a large number of micro-corrugated cardboards such as F楞G楞N楞 are used in place of traditional PVC sheets. Makes the entire corrugated cardboard display stand lighter to transport and easier to recycle, at a lower cost.

In China, the industries that use micro-tile corrugated packaging in addition to mobile phones and digital products (including digital cameras, MP3 CD digital voice recorders, u disk, computer motherboards, etc.), in the small household appliances, snack foods, frozen food cosmetics, health products There are also applications in the areas of wine, carton trays, etc. In southern China, electronic and small household electrical appliance manufacturers are more developed in the printing and packaging industry. Therefore, there are many miniature corrugated packaging applications in the South.

In foreign countries, the application of miniature corrugated packaging is more extensive. In addition to these fields, applications in the fields of alcoholic drinks, small appliances, shoes, hardware tools, microelectronics computer software counters, and fast food sales are also very common. More than 30 companies such as Haier and Motorola Kodak Siemens SONY have summarized the competitive advantages of miniature corrugated packaging in the eyes of users as low cost, good seismic performance, and high-compression-strength printing.

For the carton industry, the market is gradually becoming wider and smaller. Now the industry has created a trend to use miniature corrugated packaging to produce miniature corrugated packaging as a new economic growth point for cartons. More and more users are beginning to realize the advantages of miniature corrugated packaging. The production of miniature corrugated packaging has great market potential in the direction of market development. In addition, many export products have selected miniature corrugated packaging as the outer packaging.

1. Appliance industry

The use of miniature corrugated packaging in the household appliance industry is mainly the direct packaging of products in E-boxes or the use of BE-boxes instead of the traditional A- and B-boxes. Companies such as Haier, Philips, Kelon, BenQ, Changhong, Lenovo, and Supor TCL are all using miniature corrugated packaging.

2. Frozen food industry

Frozen foods such as ice cream now also use miniature corrugated packaging. On the one hand, it is required to print beautifully as a sales package, and on the other hand, it is required to be able to withstand low temperatures as an inner package. Nestle's Moonlight Box and Lu Xue's dry snow, Ailaifaxi's Eight Ice Cream and other products are all in miniature corrugated packaging.

3. Mobile phone industry

Miniature corrugated packaging is favored by mobile phone manufacturers due to its advantages such as high compressive strength, moderate and medium performance. Companies such as Motorola, Datang Telecom Capitel and Nokia are all using miniature corrugated packaging.

4. Cosmetics industry

Now the cosmetics industry is also commonly used in miniature corrugated packaging. The use of miniature corrugated liners like LANCOME has become very common, and there are now products that use miniature corrugated packaging as direct packaging.

Key Technologies for Making Miniature Corrugated Packaging

E楞 corrugated packaging production is now common. Almost all corrugated cardboard manufacturers can produce, E楞F楞 and G楞 packaging box in the domestic processing technology is also quite mature. The specific approach is to use the traditional processing technology: a paper printing a miniature corrugated paper, a die-cutting a paste box. Using this technology, manufacturers who make both color box and corrugated cartons have advantages as long as the production process is adjusted to use existing offset printing and post-printing corrugated box equipment to produce new equipment without production cost. Higher, because the face paper and corrugated paper are processed independently and require the synthesis of thicker face paper. The general basis weight is higher than 2OOg/m2, otherwise it is easy to dew and the lamination speed is very slow. Although this process is not ideal, it is currently very practical. For the quality control of miniature corrugated packaging boxes, the following points should be made during production.

(1) In order to improve the compressive strength of mini-corrugated packaging boxes, the quality of the base paper for making micro-corrugated cardboard is very high. Kraft paperboard and core paper quantitative comparison calfskin paperboard best not more than 1 50g/m2 core paper does not exceed 1 05g/m2 thickness should be uniform ~ better toughness better strength. Code white kraft paperboard, American Huihao stone kraft paperboard core paper and domestic high-strength paper can meet the production requirements. Miniature corrugated boxes are beautifully printed using low-quantity white cardboard and corrugated paper to produce corrugated cardboard with a basis weight of 300-550g/m2. Due to the increase in the unit utilization of paper. The overall cost of packaging has dropped. The weight and thickness of the paperboard reduces the transportation costs and stacking space of the goods. The most important is that the mini-corrugated box saves the cost of transporting and selling two functions of packaging as a secondary package. In the manufacture of micro-corrugated cardboard, some additives should be added to the adhesive to improve the strength of corrugated board.

(2) The use of traditional technology to complete the mini-corrugated box veneer veneer process is very critical veneer machine is best to choose the machine that can not only corrugated but also can jam the paperboard. Currently Taiwan's Caiyi Machinery Industry Co., Ltd. and Qingdao Micron Machinery Co., Ltd. automatically paste The dough machine has this function. If a laminating machine that can only use corrugated paper is used, since the corrugated cardboard design is minimal until it reaches E, it is better to require the equipment manufacturer to improve the parallel accuracy of the cot and to reduce the vibration of the machine and improve the pressure of the paper belt. Flatness. After laminating the belt, it is best to increase the pressure on the belt. Increase the delivery speed. So that the paperboard after pressing is flat. The viscosity of the adhesive is about 40s. To ensure that the corrugated paper and printing surface paper are firmly bonded with a minimum amount of adhesive, the solid content of adhesive per square meter should not exceed 10 grams. The small amount of adhesive can prevent dew, if the customer allows it to properly increase the ration of printing surface paper can also reduce the dew. When facing, the corrugation must be perpendicular to the direction of the fiber of the printing paper. This will not only reduce dew but also increase the strength of the box. And the box is not easily deformed.

(3) G, N, F corrugated board printing is mainly based on offset printing technology. Direct offset printing on micro-corrugated cardboard has the following advantages: The packaging material used has a flexible color effect. High printing quality. Shorten the cycle of product production and increase production efficiency. Significantly reduce printing costs, eliminating the cost of coating and reducing other additional costs.
