The hottest prospect of micro corrugated developme

  • Detail

Looking forward to the development prospect of micro corrugated

the packaging of small commodities is undergoing a change. The application trend in Europe and the United States shows that as the main packaging of consumer goods, folding cartons are gradually replaced by corrugated color boxes with vivid graphics, exquisite printing, neat box shape and light weight

compared with the folded paperboard with the same gram weight. It has better printing 1. Generally speaking, it has higher adaptability, higher stacking strength, stronger shock absorption performance and lower cost; The new micro tile paper box is made of light weight white paper, white card, color card and glass card. Replace the imported high gram weight coated cow card required for card box production; In terms of environmental protection, corrugated products are easy to be recycled, avoiding the requirement of burying coated paperboard

since the advent of micro corrugated in the 1990s, the market share has been rising. The annual wear rate in the United States has increased by 2%, and the share in Europe in 2004 is estimated to account for 12%, and it has shifted to small corrugated such as F-type, G-type and n-type. Micro corrugated board in China has just started. It is limited to the production of e-type corrugated. In terms of paper quality and grade, there are few varieties and low grades, which need to be vigorously developed

the growth of micro corrugation - to achieve the "eyeball" effect, the corrugation types are arranged in the order of large D \ jll~ in English letters as follows: D, K, a, C, B, e, F, G, N, from e to n is called micro corrugation.

corrugated boxes are widely used in the transportation and packaging of goods for their good strength and low cost, but the disadvantage of corrugated boxes is that they are simple to print. There is no "eyeball" effect. The surface paper of cartons generally uses natural color carton board, so the printing fineness is limited. From this point of view. The commodity itself needs a small package. Cardboard boxes made of coated or uncoated Kraft linerboard are the most common. The reliability of all hard devices. The box is the inner package and the carton is the outer package. The good compression and bursting resistance of cartons comes from the corrugated core paper between the surface paper and the lining paper. The larger the height and width of the ridge, the larger the volume of the carton. The greater the load. The ridge becomes smaller and thinner. Cartons become cartons. However, its physical properties exceed the solid cartridge with the same gram weight

Georgia Pacific, a professional carton manufacturer in the United States, concluded after investigating the cardboard boxes on the market that there are three problems with the cardboard boxes as the sales and packaging of consumer goods: first, the price of kraft linerboard base paper is high, and the printing and processing costs are expensive; Second, the printing of natural color Kraft linerboard is not bright; Third, white paperboard printing is bright, but the coating effect is not good, easy to produce folding cracks. Therefore, Georgia Pacific developed a micro corrugated called cecorr, which is equivalent to type E in height. thereafter. F, G and N corrugated with smaller height appeared one after another

micro tile color box is beautifully printed. Use light white paperboard and low gram corrugated paper to make corrugated paperboard with a ration of 300 ~ 550G per square meter, Due to the increase in the monthly profit rate of falling paper, the overall storage of packaging decreased, and the weight and thickness of paperboard decreased. The transportation and stacking space of goods also decreased. The most important thing is the micro corrugated color box, which integrates the transportation and sales of packaging into one. The cost of packaging the second engine is also saved. Paper mills in European and American countries have designed light-weight white paper below 200 grams for fine corrugated boxes, such as kemiart 浍 buniuka of M-real in Finland CKB of Storaenso in Sweden, white cardboard of visylite, Westvaco, stlau REM and LP in the United States, etc.: whether it is coated paper or white cardboard, the smooth surface and good inking of corrugated cardboard make the printing color full, the graphics and texts clear, and the gloss dazzling. The micro corrugated color box not only brings benefits to the carton manufacturers, but also brings new business opportunities to consumer goods manufacturers

breakthrough in printing technology -- overcoming the defects of "washing board"

at first, the micro corrugated molding chestnut was pre printed by offset veneering technology. That is, first print color on white flat paper. Then use offset printing machine to print on the opposite sheet of corrugated board at the veneer base. The reason is that the four-color effect was better than any printing form at that time, but the veneer veneer veneer veneer veneer would lose 10% of the corrugated height. In addition, reduce the strength of cartons, The veneering process is not suitable for light-weight facial paper with less than 200g. The phenomenon of "washing board" is easy to occur when the tile and paperboard are reset

with the progress of flexographic pre printing and post printing technology, corrugated paper plate is directly printed into the territory of eight flexographic printing. Flexographic printing can basically achieve colorful color effects and overcome the common "washing board" defects in corrugated printing. DuPont's thin plate technology and boster's 6-color post printing creak fine printing effect make the printing of fine corrugated board more bright. The ink coverage and contrast effect are close to amine printing, which minimizes the technical difference between corrugated board printing and folded board printing. In the past, storage and transportation packaging has always been based on field or line printing with simple colors. Now, Xiao Fei expects businesses to print the original appearance of qualified products on the outer packaging, Understand the quality of production through high-quality outer packaging - shock the products through storage and transportation packaging, publicize the product design concept and market demand, and promote the rise of offset press Direct Printing Bureau 1 corrugated board drum technology. Offset four-color printing has traditionally been regarded as the most ideal printing configuration. Corrugated board has been continuously refined, G-type and n-type put a successful end to offset direct printing. The existing ROLAND700, 900 and KBA Planeta offset printing machines can directly e-Brush micro tile board with a little adjustment, and there is no "washing board" Phenomenon. There is no corrugated cross type to reduce the strength of the paperboard. The successful application of the post printing technology of glue printing makes the corrugated color box replace the cardboard card box, and finally realizes that many domestic printing and packaging manufacturers have imported four-color offset printing machines and mulberry plate printing machines, which provides the necessary basis for the card box to turn to corrugated color printing

offset direct printing has become the main printing method of micro corrugated cartons. Flexo direct printing will mainly be thick cartons, but the shape and pattern are relatively simple Flexographic printing will also be used for large quantities of fine tiles: the corrugated board of top quality uses the composite method of first offset paper and then paste face collection

the problem faced by micro tiles - the matching of front and rear equipment

the trend of changing the packaging of consumer goods from cardboard boxes to fine corrugated color boxes urges packaging manufacturers to respond quickly to the new requirements of customers for leopard color and cardboard structure. The practice of European and American old bandit box factories is to increase micro corrugated cardboard lines, Change the folding box into a tile box according to the actual needs

at present, China's small commodities are mainly packed with E-shaped corrugated boxes. Corrugated boards are produced by traditional guide claw single-sided machines. The friction and wear performance of parts and components in mechanical equipment is determined by factors such as material, working state, contact mode and environmental conditions. The front cardboard equipment obviously can't meet the needs of direct cutting by offset printing machines. Corrugated and cartons in the domestic packaging industry are often operated separately, Corrugated box factories do not produce cartons. Carton factories do not produce corrugated. There is no end to the front and back processing of micro corrugated box production. In the face of the rapid development of micro corrugated board abroad and the actual needs of China's packaging market, equipment manufacturers should step up the development of fine corrugated board lines and change the box machinery to promote the development of micro corrugated boxes. At the same time, the wrong tile color box should also be equipped with the corresponding back indentation, die cutting and box gluing processes to ensure that the carton is beautiful, neat, firm and solid

at present, a few domestic manufacturers have begun to take action. Jiangsu Changfeng Packaging Co., Ltd. has introduced Italian high-grade corrugated production lines. It can produce large corrugated cardboard and process small corrugated cardboard. Jingshan Light Machinery Co., Ltd., the largest carton equipment manufacturer in Hanoi that has opened the production of "type" corrugated color cartons, has also started the domestic production of micro corrugated cardboard lines. In short, micro corrugated has great potential, especially in China, Micro corrugated packaging has a large market space. With the increase of packaging column number and the continuous reduction of packaging cost required by users, more and more enterprises will use micro corrugated packaging
