New development trend of the hottest micro tile co

New development trend of micro tile color box packaging

the packaging of small commodities is undergoing a change. The application trend of European and American countries shows that the folding carton, as the main packaging of consumer goods, is gradually replaced by corrugated color boxes with vivid graphics, exquisite printing, neat box shape and light weight. Since its introduction in 1990, the market utilization rate of micro corrugated has been rising. The United States has increased at a rate of 2% every year, and the share of Europe in 2004 is estimated to account for 12%. Moreover, it is mainly small corrugated such as F-type, G-type and n-type. At present, 30% of products packed in folding cartons can be replaced by micro corrugated boxes

China's micro corrugated board has just started, which 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. Compared with folding paperboard with the same gram weight, micro corrugated paperboard has better printing adaptability, higher stacking strength, stronger shock absorption performance and lower cost. The new micro tile carton face paper adopts light weight white paper, white card, color card, glass card and other materials to replace the imported high gram weight coated cow card required for card box production. In terms of environmental protection, corrugated products are easy to recover and regenerate, eliminating the soil burying requirements for coated paperboard

the growth of micro corrugated

corrugated boxes are widely used in the transportation and packaging of goods with good strength, low cost and light weight. The good compression and burst resistance of cartons comes from the corrugated core paper between the face paper and the lining paper. The larger the height and width of the corrugated type, the larger the volume of the carton and the greater the load; The corrugated shape becomes smaller and thinner, and the carton becomes a carton, but its physical properties exceed the solid carton with the same gram weight. The corrugated type is in the order of size, and the English letters are arranged as follows: D, K, a, C, B, e, F, G, n. The system from e to n is called micro corrugated

the disadvantage of corrugated boxes is that the printing is simple and there is no "eyeball" effect, because the face paper of cartons generally uses natural color box board paper, and the printing fineness is limited. In this way, the goods themselves need a small package. Cardboard boxes made of coated or uncoated Kraft linerboard are the most common. The cardboard boxes are inner packaging and the cartons are outer packaging

georgia Pacific is a professional carton manufacturer in the United States. After investigating the cardboard cartons on the market, they concluded that there are three problems with the cardboard cartons as the sales packaging of consumer goods: 1 The price of kraft linerboard base paper is high, and the printing and processing costs are expensive; 2. The printing of natural color Kraft linerboard is not bright; 3. The white paperboard is brightly printed, but the coating effect is not good, which is easy to produce folding cracks. Therefore, Georgia Pacific has developed a micro corrugated called cecorr, which is equivalent to type E in height. Since then, F, G and N corrugated with smaller height have appeared one after another

the micro corrugated box is beautifully printed, and the corrugated board with a ration of 300 ~ 550g/m2 is made of light-weight white board and low gram weight corrugated paper. Due to the improvement of the utilization rate of unit paper, the overall packaging cost is reduced; As the weight and thickness of paperboard are reduced, the transportation cost and stacking space of goods are also reduced. The most important thing is that the micro corrugated color box combines the two functions of transportation and sales packaging, and saves the cost of secondary packaging. Paper mills in Europe and the United States have specially designed light-weight white paper with a weight of less than 200 grams for fine tile cartons, such as kemiart coated kraft from M-real in Finland, CKB from Storaenso in Sweden, and white paper from visylite (R), Westvaco, St. Laurent and IP in the United States. Whether it's coated paper or white cardboard, the smooth surface and good inking of corrugated board make the printing color full, the graphics and texts clear, and the luster dazzling. Micro corrugated color boxes not only bring benefits to carton and carton manufacturers, but also bring new business opportunities to consumer goods manufacturers

in the functional development of micro tile cartons, a rapid and convenient sealing system has been applied. Its advantages include:

-- unified and beautiful appearance

-- the seal is firm

-- better protect the contents during transportation

-- the seal is fast and easy to be removed

breakthrough in printing technology

storage and transportation packaging has always been based on field or line printing with simple colors. Today, consumers expect businesses to print the original appearance of products on the outer packaging and understand the quality of products through high-quality outer packaging. After continuous efforts, packaging manufacturers are achieving this goal

at first, the formation of micro corrugated adopts the offset pre printing and veneering process, that is, color is printed on the white flat paper first, and then it is mounted and compounded with corrugated cardboard on the veneering machine. The use of offset printing machine is because the four-color effect was better than any other printing form at that time, but the veneer composite would lose 10% of the corrugated height and reduce the strength of the carton. In addition, the veneering process is not suitable for light-weight facial paper below 200 grams, and the phenomenon of "washing board" is easy to occur when corrugated board is compounded

with the progress of flexographic pre printing and post printing technology, corrugated board direct printing has entered the territory of flexographic printing. Flexographic printing can basically achieve colorful color effects and overcome the common defects of washing board in corrugated printing. DuPont's thin plate technology and the fine light printing effect of boster 6-color post press make the printing of fine corrugated board more bright, and the ink coverage and contrast effect are close to offset printing, minimizing the technical difference between corrugated board printing and folding board printing

products are displayed through storage and transportation packaging, and the design concept and market demand of products are publicized, which promotes the rise of offset press direct printing corrugated board technology. Offset four-color printing has traditionally been regarded as the most ideal printing configuration. After continuous refinement of corrugated board, G-type and n-type have come to a successful end for offset direct printing. The existing ROLAND700, 900 and KBA Planeta offset printing machines can directly print micro corrugated board with a little adjustment. There is no washing board phenomenon, and the strength of the board is not reduced due to corrugated deformation. The successful application of offset post printing technology has finally realized the replacement of corrugated color box with hard paper card box. Compared with other printing experiments such as tensile test, impact test and change test, many domestic packaging manufacturers have imported four-color offset printing machines and flexographic printing machines, which provide the necessary basis for color printing for card boxes to turn to corrugated

offset direct printing has become the main printing method of micro corrugated boxes. Flexo direct printing will mainly be thick cartons, but flexo printing will also be used for thin tiles with relatively simple shapes and patterns and large batches. The top quality corrugated board uses the composite method of offset paper first, and then facing and mounting

the matching of front and back equipment

the trend of changing cardboard boxes into fine corrugated color boxes for consumer goods packaging has prompted packaging manufacturers to quickly respond to the new requirements of customers' color and cardboard structure. The practice of European and American carton factories is to increase micro corrugated cardboard lines and transform folding boxes into corrugated boxes according to actual needs

at present, the micro corrugated box packaging used for small commodities in China is mainly e-corrugated. The corrugated board is produced by the traditional guide claw single-sided machine. After offset printing, the veneer is compounded, and the front cardboard equipment obviously cannot meet the needs of direct printing by offset printing machine. Corrugated and carton in the domestic packaging industry are often operated separately. Corrugated carton factories do not produce cartons, carton factories do not produce corrugated, and the front and rear processing of micro corrugated carton production are not combined. 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 improve box making machinery to promote the development of micro corrugated boxes. Jiangsu Changfeng Packaging Co., Ltd. introduced Italian high-end corrugated production line, which can produce large corrugated board and process small corrugated board, opening the precedent for the production of micro corrugated color cartons. Jingshan Light Machinery Co., Ltd., the largest carton equipment manufacturer in China, has also started the localization production of micro corrugated board line. At the same time, the micro tile color box should also be equipped with the corresponding rear indentation, die cutting, box sticking lubrication system, and the pipeline leads to each rotating joint and moving part process, so as to ensure that the carton is beautiful, neat, firm and solid. p>
