The packaging and printing industry has entered the era of rapid economic and technological innovation in the process of world economic integration. China’s accession to the WTO and the success of China’s economic restructuring have changed the packaging and sales of consumer goods and brought business opportunities to export consumer packaging. The export of high-grade color carton packaging products and domestic demand are increasing day by day. The development of high-end color printing and packaging will also be included in the focus, the development of environmental protection series packaging plan. Driven by this market, it has lost no time in developing direct-printing high-grade color miniature corrugated cardboard carton packaging, which can meet the export demand of the international market and meet the demand for domestic consumer goods packaging.
First, product features and performance
Due to its unique material characteristics and processing technology, direct offset printing is a direct innovation for high-quality color micro-corrugated board, which is an innovation in offset printing technology. Its printed pattern is also very beautiful. It was first used on 1mm cardboard. Offset printing has changed the production process in the past, followed by printing and shortened the production cycle. Its products have the following two major advantages. First, they have sufficient strength to enhance the protection function in product transportation. The weight of solid fiber board is 40% lighter, while the board strength is increased by 40%, and the weight of the paperboard product is reduced by 20%. Therefore, product protection functions with the same performance can be achieved with less packaging resources, and the consumption level of paper packaging materials can be reduced. The second is that the smooth surface can obtain more exquisite and vivid patterns than the flexographic printing, and the transport package replaces the sales package.
Second, the choice of miniature corrugated cardboard
Corrugated cardboard is the most important raw material in printing. It directly affects the printing quality of products. According to the technical characteristics of micro-corrugated cardboard, it determines the type and selection of materials.
Paper with g/m2 core paper (g/m2) (g/m2)
E楞180-300 95-190 135-230
F楞160-300 95-160 127-175
N/G楞160-330 80-160 80-135
Prism 楞 Height (mm) Thickness (mm) Postpress (mm) 楞 Distance (mm) Number of turns (per/m)
E楞1.10 1.40 – 3.5 313
F楞0.75 1.10 1.07 2.4 420
G楞0.55 0.80 0.78 1.8 550
According to the plant's equipment capabilities, choose F-type corrugated board, the material is: 185g/m2 repaint white card +90 g/m2 corrugated paper +140 g/m2 white cattle card
Third, the innovative and advanced products
1, product innovation
A. New design concept
The direct offset printing based on the practical principle of miniature corrugated cardboard packaging has given the vitality of the product, injected new functions for the development of consumer product packaging, met the needs of domestic and foreign customers for branded packaging color box, expanded the application of the product, and improved Added value.
B. Printing Method Innovation
This product uses an improved printing machine to print a thickness of 1mm cardboard, which not only achieves high-definition print reduction effect, but also can not make the micro-corrugated material to be deformed by pressure, thereby producing a low-weight, high-strength material for consumer product packaging.
C, material preparation
This product adopts imported heavy-coated white flour bovine card, which can reduce the deformation under the printing pressure and the difficulty of continuous feeding. Its heavy coating technology makes the color of the printed product full, and the lining of the cow card makes the cardboard have a certain pressure resistance and water resistance, so as to meet the requirements of the commodity packaging, and is more suitable for the application and promotion of the sales and transportation packaging.
D. Process innovation
In the past, corrugated board could only be directly printed on the flexographic printing machine, but the printing effect could not reach the level of offset printing. If you want to get the high-definition printing effect of offset printing, you can only use the process technology of printing first and then recycling. The development of direct offset printing micro-corrugated board technology has made up for this gap in the history of offset printing in China. It has changed the technological process for the packaging and printing of micro-corrugated cardboard. It is beneficial to the consumption of resources and materials to save materials, reduce production costs, and shorten the production cycle. Satisfying the requirements of all kinds of exquisite packaging designs is a new product for the upgrading of export packaging.
