Glazed Flower Pots are pottery pots that have been glazed. The pottery pots that have been glazed combine the advantages of clay pots and plastic pots. The surface will look smoother, the color will be more gorgeous, and then it will look more attractive.
The Ceramic Glazed Plant Pots, also called Glazed Flower Pots, are relatively heavy and not easy to tip over, but they are also difficult to move. They will also crack in a frosty environment. They are breathable and drainable. They are not as good as pots.
Glazed flower pots have poor air permeability, but they are beautiful in appearance and have a variety of choices.
Porcelain basins come in various styles and colors, so there are a lot of them circulating on the market. However, one of the biggest disadvantages of porcelain basins is that they are not breathable. Therefore, when choosing a porcelain basin, you should choose a hole punched at the bottom, and it is best to install a vent pipe.
First, the corrugated board processing process corrugated board processing technology is divided into two categories.
1. Production Process of Automatic Corrugated Cardboard Production Line The corrugated board production process is widely used, with advantages of large production volume, large carton forming volume, and good quality of the crucible type. The corrugated board produced by this process is usually made into cartons through processes such as water-based printing, slotting, sticking, and forming. The cartons produced by this process are mainly used for transport packaging.
2, the production process of semi-automatic corrugated board production line The corrugated board production process is to print the first paper, and then with the good corrugated paper, paperboard for coupling. The corrugated paperboard produced by the process is conventionally made into boxes by die-cutting indentation, adhesive nailing and the like. The carton produced by this process has good molding quality and good surface treatment effect. The cartons produced by the compromise process can be used for sales packaging.
Second, the conventional carton printing methods General carton printing methods are mainly flexo, offset and screen printing three.
1. Flexo Printing Corrugated Boxes Conventional flexo printing corrugated box processes are printed directly on corrugated paperboards using water-based inks, so it was also the case that the process was watermarking.
Flexo printing has the following features:
(1) Large-format, wide-format flexographic printing presses have a maximum width of 2.5 to 2.8m.
(2) The price is low, flexographic prints are very resistant to print and can be reused; humor prices are also lower.
(3) It can be linked to production, such as printing, slotting, indentation, ordering (sticking) boxes, baling and so on.
(4) Less carton strength is reduced. Since flexo printing is light press printing, there is little effect on the strength of corrugated cardboard.
(5) The printing accuracy is not high, the number of conventional offset printing screens is 175 lines/inch, while the number of conventional screen printing lines in flexo-printing boxes is 35~65 lines/inch, which is a low-precision printing method, and is most suitable for printing text lines and four colors. Although the image printing quality has improved in recent years, there are still limitations.
(6) There are difficulties in making plates, text lines are easy to make, and four-color images are more difficult to make.
(7) The stability of printing quality is not good, mainly reflected in the darkness of the printing ink.
The flexographic plate direct printing process is suitable for the production process of the first type carton, and is currently widely used in the carton factory in China.
2, offset printing corrugated cartons conventional offset printing corrugated cartons used indirect printing, that is, printing cardboard box surface paper, and then paste the printed surface paper to the corrugated font size class. Due to the relatively high resolution of the PS version, very fine printing patterns can be printed. The vast majority of high-grade corrugated cartons used for sale packaging in China are offset printing products.
Offset printing corrugated boxes have the following characteristics:
(1) It is not suitable to use paperboard linkage production line. It is only suitable for single-faced corrugating machine and the production efficiency is low.
(2) Limited format, generally smaller than flexo print carton format.
(3) The printing product is very fine, and the number of screens can reach 150~200 lines/inch.
(4) Plate making is easy. It is a conventional plate making of PS plate.
(5) Can finish the surface decoration, such as laminating, polishing and so on.
(6) High printing costs.
(7) The printing quality is relatively stable.
3, screen printing corrugated box screen printing corrugated box process is a direct printing method.
Since the ink ratio of the screen plate is proportional to the hole pitch of the screen, the resolution of the screen printing is not high, the image accuracy is low, and the number of conventional screen lines is 60 to 80 lines/inch.
Screen printing corrugated boxes have the following characteristics:
(1) It is not suitable for the linkage production line and the production efficiency is low.
(2) The printing format can be large or small.
(3) The printing can be completed before pairing and boxing, and printing can also be performed after pairing and boxing.
(4) Suitable for printing non-fine products. The screen printing ink is thick, so its color saturation is high and the visual effect is strong, especially the spot color printing is better in the field.
(5) Plate making is easy and plate making cost is low.
(6) Low printing costs.
(7) The printed matter is relatively stable.
Third, the new printing box method 1, plastic gravure compound carton process using single-sided corrugated production line, if the face paper printing is completed after the need to cover the light film, and the production volume is larger, you can not print on the surface paper, but use The gravure printing method completes the gravure printing in the plastic film, cuts and adds the white base coating, then combines the factor ah good plastic film with the facial paper first, then according to the conventional carton forming craft to regret the horizontal box.
The characteristics of this process are:
(1) The cost of carton production is low. When the production volume is large, such a process can greatly reduce the printing cost of the tissue paper and the material cost of the tissue paper. Because the noodle paper does not need to be printed, non-coated white paper can be used, so that the cost of the noodle paper is greatly reduced.
(2) beautifully printed. Because plastic gravure is used, the printing effect can be comparable to that of offset printing.
It is necessary to pay special attention to the fact that in the process of plate making, it is necessary to fully consider the dimensional change and deformation of the plastic film. Otherwise, the carton face paper will be misaligned with the lower cardboard.
2. Coated paper gravure composite carton process When the production volume is relatively large, no film is needed, and the printing effect is good and the cost is low, this process can be used.
The process is to use a paper gravure printing machine to print thinner coated paper, and then composite this finely-printed coated paper with ordinary slagboard or boxboard paper. The whole is used as cartonboard paper, and then it is used for confrontation and normal carton forming. Processing.
The characteristics of this process are:
(1) The cost of carton production is low. The main reason for the reduction in cost is to convert whiteboard paper to low-weight coated paper in combination with cheap linerboard, which reduces material costs.
(2) beautifully printed. Paper gravure printing is very beautiful.
(3) Gravure printing plates are more complicated and costly, and are not suitable for printing carton products that are often revised.
(4) The operation and control methods of the printing process, such as the face-to-face paper compounding and the box making, must be carefully explored, accumulated, and reasonably implemented, otherwise it is easy to cause an increase in the reject rate.
3, direct offset corrugated cartons process corrugated cartons direct offset process is currently relatively mature in foreign countries, it is the corrugated board directly on the special offset press for printing. Suitable for processing thin corrugated boxes.
The process can not only guarantee the good moldability of the carton, but also can complete the exquisite glossy paper printing. However, the printing press used is relatively expensive. At present, it is not yet in line with China's demand standards, and it is not suitable for the carton industry in the near future. Adopted, but in the next few years, this process may become the new development direction of high-grade carton printing in China.
4. Flexo Preprinting and Gravure Preprinted Corrugated carton technology has developed rapidly this year. Both processes are first to use web to print face paper, and then to complete the production of corrugated cardboard in the automatic corrugated board production line. Carton printing quality and molding quality are relatively high, but the investment is relatively large and it is not suitable for small batch production.
In suffocating the industry in the country, the three kinds of conventional printing methods should be used more generally and become the mainstream method of corrugated box factor. The new type of printing box method, due to the hot spots of equipment, materials, processes, operations and other technology has not yet been fully grasped, the investment is relatively large, the promotion of the difficulty is still relatively large. However, in order to improve the quality of cartons, reduce the total cost of the cartons, obtain maximum profits, and increase the competitive advantage in the market, it is imperative to adopt a new type of box-making technology.
From the general development of the carton printing process, the plate making and printing technology of the flexographic plate printing corrugated box process needs to be improved as a whole. The plastic gravure printing, the carton gravure printing and the web offset printing process need to be promoted and improved. Direct offset printing and preprinting Corrugated box production process should also arouse our concern.
