Polyethylene film packaging products on supermarket shelves
In recent years, flexo printing has become more and more popular in the polyethylene film (LDPE) printing field as the environmental protection requirements of printing inks have become higher and higher, the films have become thinner and thinner, and the printing factories have been demanding the improvement of production efficiency year by year. Enter the stage of rapid development, and there are more and more applications in the printing field such as paper and laminated film.
Flexible polyethylene film prints are widely used in the fields of household papers, women's products, beverages, textiles, fruits, Food Packaging, etc., and can be printed using a unit gravure press or a satellite flexo press. In Europe, North America, and South America, nearly 100% of these products use flexo; in South Asia, flexo prints also account for more than 80%; in Northeast Asia, Japan and South Korea use gravure, while in China, Flexo accounted for 15% to 20%, the other is gravure.
But what is the lower cost of flexographic printing compared to gravure printing? There are many differences in the views of various parties. In this paper, some comparisons are made based on the data accumulated during the actual production of thin film printing. It is expected that relatively accurate answers will be found to guide domestic enterprises in selecting the type of printing presses. Through the comparison of fixed investment in equipment, fixed investment and maintenance cost of printing plates, printing plate cost and life, and printing operation cost, the author concludes that the cost of the unit gravure printing machine is low when the order volume is small. When the order volume is large, the cost of the wide-format satellite flexo press is low.
I. Comparison of fixed investment in equipment
At present, the mainstream suppliers of satellite flexo presses in Europe, such as Germany, Spain, Italy and other countries, a medium and high-end 1200mm width 8-color flexo printer prices 16 million to 20 million yuan; medium and high grade gravure printer supplier In Japan and Europe, the price is about 11 to 13 million RMB. It can be seen that a single flexo press is more than 50% higher than a gravure press alone in the investment cost of a printing press.
Moreover, each flexo press also needs to be equipped with many devices and spare parts, such as 20 to 30 anilox rollers (70 l/cm to 400 l/cm); 40 sets to 50 sets of plate sleeves, 3 sets to 4 sets of intermediate sleeves , a special sticker machine and so on. These supporting facilities require an additional investment of 5 million to 6 million yuan. Therefore, the fixed investment of an imported flexographic printing machine is probably equivalent to two imported gravure printing machines.
Second, the comparison of the fixed investment and maintenance cost of the printing plate library
The flexographic printing plate is a flat-sheet photosensitive resin plate, which is lightweight and easy to store. Generally, it is only necessary to separate the printing plates with a foam film, and then two corrugated cardboard sheets are used to protect the entire printing plate. The flexographic printing plate generally adopts a vertical layout. A square meter of space can store 10 sets to 20 sets of printing plates. A flexographic printing machine has about 800 to 1000 products in a normal turnover every year. It takes about 50 m2 for general storage of printing plates. You can. In addition, the anilox roller, printing plate sleeve, and intermediate sleeve of the flexo printing machine also need to be stored on the site, and it takes about 70m2 to 100m2.
The gravure plate cylinder is made of metal such as steel, copper, and chrome. The weight is about 25kg/root, and a set of 8-color printing plates is more than 200kg. Therefore, gravure plate storage generally uses high shelves, high and low forklifts are required for entry and exit, and a gravure printing machine generally requires a standard high shelf of 500 m2. Because of the high load-bearing requirements, the gravure library is almost the highest investment warehouse.
Whether it is a fixed investment in a warehouse or a routine maintenance cost, the flexo version is far lower than the intaglio.
Third, the printing plate cost and life contrast
The plate making fee of the flexographic plate varies depending on the width and the circumference, and the price is 10,000 yuan/set to 20,000 yuan/set, while the gravure plate has only 8,000 yuan to 12,000 yuan. Moreover, the average life span of flexographic printing is between 900,000 and 1 million impressions, while the gravure version can exceed 1.5 million impressions. In addition, the gravure can be re-used through de-plating treatment under severe wear conditions, which is unmatched by the flexographic version. .
Although these situations are related to the short development time and small scale of the current flexographic plate-making factory, it is very important that the price of the photosensitive material, the main raw material of the flexographic plate, remains high. The cost of printing plate accounts for about 1/3 to 1/2 of the printing plate's selling price. At present, the photosensitive resin plate is mainly supplied by DuPont and Flint two international companies. Its high market share also dominates the flexo market. price.
Of course, the flexo platemaking also has its advantages. The plate making cycle is short, only 0.5 days to 1 day. Compared with the gravure 3 days to 7 days, it can greatly improve the efficiency and meet the flexible delivery requirements of customers.
