Sanlu carton pre-printed cost solution example

Shijiazhuang Sanlu Group Co., Ltd. packaging and decorating plant is a branch of the Sanlu Group and specializes in the production of cartons required by the Group. At the end of 2002, Sanlu Group's packaging and decorating plant began to use gravure preprinting machines to produce color cartons. Two years of practice has proved that the preprinted production method fully satisfies the production needs of Sanlu's cartons.

Sanlu Group pays attention to preprints

In 2002, the headquarters of Sanlu Group required its subordinate packaging and decorating plant to increase the printing quality while expanding production. In 2002, liquid milk cartons had been placed on supermarket counters. The cartons' packaging must also be changed from simple transportation packages to sales packages. Colorful designs have become a magic weapon to attract customers' attention. General carton enterprises use color printing cartons are offset film, the advantages of this method is good printing quality, moisture resistance, but the carton compressive strength is low, and the printing color is inconsistent, because the offset printing plate can only print 2 at a time With tens of thousands of sheets, it is easy to cause inconsistencies in the color of the earliest printed cartons and the last printed cartons, so we began to pay attention to preprints.

Select preprint

Sanlu Group has more than 100,000 cartons per day. If you use offset printing, even the largest two-color machines will require 5 or 6 units at prices ranging from 600 to 7 million yuan. If you use imported multi-color large offset presses, you will need tens of millions of dollars for one machine. You need to purchase 3 sets of equipment to complete the task, and the price will increase to 100 million yuan. At the same time, you will need to increase the number of glazing machines, single-sided machines, and laminators. equipment. In addition, after the increase in equipment, it will inevitably increase the number of factory buildings and increase the number of operators. The number of personnel will increase by only 100. Although a small offset press requires less investment, it requires two cardboard pieces and one more tongue. The cardboard is wasted.

Through repeated calculation and verification, Sanlu Group's packaging and decorating plant believes that the production of cartons by preprinting is more suitable for the production of Sanlu cartons both in terms of cost and quality. In the end, the factory chose Xi'an Aerospace Huayang Printing Machinery Co., Ltd. to produce a five-color gravure preprinting machine with 1.65 meters. The first three groups printed yellow, red, and blue primary colors, and the fourth group printed black (barcode, small and small words). The group is covered with varnish, and the printed roll is laminated on the tile, which is fast and good. The corrugated boxes produced have high compressive strength, good printing quality, and consistent print colors.

Preprinted cost accounting

Sanlu Group Co., Ltd. packaging and decorating plant since the use of pre-printed, the production costs have been greatly reduced, which is due to the following aspects:

From the perspective of equipment purchase costs, the packaging and decorating plant spent RMB 4 million to RMB 5 million for Xi’an Aerospace Huayang’s gravure pre-printing machines, which not only cost moderately, but also saved the purchase of glossers, single-sided lamination machines, etc. Equipment costs.

In terms of production efficiency, production efficiency increases. The use of a gravure preprinting machine saves manpower and only requires more than 10 operators to achieve more than 100,000 to more than 200,000 cartons per shift. The efficiency is 7 to 8 times that of an offset press. In addition, the pre-printed large-format paper can be printed at high speed without stopping the machine, resulting in high efficiency and low waste.

Due to the high utilization rate of paper, there are fewer paper edges, which can effectively reduce costs. With the pre-printed production method, the 1.6-meter corrugated board production line can discharge 4 to 5 cartons, with only two paper edges. With an offset press, even the mainframe can only produce two cartons, and more paper is needed. side. Every time you reduce a few paper edges, you can save hundreds of thousands in a year.

Prepress production When printing in large quantities, platemaking costs are low. A set of printing roller costs more than 20,000 yuan, can print 1 million prints, and each edition can discharge 4, 5 boxes, 1 million prints is 4 or 5 million boxes, and the printing plate prints 1 million copies. Once chromium plating can continue to print, so a set of printing rolls can be printed to at least 6 million cartons, an average of only a few kilos of money each cartons, and offset printing, each cartons at least 4 to 5 cents.

Pre-printing can use water-based inks, and use glaze to replace the film. It can be printed once, and it is environmentally friendly and saves money.

Finally, the preprinting machine is fully computer-controlled, easy to operate, and the personnel requirements are not very high (the lead wage of the offset printing machine is generally 5,000 to 10,000 yuan), and the equipment is not easy to fail, and it is easy to adjust even if a failure occurs.

Preprinted scope of application

In general, Sanlu's use of the pre-printing process effectively reduced production costs, but this was mainly because pre-printing was suitable for bringing Sanlu's cartons to production. Manufacturers wishing to try pre-printing should pay attention:

* The most important thing is that pre-printing is not suitable for short-lived work, and the amount of off-printing cartons must reach at least 300,000;
* Secondly, printing and corrugated cardboard production lines, die-cutting, and other equipment before and after matching can make the pre-printing process maximize its effectiveness.
* As the preprint is printed on the pattern first, the cardboard in the wrong position is scrapped when the slit is cut. Therefore, the computer-aimed tracking system must be installed on the tile line, and the heating plate of the double-sided machine should be chrome-plated. Horizontal to rusty).
