Environmental protection awareness of large flexible packaging companies (Chinese)

For example, flexible packaging manufacturers with annual sales of 50 million U.S. dollars are roughly 55% to 60% of total sales, after deducting incidental expenses (including about employee's wages, energy, rent and scrap costs), flexible packaging manufacturers The profit is roughly $1.5 million, which is equivalent to 3% of sales. One of the major problems that flexible packaging manufacturers have to face is waste. Although up to 18% to 20% of waste comes from a variety of reasons (such as scratches, chromatic aberration, shrinkage, flying ink, paper breaks, pleating, etc.), Waste generated during register adjustment is the main cause of waste. Reducing waste not only means savings for the packaging industry, but also reduces non-productive time.

Flexible packaging manufacturers must control many major cost points in the actual production process in order to obtain maximum cost efficiency. What kind of development and innovation should print equipment manufacturers make to ensure that the flexible packaging industry can meet the challenges of today, tomorrow and the future? Flexible packaging manufacturers should be allowed to improve their internal cost control and adapt to market prices by using leading technologies that have been tested by equipment manufacturers. .

Excavating equipment potential is an integral part of flexible packaging manufacturers' continuous development and optimization of operational practices and process steps. As an equipment manufacturer, we maintain close ties with the flexible packaging industry all over the world, and have carefully studied the needs of packaging and processing industries to increase internal efficiency.
We meet the future needs of the packaging industry by the following measures:
1 Minimize the waste of film and ink and effectively increase profits;
2 Reduce the preparation time for commissioning to the shortest, so that short-lived and long-lived printing is no longer a contradiction;
3 By reducing the time consumption and manually adjusting the work, the operator can pay more attention to print quality.

Flexible packaging manufacturers hope that the shorter the debugging time of equipment, the better. With the maturity of electronic shaft printing machine manufacturing technology, this desire has become a reality. Compared with the traditional gravure printing machine, the electronic axis system can significantly reduce the commissioning time for new prints. In addition, if the flexible packaging manufacturer has a nine-color electronic shaft printer and the average color is seven colors, then the two remaining printing units can be used for preparation, including inking and running the squeegee, which makes debugging. The preparation time was reduced by 20% on the basis of the above. Another advantage of the electronic axis press is that it can reduce the plate change time to about one minute.

Assume that the average annual sales of flexible packaging manufacturers are 50 million US dollars, then the ink cost should be close to 5 million US dollars. Calculating about 20 products per day, about 2400 kilograms of the diluted ink was recovered from the printing press, 80% of which was recycled and sent back to the press. The diluted ink is calculated at US$2.8 per kilogram and the annual cost is US$336,000.

Saving ink can significantly increase company profits. Our solution is to use a new shallow ink tank in which the floating roller is in close proximity to the plate cylinder. Shallow ink tanks can reduce the total amount of ink needed for the production cycle to 7 liters, reducing the amount of ink that needs to be recycled. In the above example, the amount of ink recovered decreased from 2400 kg to 840 kg, which reduced the total cost of ink used for processing to 118,000 US dollars. This can be seen. Savings of $218,000 can be achieved with only one ink purchase. We are now designing a new type of machine suitable for short live printing, and the ink supply system will have less ink circulation.
