Packaging bags design how to save costs
Flexible packaging bags gravure industry in petroleum products as the main raw material, enter the energy-intensive industries.Countries have already carried out vigorously regulation environment quality in the path, flexible packaging gravure industry want to move forward, you must find a green production development path.
Flexible packaging gravure and composite processing, gravure press and composite machine in the discharge of waste gas containing organic solvent emissions system make the non-renewable resources waste, also caused severe environmental pollution.In the process of using organic solvents in volatile can cause indoor pollution and production safety.Under the present social background, flexible packaging gravure industry green production is the only way to do it.
VOCs control, there are a few points
1, to reduce the loss
The process of flexible packaging, raw and auxiliary materials, the cost of inks and adhesives almost 70% ~ 80% to the total cost of the printing quality, materials, energy and waste of time (such as in volume, change process), will result in an increase in costs, for the production and operation of an enterprise must try to minimize the waste in production, can effectively reduce the cost.
Flexible packaging gravure boot debugging and misregister generated during the production of waste, the material loss caused by the biggest, if the fine adjustment of operation and process steps are closely linked, will be able to get a stable, predictable scrap value.At present, the domestic existing gravure equipment manufacturing enterprises based on the rapid preliminary alignment success, the latest technology, such as high precision tension control makes the gravure equipment cutting losses, restart the loss (alignment), changing single loss, restart storage before order loss, slow down to tiny mistakes such as the loss and loss, and even in some ways superior to the international advanced level.
2, the auxiliary time of operation
Relatively advanced intaglio printing equipment by adopting a series of new technology, greatly shorten the assistant time operation, for example, version, edition, inking integration operation, can the offline version of roller and ink tank cleaning;Quick inking system can be organic solvent from solvent room directly into the ink plate, for the quantity control by printing ink viscosity control instrument;Without tooling replacement sleeve roller technology, reduce Labour intensity, shorten the replacement time;Quick change of the scraper of scraper technology to achieve the rapid replacement;Laser on the edge system, safety chuck fast clamping system achieve rapid fluctuate;Fault display and alarm system to help maintenance personnel to quickly diagnose and to deal with failure;Historical fault alarm indicator system can reduce the time of the maintenance personnel some troubleshooting.
3, the dosage of the printing layout will be reduced
A, tinted marking, cutting, bag making, marking, network signals, etc should be reasonable use of its small size, color as far as possible, in order to reduce the wastage of the film or paper.
B, reduce the use of color version, the color ink, with primary colors as far as possible or fold instead of color, to save materials and printing ink usage.
C, reduce the number of color, optimization of layout design, reduce the overlap area of printing.
4, improve the efficiency and automation level, reduce the dependence on people
In recent years, the domestic machinery manufacturing level of ascension, domestic gravure equipment has been in constant innovation, and obtain effective results.At present, gravure press top speed has reached to 400 m/min, printing efficiency is greatly increased.And the automation level of high-speed gravure press also in unceasing enhancement, automatic fluctuate of technology, automatic cutting technology and the application of on-line detection device in intaglio printing equipment, reduce dependence on the operator, the equipment has greatly increased the production efficiency of the equipment.
