flexible packaging gravure industry in petroleum products as the main raw material, also belong to high energy consumption industries. In the face of strong state regulation under the background of environmental quality, flexible packaging gravure industry to sustainable development, it must find a green production development path.
to petroleum products as the main raw material, flexible packaging gravure industry belongs to high energy consumption industries. Compound during processing and the flexible packaging gravure gravure press and composite machine exhaust system emissions of waste gas containing organic solvent not only cause the waste of non-renewable resources, also can cause the pollution of environment. At the same time, in the process of using organic solvents in volatile can cause indoor pollution and production safety. In the current social background, the development of green manufacturing is the only way to flexible packaging gravure industry. Enterprises do a good job in VOCs control, adhere to the green development, can from the following several aspects to consider.
to reduce losses in the process of flexible packaging processing, 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, As in the volume, change) in the process of living thing , an adverse impact on the production and operation of an enterprise and the cost increase, so try to minimize the waste in production, can effectively reduce the cost.
in the production of flexible packaging gravure boot debugging and misregister biggest waste materials caused by the loss, if the fine adjustment of operation and process steps 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) , in single loss and restart storage before order loss, slow down the loss is quite low, even in some ways superior to the international advanced level.
reduce auxiliary operation time domestic technology is relatively advanced intaglio printing equipment by adopting a series of new technology, makes the auxiliary operation time were significantly shortened, for example, on the edition, inking integration car implemented on 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, labor intensity is reduced, replacing time shorten; Rapid change the squeegee technology can realize the rapid replacement of scraper; 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.
through the printing layout to reduce the dosage of the
( 1) 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.
（ 2) To reduce the color version, the use of color ink, with primary colors as far as possible or fold instead of color, to save version in the use of materials and printing ink.
（ 3) Reduce color number, optimization of layout design, printing area, Overlap rate) 。
to improve the efficiency and automation level, reduce the dependence on people
in recent years, as domestic machinery manufacturing level has increased, domestic gravure equipment has been in constant innovation, and obtained encouraging results. At present, gravure press top speed has reached to 400 m/min, printing efficiency is greatly increased. At the same time, the automation level of high-speed gravure press also in unceasing enhancement, automatic fluctuate of technology, automatic cutting technology and the application of the on-line detection device in intaglio printing equipment to reduce the dependence on operators, equipment has greatly increased the production efficiency of the equipment.
