Gravure printing plastic film quality standards and quality control on

Order to better achieve the above quality requirements, we have the following main aspects from the plastic film on the gravure printing process control:

1. To master a variety of Plastic Packaging Elements of film substrate technology

BO PP Is the most common printing substrates, the production process points is a typical plastic gravure production process; use polyamide or chlorinated Polypropylene Ink, the appropriate tension and the imprint pressure, dry temperature control under 80 .

BO PA Printing points: BOPA film deformation is easy to absorb moisture. Therefore, the time of printing presses to ensure that humidity can not be too high (if not dehumidifying humidity of the environment is not suitable for print Nylon Film); not printed film can not undermine its original aluminum packaging film, printing immediately after opening, printing on nylon membrane preheating required (if the machine does not preheat device can be mounted in plate 2 color after the first color as the warm air out of use), preheating temperature of 50 ~ 80 ; printing tension should be appropriately reduced; pressure to moderate; ink adaptable, depending on the choice of product structure and, if cooking bags must be Select Cooking ink; India finished product must be sealed packaging, ripening into dry indoor storage complex, and compound as soon as possible.
