Factors Affecting Residue of Pharmaceutical Packaging Material in Printing Process
 1, the impact of supplies on the packaging of drug packaging
The release of ink itself to pharmaceutical Pharmaceutical Packaging Material. The better the solubility of the drug packaging material to the resin in the ink, the worse the release of the resin to the drug packaging material. Different ink on the release of pharmaceutical Pharmaceutical Packaging Material is different, especially in some small ink production enterprises to produce low-end ink, due to the use of lower-grade resin and paint, the release of drug Pharmaceutical Packaging Material is poor, the income The amount of drug Pharmaceutical Packaging Material will be larger. Therefore, the flexible packaging enterprises in the choice of ink before the best ink manufacturers to understand its ink products on the release of pharmaceutical Pharmaceutical Packaging Material in order to make the appropriate treatment. In addition, the same ink system in a variety of color ink Pharmaceutical Packaging Material release is also different, in which the red ink, black ink drug packaging material release is poor, mainly due to red ink, black ink pigment particles smaller than The surface area is large, the adsorption capacity is strong, and the evaporation speed of the mixed medicine packaging material in the ink. Ink will be mixed with a variety of pharmaceutical Pharmaceutical Packaging Material, known as mixed pharmaceutical Pharmaceutical Packaging Material. The volatilization rate of the mixed pharmaceutical packaging material has a greater effect on the final packaging of the flexible packaging. If too much use of ink in the slow dry pharmaceutical Pharmaceutical Packaging Material, then the final packaging of flexible Pharmaceutical Packaging Material will be even greater. Therefore, it is very important to choose and design the types and proportions of the Pharmaceutical Packaging Material in the ink.
2, graphic design and product structure on the residual packaging of pharmaceutical products
In general, in the flexible packaging graphic design should not be designed too much color, because if the ink layer is thick, there may be rapid drying of the surface ink, thus hindering the ink inside the packaging of drug packaging problems, and ultimately Resulting in increased packaging of flexible Pharmaceutical Packaging Material. Can use spot color ink to prevent the printing of the local ink layer is too thick, so as to effectively reduce the packaging of flexible Pharmaceutical Packaging Material.
If the same plate on both a large area of the field, there are very shallow mesh pattern, to control the packaging of drug packaging is extremely difficult. Because when the mixed drug packaging material drying too fast, the shallow net will be blocked version, and reduce the drying rate of mixed pharmaceutical Pharmaceutical Packaging Material, will cause a large number of drug Pharmaceutical Packaging Material remain. Therefore, the plate should try to avoid this design.
 In the design of flexible packaging product structure, as far as possible the poor barrier film as a printed layer, and then with a higher barrier barrier and heat sealing layer composite, so as to avoid contamination of the packaging.
3, concave process on the residual packaging of pharmaceutical products
Drying conditions. Gravure machine oven structure, ventilation, air temperature and other factors determine the drying efficiency of printing and drying effect.
Today, the gravure drying system is constantly improving, such as imports of gravure press the last color group to use more than two ovens, domestic gravure machine will extend the length of the oven. In addition, some gravure machine manufacturers also implemented an effective partition within the oven, divided into the upper and lower parts, this design can be part of the lower part of the drug Pharmaceutical Packaging Material, high gas emissions, the upper part of the drug Pharmaceutical Packaging Material Low gas content of the hot air secondary circulation, greatly reducing the printed matter of the packaging of drug packaging.
Printing speed; printing speed, determines the length of the print drying time. In order to effectively control the soft packaging of drug packaging material residue, should ensure that the printed ink layer is fully dry, the appropriate increase in printing speed.
Printing workshop humidity; printing workshop humidity for the packaging of drug packaging also has a great impact, for two reasons: First, the water will enter the ink in the ink to reduce the ink in the packaging of volatile materials; the second is the air A large amount of moisture also inhibits the evaporation of pharmaceutical Pharmaceutical Packaging Material in the ink. In general, the humidity is doubled and the drying speed of the ink is nearly twice as fast. So in high humidity conditions, should try to reduce the printing speed, and try to avoid ink and air contact to ensure that the ink layer is fully dry. The humidity of the printing workshop is generally controlled at 50% ~ 65%.
Printed products should be placed in a ventilated place a day or two after the composite.
