As a "national advanced packaging company" Huaqing Guangzhou Enterprise Group, in the development of grinding two swords in more than ten years, after several investigations and explorations, after several successful failures, it has developed a temperature resistance of 180°C, l90°C, 200°C, 2l0°C, 220 ~C, 230 ~ C, 240 °C, 250 °C ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ We design, use domestic materials and produce in Guangdong, but its quality indicators can be comparable to DIC products whose price is several times higher than domestic ones.
For example, after filming of pharmaceutical aluminum foil coating, when the residual amount of solvent does not exceed 10.0 mg/m2, the residual amount of benzene solvent does not exceed 3.0 mg/m2 and the metal does not exceed 1 part per million, as well as easy oxides. Sodium thiosulfate 0.0lmL/L, titration to the end, add 0.25mL of starch indicator solution, continue to titrate to colorless, the other to take the blank solution in the same operation, the two consumption titrant does not exceed 1.5mL. Aluminum foil varnish (paint), as the name suggests, its main task is to give a single printing or multi-color printing precision finishing semi-finished products after coating, after the polishing to increase the surface hardness of printed products; have a certain degree of flexibility; improve the rate of genuine , enhance the added value of the product. Effectively ensure that pharmaceutical products are not affected by changes in the external environment. According to YBOO l32002 (composite film for pharmaceutical packaging, general rule for bags), it marks the integration of China's packaging products, especially pharmaceutical packaging products with international standards. The introduction of high temperature resistant aluminum foil varnish is another result of Huaqing Group's new varnish series. The main reference for the development of its products is: 1 Identification of infrared spectrum; 2 Appearance: Barrier properties (water vapour and oxygen) ); 3 mechanical properties; 4 composite bag thermal strength (double and multi-layer); 5 solvent residue; 6 bags of pressure resistance; (three sided bags and other bags); 7 bags of drop (bags and The total mass of the contents and the drop height); 8 Dissolution tests: (1) Heavy metals; (2) Easily oxides; (3) Volatile substances; 9 Microbial limits (Common composite membranes, bags, external use composite membranes, bags, suppositories) Composite film, bag); 10 Abnormal toxicity? YBBOO l 32002 requirements, the coating oil must meet l 80-250 °C to meet the pharmaceutical packaging film bag performance requirements. Otherwise easy oxide exceeds the standard. The printing ink ink film does not change color, does not fade, does not fade, does not sidelight (the valley is called rainbow and rewind). Transparent after glazing, good affinity with printing ink, especially good smoothness and smoothness, and will not suffer from die-cutting or film-formation after the glazing film is formed, and can withstand the embossing, Mechanical impact during drilling.
In order to guarantee the quality of Huaqing's temperature-resistant medicinal aluminum foil coating oil, in the production of the product, the solubility, hydrogen bonding force, surface tension, resistance, volatilization velocity, and evaporation rate are controlled, while the proper amount of wetting additive is introduced. It is beneficial to the affinity of the coating film to the printing ink ink film after coating. To realize the scientific standardization and standardization of aluminum foil varnish (also known as protective agent).
Huaqing's high-temperature medical series aluminum foil varnish is operated in the same way as traditional glazing technology, but only increases the temperature. Use clean materials, equipment, facilities, packaging containers, and use materials that can be recycled or recycled. The varnish does not decompose when the varnish reaches a speed of 50-200 m/min at a speed of 180-250°C or gravure. We have collected and sorted out a set of environmental protection control data in the design, production, printing, cutting, heat sealing and other technological processes. In particular, combined with the feedback from packaging and printing manufacturers, the paper comprehensively analyzed the failure phenomena, causes, and handling methods of the coating printing coating polish process in the coating process, and then distributed it to the user and related units for reference.
Huaqing pharmaceutical aluminum foil packaging gravure coating oil can reach YBBOOl32002 and other standards, the fundamental one is the results of pharmaceutical packaging and printing for many years to help each other.
