铝箔袋生产制作对油墨的要求!
发布于:2020/03/10 在铝箔袋印刷中,苯超标一直是困扰厂家的一个难题。但如果使用水性凹印油墨,则能改变这种状况,减少残留溶剂对盛装食品的污染。为保证定做铝箔袋印刷效果,在使用的过程中,有七点注意事项可以参考。
In the printing of aluminum foil bags, benzene exceeding the standard has been a problem for manufacturers. However, if water-based gravure ink is used, it can change this situation and reduce the pollution of residual solvent to the food. In order to ensure the printing effect of customized aluminum foil bags, there are seven points for attention during the use.
①用水调节油墨粘度,一般控制在15~25秒。防止粘度过高,造成脏版、糊版。
① Adjust the viscosity of ink with water, generally within 15-25 seconds. Prevent too high viscosity, resulting in dirty version, paste version.
②使用水性油墨进行铝箔袋印刷时,PH值应控制在8.5~9之间。
② When using water-based ink for aluminum foil bag printing, the pH value should be controlled between 8.5 and 9.
③烘干温度应控制在五十、六十摄氏度之间,烘干时,风量要大,以保证转移到薄膜上的水性油墨可以风干。
③ The drying temperature should be controlled between 50 and 60 ℃. When drying, the air volume should be large to ensure that the water-based ink transferred to the film can be dried quickly.
④油墨倒入墨槽后,先把印版滚筒空转2min~3min后,再开始印刷,以保证印版滚筒湿润,有效搅拌油墨。在印刷的过程中,如遇到临时停机情况,要保证印版继续转动,防止印版上的油墨干固,而造成网穴堵塞。
④ After the ink is poured into the ink tank, the plate cylinder shall be idled for 2min-3min before printing, so as to ensure the plate cylinder is wet and effectively mix the ink. In the process of printing, in case of temporary shutdown, it is necessary to ensure that the plate continues to rotate to prevent the ink on the plate from drying and solidifying, resulting in blocking of mesh holes.

⑤印版滚筒的网穴深度更好浅一点,这样有利于加快印刷速度,节约油墨。网穴过深,不但阻碍印刷速度、耗费油墨,还容易发生粘连。具体深度保持在15~25um。
⑤ The screen hole depth of the plate cylinder is better to be shallow, which is conducive to speeding up the printing speed and saving ink. Too deep mesh hole not only hinders printing speed, consumes ink, but also easily causes adhesion. The specific depth is kept at 15-25um.
⑥定做食品铝箔袋印刷前,根据印版滚筒网穴的深度,调整油墨粘度,不要在印刷的过程中往油墨中加水,如有需要,可添加新油墨,保证音频色相始终一致。
⑥ Before the customized food aluminum foil bag printing, adjust the ink viscosity according to the depth of the screen hole of the plate cylinder. Do not add water to the ink during the printing process. If necessary, add new ink to ensure the consistent audio color.
⑦印刷完毕后,需立刻将印版滚筒洗净,早墨槽中倒入清水,同时转动印版滚筒进行清洗,或者加入3%的洗衣粉溶液,进行清洗。
⑦ After printing, the plate cylinder shall be cleaned immediately, and water shall be poured into the early ink tank. At the same time, the plate cylinder shall be rotated for cleaning, or 3% detergent solution shall be added for cleaning.
目前,已经将铝箔袋定做划入强制使用3C认证目录内,这意味着,水溶性铝箔袋印刷将获得更广阔的发展,由于其具有无苯、无刺激性气味、不污染食品,非常适合食品铝箔袋的印刷。在环保的大趋势下,这种环保油墨印刷的铝箔袋产品,将迎来极好的发展机遇。
At present, the country has put the custom-made aluminum foil bags into the 3C certification catalogue of compulsory use, which means that the water-soluble aluminum foil bag printing will get a broader development, because it has no benzene, no irritant smell, no pollution of food, it is very suitable for the printing of food aluminum foil bags. Under the general trend of environmental protection, this kind of environmental protection ink printed aluminum foil bag products will usher in excellent development opportunities.
