一、塑料包装印刷材料中的静电形成与积累静电是自然界中的常见电运动现象。电运动是物质的一种基本运动形式,它具有无处不在的性质。只不过方式不同而已。例如,静电感应现象等。静电给印刷纸张和塑料带来一系列难题。纸张印刷可以通过静电消除器来消除静电,但这种方法应用到塑料包装印刷上效果甚微。因为塑料包装印刷中用量最多的是聚乙烯(PE)和聚丙烯(PP)。例如:PE分子结构式为 First, the plastic packaging materials in the formation and accumulation of static electricity static electricity is a common phenomenon in nature. Electric movement is a basic form of movement of matter that has ubiquitous properties. Only different ways. For example, electrostatic induction phenomenon. Electrostatics poses a series of problems for printed paper and plastic. Paper printing can be static eliminator to eliminate static electricity, but this method applied to plastic packaging printing with little effect. Because the most used plastic packaging printing is polyethylene (PE) and polypropylene (PP). For example: PE molecular structure is
