In today's packaging design, in order to pursue more amazing and realistic printing effects, the printing colors of paper plastic composite bags are often rich and diverse, but at the same time, there will be color seepage during production. How to solve this problem? Let's take a look at the answer given by our packaging bag manufacturer.

先了解原因才能更好的解决问题，纸塑复合袋渗色的原因：

Only by understanding the reasons can we better solve the problem. The reasons for the color seepage of paper plastic composite bags are as follows:

①印刷版面边缘渗有颜色。

① The edge of the printing plate is permeated with color.

②采用的油墨搭配不当。

② The ink used is not matched properly.

③使用的稀料过多，尤其是稀料与油墨互溶性差。

③ Too much thinner is used, especially the miscibility between thinner and ink.

解决方法如下：

The solution is as follows:

1、用加温清洗油墨。开始用加温方式来处理表面油墨和油污问题，取得一定成效，清洗出来的料白净，品质持久度较高，一段时间内成为大多数企业方法。但使用锅炉加温具有一定的危险性，且燃料成本较高。

1. Wash the ink with heating. We began to use heating method to deal with the problem of surface ink and oil pollution, and achieved certain results. The cleaned materials are white and have high quality durability, which has become the method of most enterprises for a period of time. However, the use of boiler heating is dangerous and the fuel cost is high.

2、使用纸塑复合袋油墨清洗剂。使用方法简单，生产时无需加热，只需将废旧蛇皮袋浸入清洗中5-8分钟，再用破碎清洗设备洗涤3-5分钟，再用清水漂洗一遍即可或根据生产工艺而定。

2. Use paper plastic composite bag ink cleaner. The use method is simple. There is no need to heat during production. Just immerse the waste snake skin bag in the cleaning for 5-8 minutes, wash it with crushing and cleaning equipment for 3-5 minutes, and rinse it with clean water, or it can be determined according to the production process.
