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決問題，紙塑復合袋滲色的原因：

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印刷版面邊緣滲有顏色。

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

②采用的油墨搭配不當。

② The ink used is not matched properly.

③使用的稀料過多，尤其是稀料與油墨互溶性差。

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

解決方法如下：

The solution is as follows:

1、用加溫清洗油墨。開始用加溫方式來處理表面油墨和油污問題，取得一定成效，清洗出來的料白凈，品質持久度較高，一段時間內成為大多數企業方法。但使用鍋爐加溫具有一定的危險性，且燃料成本較高。

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、使用紙塑復合袋油墨清洗劑。使用方法簡單，生產時無需加熱，只需將廢舊蛇皮袋浸入清洗中5-8分鐘，再用破碎清洗設備洗滌3-5分鐘，再用清水漂洗一遍即可或根據生產工藝而定。

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.
