Kraft paper is widely used in packaging boxes, hand bags, paper bags and other applications due to its good logistics performance, flexibility and other characteristics. However, if the color of kraft paper is uneven, its quality and sales difficulty will become extremely difficult. So what should we do if the color of kraft paper is unstable?

According to the application requirements, take actual color comparison assessment: because the color of kraft paper will be different due to the influence of light source, light angle and human factors. At this time, it is necessary to dye according to the color of the actual kraft paper. If you want to have more red tones when printing and dyeing, then use a uniform color for color mixing and add red dye. This can effectively reduce color deviation.

When adding dye, use a metering pump to meter in: The traditional dye mixing system generally uses continuous mixing, and if the amount of dye is small, it will affect the uniformity of color matching. But if you use a metering pump to meter the dye. On the one hand, it can prevent different dyes from dissolving together to produce lakes that make the dyes uneven and waste dyes. On the other hand, it is convenient to adjust the amount of a certain dye separately.

Our factory is producing kraft paper dyes for more than 26 years. For details about paper dyeing technology, welcome contact with us.
