According to the introduction of water activated kraft paper tape manufacturer, opacity refers to the nature of paper opacity. The opacity of paper depends on the paper. The amount of light scattering ability within the paper is at the interface (i.e. the number of independent particles inside) and the difference between the light scattering capacity and the refraction scattering at the interface.
The multiple light scattering interfaces have larger difference between refraction and scattering at the interface, greater light scattering ability of paper and higher opacity.

Paper products are mainly used as means of production, more than half of which are used as printing materials, so most of the paper must be able to provide opacity.
The opacity of paper is essentially the result of the dispersion of light due to the "optical uniformity" structure of the paper. The formation mechanism of paper opacity includes reflection, refraction, diffraction and absorption.
There are many factors that affect the opacity of paper, mainly fiber adhesion.
In addition, the nature and amount of pigment, the use of retention aid, the ratio of paper, the line pressure of paper calendering will also affect the opacity.
Each index of paper restricts each other. The process of papermaking is to maximize the performance of all raw materials and make the indexes reach the maximum balance.
