How to determine if it is a truly good packaging paper?

As long as you master these points, choosing high-quality packaging paper is actually very simple,

1.Firstly, check whether its appearance is smooth, delicate, and has uniform transparency ( uniformity);

2.The second check is its physical strength performance. Pull it by hand to check if the tensile force in both vertical and horizontal directions is high. 

Good packaging paper has high tensile force in both directions;

3.

3.The third test is its tearing strength. Tear the paper along the longitudinal direction to see the gap. If the force is large and the tear is uneven, it indicates a high tearing strength. The one with a high average in both vertical and horizontal directions is considered a top grade;

4.The fourth test is the transparency of the paper. Cover the packaging paper with a newspaper printed in bold font number one, one by one, until the outline of the bold font cannot be clearly seen by adding another. 

Count the number of layers it covers, and the more layers it can cover the packaging paper, the better. 

This indicates that the transparency of the copy paper is higher, indicating that its quality is higher.

Usually excellent copy paper, taking 17q/m2 copy paper as an example, can cover up to 6-8 layers, with extremely excellent ones reaching 12 layers.
