How to judge the quality of self-adhesive label coated paper

Judging the quality of self-adhesive label coated paper can be carried out from the following aspects:

Material check:

Observe the thickness and uniformity of coated paper. In general, the thickness of coated paper should be about 80g, and the material should be uniform without impurities.

Check the water resistance, temperature resistance and wear resistance of coated paper to ensure that it meets the requirements of the specific application environment.

Viscosity test:

Evaluate whether the label is sticky enough to stick firmly to the required surface.

Check the moderate degree of adhesion to avoid residue or damage to the surface of the attached material when it needs to be removed.

Print quality assessment:

Carefully observe whether the text, graphics and colors on the label are clear and accurate, and whether the colors are bright and have no obvious color difference.

Check the printing for defects, such as blurring, ghosting, or missing prints.

Size and shape check:

Verify that the size and shape of the label meet the design requirements, including length, width and shape regularity.

Check whether the cutting is neat and there is no burring or breakage.

Surface treatment observation:

Check whether the label surface is properly treated, such as smooth, matte, or coated, to meet appearance or protection needs.

Pay attention to check the uniformity and integrity of the coating to ensure the durability of the label.

Wear resistance test:

Wear resistance tests are carried out on the label to verify that it is prone to wear or fall off under a certain degree of friction.

This can be tested by simulating friction and scratching in a real-world use environment.

Suitability assessment:

The label is actually applied to the product or scene to observe its use effect and durability.

The actual application verifies that the label meets specific requirements, such as water, oil or tear resistance.

In summary, through the careful inspection and evaluation of the above seven aspects, the quality of self-adhesive label coated paper can be effectively judged. These steps help to ensure that the selected labels are of reliable quality, thereby improving the overall quality of the product and the user experience.
