Usually, we all know that self-adhesive label, also known as self-adhesive label, timely paste, instant paste, etc., is a composite material of paper, film or special materials for fabric, coated with adhesive on the back, coated with silicon paper for protection, and after printing, die-cutting processing to become the finished product label. There are many kinds of self-adhesive labels and they are used in different fields.

Before using the self-adhesive label, it is important to test the type of adhesive, to see whether this adhesive belongs to the self-adhesive hot sol or glue paper. Some adhesives react with certain substances, so when we know the specific substances with which they react, we have to learn how to avoid them. There are a variety of adhesive label viscosity test methods, which to choose depends on everyone's preferences, the following Zhitong Xiaobian to organize a few test methods on adhesive label viscosity, you just need to choose any one of them to test.

1. Initial adhesion: Common is the rolling ball method, that is, on an inclined surface will be fixed with the adhesive surface up, and then let the standard steel ball (there are points of size) slide down from the above, the bigger the steel ball can be stuck to, the greater the initial adhesion.

2. Holding adhesive force: that is, glue two standard steel plates with hooks together, and then hang one steel plate on the fixed frame, and put 2kg weight on the other end. See how long the steel plate below will not fall down, and calculate the duration.

3. Peeling force: the adhesive is glued to the standard steel plate, the label is torn off with the constant speed of the instrument, and the force used by the instrument is the peeling force of the adhesive.
