What are the factors that influence the release force of adhesive materials?

The release force of a sticker material refers to the force required when the backing paper is separated from the adhesive surface of the paper.

What is the measurement method for the release force of adhesive materials?

The method of detecting the release force is similar to the peel strength and is performed on a special testing machine. The specific method is to put a standard size sample face material down in a standard temperature and humidity environment and fix it on the test platform with double-sided adhesive tape; peel off one end of the bottom paper and fix it on the test head, then the test head is vertical At the sample (90 degrees ) , the backing paper is lifted upwards with a certain speed and pulling force. The data displayed on the testing machine at this time is the release force.

What are the factors that influence the release force of adhesive materials?

The release force is an important indicator of the adhesive material, and its size directly affects the printing process and application of the label. The size of the release force is affected by five factors: coating technology. The advanced coating equipment and processes directly affect the amount of silicon coating and uniformity; silicone oil conditions. Silicon oil quality, composition, drying principle; raw paper condition. The surface smoothness, density uniformity and thickness of the base paper have an influence on the silicon coating; the coating amount. The amount of silicone oil coating is proportional to the release force; adhesive. The adhesive force of the adhesive is proportional to the release force.
