Because of its convenience, easy tape has been widely used in the field of sanitary products. With the continuous progress of modern society and the continuous improvement of people's living standards, as one of the raw materials of health products, easy tape has been continuously developed to meet people's growing new demand for high-quality and functional health products. Today, let's take a look at re-seal tape.
The substrate of easy tape generally adopts polypropylene film. One side of the film is coated with hot-melt pressure-sensitive adhesive, and the other side is coated with anti adhesion agent. It needs to be produced in a clean environment. The viscosity of the adhesive should be moderate, not too sticky, as long as it can be bonded with the plastic film. Due to the polypropylene film with a thickness of 0.09mmm-0.12mm, it will be completely bonded with the plastic packaging film after being coated with adhesive, so it is difficult to tear off the tape from the film, that is, it is difficult to unseal. When the base material is coated with glue, the method of strip coating is used to leave a blank edge on one side of the tape without glue, which can solve the problem that consumers tear open the sealing of the packaging film when using.
With the rapid development of relevant production lines in the field of sanitary products, the speed of the production line has reached thousands of pieces per minute. Therefore, the quality requirements for easy tape are becoming higher and higher. However, due to the thickness deviation of polypropylene film in the production process, and the blank edge on one side left during gluing, the thickness of the two end faces of the tape is uneven, that is, the tightness on both sides of the tape is inconsistent, and one side is often uneven, forming the phenomenon of "lotus leaf edge". The product appearance quality is affected, which is not convenient for assembly line production. The speed of assembly line equipment slows down and the output is reduced. This is a problem that must be solved for the further development of this raw material.
With the continuous progress of modern society, the continuous improvement of people's living standards, and the continuous development of large-scale production technology came into being. Its birth and rapid development have changed people's lives and affected the process of human civilization. As one of the raw materials of sanitary products, easy tape has been widely used in daily life. Understanding re-seal tape is conducive to its better development.
