Pressure-sensitive adhesive tape testing
[Project Introduction]
Pressure-sensitive adhesive tape is composed of pressure-sensitive adhesive, base material, primer, back treatment agent, etc. Pressure-sensitive adhesive is the most important component of pressure-sensitive adhesive tape. Its function is to endow the tape with pressure-sensitive adhesion properties. The main base materials used include fabrics, plastic films, paper, etc. The primer is used to increase the bonding strength between the pressure-sensitive adhesive and the base material. It is now widely used in packaging, electrical insulation, medical and health care, labeling and marking, etc. Adhesive tape has a wide range of applications in packaging. It has strong adhesion, is not easy to crack and has high tensile strength, which makes adhesive tape widely used. Among the various properties of pressure-sensitive adhesive tapes, undoubtedly its adhesiveness is the most important and can be expressed in multiple ways.
