Pressure-sensitive adhesive tapes were mass-produced in my country in the early 1980s. Water-emulsion acrylate pressure-sensitive adhesives were widely used in the production of BOPP packaging tapes. There are more than ten sets of cross-linking systems in the country with a scale of 0.5-15,000 T/year. Emulsion-type acrylate pressure-sensitive adhesive tape is the most productive and widely used variety of pressure-sensitive adhesive tapes. It has the incomparable advantages of traditional solvent-based pressure-sensitive adhesives: Good viscosity, safe use and good aging resistance. Its biggest use is in the production of BOPP pressure-sensitive adhesive tape, which is made of biaxially oriented polypropylene film (BOPP) and coated with acrylate pressure-sensitive adhesive. BOPP tapes can be used on light or heavy packaging depending on the thickness of the product. It is the fastest-growing polymer emulsion adhesive tape in my country since the 1980s. Emulsion-type acrylate BOPP pressure-sensitive adhesive tape has been developed rapidly for nearly two or three decades, and its manufacturing technology and application technology are relatively mature. It is widely used in coating tapes, trademarks, security signs, double-sided tapes and Various decorative materials and other pressure-sensitive products. In recent years, through various methods of improvement, the performance of emulsion type acrylate BOPP pressure-sensitive adhesive tape has been improved, and the application field has become wider.

As the world pays more and more attention to environmental protection issues, the development of solvent-based pressure-sensitive adhesives is limited, while the less polluting emulsion-based pressure-sensitive adhesives have received much attention. In recent years, countries have been vigorously developing emulsion-type acrylate pressure-sensitive adhesives. According to statistics, among all kinds of pressure-sensitive adhesives produced in my country, emulsion-type acrylate pressure-sensitive adhesives have accounted for about 65%. In the United States and Europe, emulsion-type acrylate pressure-sensitive adhesives occupy a large proportion in hygiene, labeling, sealing tapes, etc., and emulsion-type acrylate BOPP pressure-sensitive adhesive tapes occupy a considerable proportion in packaging sealing tapes. proportion of. However, this type of adhesive tape also has shortcomings such as poor water resistance, poor high temperature and high humidity resistance, and coating drying. Therefore, it is of great practical value to study the performance testing method of this type of pressure-sensitive adhesive tape. So far, no scholars have published relevant articles on the performance changes of this type of pressure-sensitive adhesive tape under different working conditions.
