Repulpable Pressure Sensitive Adhesives Designed for Paper Recycling, 1993 Recycling Symposium Proceedings
C. S. Chou
Conventional pressure sensitive adhesives are known to introduce "stickies" which disrupt the repulping and paper-making process. Conventional pressure sensitive adhesives are also known as a major source of contamination in office wastepaper recycling. This paper discusses the development of pressure sensitive adhesives which can be repulped with conventional pulping technologies; yet the adhesives which can be repulped with conventional pulping technologies; yet the adhesives maintain the appropriate balance of properties, such as peel, shear, and tack, for different end use applications. A test method which would simulate the actual pulping process is introduced. Factors which would affect the degree of repulpability are also discussed.
