Abstract
A container sealing composition made from a plastisol having a mass of hollow discrete microspheres incorporated therein. The composition is characterized by having increased shelf life, as manifested in reduced separation of the hollow discrete microspheres from the plastisol, and improved viscosity stability. The container sealing composition also exhibits uniform void volume which is essential for good sealability and seal quality.
