a method of packaging thermoplastic hot melt adhesive compositions in a continuous process . the process is especially suited for hot melt pressure sensitive adhesives to provide convenient handling of such . the process includes the steps of : dispensing a thermoplastic composition into a hollow sleeve of thermoplastic film , wherein said film is submerged in a heat sink bath ; sealing the molten thermoplastic composition filled composition ; allowing the molten thermoplastic composition to cool and solidify while submerged in the heat sink bath . an apparatus for practicing the process includes : a means for providing a hollow sleeve of thermoplastic film ; a dispensing means for filling said hollow sleeve of thermoplastic film with a thermoplastic composition ; a heat sink bath adjacent to said dispensing means such that the hollow sleeve of thermoplastic film is submerged in said heat sink bath while being filled ; and a means for conveying the filled sleeve of thermoplastic film beneath the surface of the heat sink bath until said filled sleeve has substantially solidified .
