ABSTRACT:
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.
