Hot-melt pressure sensitive adhesive packaging, preform, and method

摘要

The present invention is directed to a method for the waste-free packaging for a hot-melt pressure sensitive adhesive that comprises extruding a hot-melt pressure sensitive adhesive into a continuous tubular film, wherein the film is compatible with being integrated into the composition of the hot-melt adhesive composition; and crimping the continuous tubular film at a predetermined distance such that a predetermined amount of the hot-melt pressure sensitive adhesive is isolated between at least two of the crimps to produce a compatibly packaged hot-melt adhesive composition. By melting the compatibly packaged hot-melt adhesive composition in a glue pot, the compatible packaging becomes compatibly integrated into the molten hot-melt adhesive composition.
