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

A method for the waste-free packaging of a hot-melt pressure sensitive adhesive composition comprising the steps of:

• a. providing a preform for hot-melt adhesive composition comprising a continuous sheet of heat sealable film having two opposing longitudinal edges, namely, a first edge and an opposing edge, that are capable of forming a heat seal with one another, said continuous sheet of heat sealable film having a composition that is compatible with being integrated into the composition of said hot-melt adhesive composition;
• b. heat sealing the area along the first edge of the preform to an area along the opposite edge of the preform to form a continuous tubular film capable of receiving an extruded hot-melt pressure sensitive adhesive therein;
• and
• c. extruding a hot-melt pressure sensitive adhesive into said continuous tubular film at a predetermined rate;
• d. crimping said 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;
• and
• e. melting said compatibly packaged hot-melt adhesive composition in a glue pot whereby said compatible packaging becomes compatibly integrated into said molten hot-melt adhesive composition.
