摘要： A method and apparatus for post mixing an additive with a hot melt adhesives. The method includes the steps of providing a source of molten hot melt adhesive, feeding the hot melt adhesive to an inlet of a mixer, simultaneously feeding an additive for the hot melt adhesive to the inlet of the mixer, mixing the additive and molten hot melt adhesive in the mixer to form a homogeneous mixture, and recovering the homogenous mixture. The additive is preferably selected from wetness indicators, antimicrobial agents, pigments, dyes, ultraviolet light absorbers, antioxidants, fluorescent agents, pH indicators and fragrances. The method may be practiced either on a batch basis, or on a continuous basis. The apparatus includes a vessel containing molten hot melt adhesive, a mixer located downstream from the vessel, the mixer having an inlet and an outlet, a first pump located between the vessel and the mixer for pumping molten hot melt adhesive from the vessel to the inlet of the mixer, a source of an additive for the hot melt adhesive, and a second pump located between the source of the additive and the mixer for pumping the additive to the inlet of the mixer. The mixer may comprise either a static mixer or a dynamic mixer.

摘要： A method for packaging plastic material using a film to surround the material, and more particularly to a method for packaging hot melt adhesives, the resulting package formed thereby, and the film composition used therein. The method is preferably a coextrusion process for packaging a pressure sensitive hot melt adhesive by extruding a hot melt adhesive through a die orifice, and coextruding a wax-based polymeric film to surround the hot melt adhesive. The coated adhesive may then be formed into individual packaged units having a finite size and shape. The polymeric film comprises a composition having at least 25% by weight of a wax material, an enthalpy of fusion of at least about 100 J/g, and an elongation value at break of at least about 100%. Any type of hot melt adhesive formulation can be packaged or surrounded by the polymeric film in the process. Also, the specific enthalpy of fusion desired and/or elongation value at break desired for the polymeric film can be obtained by blending an appropriate amount of partially crystalline ethylene-based polymer together with a thermoplastic elastomeric block copolymer and/or an ethylene based or propylene-based elastomer.
