摘要：

<p>A carton, case or tray formed utilizing a hot melt adhesive composition said adhesive consisting essentially of a) 10 to 60% by weight of at least one ethylene n-butyl acrylate copolymer containing 25 to 45% by weight n-butyl acrylate and having a melt index of at least about 850; b) 20 to 60% of a rosin ester tackifying resin; c) 10 to 50% by weight of a microcrystalline or paraffin wax having a melting point of 150 to 200 DEG F; d) 1 to 20% by weight of a polymeric additive selected from the group consisting of ethylene vinyl acetate containing 10 to 40% by weight vinyl acetate, ethylene methyl acrylate polymers containing 10 to 28% methyl acrylate, ethylene acrylic acid copolymers having an acid number of 25 to 150, polyethylene, polypropylene, poly-(butene-1-co-ethylene), and lower melt index ethylene n-butyl acrylate copolymers; and e) 0 to 1.5% stabilizer, said adhesive characterized by a viscosity of less than 3000 cps at 135 DEG C, fiber tearing bonds from within the range of -35 to 40 DEG C.</p>
