    • This invention is directed to a method for cold sealing a plurality of substrates, typically plastics, foil, paper or combinations thereof, utilizing a cold-sealable adhesive composition that is free of natural latexes ("natural latex-free"). The present invention is also directed to a natural latex-free, cold-sealable adhesive composition that as used therein comprising a latex polychloroprene in the range between about 40% to 100% by weight and a tackifier resin dispersion in the range of about 60% to 0% by weight. In another embodiment, the present invention is directed to a sealed package, wherein the package is sealed in accordance with the method and/or composition of the present invention. A cold seal adhesive composition of the present invention is particularly suitable for use in high-speed printing press and preferably by means of the forward gravure method.

    • Disclosed are compositions which include an ethylene polymer derived from at least one polar monomer with one or more ester groups, which polymerize with ethylene, (e.g., a copolymer, or low molecular weight copolymer having a relatively high melt index, derived from ethylene and vinyl acetate and/or a copolymer, or low molecular weight copolymer having a relatively high melt index, derived from ethylene and «-buty! acrylate) and a rosin ester, The rosin ester can have a low hydroxy! number (e.g., a hydroxy! number six or five or less), a low acid number (e.g., an acid number of ten or less), a relatively low PAN number (e.g., a PAN number less than twenty-two or in between eight and twenty), a relatively high third moment or third power average molecular weight (Mz), (e.g., an Mz value in between 2500 and 12000 g/mol), a low sulfur content (e.g., a sulfur content lower than 600 ppm prior to antioxidant addition) or combinations thereof. The compositions can exhibit a high heat stress resistance (e.g., a heat stress pass temperature value higher than 52 °C or in between 48 °C and 60 °C) and/or improved viscosity stability and/or color stability upon thermal aging and/or improved compatibility.
