摘要: The invention provides stretch film laminant adhesives, methods of using the adhesives to bond substrates together, and to articles of manufacture comprising the adhesives. It has been discovered that a stretch film lamination adhesive, which comprises a metallocene catalyzed polyolefin copolymer with a density greater or equal to 0.870 g/cm3 and a peak melting point greater than 100° C., a plasticizer having a number average molecular weight greater than 1,000 g/mol, and a tackifier with a softening point greater than 110° C., has high creep resistance and low plasticizer migration and bleed-through making them particularly well suited for disposable personal care garments.
