Combination of elastomeric film composition and adhesive for a stretch laminate |
摘要 |
A structure comprising an elastic film layer and an adhesive in contact therewith is disclosed. The elastomeric film layer may include a plasticizer and greater than 7 percent by weight of a tackifier. The elastomeric film formulation provides reduced loss of adhesion strength with the adhesive over time, providing for improvement in mechanical performance of the stretch laminate over time. |

1. A structure including an elastomeric film layer and an adhesive in contact therewith, wherein the elastomeric film layer comprises:
from 53 to 65 percent by weight of a stvrene-ethylene-ethyene-propylene-styrene elastomeric block copolymer having a rubbery midblock of a hydrogenated copolymer of isoprene and butadiene; from 8 to 15 percent by weight of a thermoplastic polymer additive; from 10 to 20 percent by weight of a tackifier; and from 10 to 20 percent by weight of a plasticizer;and wherein the adhesive comprises:
at least one homogeneous polyolefin copolymer of ethylene with propylene or alpha olefins; up to 60 percent by weight of a tackifier; and up to 15 percent by weight of a plasticizer. |
