Foam composite structure comprising a blend of polypropylene and homogeneous ethylene/alpha-olefin copolymer

摘要

A foam sheet including a blend of polypropylene and homogeneous ethylene/alpha-olefin copolymer, wherein the polypropylene is present in the blend at a weight percentage ranging from 70 to 95 and the homogeneous ethylene/alpha-olefin copolymer is present in the blend at a weight percentage ranging from 5 to 30. Foam composite structures in which the aforedescribed foam sheet is bonded to polyethylene and/or polypropylene foam sheets are also disclosed.
