HYDROPHOBIC NANO-SILICA-BLENDED THERMOPLASTIC HOT-MELT FILM HAVING EXCELLENT ADHESIVE STRENGTH

摘要

The present invention relates to a hydrophobic nano-silica-blended thermoplastic hot-melt film having excellent adhesive strength. Specifically, the thermoplastic hot-melt film comprises hydrophobic functional group-bearing nano-silica in an amount range of 0.1-5 phr (parts per hundred resin) and has a thickness of 0.02-0.3 mm, wherein the nano-silica has a particle size of 1-100 nm.
