Abstract

See full text

The present invention relates to a hot melt film containing a biomass-based thermoplastic polyurethane resin, and is not only environmentally friendly to the human body as it contains a biomass-based thermoplastic polyurethane resin prepared by reacting a biomass-derived polyol with a diol-based chain extender and diisocyanate in a range of 20-70% by weight, accordingly, by containing hydrophobic nano-silica, it is possible to secure properties such as excellent high heat resistance, elasticity, uniform adhesion strength, and excellent durability at the petroleum-based level, and also provides a hot melt film containing a biomass-based thermoplastic polyurethane resin that can prevent overflow during the bonding process and improve the weight and texture of the product.
