<p>The present invention relates to a new laminated film to package a retort food. The laminated film to package a retrot food includes: a polypropylene base resin layer; and a composite composition layer formed on a surface of the polypropylene base resin. The composite composition layer includes: a norbornene based ring shaped polyolefin of 5-40 parts by weight, a polyolefin base rubber or a polyolefin elastomer of 0.5-20 parts by weight, and a nanoinorganic particle of 1-20 parts by weight based on a polypropylene resin of 100 parts by weight. According to the present invention, the laminated film to package a retrot food may represent excellent heat-resistant properties, transparency, and water barrier properties to satisfy a recent strict retrot processing condition.</p> |
