<p>The present invention relates to a polyolefin-based multifunctional food packing material having a multi-layered structure. The food packing material may include: a polypropylene rein layer; an organic/inorganic hybrid-based gas blocking layer; an adhesive layer; and a composite resin film layer which is formed by adding a polyolefin-based thermoplastic elastomer, nanoinorganic particles, or a mixture thereof into polyolefin. According to the present invention, the novel polyolefin-based multifunctional food packing material having a multi-layered structure has proper mechanical properties, high transparency, high oxygen blocking and waterproof properties, heat resistance, and impact resistance. At the same time, the food packing material can be provided as a packing material for retort food and sterilized rice which is not needed to be buried in the ground or incinerated, and can be reused.</p> |
