▎ 摘  要

NOVELTY - Eco-friendly laminated film capable of post-sterilization comprises a film layer (100) comprising of polybutylene adipate terephthalate (PBAT), polybutylene succinate (PBS), polyhydroxyalkanoate (PHA), polylactic acid (PLA), thermoplastic starch (TPS), polyvinyl alcohol (PVA), polycaprolactam (PCL), polyethylene (PE), polypropylene (PP), Oxo- polyethylene (PE), Oxo-polypropylene (PP), Bio-polyethylene, Bio-polypropylene, Bio-polyethylene terephthalate (PET), ethylene vinylacetate (EVA), ethylene vinyl alcohol (EVOH), polyvinylidene chloride (PVDC), polyethylene terephthalate (PET), polyhydroxy aldehyde and Nylon(RTM: Synthetic polyamide polymer), and a paper layer (200) formed on the film layer and containing cotton pulp and/or wood pulp. USE - The laminated film is useful in eco-friendly packaging material. ADVANTAGE - The laminated film can provide a high-quality, eco-friendly laminated film in which quality is not damaged when the contents are packaged and subjected to a sterilization process, does not damage the printing on the film and the quality of the film packaging material itself even if it goes through a sterilization process (e.g., retort, boiling). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an eco-friendly packaging material formed by sealing a laminated film in which at least two layers are laminated with a strength of ≥ 1 kgf/15 mm, where the eco-friendly packaging material is a pump, a spout, a zipper, a polymer film having a thickness of ≤ 10 mm, and a tear tab. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of an eco-friendly laminated film. 100Film layer 200Paper layer
