▎ 摘  要

NOVELTY - Environmentally-friendly laminated film comprises a film layer made of polybutylene adipate terephthalate (PBAT), polybutylene succinate (PBS), olyhydroxy aldehyde (PHA), polylactic acid (PLA), thermoplastic starch (TPS), polyvinyl alcohol (PVA), polycaprolactam (PCL), polyethylene (PE), polypropylene (PP), oxo-PE, oxo-PP, bio-PE, bio-PP, bio-PET, ethylene vinyl acetate (EVA), ethylene vinyl alcohol (EVOH), polyvinylidene chloride (PVDC), polyethylene terephthalate (PET) and nylon, a paper layer (200) formed on the film layer (100) and a coating layer (300) formed on the paper layer. USE - The laminated film is useful in environmentally friendly packaging material (claimed). ADVANTAGE - The laminated film: provides high-quality environmentally packaging material that does not damage the printing of the packaging material and the quality of the packaging paper even in a cryogenic frozen state. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for environmentally-friendly packaging material comprising the environmentally-friendly laminated film, where the environmentally-friendly packaging material is sealed by pump, spout, zipper, polymer film with thickness of ≤ 10 mm, and/or a tear tab which has sealing strength of 1 kgf/15mm. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the laminated film. 100Film layer 200Paper layer 300Coating layer
