Composite film and manufacturing method thereof |
| abstract |
An ultra-thin film layer having a thickness of 100 nm or less made of a biopolymer while being laminated with a water-soluble polymer layer is provided by coextrusion with uniform quality and excellent productivity. A composite film in which a plurality of layers A having a thickness of 5 to 100 nm made of a thermoplastic biodegradable polymer and a layer B made of a thermoplastic water-soluble polymer are laminated. A composite film formed by coextrusion molding, wherein the ratio of the B layer is in the range of 25 to 75% when the cross section along the thickness direction is seen, and the total thickness of the composite film is 3 μm or more. . [Selection figure] None |
