<P>PROBLEM TO BE SOLVED: To provide a plastic film for food packaging and for the medical container such as the bag for transfusion and drug solution, etc., the plastic film that is superior in the carbon neutral property and the safety and health property, and is superior in the high speed bag forming processing, the impact resistance, the blocking resistance, the flexibility, and the transparency, etc. <P>SOLUTION: The plastic film is formed by the co-extrusion method and comprises at least three layers including: a first layer 1 whose principal ingredient is polyamide obtained by condensation polymerization of monomer that is at least partially the natural origin raw material; a second layer 2 whose principal ingredient is the graft copolymer of the mixture of the linear low density polyethylene comprising the copolymer of the ethylene taken out from the bioethanol obtained by fermentation of the plant origin raw material and the αolefin of carbon number 3-20 and the high-density polyethylene comprising the simple polymerization of the ethylene, and anhydride monomer of unsaturated carboxylic acid or unsaturated dicarboxylic acid; and a seal layer 3 whose principal ingredient is the mixture of the linear low density polyethylene and the high density polyethylene. <P>COPYRIGHT: (C)2013,JPO&INPIT |
