MOLDED BODY OF LAMINATED PLASTIC DERIVED FROM BIOMASS, AND MANUFACTURING METHOD THEREFOR

摘要

Provided are: a high-impact molded body of laminated plastic derived from biomass, such that when the molded body takes the form of a hermetically sealed bottle, the bottle does not deform under a load; and a manufacturing method thereof. The molded body of laminated plastic derived from biomass is blow-molded and is characterized in that: at least 25% by weight of at least one layer consists of biomass-derived plastic; the other layers are polyolefin resin; and, after molding, an annealing process is performed wherein the temperature is increased from room temperature by 5 to 20°C per minute, maintained at 85 to 100°C for 3 to 10 minutes, and then gradually decreased by 10 to 15°C per minute.
