배합된 중합체를 제조하기 위한 연속적 공정은, 천연 전분, 폴리올레핀, 및 상용화제를 혼합하는 단계; 그리고 압출기를 사용하여 위에서 얻어진 혼합물로부터 배합된 중합체를 형성하는 단계를 포함한다. 공정은, 또한, 압출기에서 천연 전분, 폴리올레핀, 및 상용화제를 혼합하는 단계를 포함할 수 있다. 폴리올레핀은 석유계 또는 생물 기반 폴리에틸렌일 수 있고, 상용화제는 말레산 무수물 그래프트된 폴리올레핀일 수 있다. 공정은, 글리세린 등의 가공 조제를 혼합하는 단계, 그리고 배합된 중합체를 필름으로 형성하는 단계를 더 포함할 수 있다. A continuous process for manufacturing a blended polymer includes mixing a native starch, a polyolefin, and a compatibilizer; and forming the blended polymer from the resulting mixture using an extruder. The process can also include mixing the native starch, the polyolefin, and the compatibilizer in the extruder. The polyolefin can be a petroleum- or bio-based polyethylene, and the compatibilizer can be a maleic anhydride grafted polyolefin. The process can further include mixing a processing aid such as glycerin, and forming the blended polymer into a film.
