열 밀봉 응용 분야에 사용하기에 특히 적합한 프로필렌 삼원공중합체가 구성된다. 예를 들어, 상기 프로필렌 삼원공중합체는 다층 필름에 열 밀봉 층을 형성하는 데 사용될 수 있다. 상기 열 밀봉 층은 포장물 및 기타 물품을 형성하기 위해 2개의 대향 필름 층을 함께 결합시키는 데 사용될 수 있다. 상기 프로필렌 삼원공중합체는 증가된 무작위적인 에틸렌 분포를 갖도록 형성되어, 감소된 중합체 결정화도, 감소된 용융 온도, 및 더 낮은 열 밀봉 온도를 생성한다. A propylene terpolymer is constructed that is particularly well suited for use in heat seal applications. The propylene terpolymer, for instance, can be used to form a heat seal layer on a multilayer film. The heat seal layer can be used to bond two opposing layers of film together for forming packages and other articles. The propylene terpolymer is formed with an increased random ethylene distribution that results in reduced polymer crystallinity, reduced melting temperature, and lower heat seal temperature.
