Abstract
Blown film process is a major industrial process for the manufacture of aliphatic polyester films. Despite of its importance, relatively little has been reported on the processing characteristics and the structure development of aliphatic polyesters in blown film process. In this work, therefore, processing-structure-property relationship of aliphatic polyester blown films was evaluated. Mechanical properties of blown films prepared under various process conditions were measured. Film structure was analyzed by using FTIR with attenuated total reflection (ATR) mode. The biodegradation behavior of blown films was examined through soil burial test. Some information was also provided to establish a general understanding for the material design of biodegradable mulching films.

블로운 필름 공정온 지방족 폴리에스테르 필름을 제조하는데 있어 중요한 생산 공정이다. 이러한 중요성에도 불구하고 지방족 폴리에스테르 수지에 대한 블로운 필름 공정 특성이나 공정 조건에 따른 블로운 필름의 구조 변화에 대한 연구는 매우 미진한 형편이다. 본 연구에서는 여러 가지 공정 조건하에서 제조된 블로운 필름의 기계적 물성을 측정하고, IR-ATR dichroism 방법으로 구조를 분석하며, 토양매립시험을 통하여 생분해 속도를 조사함으로써 지방족 폴리에스테르 블로운 필름의 가공-구조-물성 (기계적 강도/생분해성) 상관관계를 평가하였다. 또한 지방족 폴리에스테르를 농업용 멀칭필름으로 사용할 수 있는지 검토하였다.
