Zusammenfassung:	The present invention provides: a recycled chip which has intrinsic viscosity and a DEG unit content within specific ranges and realizes remarkable film-forming properties; and a recycled PET film manufactured therefrom and not only having excellent breaking strength and elongation at break, but also having a significantly low heat shrinkage rate, to solve the low breaking strength and elongation at break and high heat shrinkage rate of conventional recycled PET films. La présente invention concerne : un copeau recyclé qui présente une viscosité intrinsèque et une teneur en motifs DEG dans des plages spécifiques et qui réalise de remarquables propriétés filmogènes ; et un film de PET recyclé fabriqué à partir de celui-ci et présentant non seulement une excellente résistance à la rupture et un excellent allongement à la rupture, mais également un taux de retrait thermique significativement faible, pour résoudre la faible résistance à la rupture et le faible allongement à la rupture et le taux de retrait thermique élevé de films PET recyclés classiques. 본 발명에 따른, 재생 PET 필름은 종래의 재생 PET 필름이 가진 낮은 파단강도 및 파단신율과 높은 열수축률 해결하고자, 특정 범위의 극한점도 및 DEG 단위함량을 가진 현저한 필름제막성을 구현하는 재생칩 및 이로부터 제조된 우수한 파단강도 및 파단신율를 가질 수 있을 뿐 아니라, 현저히 낮은 열수축률을 가진 재생 PET 필름을 제공하는 것이다.
