摘要：
The easy-to-tear stretched aliphatic polyester film of the present invention is characterized in that the edge tear strength in the longitudinal direction and the transverse direction is not more than 22 N. The easy-to-tear stretched aliphatic polyester film of the present invention is produced by a method of irradiation of actinic rays on an aliphatic polyester film or a method of film-forming a film obtained by laminating aliphatic polyesters having different melting points in three layers of A/B/A under particular film-forming conditions.
