Biodegradable poly(lactic acid) (PLA)/poly(butylene adipate‐co‐terephthalate) (PBAT) blends and films were prepared using melt blending and blowing films technique in the presence of chain extender‐Joncryl ADR 4370F. The ADR contains epoxy functional groups and used as a compatibilizer. The morphological, mechanical, rheological, thermal, and crystalline properties of the PLA/PBAT/ADR blown films were studied. Scanning electron microscopy micrographs of the films revealed more ductile deformation with increasing PBAT content. The addition of PBAT enhanced the toughness of the PLA film. Tensile tests indicated that the elongation at break increased from 20.5% to 334.6% in the machine direction and from 7.1% to 715.9% in the transverse direction. The Young modulus increased from 2690.5 to 395.6 MPa in the machine direction and from 2623.5 to 154.0 MPa in the transverse direction. The sealing strength of 40/60/0.15 PLA/PBAT/ADR film was the highest among all the samples up to 9.4 N 15 mm−1. These findings gave important implications for designing and manufacturing polymer packaging materials.

“…T cc is shifted to the lower temperature due to increase in molecular weight of PLA and PBAT when the BIBP existed. In addition, the chain mobility of the polymer segments would decrease during heating trace, so the cold crystallization temperature decreased . The decreased of T cc could promote the crystallization of PLA.…”

Blown films of poly(lactic acid) (PLA)/poly(butylene adipate‐co‐terephthalate) (PBAT) blends were prepared, bis(tert‐butyl dioxy isopropyl) benzene (BIBP) as crosslinking agent. From wide‐angle X‐ray diffraction results, PLA/PBAT/BIBP involved all the diffraction peaks were consistent with PLA and PBAT. For the DSC curves of PLA/PBAT/BIBP films, there were two glass transition temperature and two melt temperature, there existed two step decomposition in the thermogravimetric curves. Both Han plots and Cole–Cole plots indicated high homogeneity of the 40/60/0.1 PLA/PBAT/BIBP blend. SEM micrographs of the films revealed more ductile deformation with increasing PBAT content and 40/60/0.1 sample had better miscible compared with others. For the PLA/PBAT/BIBP films, tensile tests indicated that the elongation at break were increased with increasing PBAT content and the values of the tensile strength in the machine direction were higher than those in the transverse direction. The addition of PBAT, enhanced the toughness of the PLA/PBAT/BIBP films. From tear test and heat sealing test, the 40/60/0.1 PLA/PBAT/BIBP film exhibited the highest tear strength and the highest sealing strength among all the samples. POLYM. ENG.

“…For the PLA/PBAT/EuTT film, the tear strength was always lower along the MD relative to the TD. This difference can be attributed to the varying degrees of orientation of the lamellae within the plane of the films . The molecular chains of PLA/PBAT/EuTT blends could be arranged parallel along with the machine direction during the blowing films.…”

Rare earth europium(III) complex with α‐thenoyltrifluoroacetone and triphenylphosphine oxide (Eu (TTA)3(TPPO)2, shortened as EuTT) was synthesized in this paper, then blended with polylactide (PLA) and poly(butylene adipate‐co‐terephthalate) (PBAT) to prepare the biodegradable agricultural films. Through the optical performance, mechanical properties, and other research, the results showed that the rare earth complex could convert the sun's ultraviolet light to red light when doped polymer. Moreover, the relative intensity ratio of 5D0/7F2 to 5D0/7F1 of PLA/PBAT/EuTT film could reach 3.79, which implied that the film had strong fluorescence intensity and high color purity. The highest tensile strength of the film could reach 36.7/25.2 MPa, and the elongation at break was 462.8/483.0% in the machine and in the transverse direction when the added amount of Eu (TTA)3(TPPO)2 was 0.1 wt%. The tensile strength of the film was 33.3/20.1 MPa, and the elongation at break could reach 535.8/413.6% when the added amount of Eu (TTA)3(TPPO)2 was increased up to 0.3 wt%. Gel permeation chromatography showed that the Eu (TTA)3(TPPO)2 could cause depolymerization of polylactide, resulting in a decrease in the molecular weight of PLA. Furthermore, the crystallization ability of PLA was also improved. In this paper, the biodegradable films exhibited excellent ultraviolet light conversion ability and mechanical properties.
