The neat PLA film formed a strong
film with high TS of 62.0 MPa, however, the neat PBAT film formed a
mechanically weak film with TS of 9.4 MPa. Generally, PLA film
exhibited higher strength, while PBAT possessed lower strength
compared to those of commodity plastic films such as high density
polyethylene (22-23 MPa), low-density polyethylene
(19e44 MPa), and polypropylene (31-38 MPa)
