Abstract

Two polyethylene samples, one (PE-10) blended with 10% hydrogenated petroleum resin (HPR) and one (PE-0) blended without HPR, were used to investigate the structural evolution and deformation behavior during sequential biaxial stretching and the properties of films after stretching. During the process of stretching in the machine direction (MD), the addition of HPR affected the movement of molecular chains and the slip and rearrangement of lamellae, the orientation rate of the samples slowed down, and the fibril structure and voids reduced. During stretching along the transverse direction (TD), the molecular chains and lamellar structure orientation of PE-10 samples were faster, due to the less fibrillar structures and voids. In addition, the mechanical properties and puncture resistance of PE-0 and PE-10 samples after biaxial stretching were excellent, and the mechanical properties of PE-10 film in TD direction were slightly better than that of PE-0 film.
