- Abstract
This study investigates the effect of extrusion processing conditions and comonomer type on the gas permeation properties of LLDPE films containing polyisobutylene (PIB). The results show improved gas barrier properties with increasing polymer density and with increases in film crystallinity and orientation as a result of extrusion processing conditions such as blow-up ratios.
