Effects of Machine Direction Orientation (MDO) on the Moisture and Oxygen Barrier Properties of HMW-PE Films

摘要

Moisture and oxygen barrier properties of machine direction oriented (MDO) polyethylene films have been studied. This paper will present the effects of density and draw ratio of the MDO film on its barrier properties. This paper will also present the structural changes occurring in the crystalline phase of the MDO film and its relationship with the barrier properties.
