摘要：The present disclosure provides a coextruded multi layer film. The coextruded multilayer film includes a core component having from 15 to 1000 alternating layers of layer A and layer B. Layer A has a thickness from 30 nm to 1000 nm and includes a propylene- based polymer having a crystallization temperature (TIc). Layer B includes a second polymer having a glass transition temperature (T2g), wherein l/ c <T2g. Layer A has an effective moisture permeability less than 0.40 g-mil/100in2/day.
