## Abstract The effects of postextrusion conditions (i.e., the draw ratio) were studied to control the cellular structure of extruded foams based on polymer blends. Highβdensity polyethylene and polypropylene were foamed with azodicarbonamide as a chemical blowing agent, zinc oxide as an accelerato
Samples of each of two high-density polyethylenes with various initial degrees of crystallinity, but otherwise identical, were exposed under a vacuum to moderate doses of gamma irradiation. The results indicate that, for otherwise initially identical polymer samples, the dose required to reach the g
## Abstract This study investigated the influence of highβpressure processing on the morphology and permeability of lowβdensity polyethylene (LDPE) films used for food packaging. This was done by monitoring the crystallinity, melting temperature (__T__~__m__~), and oxygen transmission rate (OTR) of
