The free radicals produced by β₯ irradiation in the polymer network are formed with ionizing radiation. The decay rates of radicals in the temperature range were used to estimate the diffusion coefficient of oxygen into polymeric spheres by an electron spin resonance (ESR) technique. The ESR results
## 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
