Abstract
The effect of the crystalline structure (crystallinity and crystallite size) on the light transmissivity in low-density polyethylene sheets has been studied. Wide-angle X-ray diffraction, DSC, and UV/visible spectroscopy techniques have been used. The increase in crystallinity enhanced the light transmissivity in the visible region, but no significant effect in the UV region was obtained. The crystallite size showed no clear relation to transmissivity.
