The purpose of this study was to evaluate the influence of the material and volume/different
finish diameters in the moisture and oxygen barrier properties for bottles for pharmaceutical
products. Samples of glass, polyethylene terephthalate (PET) and high-density polyethylene
(HDPE) bottles with different volumes (30, 60 and 120 cm 3) and finish diameters (18, 24
and 28 mm) were studied. It was previously verified that the integrity of the closure was not
dependent on the torque applied to the polypropylene (PP) cap and not influence the barrier …
