Resumo
The integrity of materials containing packaging (natural or synthetic polymers) is essential to keep the aseptic
condition of commercialized products (health care products, food and pharmaceuticals). The objective of this
paper was to study gamma radiation effects (25 kGy, 40 kGy and 50 kGy) on the main properties of paper and
multilayer films (polyester and polyethylene). Paper and multilayer films are components of packaging
(pouches) for radiation sterilization containing medical equipment or products. Paper was the more radiation
sensitive among the studied materials and radiation effects were more pronounced at brightness, pH, tearing
resistance, bursting strength and tensile strength. Concerning plastic film, no pinholes were induced by
radiation and the effects on the tensile strength were not significant. Although the seal strength packaging
(pouches) decreased according to increasing dose, the sealing integrity was preserved.
