Effect of processing conditions on properties of heat-sealed sterilized bag

摘要

Sterilized bag has been developed to prevent hospital infection. Normally the bag consists of plastic film and sterilized paper. Plastic film bag are made by heat seal method. When the seal strength is weak, the sterilant is lost. Instead, when the seal strength is too strong, the tearing fracture of the paper and the film occurs. Processing conditions such as heat sealing temperature, pressure, and so on greatly affect mechanical properties of heat sealed part. In this study, the mechanical properties of the heat sealed part of a sterilized bag were examined using peeling test and SEM.
