Packaging materials are mostly made of high molecular polymer processing, general disinfection, can only destroy pathogenic microorganisms, and can not kill spores, only sterilization, can completely kill bacteria, spores, and even achieve medical equipment required Sterility level.

And in view of most of the polymer heat resistance, high pressure resistance, can at room temperature and pressure to achieve sterilization effect of irradiation sterilization, has become most manufacturers of choice.

The wide application of plastic products in medical devices makes sterilization a key standard to measure whether plastic products can be used as medical device materials. Commonly used materials suitable for irradiation are polystyrene, polypropylene, etc.

In addition to medical devices, food, drugs, cosmetics and other packaging materials, can be used irradiation sterilization, according to the product's initial contamination of bacteria and microbial indicators to confirm the product's sterilization dose, to achieve different sterilization requirements.
