目的观察纸塑袋包装物品用环氧乙烷灭菌效果及其对保存期的影响。方法采用无菌检验和化学监测方法进行环氧乙烷灭菌后和保存期间无菌质量检测。结果经环氧乙烷灭菌后的纸塑包装袋内指示卡和袋外指示色块变色全部合格。灭菌处理的纸塑包装物品保存9个月后,3M纸塑包装袋检出一次细菌阳性;芬兰WIPAK纸塑包装袋出现1次阳性。大可纸塑包装袋保存6~10个月后检出4次阳性。结论环氧乙烷对纸塑包装物品可达到灭菌要求;但保存期限不同。
Objective To observe the sterilization effect of ethylene oxide on paper-plastic bags and its effect on shelf life. Methods Aseptic and chemical monitoring methods were used for sterility testing after ethylene oxide sterilization and during storage. The results of ethylene oxide sterilized paper and plastic packaging bags within the instruction card and bags outside the color discoloration of all qualified. Sterilized paper-based packaging items stored for 9 months, 3M paper and plastic bags detected a positive bacteria; Finland WIPAK paper and plastic bags appeared a positive. Large paper can be stored in plastic bags 6 to 10 months after the test detected 4 positive. Conclusion Ethylene oxide can achieve sterilization requirements for paper-plastic packaging items; however, the shelf life is different.
