| 中文摘要: |
| 目的 研究无菌包装袋的透氧率与其厚度、材质及温湿度的关系。 方法 用厚度测试仪测量无菌包装袋厚度，用红外光谱仪检测材质、用氧气渗透测试仪测试透氧率，并比较厚度、材质和温湿度对透氧率的影响。结果 无菌包装袋的透氧率随厚度的增加而减小；材质对无菌包装袋的透氧率影响较大；无菌包装袋的透氧率随着温度的增加而增加，阻氧性能下降。 结论 无菌包装袋的厚度、材质和环境温度对其透氧率均有影响，而相对湿度对透氧率无显著影响。 |
| 英文摘要: |
| This work aimed to study the oxygen transmission rate of aseptic packaging bags with different thickness, materials, temperatures and humidity. The thickness of aseptic packaging bags was tested by film thickness gauge; the materials were detected by infrared spectrometer; the oxygen transmission rate was tested by OX-TRAN Model. And the influences of the thickness, material and temperature and humidity on the oxygen transmission rate were compared. The oxygen transmission rate of aseptic packaging bags decreased with the increase of the thickness. Material had significant effect on the oxygen transmission rate of aseptic packaging bags. The oxygen transmission rate increased with the increasing temperature and the gas barrier properties decreased. The thickness, materials of aseptic packaging bags and ambient temperature all had impacts on the oxygen transmission rate, while the humidity had no significant effect on the oxygen transmission rate. |
