摘要
对经过不同温度和时间处理的蒸煮袋PET/BOPA/CPP的阻隔性能和断面结构进行了研究,发现经处理的蒸煮袋的透湿率、透氧系数发生了明显的改变,数据随处理温度和时间的增加而增大;内部结构也因受到高温蒸煮而受到不同程度的损坏。
The barrier properties and cross section structure of the retort pouch PET / BOPA / CPP was studied after the different temperature and time.The result showed that the vapor permeability rate and oxygen permeability rate were changed significantly;the internal structure of the retort pouch was damaged by high temperature.
