摘要
文中在大量实验数据的基础上提出了打孔薄膜透氧率的测定和计算方法。分别建立了单位面积LDPE(60μm)薄膜上孔径和开孔数与打孔膜透氧率的函数关系式。并就孔径和开孔数对包装油菜的保鲜效果的影响进行了研究探讨。
The method of measuring and calculating of oxygen transmission rate (Q3) for packaging film with aperture was put forward based on abundant experimental data.Equations of diameter of aperture with Q3 and number of aperture with Q3 were put forward too.The influence of aperture's diameter and number on fresh keeping effects of cole was studied and discussed.
