纸浆模塑工业包装制品（简称纸模）主要用于缓冲包装，它以回收的废弃纸张为原材料，具有质轻、易降解、透气性好等优点。

Pulp-molding packaging products (pulp mold) are made of recycled trash paper, and used in cushion package and have the advantages of light mass, easy decomposability, good ventilation and so on.

因此，对软包装材料透气透湿性（或阻隔性）的测试研究在包装测试中越来越重要。

Therefore, water vapor permeability of flexible packaging material (or barrier) of the test of testing more and more important in the packaging.

采用低透气性的包装材料进行真空包装或添加脱氧剂包装，可明显抑制过氧化值和酸价的增加速度，延缓酸败。

Compared with the control, the vacuum package or adding deoxidant package with materials of low venting quality can constrain the accelerating speed of PV and AV, and delay rancidity.
