　　3 [Preventing products from becoming dry and dry], using its hydrophilicity, can prevent the product from having water loss and dryness, poor taste, will not damage the packaging prototype due to water absorption, and prevent natural loss (weight loss) of quantitative products (weight loss) Essence The resistance of the gas block does not change with the change of humidity, even if the high humidity environment will not cause the product to deteriorate;

　　4 [Preventing the taste of the product], using its low permeability to prevent fragrance loss, and does not absorb the residual odor and abnormal taste, which can ensure the integrity of the smell (this is especially important when packaging low -fat or high -protein foods. To.

　　5 [Prevent the damage rate of the packaging bag], have good puncture resistance, fatigue resistance, cold resistance, high temperature resistance 121 ° C-135 ° C. Its mechanical barriers are not reduced, stretching is strong, and it is good Thermal contraction function avoids the return phenomenon caused by bumps during the sales process
