Physical and mechanical properties of products:
1.Product appearance: smooth surface, uniform thickness, no obvious spots, no oil traces, impurities, fold printing.
3.Thermal shrinkage Rate：Test under 100 ℃, transverse shrinkage 48±3%, longitudinal 12±3% can close to the product.Can be used heat shrinkage machine shrinkage, can also be used hair dryer, boiling water shrinkage.
4.Flexible performance：After the packaging shrinkage, from 1 meters high from different directions fell to the cement floor three times, there is no cracking phenomenon.
5.Color：After the packaging shrinkage, under 30 ℃ environmental conditions to store, do not occur fading, discoloration and other color changes.
6.Tensile: Less than 2%.
7.Water absorption rate ≤ 0.5%.
8.Natural shrinkage Rate:Environmental storage Under 30 ℃,Natural shrinkage ≤ 0.5%.
9.Resistance coefficient≥1×1015Ω/cm3（Relative humidity at room temperature≤65%.
