Highly moisture-permeable and water-blocking series of PTF packaging materials

PTFPackage highlights: The PTF material used in the product is a new high-tech material, water vapor can completely pass through the material to meet the rapid moisture absorption requirements. In addition, the molecular density of the material is higher than that of water molecules, so it can prevent 100% of the calcium chloride solution formed after the calcium chloride absorbs moisture from leaking out.。


Unique material properties, known as a breathing envelope。


High molecular density of the product, with strong water molecule barrier performance, can completely block the liquid water。

PTF Membrane:Its structure is made of pure PP or PE pellets through stretching process。

Small and tight pores on the surface of the material, into a sponge structure, can effectively block liquid water; at the same time has the characteristics of permeable gaseous water molecules and small molecules (aromatics), mostly used for functional layer。
