Packaging 1.PTFE in double plastic bag outside hard drum packaging; packaging barrels are accompanied by labels, certificate, marked with a trademark, implementation of standards, varieties and grades, grade, batch number, net weight, date of packaging, inspector, packaging.
2.PTFE should be stored in a clean, dry warehouse, to prevent dust, water and other impurities mixed.
3 the goods are transported by non dangerous goods. In the course of transportation, we should avoid the heat, moisture, freeze or severe vibration, and excessive turbulence and extrusion.
