16 packing, storage transportation 1、ptfe is packed in double layer pvc bags inside and in
hard circular barrels outside, on the barrel, there should
be attached label and quality certificate, on which there

from dust, moisture, etc. Foreign matters.
3、the products are transported according to non-dangerous
products, heat ,moisture, freezing and strong shock
