Packing, Storge, Transportation

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 are brand, trademark, executive criterion, type, grade, lot No, and net content, pack date, checker, packager.

PTFE should be stored in clean dry warehouse to prevent from dust, moisture, etc, foreign matters.

The products are transported according to non-dangerous products, Heat, mositure, freezing and straong shock should be avoided during transprtation, Over-bumpiness and compression is apt to make the resin bind together.
