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

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

3. The product are transported according to non-dangerous products. Heat, moisture, freezing and strong shock should be avoided during transportation. Over-bumpiness and compression is adapt to make the resin bind     together.
