*6、Packing,Storage Transporation： （1） PTFE is packed in double layer PVC bags indide 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 warhouse to prevent from dust,moisture,etc,foreign matters.

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