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.

3The 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.
