Packing,Storage,Transporation
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,.
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.
