Packing,Storage Transporation

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.

PTFE should be stored in clean dry warhouse to prevent

from dust,moisture,etc,foreign matters.

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
