Packing, Storage, Transportation

1PTFE is packed in double layer PVC bags inside and in hard circular barrels outside.On the barrel,there should be attached lable and quality certification,on which there are brand,trademark,executive criterion,type,grade,lot No.and net content,pack date,checker,packager.

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

3The products are transpored 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.
