PACKING
Each bobbin is wrapped up with PE foil. Bobbins are placed onto pallets with forming a block-pack. Block-packs are stretch-foiled. Standard block-packs are formed on pallets:
– 1200×800 mm (6-layers block-pack)
– 1200×1000 mm (5-layers block-pack)

TRANSPORTATION   
Block-packs are carried in 40’ containers and trucks.

Each bobbin with yarn is wrapped up with paper or polymeric foil. Bobbins are put onto a pallet with forming a block-package using interlayers   while palletizing. A cover is put on the top of block-package. A block-package is strapped and stretch-foiled.

Quality control is performed according to the regulations of JSC «Grodno Azot» in force.

Min. 500 meters of upper yarn layer should be unwound from each bobbin before starting tests.
