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.
