Packing, marking, transportation, storage

Rubber briquettes are packaged in polyethylene film of trade M, H and T according to GOST 10354.
Paper four- layer glued bags of grade HM or BM at GOST 2226.
It is allowed to use polyethylene film and paper bags of all sorts with analogous characters.
For export rubber briquettes are packaged in one-layer polyethylene film and placed in wooden pallets.
In agreement with consumer, it is allowed to package rubber briquettes in two layers of polyethylene film and then in four-layer paper bags of all types.
The rubber is transported by all forms of transport in covered transporting means in accordance to all rules of cargo's transportation standing at transport of this form.
The rubber is stored at temperature not higher 30 (°C).
Shelf life - 1 year from date of production.
