It consists in packing the classified fiber according to the technical specification required by the customer, in 50 or 60 kg blocks resulting from ensilage. The definition of the block weight is made as a function of the customer's requirement. The packaging process is subdivided into the stages of Packing, Transport System and Unitization.

PACKING - Since it is the final stage of the process, this place is rigorously controlled, aiming at ensuring a quality final product. It is comprised of two production lines: one line with thirteen pressure packers (PPs) and one palletizer for the exclusive production of asbestos cement types; the other line with seven pressure packers and one palletizer for the production of types directed to friction and millboard products and also with the possibility of producing the asbestos cement type. There is also an exclusive packer for production of the CB-7TF type, product used in the resin segment.

The classified fiber, from ensilage, is directed towards the pressure packer where it is weighted, pressed and packed with polypropylene raffia bags and internal polyethylene film. The formed block weights approximately 50 kg and has dimensions of 615 mm x 400 mm x 200 mm. For traceability purposes, at the output of each pressure packer, there is an identifier with the marking of the produced block. After packed, the blocks are positioned in the vertical position and in queue, on a sequence of roller conveyors towards the semi-automatic sewing machine, where the bag opening is sealed. After the sewing machine, the bags are identified with the batch number, which complies with the following sequence:

PP AMMDDAT HH, where:

PP – Product type (4K, 5K, 5R, 6D, etc.);
A – Production year (0 a 9);
MM - Production month (01 a 12);
DD - Production day (01 a 31);
A – Production sequence (A a Z);
T – Production shift (1, 2 ou 3);
HH – Production hour.

After being identified, still in the transportation system, the blocks pass through a dynamic scale to check their weight. In case there are blocks above or under the specified weight, they are discarded and re-processed.

After being sewed, identified, weighted and conferred, the blocks follow to the unitization.

UNITIZATION - In this stage, the blocks are handled automatically, forming a packed and plasticized unit, originating the finished product (PALLET).
The blocks are synchronized in the palletizer, which supports 5 blocks per layer.

After palletization, the units are transported to an automatic coverage system, where a polyethylene retractile film cover is placed on the pallet, for protection and stability of the unit.

After the plastic covering, the pallet is transported to the thermo-shrinking system, where the retractile film cover is heated, shrinking and packing the package. Finally, the finished product is made available for stock.
