Polypropylene (PP)
Product Description
The polypropylene granulate is a product of the processing of PP chips and consists of granules of uniform colour, without impurities. The granules have sustainable characteristics, processed from materials of reliable origin.
Production, control and packaging
- The PP granulate is produced in batches, with the batch being differentiated from the quantity produced per month.
The quantity produced is packed in big bags with a capacity of 1000 kg.
Each big run is analysed in the plant laboratory and the results are recorded in an electronic laboratory logbook.
Each big bag is identified by a label containing:
– Product name
– Manufacturer
– Quantity
– Date of production
– Number of the big bag
– BatchAn analysis certificate is issued on shipment, for each batch.
