SUSTAINABLE PRODUCTS FOR EVERY APPLICATION
The majority of bottles, barrels and containers are manufactured by blow moulding.
The Granic mineral masterbatches can be used for the manufacture of this type of packaging, even those containing food, given that Granic is suitable for contact with food.
In addition to costs reduction on the final formula for the bottle or drum, the mineral masterbatches from GCR Group are, above all, noteworthy as they maintain and even reduce the dispersion of values in the top load test.
In Figure 1 the top load of a bottle manufactured from high-density polyethylene (HDPE) and another containing 20% of Granic is compared. Furthermore, in the bottles containing the Granic mineral masterbatch, the density of the walls is reduced so the final weight is the same. The results show a greater consistency in the top load test with the bottles manufactured from Granic.
The Granic masterbatch also has a lower carbon footprint than virgin polymers, as certified by TÜV Rheinland, which results in products (bottles, drums, containers, etc.) that are more environmentally friendly and sustainable.
