Overmolding process for preforms honored at Emballage

At the Emballage packaging trade show in France last autumn, injection/blowmolder PDG Plastiques (Malesherbes, France) was awarded the 'Oscar de l'emballage' (packaging Oscar) for its work in development of PRElactia performs and market introduction of bottles blown from these. PDG's injection molding machinery supplier, Switzerland's Netstal, Spanish moldmaker Molmasa, PET supplier Novapet, and dairy cooperative LSDH also shared in the honor.

The PRElactia overmolding process is said to guarantee the light barrier required in ultra-high temperature (UHT) milk bottles. Molding of the preforms begins with injection of an inner, grey layer, which is then overmolded by a second, white layer. These preforms weigh just 21g for 1L milk bottles, about 7g less than the standard for this size UHT milk bottle. PDG Plastiques molds the performs on a Netstal SynErgy 2400-2150/900 equipped with a Molmasa mold.—[email protected]
