Transparent Food Container with Barrier
Ferromatik Milacron GmbH, Malterdingen, Germany, demonstrates its competence in the field of multicomponent technology by presenting a cost-efficient concept for barrier injection molding of thin-walled packaging. This is performed with a complete system, consisting of an F 220 injection molding machine (clamping force 2,200 kN) with Kortec co-injection technology and a "Multi" injection unit from Mold-Masters as ancillary unit. With a four-cavity mold, the system produces cups for fruit conserve.
The cups are made of PP with an ultrathin EVOH layer at their core. This layer serves as a barrier, permitting long shelf lives. The system components are controlled so that the two plastic melts generated in the injection units are superimposed via the hot runner and needle valve technology, and solidify in the injection mold to produce a barrier package. This application is interesting not only for the packaging industry, but also for medical technology.
For other applications in medical technology, Ferromatik Milacron presents specially equipped injection molding machines. This includes stainless steel cowls and FDA-compliant lubricants and, on request, GMP documentation. This primarily takes into account hygiene aspects. An F 120 equipped with an APh 35 injection unit and a three-zone screw, with a highly efficient needle separation system and a four-cavity mold from Zahoransky Formenbau GmbH, Freiburg, Germany, produces disposable syringes with needles without using an adhesive bonding operation (Fig.). For the purpose, the needles are inserted into the mold, aligned and overmolded. In parallel with the phase of inserting the needles in one mold half, the molded parts are removed in the second parting plane.
By eliminating oil, the Elektron-series machines are especially suitable for producing medical products and food packagine – including in a cleanroom. As evidence of this, an Elektron 30 machine with an international size 55 injection unit produces carriers for 1 ml ampoules in a cycle time of 9.1 s during the trade show. A four-cavity mold from Braunform GmbH, Bahlingen, Germany, is used for this.
