| Résumé : |
The Swiss injection molding machine manufacturer Netstal will produce double-layer barrier preforms for milk bottles and their 38 mm closures with tamper-evident bands at the Drinktec trade fair. As with all mass-produced products, cost-effectiveness was also paramount when designing the milk bottle and its closure, alongside maintaining food safety. This is further enhanced via a control circuit link between the injection molding machine and the Intravis CapWatcher III visual inspection system. |
| Note de contenu : |
- Flexible production system for single and double-layer preforms
- PET as a cheaper, more sustainable alternative to HDPE bottles
- The fitting closure for PET milk bottles
- Control circuit link opens up new possibilities
- FIGURES : 1. Prelactia preform (cross-section) : the gray interior layer produces the barrier effect - PET-line 2C : the secondary injection unit, with which the gray interior wall is injected, is positioned in an L position toward the main injection unit - 3. Prelactia mold : the dark component is put down first and covered by injecting the white exterior layer - A 32-cavity mold can produce approximately 29000 single piece closures per hour - each with a diameter of 38 mm and part weights of 2.8g |
