The Serac Combox: Ideal for Single Serve Packaging
Serac has recently installed a new blow-fill-cap machine that fills 50g yogurt portions in an attractive fruit-shaped PET container.
Serac has recently installed a new blow-fill-cap machine that fills 50g yogurt portions in an attractive fruit-shaped PET container. By taking up the challenge of blowing and filling such a light and delicate package, Serac opens new perspectives for dairy and food manufacturers developing single serve packaging or lightweight bottles for the on-the-go consumer.
High precision stretch blow-molding with small preforms
Blown from a PET preform of only 2.3 g, with nearly half of the mass concentrated in the neck, the fruit-shaped container requires an expansion rate of 16 (4 times in both the length and the width), which is an extreme expansion rate in this industry. Using these small preforms, the SBL blow molder from Serac clearly demonstrates a high level of precision in heating, stretching and blowing operations.
Precise transfer system, ideal for light and unsteady packages
The 100% positive neck transfer system patented by Serac ensures that the packages will move along through the process without ever touching each other, which is a must in avoiding damage to the preforms. The Serac SBL blow molder can be directly coupled to most of the Serac filler machines due to a star-wheel system that compensates for the difference in pitch between the blowing and filling functions
Accurate filling and capping solutions
The slightest deviation under the filling nozzles can have dramatic effects. This is why Serac has included a servo-driven transfer system that ensures state-of-art positioning and filling accuracy. Serac has also designed a capping system that will accommodate oversized aluminium strips together with a new die press tool to achieve a hygienic and user-friendly seal.
