Specifically for aseptic food products, SIG Combibloc has introduced carton packs with a perforation all the way across the top. Thanks to the complete perforation, the carton pack can be opened all the way across the top without the use of additional tools and every last drop of the product can be fully emptied out. This makes the carton packs suitable for chunky and highly viscous products.
Surveys show that consumers rate easy opening as a high priority when it comes to food packaging. In a direct comparison between fully perforated carton packs and food metal cans with ring-pull, the carton pack scored significantly higher in terms of ease of opening.
combiblocCompact is the first package format. It is available in volumes from 200 to 500 milliliters.
To provide the full perforation, a small adjustment needs to be made to the filling machine, using the appropriate modification kit. The food manufacturer can then fill products in carton packs either with complete perforation or without. For greater ease of handling, the carton gable has been made 5 millimeters higher, giving the consumer a firmer grip when opening. Because the carton packs are the same size and shape with and without the full perforation when filled in identical volumes, there is no effect on secondary packaging or transport.
