How does DUO work
With the DUO concept, you are able to seal two different packs in different heights and shapes at the same time. It is perfectly tuned to products consisting of two components, which need to be sealed individually. As an example, a round tray and corresponding lid can be filled with different products, after which they are both sealed with a top film. SEALPAC’s InsideCut system, which ensures that the film is neatly cut on the inside of the tray, allows for a perfect fit of the combined parts after sealing.
Highly efficient
By minimizing the changeover times, increasing flexibility and offering product versatility, SEALPAC’s innovative DUO tooling will boost the efficiency in your packaging process even more.

FAQ over DUO
-
What benefits does dual-compartment packaging offer?
DUO allows for an attractive presentation of multi-component products, which are sealed individually and then clicked together for an attractive presentation.
-
Which products can be combined in one pack?
Any multi-component product, such as yoghurt with muesli, snacks with cheese and nuts, etc.
-
How is product separation maintained?
Each component is sealed individually, optionally under modified atmosphere for prolonged shelf life. As such, DUO allows for individual opening of each single compartment.
-
Does it affect shelf life or product interaction?
As the DUO concept is suitable for modified atmosphere packaging, it achieves the same shelf-life dates as traditional trays. Furthermore, owing to their consistent sealing process, SEALPAC traysealers always guarantee highest seal integrity and maximum shelf life.
-
What are the sustainability considerations?
With the DUO concept, you are able to seal two different packs in different heights and shapes at the same time. As with any kind of packaging, materials used should be as thin as possible and recyclable (e.g. mono materials). As packaging experts, we would gladly sit down with you to design the optimal pack for your application.
