Compostable control

The concept is the work of designer Fabrice Peltier and is well worth a 2024 packaging Oscar which he won in the “emerging materials” section: Seelcap Onego is a biodegradable tamper-evident indicator for bottles with OK Home Compost certification is in progress. The piece completely disintegrates under composting conditions, even at room temperature, in less than 6 months. Another advanced ecological advantage: the system would reduce the carbon footprint by up to 70% compared to conventional heat-shrinkable capsules.

The innovation, which primarily targets the wine and spirits sector, was presented at the Luxe Pack Monaco 2024 trade show.

Two distinct but inseparable parts

This is also the first fruit of a recently announced partnership between Sleever and Carbios. Seelcap Onego is made up of two distinct but inseparable parts: the first to ensure tamper-evidence and the second to allow easy opening in a single movement with a grip tab. “The revolutionary nature of this double innovation lies on the one hand in the integration into the biopolymer mixture of the encapsulated Carbios Active enzyme, the solution developed by Carbios for the biodegradation of PLA, and on the other hand in its eco-designed design” , adds a joint press release.

“Due to its small size, less than 60 mm, the tamper-evident system does not fit into traditional packaging sorting and recycling flows, hence the need, support the two companies, for a new biodegradable alternative” .

Finally, it integrates easily into existing packaging lines and remains compatible with installation and retraction equipment such as Combishrink and Combiskinner offered by the Sleever Group with rates of 60 to 24,000 bottles per hour.
