Greiner's plastic fresh clip allows the user to reseal a carton after it has been opened. This keeps cereal, muesli, and similar foods fresh for longer, actively helping to prevent food waste.

The combination of cardboard and plastic means usage of both materials is reduced to a minimum. At the same time, the solution ensures that the contents are given optimum protection against moisture, pests, and spoilage.   Using as little plastic as possible

The fresh clip is produced using the injection molding process. It features a sealing surface onto which a plate element made of plastic, cardboard, or aluminum can be affixed – this ensures the package’s original appearance on retail shelves and enables the clip function once it has been removed. The creases positioned around the clip allow the packaging to be clipped together and sealed. The fresh clip can be attached to the carton in such a way that it can either be removed or remain affixed. There is the option to attach the clip permanently with adhesives, and interlocking or mechanical connections could be integrated as well. Reducing the plastic content was central to the clip’s design. A variety of finishing methods – from gloss, matte, and metallic to textures and tactile elements – can be used to attract more attention at the point of sale. A clicking sound signals that the clip is completely sealed. 

The packaging is also easy to use. The contents of the carton can be accessed by simply pulling off the plate element. To seal the packaging again, the two grips on the sides are pressed together until the clicking sound is heard. The packaging’s gapelike opening is also an aid to dispensing and pouring out the contents.   


In cooperation with Austria’s Federal Ministry for Sustainability and Tourism, the Federal Ministry for Digital and Economic Affairs awards the “Staatspreis Smart Packaging” (National Award for Smart Packaging) every two years. This year, Greiner Packaging took home the Special Award for Innovation for its “fresh clip” solution. The award ceremony took place at “Österreichischer Verpackungstag” in Vienna, an event focusing on Austria’s packaging industry. More than 60 entries in five categories were submitted for the award this year.
