By compressing the aerosol, Unilever has reduced the weight from 16% to 33%. The new packaging uses 20% less aluminium and lowers carbon footprint by 20% per bottle. Thanks to the new spray system, the compressed deodorant lasts as long as the old bottles. This major technological innovation is not covered by a patent and Unilever has therefore opened it up to the entire sector. Thanks to this transparency, the whole sector could benefit from even greater environmental gains.
The foam technology has been developed in close collaboration between Unilever, Mucell Extrusion and Alpla. This is the first time this technology has been applied to HDPE bottles. It enables the creation of a foam layer (containing air) sandwiched between two layers of 'solid' HDPE. It remains a mono-material HDPE bottle. The weight has been reduced by over 14% from 21g to 18g. Over a full year and for Europe only, this represents a saving of around 275 tonnes of HDPE.
The coffee capsules were packed in cardboard boxes of 10, each individually wrapped in a plastic film. They are now in a plastic bag that contains 16 capsules, the weight of which is lower than all the individual packages, and the cardboard box has been eliminated.
The previous packaging has been replaced by a cardboard 'display' box. The consumer therefore benefits from 100% recycled packaging made of renewable materials (100% FSC certified) with a better storage life.
Flexible packaging which is lighter, water-resistant and robust, with a special stopper to ensure the correct dose, has been chosen for the entire seed range (8 products). By measuring out precise quantities and ensuring a longer storage life, this packaging leads to less food wastage.
Thermoformed tray, without lid with product densification.
The thermoformed tray no longer needs a lid, which is the first means of weight reduction. The density is higher: 110 items as compared to 80. This brings a second weight reduction per item, or a total saving of 54%. The tray can be reused at least five times.
