While 2.2 billion people still do not have access to safe drinking water today, Bernhardt and its Denmark-based customer Solarsack have decided to act by using their expertise to offer a solution to a key issue: water safety. By combining our efforts, we have been able to develop an affordable water treatment solution using the sun's rays.
Two years after winning the PackTheFuture award in the Social Benefits category with our STERI-LIQUID POUCH, Bernhardt is awarded for the second time in a row in the same category for the 500-times reusable pocket produced for SolarSack. The purpose of this contest? Promote the creative and innovative potential of the plastic and flexible packaging sector: latest packaging innovations, new solutions, the latest technologies and trends in the sector... Born in close collaboration with the Danish company Solarsack, this product aims to promote access to drinking water for areas that are deprived of it.
Very easy to use, the Solarsack must, once filled with 4 liters of water, be exposed to the sun's rays for 4 hours... and that's it! Indeed, the combined action of UV-A, UV-B rays and the rise in temperature allows the destruction of pathogens present in water. Offering a real alternative to methods that consume coal or wood to purify water, the Solarsack is designed to be reusable 500 times, thus avoiding the generation of 600 kg of CO2 and saving 2 trees.
In addition to innovation from a social and ecological point of view, the Solarsack is also a technical innovation since its asymmetrical structure combines a very strong laminated film and a 5-layer co-extruded film offering excellent transparency to UV rays. The welding and insertion tools have been specially adapted to create a mechanically resistant and durable 4-litre pocket over time.
In conclusion, solarsack combines expertise in the design, production of film and pocket manufacturing to provide a solution to a major problem that is likely to increase in its final years: lack of access to drinking water.
