Greiner Packaging develops innovative refill solution

Greiner Packaging is now offering a solution that is as smart as it is environmentally friendly: a sustainable refill bottle that can be used for liquids in spray bottles such as household cleaning products.

The bottle can be used for multiple refill doses, doing the work of four conventional spray bottles and trigger sprayers – a supremely simple and affordable way to cut down on plastic waste.

Refilling is one example of where sustainability starts. Why buy a new spray bottle every time you need household cleaner when there is now an efficient and eco-friendly way to refill your bottle? This was the motivation for Greiner Packaging to team up with its in-house design agency DesPro and develop a new refill concept for plastic spray bottles for household chemicals.

The many benefits of refilling

The newly developed 200-milliliter refill bottle is made of HDPE, PP, or PET material and weighs just around 16 grams in its original form. It contains 200 ml of concentrate, which later produces ten times its liquid volume across four spray bottle refills. Each safe, 50 ml dose can also be adjusted to 30 ml or 40 ml. This is done through a special valve and a guiding nozzlethat fits into all standard spray bottles. Thanks to their shape, the new refill bottles make it easy for consumers to squeeze out their contents in consistent doses – plus, they can be provided with an attractive label. In addition, the nonremovable, hinged snap-on lid is fitted with a safety lock. And a user-friendly level indicator completes the list of practical features. As a result, the newly designed bottle is well placed to meet all current market requirements.

Up to 85 percent less plastic used

Greiner Packaging is committed to advancing a sustainable circular economy that, in addition to recycling, also delivers reductions in plastic material use. Consumers can get as much out of a single new refill bottle as they otherwise could from four separate plastic spray bottles, including trigger sprayers – over its lifecycle, original 500 ml spray bottles and trigger sprayers can produce 10,000 individual 1-ml sprays, ensuring that they can be used to its maximum potential.  “It goes without saying that we were primarily aiming to reduce material use when we developed the new spray bottle multidose refill. The amount saved increases exponentially throughout the intelligent refill cycle – ultimately yielding a reduction of up to 85 percent. Each year, this could save up to 1,000 metric tons of plastic, if we assume that there are 20 million standard spray bottles a year. In order to be sustainable, reuse of a spray bottle and its refills must become a new normal,” says Tõnu Kundla, International Business Development Manager at Greiner Packaging. 

More eye-catching on the store shelf

The new refill bottles developed by Greiner Packaging and DesPro ensure a more eye-catching look at the point of sale than other refill packaging solutions simply because of their size. They also have a large surface area that can be designed or decorated attractively for consumers.
