Greiner Packaging creates liquid spray refill bottle for household plastic savings

04 Mar 2021 --- Greiner Packaging is releasing a refill bottle for liquid sprays, such as household cleaning products. The bottle can be used for multiple refill doses and replace four conventional spray bottles and trigger sprayers for cost and plastic savings.

The 200 ml bottles are made from HDPE, PP or PET and feature a practical flip-top cap with guiding nozzle for accurate and consistent dosing.

The Greiner Packaging team worked with in-house design agency DesPro to develop the refill concept for plastic spray bottles for household chemicals.

“We were primarily aiming to reduce material use when we developed the new spray bottle multidose refill,” says Tõnu Kundla, international business development manager at Greiner Packaging.

“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.”

“To be sustainable, reuse of a spray bottle and its refills must become a new normal.”

PackagingInsights and Innova Market Insights flagged “Reusable Revolution” as one of its top packaging trends for 2021.

According to Innova Market Insights, the majority of global consumers (52%) believe reusable packaging is a sustainable packaging model, followed by recyclable (50%), biodegradable (31%) and compostable (24%) (2021).Greiner Packaging’s refill bottle can be used for multiple doses, effectively replacing four conventional spray bottles or trigger sprayers for cost and plastic savings.

Lightweight convenience
The refill bottle weighs only 16 g in its original form and can hold 200 ml of concentrate, which later produces ten times its liquid volume across four spray bottle refills.

Each 50 ml dose can also be adjusted to 30 ml or 40 ml, achieved through a unique valve and a guiding nozzle that fits into all standard spray bottles.

The bottle’s shape makes it easy for consumers to squeeze out liquids in consistent doses. The packaging can also be provided with an attractive label.

Moreover, the non-removable, hinged snap-on lid is fitted with a safety lock, and a user-friendly level indicator completes the list of practical features.

Circular economy compliant
The refill bottles do not require outer packaging, further reducing material use. Furthermore, Greiner Packaging offers the solution made from post-consumer recycled (PCR), supporting the circular economy.

The packaging is also recyclable, including the lid valve, which can be mechanically separated in the recycling process.

When using labels for decoration, Greiner Packaging recommends selecting a compatible material enabling maximum recyclability.

For example, when using water-soluble adhesives, when considering the potential effect of the decorative material on the base material, and when assessing whether the decorative material may be separated from the base material due to the use of different material densities.

In other Greiner Packaging developments, the supplier recently launched a folded cardboard spoon, joined the international Alliance to End Plastic Waste and trialed yogurt cups made from 100 percent recycled material.
