Ultimate Spray System
Truly sustainable aerosol spray system
Ultimate Spray System (USS)
- Spray system for next generation aerosols
- Fully recyclable spray caps with insert
- Mono-material: cap and insert made of PP
- Spray cap separated before disposal
Mono-material: PP insert
To realise a mono-material solution, WP developed an insert with a unique technology that can be made of the same PP grade as the spray cap. The spray cap including insert can be recycled 100% in standard waste streams.
Removable spray cap
Just a mono-material solution doesn't enhance circularity if the cap is not recycled in the dedicated waste streams. To remove the cap from the aerosol can before disposal, we developed an several intuitive separation features, like the outstanding zipper: the finger button can be lifted at which point the housing of the spray cap is torn open and can be removed.
Standard technology, suitable for customization
USS is a standard technology developed and patented by WP. It enables standard spray cap designs, but the technology is also highly suitable for customization. Personal Care and Home Care formulations have proven to give an excellence spray performance.
Closing the loop: ultimate circularity
To increase circularity further, the spray cap is also available in recycled PP (rPP/PCR). This reduces the amount of packaging waste and the use of fossil feedstock, resulting in a lower carbon footprint. The mechanical properties of PCR can match virgin material, making it a sustainable solution.
