Ensuring Consumer Safety
As the events industry moves away from single-use plastics, questions regarding the hygiene of reusable alternatives are natural. Consumers expect the same level of cleanliness from a reusable festival cup as they do from a glass in a restaurant. Ensuring this standard requires a combination of correct product design and professional washing protocols.
Design for Hygiene
A hygienic cup starts on the drawing board. Our cups are engineered to facilitate effective cleaning:
- Surface Finish: We use high-gloss polished moulds. This creates a smooth surface that resists staining and prevents residue from adhering, making the wash process more effective.
- Geometry: The internal curves of the cup are designed to prevent water pooling. Sharp corners are avoided to ensure that wash jets can reach every part of the vessel.
- Stacking Vents: When cups are stacked while damp, mould can develop. Our cups feature engineered stacking lugs or ribs that ensure an air gap between nested cups, promoting airflow and thorough drying.
Professional Washing Standards
Reusable cups at large events are typically cleaned in industrial washing tunnels. These machines operate at high temperatures (sanitising phase often exceeds 80°C) and use commercial detergents.
| Wash Phase | Function | Key Benefit |
|---|---|---|
| Pre-Wash | High-pressure rinse | Removes physical debris/dregs. |
| Main Wash | Detergent at 60°C+ | Chemically cleans and removes grease/lipids. |
| Sanitisation | Rinse at 80°C+ | Thermal disinfection of the surface. |
| Drying | Air knives / Heat | Removes moisture to prevent bacteria growth. |
Safe for Public Use
When these industrial processes are followed, reusable cups achieve a level of microbiological cleanliness that meets or exceeds food safety standards. The combination of non-porous Polypropylene and high-temperature washing ensures that reuse is a safe, hygienic, and sustainable option for mass gatherings.
