Do the supplied containers need to be cleaned before filling?

Whether a bucket or cup needs to be cleaned before filling depends on the intended application, the filling product and the hygiene requirements of the filling operation. Our packaging is manufactured under controlled production conditions and packed for transport and storage. However, it is not supplied as sterile packaging.

During production, packing, transport, storage and handling, contamination such as dust or particles cannot be completely excluded. The filler should therefore determine, as part of its own hygiene and quality concept, whether cleaning or another treatment is required before filling and which process is appropriate.

For food applications, factors such as the type of food, subsequent processing, storage conditions and the hygiene requirements of the filling process should be taken into account. Depending on the application, blowing out with suitably filtered air, rinsing or another defined cleaning or hygiene step may be appropriate.

Important: Food contact compliance of a bucket or cup does not mean that the packaging is sterile or can be used without further hygienic assessment in every filling process. Food contact compliance and the hygienic condition of the packaging must be assessed separately.

For microbiologically sensitive filling products or applications with particularly high hygiene requirements, the necessary process should be defined by the filling company in accordance with its HACCP or hygiene concept and, where appropriate, validated.

If cleaning or disinfection is carried out, it is also important to ensure that the process and any cleaning or disinfecting agents used are suitable for the respective packaging material and the intended application.

Cleaning before filling – what should be considered?

Application What should be considered? Recommendation
General applications During packing, transport, storage and handling, dust or other particles cannot be completely excluded. Before filling, check whether the hygienic condition of the packaging is appropriate for the intended application.
Food applications The required level of hygiene depends, among other factors, on the food, the filling process, subsequent processing and storage conditions. Define the required cleaning or hygiene step as part of the company's hygiene or HACCP concept.
Microbiologically sensitive filling products Sensitive products may require a higher hygienic standard for the packaging prior to filling. Use a process suitable for the specific application and validate it where appropriate.
Blowing out Blowing out may be used to remove loose particles, but it does not constitute sterilisation or disinfection. Use only suitably treated or filtered air and integrate the process into the company's hygiene concept.
Rinsing / cleaning A cleaning process may be required depending on the application. The packaging material, temperature and cleaning agents used must be taken into account. Use only processes and agents that are suitable for the respective packaging material and intended application.
Food contact compliance Food contact compliance describes the suitability of a material for its intended contact with food. It does not mean that the packaging is supplied sterile. Assess food contact compliance and the hygienic condition of the packaging separately.
Responsibility of the filler The required hygiene measures depend on the specific filling and production process. Include cleaning, handling and filling in the company's hygiene and quality concept.

Important information

Food contact compliant does not mean sterile. Whether a bucket or cup needs to be cleaned or otherwise hygienically treated before filling must be assessed on the basis of the specific filling product, filling process and operational hygiene requirements.

For microbiologically sensitive products or applications with particular hygiene requirements, the necessary process should be defined by the filling company and validated where appropriate.
