Direct answer
Cleaning must suit the product, materials, contamination risk and machine design. Use an approved method that reaches product-contact and trap points safely. For cartons, confirm the result with representative product and packaging before altering several variables at once.
Likely causes
- The cleaning method does not reach trap points in the cartons process.
- Product-contact materials or seals are unsuitable in the cartons process.
- Disassembly and reassembly are inconsistent in the cartons process.
- Cleaning acceptance is not defined in the cartons process.
What should be checked first?
- Identify all product-contact and splash zones
- Follow isolation and approved chemical procedures
- Document disassembly order and settings
- Inspect seals, hoses, valves and dead legs
- Define visual, swab or rinse acceptance as required
- Record time and repeat faults after cleaning
- Verify the first good production after reassembly
What should you compare before buying?
Compare the operating principle against the actual product, pack range, sustained good output, measurable quality limits, cleaning, changeover and site conditions. Use representative samples and agree what will be demonstrated during testing before delivery and after installation.

Packaging materials and formatsHow can I increase cartons production speed?
Increase sustained good output by identifying the actual constraint, separating machine cycle time from handling time and removing the first recurring cause of waiting.

Find the first point where control is lost. A downstream alarm is often only the final symptom of poor feeding, transfer, detection or format control.
