Direct answer
Record the condition at the machine. Temperature, humidity, air quality, pressure, voltage and extraction can change product behaviour and equipment repeatability. For case packing, confirm the result with representative product and packaging before altering several variables at once.
Likely causes
- Product condition changes with temperature or humidity in the case packing process.
- Compressed air quality or pressure is unstable in the case packing process.
- Voltage, extraction, water or drainage is insufficient in the case packing process.
- The machine is tested in different conditions from production in the case packing process.
What should be checked first?
- Record conditions during good and bad runs
- Check utilities under peak load
- Measure product temperature and humidity exposure
- Inspect air quality and pressure drop
- Verify extraction and drainage
- Define operating limits
- Repeat trials at worst normal conditions
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.

Sealing and end of lineWhy is case packing production giving inconsistent results?
Variation usually begins with changing product or packaging conditions, unstable presentation, unsuitable settings or wear in the process.

Sealing and end of lineHow can I increase case packing 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.
