Shrink tunnel airflow guide
Shrink tunnel airflow influences how evenly the film shrinks around the pack. Temperature alone is not enough for a good finish.
When this search applies
Shrink tunnel airflow influences how evenly the film shrinks around the pack. Temperature alone is not enough for a good finish.
- Airflow around all pack sides
- Temperature and speed balance
- Avoid overheating products
- Consistent pack spacing
Airflow and presentation
A poor finish may be caused by airflow, speed, film type or pack spacing rather than temperature alone. The tunnel should be adjusted as part of the whole process.
Product protection
Sensitive products need careful control so shrink film tightens without overheating the carton or contents.

FAQ
Shrink tunnel airflow guide FAQs
Should I simply increase temperature?
Not always. Higher temperature can distort film or damage products if airflow and speed are wrong.
Does pack spacing matter?
Yes. Packs too close together can block airflow and cause uneven shrink.
Can this be solved during setup?
Often, yes. Trial settings help find the right balance.
