Every minute of downtime costs production time, material, and money. Regular maintenance may seem routine, but it’s one of the most effective ways to extend the lifespan of blown film equipment and keep output consistent.
Preventive maintenance (PM) means fixing small issues before they become major problems. Here’s how to keep your blown film line running reliably and efficiently.
Check and Clean Key Components
Dust, residue, and film fragments can build up around rollers, air rings, and dies over time. This buildup restricts airflow, causes uneven cooling, and leads to poor film quality. Schedule regular cleaning to keep airflow clear and die lips smooth.
Inspect heaters and temperature sensors, too. Faulty sensors can lead to overheating or uneven melt flow. Keeping these calibrated ensures consistent film thickness and clarity.

Monitor Bubble Stability and Cooling Systems
Fluctuations in bubble size or shape often indicate air leaks, worn seals, or blocked cooling channels. Check the air ring and internal bubble cooling (IBC) system for even airflow. Replace worn parts before they affect product quality.
If your line uses older cooling technology, upgrading to an energy-efficient model can improve bubble control and reduce power consumption. Swallow’s Blown Film Handling Systems are designed to integrate with modern cooling solutions to enhance stability and efficiency.
Inspect Rollers and Web Guiding Equipment
Worn or misaligned rollers can stretch or wrinkle film. Check bearings, shafts, and guiding systems regularly for wear or build-up. Replace any rollers showing uneven marks or reduced grip.
If your web guiding system is outdated, consider an upgrade. Automated Web Guiding Systems maintain consistent alignment and tension, reducing material loss.
Final Thoughts
A well-planned maintenance schedule keeps your equipment in top condition, improves film quality, and reduces downtime.
