Mastering Blown Film Handling: Top Tools for Seamless Production
In the packaging industry, blown film production plays a key role in making strong, flexible film for polybags, wraps, and other products. However, producing high-quality film is not just about the extrusion process. The tools you use to handle the film after extrusion can make a big difference in your production line’s success.
At Swallow Machinery, we are a trusted stockist and distributor of web processing solutions and accessories. We work with businesses across the blown film and polybag-making industries to improve efficiency, reduce waste, and keep production running smoothly. In this post, we will explore the top tools you need to master blown film handling and achieve seamless production.
What Is Blown Film Handling?
Blown film handling refers to the steps taken after the film is formed. These steps include cooling the film, collapsing the bubble, guiding the film through rollers, and finally winding it into rolls. For polybag production, additional steps like cutting and sealing are also involved.
Handling this process correctly is important for film quality and efficiency. Poor handling can cause wrinkles, film breaks, uneven rolls, and even machine damage.
Why Do the Right Tools Matter?
Using the right tools can improve the way your film moves through the line. The correct equipment helps reduce waste, speed up production, and improve product quality. It also minimises downtime caused by film jams or machine issues.
At Swallow Machinery, we carry a wide range of tools designed specifically for blown film and web processing. Below are some of the most important tools to consider for your production line.
1. Web Guiding Systems
Web guiding systems help keep the film aligned as it moves through the machine. Even small shifts in film position can cause defects or waste.
These systems automatically adjust the position of the film to keep it centred. This helps reduce edge trim, improve winding accuracy, and create a cleaner final product. We offer reliable web guiding systems that are easy to integrate into your existing line.
2. Air Shafts and Chucks
Air shafts and chucks are used to hold the film rolls tightly during winding or unwinding. A secure grip is important for smooth, consistent winding.
With high-quality air shafts, you can expect faster roll changes, tighter rolls, and safer operation. Swallow Machinery offers durable, easy-to-maintain air shafts and chucks designed for high-performance production.
3. Nip Rollers
Nip rollers help flatten and pull the film through the line. They are also used to collapse the bubble after it is cooled.
These rollers must apply even pressure and have a smooth surface to avoid damaging the film. Proper nip roller setup improves film thickness consistency and reduces wrinkles. We provide several nip roller options depending on your film type and speed requirements.
4. Tension Control Systems
Maintaining the right tension is key to smooth blown film handling. Too much tension can stretch or tear the film. Too little tension can cause sagging and poor winding.
Tension control systems automatically adjust the speed of rollers to maintain consistent pressure. These systems improve film quality, reduce waste, and produce cleaner rolls. Swallow Machinery supplies advanced tension control solutions for blown film lines of all sizes.
5. Anti-Static Equipment
As plastic film moves through rollers, it can build up static electricity. This can cause problems like dust buildup, sticking, and even sparks, especially in dry environments.
Anti-static bars and brushes safely discharge this static electricity. They help protect workers, reduce dust on the film, and improve overall safety. We stock a full range of anti-static equipment to meet your line’s needs.
6. Corona Treaters
If you need to print or laminate your film, you’ll likely need a corona treater. This tool changes the surface of the film so that inks and adhesives stick better.
Corona treaters improve print clarity, bonding strength, and product durability. We supply compact and reliable corona treaters that are easy to operate and maintain.
7. Slitters and Rewinders
After the film is processed, you may need to cut it into smaller rolls or rewind it for packaging. Slitters and rewinders help you do this quickly and cleanly.
These tools allow for custom roll widths, easy quality checks, and better roll handling. Swallow Machinery offers slitting and rewinding equipment that is precise, fast, and safe to use.
8. Spare Parts and Accessories
Having the right spare parts on hand helps reduce downtime and keep your machines running efficiently. This includes parts like blades, bearings, seals, tensioners, and more.
Swallow Machinery stocks a wide variety of accessories and replacement parts. If you need something specific, we can supply it quickly to keep your production on track.
Final Thoughts
Blown film handling is a critical part of your production line. The right tools make the process more efficient, reduce waste, and lead to higher-quality film. From web guiding systems to anti-static bars and tension control, each tool plays a vital role in keeping your production smooth and successful.
