PVC blown film extrusion line
BG Plast designs and manufactures PVC blown film extrusion lines dedicated to the industrial production of technical and packaging films, developed in partnership with Robel do Brasil, one of the world’s leading specialists in PVC blown film extrusion technologies.
This collaboration combines BG Plast’s experience as a manufacturer of extrusion and calendering systems for plastics with Robel’s specific expertise in PVC processing, with the aim of offering the market complete, reliable and high-performance solutions.
The PVC Blown Film lines are designed to deliver bubble stability, thickness control and uniform film quality, even in particularly sensitive applications such as food packaging. The engineering approach focuses on optimizing the PVC extrusion process, from raw material selection to the final plant configuration.
Applications of PVC blown film extrusion lines
PVC blown film extrusion lines are found in various industrial sectors, particularly in flexible and technical packaging. The systems are suitable for the production of:
- PVC cling film for food packaging
- Semi-rigid and rigid PVC films
- Twist and rigid/twist films
- Heat-shrinkable films (soft shrink)
- Rigid shrink sleeves and labels
- Single- and multi-layer films, including in a double-bubble configuration.
Thanks to the high precision of the extrusion process and the accurate control of production parameters, the lines enable the production of 100% non-toxic films suitable for food contact, meeting the most stringent regulatory requirements. The solutions are suitable for both standard production and high-throughput systems for large volumes.
Technical specifications of PVC blown film extrusion lines
The BG Plast – Robel PVC Blown Film extrusion machines are advanced technological solutions designed to maximize efficiency, operational safety and the quality of the final product. Key technical features include:
- Next-generation extrusion towers, completely redesigned for more practical and safer use
- Increased tower height to provide a more stable, precise and uniform bubble
- Fully automatic calibration cage with motorized up/down movement
- Automatic, self-centering “Iris” system with motorized opening and closing
- Automatic bubble guidance systems and self-centering collapse tables
- New extruders, heads and winders optimized for PVC processing
- Advanced PLC software with precise temperature control.
The lines allow processing of thicknesses ranging from 0.006 to 0.300 mm and widths up to 1,500 mm, with production rates reaching 130 kg/h, up to 250 kg/h in high-end versions.Double Bubble configurations are also available for shrink film and sleeves, with high stretch ratios in both the longitudinal and transverse directions.
