PVC soft, rigid and foamed extrusion lines
PVC extrusion lines have always been among the most challenging applications in the field of thermoplastic extrusion machinery. Whether rigid PVC, plasticized (soft) PVC, or foamed PVC, this polymer demands extremely rigorous control at every stage of the process, from plant design through to the operational management of the line. It is precisely on this complexity that BG Plast has built, over the years, a unique asset of technical expertise, the result of direct experience, continuous experimentation and consolidated application know-how.
PVC is, in fact, a thermally sensitive material, with a narrow processing window and rheological behavior that imposes strict rules in the design of plastic extrusion systems. Neglecting even one of these aspects compromises the line’s efficiency, the quality of the finished product and the stability of the production process. BG Plast’s solutions are designed exactly to meet these needs, with reliable, high-performance, custom-designed PVC extrusion lines.
Applications of rigid, flexible, and foamed PVC
Thanks to the design flexibility of our PVC extrusion lines, we are able to supply highly specialized sectors and value-added niche applications. Key applications include:
- Non-toxic PVC film for food packaging, produced via bubble extrusion
- Rigid PVC film for credit cards, with thicknesses up to 250 microns
- Acrylic PVC sheets for aerospace applications, such as Airbus interiors
- Non-toxic plasticized PVC film for medical bags, with thicknesses up to 850 microns
- “Low-foam” expanded PVC sheets, with thicknesses ranging from 1 to 20 mm (greater thicknesses available upon request)
- Co-extruded expanded PVC sheets for technical and decorative applications
- Rigid PVC sheets for general-purpose use, with embossed, satin-finished or custom finishes.
In many of these fields, particularly in food packaging and the medical sector, the quality of the extruded material and the stability of the process are essential requirements, demanding systems designed to extremely rigorous and high standards.
Technical specifications of BG Plast’s PVC extrusion lines
The development of a rigid, soft or foamed PVC extrusion line requires a thorough understanding of the material’s behavior. For this reason, BG Plast designs each system by first analyzing the final product and its application specifications.
The single-screw extruders, extrusion heads and calendering or cooling systems are sized and configured to ensure accurate control of PVC extrusion temperatures, thereby preventing thermal degradation and maintaining stable processing even during extended production runs. In the case of expanded PVC extrusion, particular attention is paid to foam management, density control and the uniformity of the cellular structure.
Multi-calender extrusion lines allow for the production of sheets with consistent thicknesses, high-quality surfaces and customizable finishes, while co-extrusion configurations enable the combination of different materials and properties within the same product. Each system is designed to integrate seamlessly with haul-off, cutting, stacking or winding systems, depending on the customer’s production requirements.
PVC extrusion machine: expertise and industrial vision
BG Plast’s PVC extrusion lines are the result of an industrial vision that combines technical expertise, mechanical reliability and the ability to tackle complex applications. It is not simply a matter of supplying PVC extrusion machines, but of building custom-designed extrusion systems capable of delivering constant quality, reduced waste and long-term competitiveness.
