Automatic Rotary ROPP Cap Sealing Machine

The Automatic Rotary ROPP Cap Sealing Machine from USA Pack Machines LLC provides a high-efficiency solution for sealing ROPP (Roll-On Pilfer Proof) caps on bottles, combining speed, precision, and reliability. Designed for industries such as pharmaceuticals, cosmetics, food and beverages, and chemicals, this machine ensures secure, tamper-evident closures while maintaining consistent product quality across high-volume production lines.

Built on a robust main structure, the machine integrates a product transmission belt with an adjustable guide that seamlessly transports bottles through the sealing station. The in-feed screw and star plate position each bottle accurately, ensuring uniform sealing results. Simultaneously, the sealing heads rotate and apply precise torque to the ROPP caps, delivering a perfect seal every time. The vibratory bowl and cap delivery chute guarantee a smooth and continuous supply of caps, preventing interruptions in production and enhancing operational efficiency.

With an adjustable product height screw, the machine accommodates bottles of various sizes and shapes, providing versatility and flexibility for diverse packaging requirements. The optional safety acrylic cover ensures operator protection while allowing clear visibility of the sealing process. Additionally, the machine features an electrical panel, sensors, motor, and AC drive, offering precise control, real-time monitoring, and consistent performance throughout the operation.
