VFFS Baggers with Ultrasonic Sealing


Our X-Series VFFS Baggers with Ultrasonic sealing help improve OEE by creating an airtight seal, which significantly reduces leakers and rejects, and offers savings on film, material, and labor. This cold sealing technology also provides energy savings and other benefits, and is ideal for various markets, including cheese, confectionery, leafy produce, liquids, powders, and seafood.

Ultrasonic cross seal and back seal options are available on several Triangle VFFS Baggers. And, we offer the flexibility to easily switch between Ultrasonic cross seal and traditional heat seal on the same bagging machine!
