The GH‑6030CY+SF‑2050 Fully Automatic Linear Vertical Sleeve Sealing, Cutting, and Shrinking Machine is an integrated, straight-through system that combines a vertical sleeve sealing and cutting unit with a hot-air shrinking tunnel on a single linear production line. It is specifically designed for cylindrical and ring-shaped upright workpieces. Materials are conveyed unidirectionally along a straight track, sequentially completing the entire process—including feeding, vertical film application, sealing and cutting, and hot-air shrink wrapping—without the need for turns or detours, facilitating seamless integration with upstream and downstream production lines. The entire machine features a high-temperature-resistant metal chain conveyor structure compatible with POF heat-shrink film. It is suitable for the batch heat-shrink packaging of industrial components with high surface protection requirements. After packaging, the film fits snugly and closely around the workpieces, providing dust and moisture protection as well as surface protection, and facilitating storage and transportation.
