HF-400S/500S

High-speed continuous side-seal model, featuring servo control + reciprocating cross-sealing technology, designed for efficient heat shrink packaging.

Easily integrates with production lines, delivering stable operation and high efficiency.

Suitable for high-speed heat shrink packaging applications such as printed products, stationery, small bundled commodities, food, small daily chemical items, and electronic accessories.


Servo Sealing: Combines side-seal and reciprocating cross-sealing technologies for continuous, uninterrupted sealing. Driven by a servo motor, ensuring high-speed operation without shifting or slipping.

High-Speed Mass Production: Packaging speed of 60–120 packages per minute, suitable for high-volume production and significantly improving line efficiency.

Flexible Feeding: Optional feeding systems available to meet various needs; the conveyor easily connects to existing production lines, facilitating convenient retrofitting and installation.

Dual Conveyor Options: The push-finger conveyor is suitable for printed products and can be equipped with an automatic paper feeder; the guide-rail pusher conveyor is ideal for combination packaging and supports customization.

Intelligent Touchscreen: User-friendly large touchscreen interface for simple operation. Parameters can be stored and recalled, eliminating the need for repeated setup and making it easy for new operators to use.

Vertical Seal Cutting: Equipped with a four-column vertical drive system, the sealing blade moves up and down smoothly and powerfully, ensuring a precisely centered seal line. Effectively solves wrinkling issues when packaging tall-profile products.

Airflow intensity and conveyor speed are controlled and adjusted via inverters, allowing adaptation to different products for more even and consistent shrink results.

Utilizes a bottom-mounted circulating fan combined with an open-accessible structure design. The air outlet directions at the bottom and sides are adjustable, allowing air and heat to fully circulate within the chamber. This results in fast heating, high thermal efficiency, and improved energy savings.

Simple operation with automatic temperature control. Temperature accuracy can reach ±1°C, ensuring stable and reliable temperature control for consistent shrink quality.
