Fully-auto Sleeve Sealer & Shrink Tunnel （Integral Type)

Key Features:
Compatible with both single-item and tray-based dual-mode packaging: No tooling changes are required; single-item independent packaging and multi-item tray-based combination packaging can be freely switched to adapt to diverse packaging needs. No disassembly or adjustment is required during production changes.

Inductive Precision Film Feeding Structure: Relying on photoelectric sensors to match product size and output the corresponding film length, it eliminates excess film pulling and waste, significantly reducing consumable losses and saving packaging material costs.

Three-section anti-stick sealing blade assembly: A dedicated three-piece sealing blade design; the blade body is high-temperature resistant and non-stick to the film, ensuring a continuous and tight seal that is not prone to cracking. Even during extended mass production, issues such as seal breakage and scorched edges will not occur.

Integrated electromechanical and pneumatic intelligent control system: Equipped with a Siemens PLC and a human-machine interface touchscreen, the entire machine's mechanical, electrical, and pneumatic modules work in tandem. Parameters can be stored and retrieved with a single click, allowing for quick operation even for beginners.

Medium-speed stepless conveyor system: The main unit and tunnel speed are synchronously adjustable from 0 to 15m, suitable for various medium-capacity production lines. It operates without jamming or material accumulation, ensuring stable operation for 24 hours continuously.

Constant-temperature circulating hot air shrink tunnel: Independent and precise temperature control combined with a full-area circulating fan ensures uniform heating of the POF film, resulting in a tight seal against the product after forming. It is dustproof, moisture-proof, and protected against scratches and impacts during transportation. The entire machine is equipped with overload and jamming automatic shutdown protection. It uses a full set of imported core components from Siemens, Schneider Electric, and Autonics, ensuring a low failure rate and convenient global parts sourcing.

Applications: Widely compatible with automated wrapping of various standardized boxes, bottles, food gift boxes with paper trays, daily chemical sets, small hardware, electronic products, and beverage assemblies. Suitable for medium-capacity production lines in food processing plants, daily chemical workshops, small beverage production lines, and cultural and creative gift factories, catering to both single-item retail packaging and multi-item group shipping packaging needs.
