The Haitel HTL-280B/280E/350/450/550 series is a family of automatic pillow (flow) wrapping machines built for food factories, exporters, and contract manufacturers that need reliable, high-speed flexible packaging for regular-shaped products. Driven by a servo motor with flexible bag-length cutting, the machine lets operators change product sizes without re-adjusting the unloading mechanism — saving both time and packaging film.

(see product catalog, corresponding section)

The HTL-280 platform is engineered for versatility. It handles biscuits, egg pies, bread, chocolate, candy, instant noodles, moon cakes, as well as hardware, daily consumables, industrial parts, paper boxes, and trays. Where the catalog provides full technical parameters, the HTL-280B model is listed below; the 280E/350/450/550 variants share the same platform and are offered to cover different widths and throughput needs. For exact specifications of each variant, contact Haitel sales for confirmation.

Why Choose It

1. Servo-driven flexible bag length — Bag length is cut flexibly by a servo motor, so operators do not need to re-adjust the unloading work. This saves changeover time and reduces film waste.
2. Human–machine interface (HMI) — Convenient and quick parameter setting through an intuitive operator panel, shortening training time for new staff.
3. Self-diagnosis failure function — The machine displays faults clearly, helping maintenance teams identify and resolve issues fast and reducing unplanned downtime.
4. High-sensitivity optical color-mark tracking — Digital input of the cut position makes sealing and cutting more accurate, ensuring clean, consistent packages even on printed film.
5. Separate PID temperature control — Independent temperature control for each sealing bar suits various packing materials (OPP, CPP, PE, laminates, etc.) and stabilizes seal quality.
6. Selected-position stop, no film waste — The machine can stop in a selected position without sticking to the knife and without wasting packing film, protecting both product and consumable.
7. Simple, reliable drive system — The straightforward driving system is reliable in continuous operation and convenient to maintain, lowering lifetime service cost.
8. Software-based control — All controls are achieved by software, making function adjustment and future upgrading convenient as your product range evolves.

Typical Application Scenarios

• Bakery & snack lines — Pillow-pack biscuits, egg pies, bread, and moon cakes at line speed with printed-film registration.
• Confectionery — Chocolate bars, count-line candy, and regular-piece confectionery in tight, hygienic wraps.
• Instant noodles & convenience food — Single-serve and multi-pack flow wrapping for export and retail.
• Non-food contract packing — Hardware items, daily consumables, industrial parts, paper boxes, and trays where a clean protective pillow pack is required.
• Seasonal & promotional runs — Quick changeovers between product sizes thanks to flexible bag-length cutting and HMI presets.

Customer FAQs

1. What product sizes can the HTL-280B handle? The machine accepts products up to 140 mm bag width, 60 mm product height, and 50–500 mm bag length, with film width up to 280 mm. For the wider 280E/350/450/550 variants, contact Haitel sales for confirmation.

2. Do I need to re-adjust the machine when I change bag length? No. The servo motor enables flexible bag-length cutting, so operators do not need to adjust the unloading work when changing product length — a major time saver during changeovers.

3. Can it work with printed film so the design stays aligned? Yes. High-sensitivity optical color-mark tracking with digital cut-position input keeps sealing and cutting accurate, keeping printed graphics correctly registered.

4. What packaging materials are supported? Separate PID temperature control makes the machine suitable for various packing materials. Confirm the specific film grade for your product with Haitel sales for confirmation.

5. What power supply is required? The HTL-280B runs on 220 V / 50 Hz with 3 kW power. Verify your local supply and any variant-specific requirements with Haitel sales for confirmation.

6. Is it difficult to operate and maintain? The HMI makes parameter setting quick and convenient, the self-diagnosis function displays faults clearly, and the simple driving system is reliable and easy to maintain — minimizing training and service effort.

7. Can I add date coding or gas flushing later? Yes. A code printer and air (gas-flush) device are available as optional add-ons, so the machine can be upgraded as your requirements grow.

8. How do I choose between the 280B, 280E, 350, 450, and 550? Selection depends on your required film width, product dimensions, and throughput. The catalog details the HTL-280B; for the other variants' exact specs and a recommendation, contact Haitel sales for confirmation.

Conclusion

The Haitel HTL-280B/280E/350/450/550 multi-function automatic pillow packing machine combines servo-driven flexibility, accurate color-mark tracking, and software-based control into one dependable platform — ideal for food factories, exporters, and contract packers that demand fast changeovers and clean, consistent wraps.
