SZ801W Box Motion Packaging Machine
SZ801W
SZ801W Packaging Machine Typical Applications
- Bakery & Confectionery: bread loaves, tray-packed cakes, mooncakes.
- Frozen Food: dumplings, seafood, meat trays.
- Household & Non-food: disposable products, medical kits, hardware tools.
- Specialty Packaging: extra-wide pillow bags or laminated barrier films.
The SZ801W Box Motion Packaging Machine is a specialized horizontal flow wrapping system engineered for large-format products, tray-packed items, and applications requiring extra-wide films up to 900 mm. Unlike high-speed rotary sealers such as the SZ580, the SZ801W is optimized for packaging quality rather than sheer output speed, running steadily at 50 packs per minute.
Its defining feature is the box motion sealing system, which moves horizontally during the sealing process. This extended dwell time creates airtight, reliable seals even when using multi-layer laminated or aluminum-coated barrier films. As a result, products such as frozen dumplings, seafood trays, bread loaves, or medical kits are kept fresh, leak-proof, and protected throughout distribution.
The SZ801W also incorporates servo-driven film pulling and product feeding, ensuring precise alignment for bulky or irregular items. The wide infeed conveyor accommodates large trays, oversized bakery goods, or industrial components, minimizing misfeeds and reducing film waste.
In short, the SZ801W is not a speed-driven machine, but a reliability-focused solution for manufacturers who need to balance seal integrity, packaging flexibility, and film width adaptability in demanding production environments.

Competitive Advantage of SZ801W Box Motion Flow Wrapper
Many buyers face recurring problems when evaluating flow wrappers: leaking seals, limited film width, unstable feeding of heavy products, and poor ROI from frequent rework. The SZ801W was specifically designed to overcome these frustrations and to outperform conventional rotary machines.
- Seal Integrity vs. Competitor Leakage: Standard rotary flow wrappers often struggle with laminated or high-barrier films, resulting in weak seals and product spoilage. The SZ801W’s box motion sealing system applies stronger pressure and longer dwell time, guaranteeing airtight, consistent seals that reduce complaints, returns, and wasted inventory.
- Film Width Flexibility vs. Market Limitations: Most machines in this class cap film widths at 500–600 mm, making them unsuitable for oversized or tray-packed products. The SZ801W supports film widths up to 900 mm, enabling factories to expand their product portfolio without costly customization.
- Stable Feeding vs. Product Misalignment: Heavy, soft, or irregular products often shift during packaging on competitor machines, causing misaligned seals and material waste. The SZ801W uses a servo-controlled wide infeed conveyor that maintains stable product positioning, ensuring consistent pack quality with minimal rejects.
- True ROI vs. Superficial Speed: While competitors highlight “higher packs per minute,” for bulky items speed often translates into more rework and downtime. The SZ801W prioritizes efficiency through waste reduction, reliable sealing, and fewer stoppages, delivering a stronger return on investment for factories packaging larger goods.
👉 With its ability to solve seal failures, film restrictions, unstable feeding, and ROI concerns, the SZ801W offers tangible business value that many competitors cannot match.
