Leafy Greens (Romaine, Kangkung, Bok Choy) — FW-450B Bottom-Reel Box-Motion Flow Wrapper
Why standard wrappers damage leafy greens: Top-reel machines push loose leaves across metal plates, causing bruising and stem jams. Our FW-450B carries vegetables directly on the bottom film web.

Frequently Asked Engineering Questions
How do you prevent hydroponic lettuce with root balls or water droplets from fogging inside the bag?
We pair 25–30μm double-sided BOPP Anti-Fog film with an adjustable mechanical micro-pin perforator on the FW-450B. This balances moisture vapor transmission in 2–8°C supermarket chillers without dehydrating the leaves.
Can one FW-450B wrap both small 100g herb bags and 400g Romaine bunches?
Yes. The adjustable SUS304 bag former changes width in under 2 minutes without tools, and the dual Omron optical sensors automatically adjust cut length to each bunch.
