Product Description

Why Choose the 850C Wide Side Sealer?

Massive Width Capacity: With an 850mm sealing cutter, this machine breaks the size barrier. It is perfect for wide, flat products that standard 450/550 machines cannot handle.
Servo Stability: Moving a large 850mm blade requires precision. The KS Custom Servo Drive ensures the sealing action is smooth, fast, and consistent, avoiding the "slamming" vibration often found in pneumatic large-format machines.
Unlimited Length: Like all side sealers, the longitudinal seal is continuous. You can pack a 50cm wide product whether it is 1 meter long or 5 meters long.
Smart Operation: Forget manual hand-cranking. The Touchscreen Electric Height Adjustment allows you to set the sealing line height automatically, speeding up product changeovers.

Application Scenarios

Furniture & Home Decor: Cabinet doors, shelving boards, large photo frames, mirrors.
Household Goods: Ironing boards, drying racks, large storage boxes.
Electronics: Large flat-screen TV boxes, computer monitors.
Textiles: Wide rolls of fabric, yoga mats, bedding comforters.

Key Features & Technical Highlights

Safety First: Large openings can be dangerous. We utilize German SICK Sensors to detect any obstruction (like a hand or product) under the knife, instantly stopping the cut to prevent injury.
Premium Sealing: The alloy steel knife is coated with DuPont Teflon, ensuring that POF film never sticks to the blade, even during long production runs.
Reliable Components: The electrical cabinet is a fortress of quality, featuring Omron (Japan) relays and thermostats, Schneider/Chint breakers, and Banner (USA) photo eyes.
Adjustable Speed: The belt speed and packing rate (1-15 pcs/min) are fully adjustable via the touchscreen to match your upstream production flow.
