USF-550S Automatic carton sealing machine | 10-15 boxes/min

⚙️ Machine Overview

The USF-550S automatic carton sealing machine is designed for efficient top and bottom sealing of filled cartons in packaging lines. It supports box dimensions ranging from L200–550 mm, W120–500 mm, and H150–500 mm, allowing flexibility for various shipping formats. The system operates at a working speed of 10–15 boxes per minute, depending on carton size.

⚙️ Suitable Applications

This equipment is ideal for sealing cartons used in food processing, beverage production, electronics packaging, household goods distribution, e-commerce fulfillment, and industrial manufacturing. It is suitable for products packed in corrugated boxes such as bottled drinks, canned goods, appliances, spare parts, cosmetics, and consumer merchandise. Any operation requiring consistent and secure carton closure can benefit from this solution.

⚙️ Technical Operation

The sealing process uses adhesive tape with a width of 4.8–7.2 cm, ensuring strong and reliable closure of both the upper and lower flaps. Adjustable guides allow the machine to adapt to different carton widths and heights within the supported range. The automatic alignment mechanism keeps boxes centered during sealing for uniform results.

⚙️ Efficiency and Integration

With a capacity of up to 15 cartons per minute, the USF-550S maintains smooth workflow in medium and high-volume packing environments. The structure is designed for integration with carton erectors, filling systems, and conveyor lines. Consistent tape application and stable operation help reduce manual labor and improve overall packaging efficiency.
