Automatic Corner Sealing Machine | Box Corner Taping Equipment
SunAura automatic corner sealing machines provide four-corner tape sealing for L-shaped folded cartons, creating premium gift-box packaging. Available in three models: JS-50 (semi-auto, 8-12 BPM), JS-100A (full-auto, 20m/min), and FCCS-1200 (high-speed, 12-18 BPM). All models feature 304 stainless steel construction, CE certification, and adjustable carton guides for various box sizes.
Product Description
SunAura offers a complete range of automatic corner sealing machines for premium packaging applications. The JS-50 is a semi-automatic model where the operator folds carton flaps into L-shape and the machine applies tape to all four corners. The JS-100A is a fully automatic model that folds flaps and applies corner tape automatically. The FCCS-1200 is a high-speed servo-driven model with PLC control for large-volume production.
All models apply tape to all four top corners of L-shaped cartons simultaneously, creating a professional gift-box appearance that enhances product presentation. This corner sealing method provides superior package integrity compared to standard top-only sealing, preventing carton opening during shipping and handling.

Frequently Asked Questions
What is the difference between the three corner sealing models?
The JS-50 is semi-automatic (manual flap folding, 8-12 BPM), the JS-100A is fully automatic (auto flap folding, 20m/min), and the FCCS-1200 is a high-speed servo-driven model with PLC control (12-18 BPM, handles large cartons up to 800x650x650mm).
What is corner sealing and why is it used?
Corner sealing applies tape to all four top corners of L-shaped folded cartons, creating a premium gift-box appearance. It provides superior structural integrity compared to standard top-only sealing and is used for high-end product packaging where presentation matters.
Which model should I choose for my production volume?
For low to medium volumes (100-500 boxes/day), the JS-50 is ideal. For medium volumes (500-2000 boxes/day), the JS-100A provides full automation. For high volumes (2000+ boxes/day) with large cartons, the FCCS-1200 with servo-driven system and PLC control is recommended.
Do all models require compressed air?
The JS-50 does not require compressed air, making it easy to install anywhere. The JS-100A and FCCS-1200 require 0.4-0.6MPa compressed air for their automatic folding mechanisms.
What tape widths are supported?
The JS-50 and JS-100A use 48mm tape. The FCCS-1200 supports 48mm, 60mm, and 72mm tape widths, providing flexibility for different package weights and sealing strength requirements.
Are the machines CE certified?
Yes, all three models are CE certified and meet European safety standards. They include emergency stop buttons, safety interlocks, and operator protection features for safe operation.
Can the machines handle different carton sizes?
Yes, all models feature adjustable carton guides for different sizes. The JS-50 handles 150-400mm, JS-100A handles 200-500mm, and FCCS-1200 handles 300-800mm carton lengths, covering a wide range of packaging box sizes.
