FENGCHI Showcases GW-1450L Heavy-Duty Flute Laminator and FZ-1450 Flip Flop Stacker at China International Paper Packaging Expo 2026

FENGCHI Printing Machinery showcased its GW-1450L heavy-duty flute laminator and FZ-1450 flip flop stacker at China International Paper Packaging Expo 2026, highlighting advanced corrugated board laminating technology, reduced adhesive consumption, and servo-driven sheet handling. Designed for demanding packaging production environments, the two machines combine heavy-duty construction, stable high-speed operation, and precise control to help corrugated packaging manufacturers improve productivity and finished-board quality.

GW-1450L Heavy-Duty Flute Laminator: Built for Stable, High-Speed Production

The GW-1450L heavy-duty flute laminator was originally designed for a maximum speed of 22,000 sheets per hour. For practical production applications, FENGCHI limits its operating speed to 16,000 sheets per hour to prioritize stable operation and consistent laminating quality.

Laser-Engraved Anilox Roller for Adhesive Savings

The GW-1450L features a laser-engraved anilox roller that provides controlled adhesive application. When processing smooth-faced five-ply corrugated board, the system can reduce adhesive consumption by more than 30%, according to FENGCHI’s stated performance data.

Optimized adhesive application helps improve bonding consistency and contributes to greater finished-board rigidity, supporting the production of high-quality corrugated packaging.

Heavy-Duty Construction for Demanding Applications

To withstand the demands of continuous industrial production, the GW-1450L incorporates a double-bearing design and reinforced side panels. These structural features are intended to improve mechanical stability and support reliable operation under heavy workloads.

For packaging manufacturers processing thick corrugated board, robust machine construction is an important consideration when selecting a high-speed flute laminator.

Lead-Edge Feeding for Thick and Lightweight Corrugated Board

FENGCHI was an early innovator in applying a lead-edge feeding system to flute laminating machines. The design generates a strong airflow to support reliable sheet feeding, particularly when handling thick, heavy, or warp-prone corrugated board.

This feeding technology is suitable for demanding applications such as fruit crates made from five-ply or thicker corrugated board. It also enables the machine to process lightweight flute grades, including F-flute and G-flute.

By accommodating a broad range of board specifications, the GW-1450L offers greater production flexibility for corrugated packaging manufacturers serving different market segments.

FZ-1450 Flip Flop Stacker: Servo Control for Precise Sheet Handling

Complementing the GW-1450L flute laminator, the FZ-1450 flip flop stacker is designed to synchronize with the laminating machine at production speeds of up to 16,000 sheets per hour under suitable operating conditions.

Its lifting mechanism and servo-driven paper take-off system are designed to improve stacking stability, reduce mechanical wear, and protect delicate sheets during high-speed operation.

Linear Guide Lifting Mechanism for Long-Term Stability

The FZ-1450 uses a linear guide in the flipping roller’s lifting mechanism, a feature FENGCHI identifies as a first in China for this application.

Traditional lifting mechanisms using drop rods can develop clearance after prolonged use. This wear may cause imbalance and vibration, affecting stacking stability.

By adopting a linear guide, FENGCHI aims to deliver smoother lifting motion, reduce the impact of mechanical wear, and maintain reliable performance over extended production cycles.

Six Servo Motors for Intelligent Paper Take-Off

One of the FZ-1450’s key features is its six-servo-motor-driven paper take-off unit.

While conventional stackers often rely on standard motors and pneumatic cylinders to push sheets, the FZ-1450 uses servo motors controlled by programmed motion curves. The control system coordinates acceleration, movement, and pauses during the sheet-pushing process.

This precise motion control is particularly beneficial when handling thin paper and lightweight board, which can be vulnerable to bending, tearing, or warping during stacking.

By optimizing the sheet-handling process, the FZ-1450 helps manufacturers achieve more consistent stacking quality while maintaining high production efficiency.

An Integrated Flute Laminating and Stacking Solution

Combining the GW-1450L heavy-duty flute laminator with the FZ-1450 flip flop stacker creates a coordinated production solution for corrugated packaging plants.

Key benefits include:

• High-speed production: The machines can operate in synchronization at up to 16,000 sheets per hour under suitable production conditions.
• Reduced adhesive consumption: The GW-1450L’s laser-engraved anilox roller can reduce adhesive application by more than 30% on smooth-faced five-ply board.
• Broad material compatibility: Processing capabilities extend from thick, warp-prone corrugated board to lightweight F-flute and G-flute.
• Stable mechanical performance: Reinforced machine construction and a linear guide lifting mechanism support reliable operation.
• Gentle sheet handling: Six servo motors and programmed motion curves help reduce damage when stacking thinner materials.

For manufacturers evaluating a new flute laminator or upgrading an existing corrugated board production line, assessing the complete laminating and stacking process can help identify opportunities to improve throughput, material utilization, and finished-product consistency.
