What types of corrugated board can your production line manufacture?

The available production lines can produce a wide range of single-face and multi-layer corrugated boards, including A-, B-, C-, E-, and F-flutes, as well as 3-ply, 5-ply, and 7-ply structures. Different flute heights and pitches can be configured to meet applications from lightweight packaging to heavy-duty transport.

Can the corrugated board production line support flexible switching between different board specifications?

Yes. The equipment allows one-touch adjustment of board width (typically 1400-2500 mm) and layer parameters, enabling continuous production of various sizes and ply counts without long downtime for mechanical changeovers.

Can the production line switch between different flute combinations or board layers on the same line?

Certain models support flexible switching among 3-ply, 5-ply, and 7-ply board structures and multiple flute combinations on a single line, allowing fast order changes and significantly reducing manual setup.

Does the equipment support special flutes, single-face board, or double-wall structures?

Yes. In addition to standard 3-layer boards, our lines can produce single-face board, double-wall combinations (such as BC, BE), and other composite structures, supporting the development of specialty packaging with enhanced strength and cushioning.

How strong is the corrugated board produced by QH-PACK equipment?

QH-PACK lines use high-precision corrugating rolls and an intelligent tension-control system to ensure excellent bonding between layers. The resulting board delivers superior compression strength, load-bearing performance, and cushioning, fully meeting packaging standards for logistics, e-commerce, home appliances, and heavy-duty industries.

Can the equipment develop special structures or non-standard boards for customized box designs?

Absolutely. The equipment can adjust flute profiles, liner/medium combinations, and bonding methods according to order requirements. It also supports slotting, punching, and window-cutting processes to help customers develop corner-protectors, inserts, gift-box components, and other functional structures.

Can the corrugated board line be customized for non-standard widths or special paper requirements?

Yes. QH-PACK offers non-standard customization based on plant layout, raw paper width, and special application needs, including ultra-wide formats, high basis-weight materials, and specialty paper types.

How stable and precise is the production line?

All main units, drive components, and control systems use high-quality imported parts. With automatic temperature, tension, and alignment control, the line produces corrugated boards with uniform thickness, strong adhesion, and extremely low deviation.

How does the equipment perform in terms of energy-saving and environmental protection?

The production line features high-efficiency motors, multiple heating-method options, and an automatic waste collection system to reduce energy consumption and material waste, supporting greener, more economical production.
