Kraft Liner Board Prone to Edge Dust? CHM Double-Knife Cutting Machine Solves It Perfectly

In the paper converting industry, kraft liner board continues to maintain strong market demand and is widely used in carton packaging, premium packaging boxes, corrugated packaging, and paper bags. However, due to its high basis weight and strong fiber structure, the cutting quality directly affects the final product quality, making it a critical challenge that cannot be ignored.

Kraft liner board has strong fiber bonding, making it difficult to cut cleanly without edge tearing or burrs.

Improper cutting often generates paper dust and fiber fragments, affecting both cleanliness and downstream printing quality.

Heavy paper rolls tend to have inconsistent tension during unwinding, leading to deviation and uneven cutting.

High-end packaging paper requires:

Any defect will directly affect printing and packaging appearance.

The machine adopts a double-knife rotary cutting structure, ensuring stable and continuous cutting performance even for thick kraft paper. It delivers:

Equipped with automatic tension control and web guiding systems, the machine ensures stable paper feeding, effectively preventing deviation and improving cutting consistency.

To meet high-end packaging requirements, the machine can be equipped with a vacuum system to:

After high-speed cutting, the finished sheets are:

This CHM-SGT1700 Double-Knife Cutting Machine is processing 300gsm kraft liner board rolls with a diameter of 1245mm. Two rolls are being processed simultaneously. Equipped with a high-precision double rotary knife system, the CHM-SGT1700 synchronizes perfectly with the paper feeding speed. Even when handling large paper rolls with a diameter of 1245mm, the machine operates smoothly without vibration, deviation, or interruption. After high-speed cutting, the finished sheets are neatly stacked into standard “tofu block” piles. The sheets are free from bright spots, paper dust, and pressure marks, fully meeting the requirements for direct printing.

As a machine specifically designed for heavy paper applications, the CHM-SGT1700 Double-Knife Cutting Machine supports paper weights ranging from 200 to 1000 GSM, making it suitable for processing everything from standard heavy cardboard to specialty paperboard.

In addition, CHM offers double-knife cutting machines in different working widths, including 1400mm, 1700mm, and 1900mm, providing flexible solutions for both small-batch customized production and large-scale manufacturing. Whatever your workshop layout or production requirements, there is a configuration to match your needs.
