Features
  • Intelligent Control
    The new production line is equipped with IoT sensors for real-time monitoring of humidity, temperature, and tension.
  • Energy-Saving Design
    Heat pump technology replaces gas drying, reducing energy consumption by up to 30%.
  • Pre-Printing Integration
    The 7-layer corrugated cardboard production line can be integrated with high-definition printing to achieve a one-stop process from board production to finished products.
  • Tailored Configurations
    Production line setups can be customized based on product weight, transportation environment, and budget. For example, a 5- corrugated cardboard production line can be equipped with a moisture-proof coating machine or ground logistics system for enhanced performance.

Corrugated Cardboard Converting & Carton Box Making Machines

Corrugated production lines generally use electric heating, steam heating, liquefied gas heating, or thermal oil heating.

Food and beverage packaging requires corrugated board with moisture resistance and eco-friendly features. A 3-layer or 5-layer corrugated board is usually sufficient, with production speeds of 120–250 m/min.

Electronic products require strong protection during transportation to prevent physical damage. A 3-layer or 5-layer corrugated board with E-flute is commonly used to balance strength and cost efficiency.

Large appliances such as refrigerators and washing machines require packaging with high compression strength and shock resistance. A 7-layer corrugated board is typically recommended for this application.

For lightweight express packaging, a 3-layer corrugated board production line is most suitable. It provides short changeover times, low energy consumption, reduced material usage, and high production speeds of 120–250 m/min, supporting large-volume orders.
