Corrugated boxes are an essential packaging solution for industries worldwide due to their strength, durability, and eco-friendliness. The manufacturing process involves multiple stages, ensuring that each box meets high-quality standards and provides maximum protection.
The process begins with selecting high-quality kraft paper, which is strong, lightweight, and recyclable. The paper is sourced in large rolls and serves as the foundation of corrugated box production.
The kraft paper is passed through heated rollers, which create a fluted (wave-like) structure.
This fluted paper is then glued between two flat linerboards, forming a single-wall corrugated sheet.
Additional layers can be added to create double-wall or triple-wall corrugated sheets for extra strength.
Once the corrugated sheets are formed, they are cut and shaped according to the required box dimensions. This step is performed using precision die-cutting machines that ensure accuracy.
Custom designs, logos, product details, barcodes, and handling instructions are printed onto the boxes.
Advanced printing techniques like flexographic or digital printing are used for clear and durable prints.
