Introduction
Corrugated cardboard boxes are one of the most widely used packaging solutions due to their strength, lightweight nature, and customizability. From shipping containers to retail packaging, these boxes are designed in various shapes, structures, and styles to suit different applications.
If you’re new to packaging materials and box design, this guide will help you understand the different types of corrugated cardboard boxes, their structures, and how they are designed for various industries.
What is Corrugated Cardboard?
Corrugated cardboard is a durable, multi-layered material consisting of:
- Two outer linerboard layers for structure and protection.
- A fluted (wavy) middle layer that provides cushioning and strength.
This combination gives corrugated cardboard high impact resistance, making it ideal for protecting goods during transit.

2. Flat and Slim Boxes
- Used for pizza boxes, document storage, and electronic packaging.
- Designed to minimize space while offering protection.
3. Tall and Tube-Shaped Boxes
- Ideal for posters, rolled-up documents, and specialty packaging.
