Cardboard is a well-known material in the packaging industry, famous for its lightweight structure and flexibility. Made primarily from paper pulp, cardboard is strong, sustainable, and suitable for various shipping and retail packaging applications.
In this blog, we’ll explore what cardboard is made of, how it’s manufactured, and why it remains an ideal solution for businesses seeking sustainable, affordable, and customizable packaging.
What Is Cardboard Made of?
Cardboard is composed of paper pulp, which is sourced by processing natural plant and wood fibers. This fibrous material is refined to form durable sheets used in packaging. It’s important to differentiate between general cardboard and corrugated cardboard. While cardboard refers to thick paper-based material, corrugated cardboard features a fluted inner layer sandwiched between two linerboards, enhancing durability and shock absorption.
To understand better, cardboard comes in several forms, each with unique properties for different uses:
- Corrugated Cardboard: Known for its fluted inner layer, this type is ideal for shipping and transporting goods.
- Paperboard: A thinner, single-layer material commonly used for retail packaging like cereal boxes.
- Chipboard: Made from recycled paper, chipboard is dense and often used for backing or folding cartons.
Understanding these differences will help businesses choose the right packaging material based on durability, cost, and sustainability.
How Is Cardboard Manufactured?
The process of manufacturing cardboard involves several steps, and they are outlined below:
- Pulping: The initial step involves creating wood pulp from trees. Chopped wood is mixed with water and chemicals to remove impurities and break down the fibers.
- Cleaning: The pulp undergoes screening and cleaning to eliminate any remaining impurities, preparing it for the subsequent stages.
- Bleaching: If necessary, the pulp may be bleached to achieve a consistent white color, removing any residual hues.
- Forming: Using a machine like the Fourdrinier machine, the pulp is shaped into flat sheets. It’s poured onto a flat surface and drained, forming a layer of pulp.
- Pressing: The pulp sheets are then pressed between large rollers to create a smoother surface.
- Cutting and Shaping: Finally, the cardboard sheets are cut and shaped into various products such as boxes, containers, or other items.
Why Choose Cardboard for Packaging?
In an era of growing environmental awareness, businesses are seeking packaging solutions that are both functional and planet-friendly. Cardboard packaging delivers on both fronts—offering strong protection for products and reducing the ecological footprint.
Its biodegradable, recyclable nature aligns with the values of eco-conscious consumers. Most importantly, cardboard offers a unique blend of practicality and customization, such as:
- Customizable: It can be printed, embossed, or cut into various shapes to match brand identity.
- Cost-effective: Economical for both large-scale and small-batch packaging.
- Brandable: Enhances unboxing experiences and increases customer engagement.
Overall, choosing cardboard aligns with both customer expectations and eco-conscious business strategies.
