Corrugated boxes are one of the most widely used materials across various industries for packaging solutions. In industries such as shipping, retail, and storage, these boxes offer durability, cost-effectiveness, and sustainability. But what exactly goes into making a corrugated box?

If you’re searching for a Corrugated Box Manufacturer in Lagos or looking to understand how carton packaging companies operate, this article provides an in-depth look into the raw materials used in corrugated box production.

What Are Corrugated Boxes Made Of?

The primary raw material for manufacturing corrugated boxes in Nigeria is kraft paper, which is derived from wood pulp. However, the process involves multiple materials that contribute to the strength and functionality of the final product.

1. Kraft Paper (Virgin & Recycled)

Kraft paper is the main component of corrugated boxes. It is produced using the kraft process, which involves chemically treating wood fibres to create a strong, durable material. Carton box manufacturers in Nigeria often use a combination of:

Virgin Kraft Paper – Made from fresh wood fibres, offering higher strength and durability.

Recycled Kraft Paper – A more eco-friendly option made from reused paper products while maintaining structural integrity.

2. Fluting Medium

The fluted (wavy) layer inside a corrugated box is what gives it its cushioning properties. This layer provides shock absorption, making corrugated boxes ideal for packaging fragile or valuable goods. The fluting is usually made from semi-chemical pulp or recycled paper.

3. Adhesives (Starch-Based Glue)

To bond the different layers of a corrugated box together, starch-based adhesives are used. This glue is made from natural sources like maize, wheat, or tapioca, ensuring a strong yet biodegradable adhesive that enhances sustainability.

4. Ink and Coatings

For branding and printing purposes, carton manufacturers in Lagos use specialized inks to print logos, handling instructions, and product information on the boxes. Water-based and soy-based inks are commonly used due to their eco-friendliness. Some manufacturers also apply protective coatings to increase water and oil resistance.

In conclusion, Corrugated boxes remain an essential packaging solution across various industries due to their strength, durability, and sustainability. The key materials used: kraft paper, fluting medium, starch-based adhesives, and specialized inks/coatings work together to create a reliable, and cost-effective packaging for businesses.
