Packaging materials such as paperboard and cardboard are an integral part of everyday life. They are ubiquitous in industry, logistics, and among consumers. Although we often use these terms interchangeably, they actually refer to two distinct materials. In this article, we explain the key differences between paperboard and cardboard in terms of structure, applications, and manufacturing processes.
What is Paperboard?
Paperboard is a paper-based material with a higher grammage than traditional paper, typically above 160 g/m². It is characterized by a smooth surface, uniform structure, and good printability, making it ideal for aesthetic applications. Paperboard is commonly used for:
-
producing individual packaging (e.g., boxes for cosmetics or pharmaceuticals),
-
manufacturing office supplies (e.g., binders, folders),
-
creating promotional materials such as flyers or displays.
The main advantage of paperboard is its aesthetic appeal and the ease of customization. Due to its structure, it can be easily processed, allowing for precise shapes and fine details.
What is Cardboard?
Cardboard is a more durable paper-based material composed of one or more layers of paper. It is thicker and more resistant to mechanical damage than paperboard. There are several basic types of cardboard:
-
Corrugated cardboard – made of flat and wavy layers, providing rigidity and cushioning. It is mainly used for transport packaging.
-
Solid board – has a homogeneous structure and is used for producing more elegant packaging, such as boxes for alcohol or luxury goods.
Cardboard is used in:
-
the packaging industry (bulk packaging, shipping boxes),
-
furniture and decorative element production,
-
eco-friendly projects, such as plastic alternatives.
Paperboard vs. Cardboard
Grammage and thickness:
-
Paperboard has lower grammage and is thinner, making it more flexible.
-
Cardboard is thicker and stiffer, offering greater durability.
Structure:
-
Paperboard has a uniform structure.
-
Cardboard can be multi-layered, including corrugated layers.
Applications:
-
Paperboard is mainly used for individual and aesthetic packaging.
-
Cardboard is used where durability and protection are essential.
Manufacturing process:
The production of both paperboard and cardboard starts with the processing of pulp, but the finishing processes differ depending on the material. Paperboard goes through smoothing and calendering to achieve a uniform structure. Cardboard, on the other hand, requires the bonding of paper layers with adhesive, and in the case of corrugated cardboard – forming the wavy layer.
Summary
Although paperboard and cardboard are often treated as synonyms, they are two different materials with distinct properties and applications. Understanding these differences is crucial for selecting the appropriate packaging, especially in the context of industry, logistics, and environmental protection. The final choice depends on individual needs: whether the priority is aesthetics and lightness or durability and functionality.
