Introduction

In today's world of online shopping, paper board packaging has become the norm for delivering products to our doorstep. Whether it's a small item or a large package, paper board is a versatile and widely used packaging material. But not all paper board is created equal. There are various grades of paper board available in the market, and each grade has its own unique properties and applications. In this article, we will explore the different grades of paper board, their strengths and weaknesses, and how they can be effectively used in packaging design.

The Importance of Paper Board Packaging

Paper board packaging is more than just a means to protect and deliver products. It plays a crucial role in creating a positive brand and product impression on consumers. It is often the first point of contact between the product and the shopper, influencing their purchasing decisions. But when it comes to designing with paper board, there are many factors to consider. Understanding the different grades of paper board is essential to ensure that the packaging meets the specific requirements of the product and provides the desired functionality.

Understanding Paper Board Grades

Solid Bleach Sulfate (SBS)

Solid Bleach Sulfate (SBS) is a premium grade of paper board made from virgin hardwood fibers. It is known for its surface consistency and excellent printability. SBS is often coated with a mineral or synthetic coating on both sides, making it suitable for direct food contact. It is the grade of choice for applications that require high-quality printing, such as frozen food packaging. However, SBS is also the most expensive grade of paper board.

Solid Unbleached Sulfate (SUS)

Solid Unbleached Sulfate (SUS) is another popular grade of paper board. It is made from virgin hardwood fibers and has natural resistance to moisture. SUS is often used in applications that require high strength, such as beverage holders. It is less expensive than SBS and offers good printability and foldability.

Unbleached Kraft (UK)

Unbleached Kraft (UK) is a natural grade of paper board. It is made from a blend of softwood fibers, such as pine trees, and may also contain recycled fibers. UK is known for its high strength and lower cost compared to SBS and SUS. However, it is not suitable for applications that require crisp and bright printability.

Coated Recycled Board (CRB)

Coated Recycled Board (CRB) is a versatile grade of paper board. It is made from 100% recycled content and is commonly used for lightweight items like cereal bags or snacks. CRB offers a lower cost alternative for non-food contact packaging needs.

Uncoated Recycled Board (URB)

Uncoated Recycled Board (URB) is the least expensive grade of paper board. It is often used for applications that are not in plain view, such as set-up boxes or dividers. URB provides high value for cost-conscious packaging requirements.

Folding Box Board (FBB)

Folding Box Board (FBB) is a multiply grade of paper board. It combines the strength of mechanical pulp layers with the printability of chemical pulp layers. FBB is a versatile grade that can be used for a wide range of applications. It offers good usability and can be enhanced with premium coatings. Depending on the composition and coatings, FBB can be competitively priced with SBS or offer more economical options.

Comparing Strength, Printability, and Cost

When designing with paper board, it is important to consider factors such as strength, printability, and cost. SBS and SUS offer excellent printability and strength but come at a higher cost. UK provides high strength at a lower cost but lacks crisp printability. CRB and URB offer cost-effective options for specific packaging needs, while FBB combines strength and printability at competitive or more economical prices.

Applications and Uses of Different Paper Board Grades

Each grade of paper board has its own specific applications and uses. SBS is commonly found in frozen food packaging, while SUS is popular for beverage holders. UK is suitable for heavy-duty items and wet environments. CRB is ideal for lightweight items like cereal bags, and URB is often used for set-up boxes or dividers. FBB is a versatile grade that can be used in various applications.

Considerations for Designing with Paper Board

When designing packaging with paper board, it is essential to consider the specific requirements of the product, as well as factors such as cost, brand image, and functionality. Understanding the different grades of paper board and their strengths and weaknesses will help ensure the packaging meets these requirements.

Conclusion

Paper board packaging is an integral part of the product delivery process. Understanding the different grades of paper board and their properties is essential for designing effective and functional packaging. From SBS to FBB, each grade has its own unique strengths and applications. By considering factors such as strength, printability, and cost, packaging designers can make informed choices and create packaging solutions that meet the specific needs of their products.
