About Paperboard
Paperboard, a versatile and sturdy material, is a type of thick paper known for its exceptional strength and durability. It is manufactured through a process involving layering and compressing pulp fibers. With its rigidity, it finds use in packaging applications like cartons, boxes, and displays for various consumer goods. Its thickness distinguishes it from regular paper, making it suitable for protecting delicate items during transportation. Paperboard is also eco-friendly, as it is often made from recyclable materials and can be recycled. Its customizable nature, printability, and eco-consciousness make it a preferred choice in sustainable packaging solutions.
Why is Paperboard used for Corrugated Box Manufacturing
Paperboard is commonly used for manufacturing corrugated boxes due to its structural and functional qualities that make it an ideal material for packaging. Here’s why paperboard is chosen for corrugated box manufacturing:
- Strength and Durability: Paperboard’s inherent strength and durability provide protection to the contents of the corrugated box. It can withstand the rigors of handling, transportation, and storage, ensuring that the items inside are well-protected.
- Layering Capability: Corrugated boxes are composed of multiple layers, including an inner fluted layer and outer liner layers. Paperboard serves as the outer liner layers, offering additional reinforcement and stability to the box’s structure.
- Printability: Paperboard provides a smooth surface that is highly receptive to printing, branding, and graphics. This allows for attractive packaging designs and branding elements on the outer surface of the corrugated box.
- Customizability: Paperboard can be easily cut, folded, and shaped into various box designs to suit specific packaging needs. It allows for the creation of boxes in different sizes and styles to accommodate various products.
- Environmental Considerations: Many paperboards used in corrugated boxes are made from recycled materials and are themselves recyclable. This aligns with eco-friendly packaging practices and sustainability goals.
- Cost-Effectiveness: Paperboard is generally more affordable compared to other packaging materials, making corrugated boxes a cost-effective option for shipping and storage.
- Cushioning and Insulation: The fluted layer of corrugated boxes provides cushioning and insulation, protecting the contents from impact and temperature variations. The combination of paperboard and fluting ensures a balance between strength and shock absorption.
Types of Paperboard Used in Corrugated Box
Various types of paperboard are used in the manufacturing of corrugated boxes, each serving specific purposes and offering different levels of strength, durability, and printability. Here are some common types:
- Kraft Paperboard: This is a strong and durable paperboard often used for the outer layers of corrugated boxes. It provides excellent printability, making it suitable for branding and graphics.
- Test Liner: The test liner paperboard is used as the outer layer in corrugated boxes and offers good strength and printability. It’s often made from recycled materials and is an economical choice.
- White-Top Liner: This type of paperboard has a white surface layer, offering a smooth and printable surface for high-quality graphics and branding. It’s commonly used for packaging products where aesthetics are important.
- Coated Paperboard: Coated paperboard has a layer of coating, usually clay or other materials, to enhance its printability and appearance. It’s used for packaging products that require a polished look.
- Recycled Paperboard: Made from recycled fibers, this paperboard is environmentally friendly and commonly used for corrugated boxes. It might have slightly reduced strength compared to virgin fiber paperboard.
- Solid Bleached Sulfate (SBS) Board: SBS board is a high-quality, white, and smooth paperboard. It offers excellent printability and is often used for premium packaging where a high-end appearance is desired.
- Chipboard: Also known as grayboard, chipboard is a thicker and stiffer type of paperboard. It’s often used for the structural components of corrugated boxes, such as partitions and inserts.
- Clay-Coated News Back (CCNB): This type of paperboard is often used for the inner liner layers of corrugated boxes. It has a clay-coated surface that provides a smooth and printable surface.
FAQs
- What is paperboard in the context of corrugated boxes?
Paperboard is a thick, sturdy paper material used for the outer and inner layers of corrugated boxes, providing strength, printability, and protection to packaged items.
- What are the common types of paperboard used in corrugated boxes?
Common types include Kraft paperboard, test liner, white-top liner, coated paperboard, recycled paperboard, SBS board, chipboard, CCNB, and fluting.
- What’s the purpose of using different types of paperboard in corrugated boxes?
Different types of paperboard offer varying degrees of strength, printability, and appearance, allowing manufacturers to tailor boxes for different products and requirements.
- How does paperboard contribute to the strength of corrugated boxes?
Paperboard forms the outer and inner layers of corrugated boxes, providing structural integrity, durability, and protection against external forces.
- Which types of paperboard are more environmentally friendly?
Recycled paperboard and those made from sustainable sources are considered environmentally friendly choices due to their reduced impact on natural resources.
- Can paperboard be customized for branding and graphics?
Yes, many types of paperboard offer excellent printability, allowing for customized branding, graphics, and information on the surface of corrugated boxes.
- Is paperboard used for the fluted layer in corrugated boxes?
No, paperboard is typically not used for the fluted layer. Fluting is a separate layer of corrugated material that provides cushioning and support between the outer liners.
- How does coated paperboard differ from regular paperboard?
Coated paperboard has an additional layer of coating (often clay) that enhances its printability and visual appeal, making it suitable for high-quality packaging.
