What is SBS (Solid Bleached Sulfate) Paperboard?
Definition and Overview
SBS paperboard, also known as Solid Bleached Sulfate, is a high-quality material made from bleached virgin wood fibers. It is widely recognized for its smooth, bright white surface, which provides an excellent canvas for vibrant and detailed printing.
Manufacturing Process
SBS is produced using a specialized process that involves the use of bleached virgin fibers. During production, these fibers are chemically treated to remove impurities and achieve a pristine white finish. The resulting paperboard is then coated for enhanced printability and durability.
Characteristics of the Production Method:
- Utilization of bleached virgin fibers ensures a clean, consistent appearance.
- Coating layers improve moisture resistance and surface smoothness.
Key Features
- Bright, Smooth Surface: The clean, white finish of SBS makes it ideal for premium packaging designs.
- Excellent Printability: Its smooth texture allows for high-quality printing with sharp, vibrant graphics.
- Moisture Resistance: The coated surface provides protection against moisture, making it suitable for various environments.
Common Applications
- Pharmaceutical Packaging: Ensures a professional, clean look for medicine boxes.
- Premium Food and Beverage Packaging: Perfect for upscale products requiring a high-end presentation.
- High-End Cosmetics Packaging: Elevates the brand image with its luxurious appearance.
What is SUS (Solid Unbleached Sulfate) Paperboard?
Definition and Overview
SUS paperboard, or Solid Unbleached Sulfate, is made from unbleached wood fibers, giving it a natural brown appearance. It is known for its strength, rigidity, and cost-effectiveness, making it a popular choice for heavy-duty and eco-friendly packaging.
Manufacturing Process
The production of SUS paperboard involves the use of unbleached wood fibers and lignin, which contributes to its natural brown color and robust structure. To enhance its printability, the surface is often coated with a clay layer.
Characteristics of the Production Method
- Incorporation of lignin ensures high strength and durability.
- Clay-coated surface allows for improved printing quality.
Key Features
- Natural Brown Appearance: Provides an earthy, eco-conscious aesthetic.
- Durability and Rigidity: Ideal for packaging heavy or bulky items.
- Cost Efficiency: Typically more affordable than SBS paperboard.
Common Applications
- Beverage Carriers: Strong enough to hold multiple bottles or cans.
- Hardware Packaging: Suited for tools and industrial items.
- Eco-Friendly Packaging Solutions: Meets the demand for sustainable packaging options.
