When choosing the best packaging material, solid bleached sulfate (SBS) is often a top choice — especially in industries where a clean look, strong structure, and good print quality are important. SBS is used in a variety of items, like cosmetic boxes and food containers. It’s a high-grade paperboard known for its smooth surface and great performance. In this article, we’ll discuss what SBS is, how it’s made, where it’s commonly used, and why it’s still a top option for packaging that needs both strength and style.
What Is Solid Bleached Sulfate (SBS)?
Solid bleached sulfate is a type of paperboard made from purified wood pulp that has been chemically treated and bleached. It has a bright white color, a smooth finish, and a strong structure. Unlike some other paperboards that use recycled or unbleached fibers, SBS is made entirely from clean, chemical pulp, which gives it a pure, consistent look. This material is often coated with clay or a layer of polyethylene (PE) to make it better for printing or to protect it from moisture, especially for food packaging.
Characteristics of Solid Bleached Sulfate Board
SBS is a popular choice in the paperboard industry for several reasons.
Here are some of its key features:
1. Bright White Appearance:
Because SBS is made from bleached pulp, it has a bright white surface both on the inside and outside. This makes it great for designs that need a clean background or sharp colors.
2. Excellent Printability:
SBS is very good at holding detailed graphics and bright colors. It works well with different printing methods such as offset, flexo, or digital. The smooth surface ensures crisp, clear results.
3. Strong and Foldable:
Even though it looks smooth and refined, SBS is strong and rigid.It can be scored, folded, and cut without breaking — making it ideal for boxes, sleeves, and other packaging that needs precise edges.
4.Safe for Food Use:
SBS is made from pure fibers, so it’s safe for food packaging. Some versions have a special coating to stop moisture and grease, which makes them suitable for packaging frozen foods, baked goods, and fast food items.
Common Uses of Solid Bleached Sulfate Paperboard
SBS is used in a wide range of industries where design and safety matter.
Some of the most common uses include:
- Cosmetic and beauty packaging
- Pharmaceutical cartons
- Food and beverage boxes
- Greeting cards and promotional materials
- Folding cartons
What Is 24 Point Solid Bleached Sulfate?
The thickness of a paperboard is measured in points, with one point being 1/1000 of an inch.So, 24 point SBS is 0. 024 inches thick. This is a medium to heavy-weight option in the SBS range and offers a good balance between flexibility and strength.
Why Choose 24 Point SBS?
Structural Strength:
24 point SBS is good for making boxes and containers that need to be sturdy.
Print Quality:
It has a smooth surface that works well with printing methods and gives sharp, clear results.
Premium Feel:
It gives a high-quality, elegant look that is perfect for upscale packaging.
Versatility:
Many premium boxes, like those for cosmetics, tech products, or sweets, are made with 24 point SBS because of its strength and look.
Sustainability and Recyclability
Even though SBS is not made from recycled materials, it is still considered a sustainable option when it comes from well-managed forests. Many SBS makers offer FSC-certified versions. Additionally, SBS is fully recyclable and can break down in nature, making it a good choice for brands that want to balance quality with environmental responsibility.
In some cases, SBS may have a coating, like polyethylene, to protect it. However, the recyclability of these coated versions depends on the local recycling system and whether the coating can be removed during the recycling process.
Final Thoughts
Solid bleached sulfate paperboard is a top choice for packaging in many industries because of its versatility, strength, and clean look. Whether you need to print detailed logos for cosmetics, make a sleek folding carton, or create food-safe containers, SBS provides a bright white surface with excellent strength and smoothness.
With medium-weight options like 24-point SBS, you get a balance between durability and print quality. Its widespread use in beauty, food, healthcare, and retail shows how reliable and visually appealing it is.
