What is SBS Paperboard?
SBS paperboard, which we stock in C1S and C2S, is a solid, fully bleached paperboard sheet. SBS paperboard can be finished in various ways, though most commonly it has a bright white color and smooth coated surface. These products offer many benefits, including superior printing and packaging capabilities. Because of these capabilities, C1S and C2S SBS paperboard are often used for food trays, folding cartons, food packaging and various other applications across many industries.
SBS Paperboard Manufacturing Process
Solid Bleached Sulfate (SBS) paperboard is made of bleached virgin wood pulp or recycled paper that’s compressed to form paperboard material. The manufacturing process often consists of five stages to take the raw material to a smooth sheet.
Here’s a closer look at each of the stages:
1. Raw Material Stage
Wood pulp is used for the majority of new paper production, though recycled materials are becoming more common and preferred as environmental awareness continues to grow.
2. Pulping Stage
Once the raw materials are gathered, they’ll go through one of two pulping processes — chemical pulping or thermo-mechanical pulping. Chemical pulping uses chemicals to turn the raw materials into pulp, while thermo-mechanical pulping applies pressurized steam to soften the raw materials into pulp.
3. Bleaching Stage
The lignin in pulp means the material is naturally dark. Recycled paperboard pulp may have chemical residue that makes it a gray color. To lighten the color and increase the purity of the paperboard, the pulp can be bleached, though this isn’t always required.
4. Plies Stage
Some uses of paperboard require multiple plies of paper. In this stage, the pulp is layered to create the desired number of plies for the application.
5. Coating Stage
Coatings of a pigment or adhesive are added to each layer of the paperboard as the final stage. These final coatings are added to increase the gloss, whiteness and smoothness of the paperboard.
Benefits of Using SBS Paperboard
Paperboard is a versatile material with numerous benefits. Using SBS paperboard for packaging offers the following benefits:
- Compression strength: SBS paperboard can withstand the compression of packaging to keep products fresh.
- Clean cuts and creases: The density of the paperboard allows for clean cuts or creases when folded.
- Holds ink well: Paperboard is good for printing high-quality graphics because it can hold the ink better than other materials.
- Recyclable: Paperboard can be broken down and recycled into new paperboard.
- Hygenic: SBS paperboard has no smell or taste, so it’s perfect for packaging things like cosmetics.
