SBS C1S stands for Solid Bleached Sulfate Coated One Side. It is made from high-purity bleached chemical wood pulp. The front side has a smooth, coated surface that is ideal for high-quality printing, while the uncoated back side provides good glue absorption for box assembly.
If both sides need to be printed or a more consistent surface appearance is required, SBS C2S may be a better option. For packaging used in high-humidity or cold-chain environments, lamination or additional moisture protection is recommended.
SBS C1S has a smooth and even surface, consistent whiteness, and excellent color reproduction, helping printed text and images appear sharp and clear. Compared with many other paper materials, it also offers good dimensional stability, with less risk of deformation or discoloration during long-term storage and use. SBS C1S is also recyclable after use, making it a suitable option for brands looking for recyclable packaging materials.
