Solid Bleached Sulfate (SBS) paperboard is made from bleached virgin wood pulp. Usually, it comes coated with a naturally occurring mineral called kaolin clay to help with surface smoothness for printing. Additionally, SBS paperboard can be coated with a thin plastic liner to create a food-safe moisture barrier that helps preserve odors and flavors, making this material ideal for packaging food, cosmetic and pharmaceutical products. SBS paperboard comprises 20% recycled materials and 80% freshly harvested wood chips which are chemically processed and bleached, giving it a brilliant white color.
