SBS stands for Solid Bleached Sulphate and it is basically a thick paperboard. SBS is made purely from bleached chemical pulp so it is white and had a beautiful print surface. You will see SBS mentioned on our site as a paper option for Counter Cards. One of the available options to print your Counter Cards on is an ultra-thick 56-point SBS Board. A frame of reference for scale: a credit card is 30-point thick and a penny is about 48-point thick. Check or order out Counter Cards here https://www.4over4.com/printing/counter-cards
