Paperboard packaging

Patent Granted Paperboard is a thick paper-based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.25 mm, 0.010 in, or 10 points) than paper. According to ISO standards, paperboard is a paper with a basis weight (grammage) above 224 g/m2, but there are exceptions.[1] Paperboard can be single- or multi-ply. Paperboard can be easily cut and formed, is lightweight, and because it is strong, is used in packaging.
