Solid bleached board (SBB) or solid bleached sulphate (SBS) is a virgin fibre grade of paperboard. This grade is made purely from bleached chemical pulp and usually has a mineral or synthetic pigment [ 1 ] coated top surface in one or more layers (C1S) and often also a coating on the reverse side (C2S).
Corrugated fiberboard made from paperboard. Paperboard is a thick paper-based material.While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.30 mm, 0.012 in, or 12 points) than paper and has certain superior attributes such as foldability and rigidity.
Vacuum is used to assist a firm fit. The film bonds to the heat-seal coating on the paperboard. The substrate can be either made specifically for skin packaging, or converted from other paper stock, such as corrugated board. The specially made sheets Solid Bleached Sulfate (SBS) are porous, and allow the vacuum to flow directly through the paper.
Common sizes include 22 + 1 ⁄ 2 in × 28 + 1 ⁄ 2 in (572 mm × 724 mm) and its bulk thickness is 0.006 inches (0.15 mm) or higher [2] and A4, A3, A2 and A1. [3] [4] Bristol board may be rated by the number of plies it contains, basis weight, or, in Europe, by its grammage of 220 to 250 g/m 2.
Solid unbleached board, also known as SUB, is a grade of paperboard typically made of unbleached chemical pulp. Most often it comes with two to three layers of mineral or synthetic pigment coating on the top and one layer on the reverse side. Recycled fibres are sometimes used to replace the unbleached chemical pulp.
Playing cards, which require a very rigid single sheet with high surface durability and printability. Paperboard is a paper-based material, usually more than about ten mils (0.010 inches (0.25 mm)) thick. It is often used for folding cartons, set-up boxes, carded packaging, etc. Configurations of paperboard include:
Paper composite panels are a phenolic resin/cellulose composite material made from partially recycled paper and phenolic resin.Multiple layers of paper are soaked in phenolic resin, then molded and baked into net shape in a heated form or press.
Homasote is a brand name associated with the product generically known as cellulose-based fiber wall board, which is similar in composition to papier-mâché, made from recycled paper that is compressed under high temperature and pressure. Homasote contains no adhesives.
