Offset Paper Paper: designed for use in offset lithography. Important properties include good internal bonding, high strength, dimensional stability, lack of curl, and freedom from fuzz and foreign surface material. Used on both sheet-fed and web presses. This is commodity offset.
Premium/Opaque Offset: High quality offset markedly brighter and more opaque than Offset Paper as defined above. It is usually produced in smooth and vellum finishes and may have a companion cover paper. This is a mid-range product between Offset Paper and higher quality papers in the Text and Cover category.
Old Corrugated Containers (OCC): A fiber source comprised of old corrugated containers or old boxes which are collected/recovered from the waste stream. The boxes are converted into pulp, which is then used to make corrugating medium and other types of paperboard.
Packaging Papers: These papers are used to wrap or package consumer and industrial products such as grocer’s bags and sacks, shopping and merchandise bags, and multiwall shipping sacks used for shipping such products as cement, flour, sugar, chemicals and animal food. “Specialty” packaging papers are used for cookies, potato chips, ice cream, and similar products.
Paperboard: One of the two subdivisions of paper. The distinction is not great, but paperboard is heavier in basis weight, thicker, and more rigid than paper. All sheets 12 points (0.012 inch) or more in thickness are classified as paperboard. There are exceptions. Blotting paper, felts, and drawing paper in excess of 12 points are classified as paper while corrugating medium, chipboard, and liner board less than 12 points are classified as paperboard. The broad classes within paperboard include container board, box board, and all other paperboard.
