Packaging

Corrugated container: One of the most efficient forms of distributing packagable goods, a corrugated container is manufactured from containerboard – linerboard and medium. In its most common form, a corrugated box is made from two layers of linerboard and a layer of medium. The layers are combined on a corrugator, a machine that presses corrugations into the medium and laminates a ply of linerboard to each side. The resulting corrugated sheets are printed, folded and glued or stapled to form a finished box. Corrugated containers are designed primarily to protect a product during shipping but increasingly feature enhanced graphics, which increase a product's market appeal.

Folding carton: A paperboard package designed to protect the product during shipment and on the store shelf and to enhance the product's appeal to the consumer. Folding cartons typically feature high-quality graphics to maximize shelf appeal in a retail outlet and to provide information about the product and its use. The market is primarily consumer nondurable goods. Most folding cartons are made from a single ply of paperboard – e.g., recycled in food, paper, soap; SBS for specialty products such as cosmetics.

Paper tubes & cores: Wound cylindrical tubes typically made from uncoated recycled board, most often used as the core around which rolls of paper, film and carpeting are wrapped for shipping. The product category also includes mailing tubes.

 

Paper & Paperboard

Linerboard: The grade of paperboard used for the outer "facings" of a corrugated box. Kraft linerboard is made from wood fiber derived by the kraft process and typically contains no more than 20 percent recycled material. Recycled or testliner may be made of 100 percent recycled material.

Mottled white linerboard: Linerboard manufactured with a layer of white pulp over unbleached kraft material to provide an improved surface for graphics.

Medium: The paperboard grade used to form the inner, fluted layer of corrugated board. Like linerboard, medium can be made of recycled material or wood pulp.

Newsprint: Uncoated paper made predominantly from fiber derived by a mechanical rather than chemical pulping process. The source of the mechanical fiber can be recycled material or wood pulp.

Clay-coated Recycled Boxboard (CRB): A key paperboard grade for folding cartons. CRB is made from recycled material – mainly, old newsprint and old corrugated containers – and coated with a layer of clay to provide a smooth white surface for packaging graphics.

Uncoated Recycled Board (URB): Uncoated paperboard grades manufactured primarily from old newsprint and old corrugated and used in both folding cartons and in the manufacture of paper tubes and cores. URB is typically made on cylinder machines and often referred to generically as cylinderboard.

Solid Bleached Sulfate (SBS): A premium grade of folding carton board, it is a solid sheet of paperboard manufactured from bleached kraft pulp and generally clay-coated on one side.

Groundwood Specialties: An uncoated groundwood containing paper manufactured from mechanical fiber from wood pulp or recycled material. It distinguishes itself from conventional newsprint by having a higher brightness, opacity or other characteristics to provide an improved printing medium.
