Wood is composed of three major polymeric materials cellulose, hemicelluloses, and lignin. Cellulose is the common name used for the glucan present in wood, which constitutes about 42 percent of wood s dry weight. Cellulose is the primary component of the walls of cells making up wood fibers and is the main structural material of wood and other plants. Paper, paperboard, and other wood fiber products thus also are composed mostly of cellulose. The chemical structure of the cellulose macromolecule is shown in Fig. 28.4. In the plant the degree of polymerization (DP) of cellulose is approximately 14,000.5...

Different methods of coating are used to meet different coated product requirements (Table 10.1). The coating materials are in different forms ranging from liquids to solids. They include emulsion, latex, dispersion, lacquer, powdered plastic composition, plastisol, organosol, rubber composition, hot-melt, reacting TS compound, etc. The product could be plastic film, paper, paperboard, woven fabric, plywood, nonwoven fabric, steel sheet, aluminum foil, irregular flat or shaped products, 260... 

TAPPI Testing Procedures. TAPPI publishes a comprehensive set of test methods for the evaluation of pulp, paper, paperboard, and paper-making materials. Several of these methods are useful to archivists, librarians, and conservators. As the cost of the complete set of standards is substantial, TAPPI has made available as a separate set a group of standards (36) entitled TAPPI Standards and Suggested Methods Suitable for Use in the Examination of Paper for Books, Documents, and Works of Art on Paper . 

Paper, paperboard, and cardboard containers are used ubiquitously in pharmaceutical manufacturing. Because these types of containers are rarely designed to interact with the drug product itself, they are not as comprehensively validated in most compendial evaluations. Paper, paperboard, and cardboard are very inexpensive easy to print identification, instructions, or advertising materials and easily adhered to other packaging components. Furthermore, paper is a key component in several designs implemented to comply with tamper-resistant packaging mandates. ... 

The most common applications of paper, paper-board, and cardboard are in blister lidding stock and in over-the-counter (OTC) outer packaging. Because paper, paperboard, and cardboard offer virtually no moisture or gas barrier, they are typically part of the secondary pharmaceutical container. To provide additional protection, paper can be laminated or coated with a variety of materials. More commonly, when paper is involved in critical packaging functions, it is the only one component of a multicomponent system that offers optimal environmental protection to the drug environment. ... 

Other uses of paper, paperboard, and cardboard are as secondary packaging or for shipping packaging...

International Paper is one of the world s largest paper, paperboard, and packaging producers, serving customers in over 130 countries with 30% of its 1998 sales originating from outside the United States. 

Solvent-based adhesives, hot-melt adhesives (paperboards, cardboards), dispersion adhesives (for further information refer to Section 5.2). Tip For bonding of papers, paperboards, photos and the like, glue-sticks - available for detatchable and nondetachable bonded joints - are recommended because of their convenient application (Section 5.8). Solvent-based adhesives, dispersions, hot-melt adhesives, contact adhesives (for further information refer to Section 9.5).

The solid surface to be coated is called the substrate. It may be only slightly deformable a slab, panel, bar, pipe, drum, wafer, disk, ball, or more complicated shape. Or, it may be thin and flexible a sheet, film, wire, or fiber. It may in addition be compressible, as are paper, paperboard, non woven and woven fabrics. When the substrate is a sheet, fabric, or film that is very long or, because of on-line splicing to the next length is... 

Many substrates, including paper, paperboard, cellulose film, fireboard, metal foils, or transparent films are coated with resins by direct extrusion. The resins most commonly used are the polyolefins, such as polyethylene, polypropylene, ionomer, and ethylene-vinyl acetate copolymers. Nylon, PVC, and polyester are used for a lesser extent. Often combinations of these resins and substrates are used to provide a multiplayer structure. [A related technique, called extrusion laminating, involves two or more substrates, such as paper and aluminum foil, combined by using a plastic film, (e.g., polyethylene) as the adhesive and as a moisture barrier.] Coatings are applied in thicknesses of about 0.2-15 nuls, the common average being 0.5-2 mils, and the substrates range in thickness fi om 0.5 to more than 24 mils.
