THE TERM PULP is used to describe theraw material for the production of paper and allied products such as paper-board, fiberboard, and dissolving pulp for the subsequent manufacture of rayon, cellulose acetate, and other cellulose products. More specifically, pulp is wood or other biomass material that has undergone some degree of chemical or mechanical action to free the fibers either individually or as fiber bundles from an enbodying matrix. Paper,... 

Another application of ICP-MS in the area of food safety is the evaluation of food contact materials. Q [86] and TOF [87] mass spectrometers have been employed in the compositional analysis of paper and board material intended for food contact. Studies on the migration of metals from food contact plastics using food simulants and ICP-MS detection have also been reported. One of them showed how to analyze different simulants without the need of any time-consuming preparation, that is, aqueous acetic acid (3 percent w/v) directly, aqueous ethanol (15 percent v/v) after proper dilution, the olive oil simulant following emulsion preparation by means of tetralin and Triton X-100 [88]. 

Exemplified by paper and board materials with a heterogeneous, open network of fibres with large air spaces or channels. Low molecular weight substances in particular can migrate rather rapidly with little hindrance offered.

Substances linked with producing odour and taint include short chain aldehydes. In paper and board, these are considered to derive from the degradation of lipids. Pentanal, hexanal, heptanal and nonanal were shown to be volatilised from paper and board materials heated at 60 to 100 °C (Wenzl and Lankmayr, 2002). Other substances were also detected in the headspace above the test samples but were not identified. Whilst transfer to foods was not investigated in these studies, the fact that they were shown... 

Whilst there is considerable evidence to indicate that substances can volatilise from and/or transfer through packaging materials to the gas phase, there are very few studies on gas phase transfer to foods. Indirect evidence for gas phase transfer to foods was seen in studies by Anderson and Castle (2003) who measured levels of benzophenone in foodstuffs packaged in printed cartonboard materials. Benzophenone is a photoinitiator used in some UV cure inks for the printing of paper and board materials and has been shown to be present in printed paper and board materials indicating that it remains in the paperboard after printing (Johns et al 1995). 

This adhesive is a resin/solvent adhesive material compounded to supply satisfactory initial tack. The solvent system has been carefully selected for somewhat rapid evaporation, thereby requiring minimum temperature and ventilation. Useful in textiles and paper board industries. 

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. ...

Paper and board materials intended for food packaging have been found to contain a large number of toxic organic compounds in them These include alkyl and aryl aldehydes, BHT, di-tert-bu-tylphenol, and substituted benzophenones. [6°1... 

In the late 1960s Olin s managers decided to spin off Squibb (and with it. Beechnut, as described in Chapter 7), which was quickly transformed into a major pharmaceutical enterprise. With the proceeds from that move, Olin acquired in 1969 an aluminum extrusion company and two large residential construction companies. By 1971 chemicals accounted for only 25 percent of sales, metals 28 percent, fine paper 7 percent, crafts and other paper-board packaging materials 16 percent, firearms and defense 18 percent, and... 

All uses are related to the function requirements which are necessarily linked to the material properties and characteristics. Details of material tests for paper, board, cartons and corrugated are given in Appendices 5.1-5.4. 

In short, paper board and other cellulosic materials have a major future in this industry. 

In the flat as sheets or reels, e.g. paper, board, tinplate, films, foils and laminates. Materials in both sheet and reel forms may be further processed to give packs which may remain in the flat (e.g. collapsible cartons) until erected or are directly fabricated into a three-dimensional container (tinplate containers, composite drums, rigid boxes, etc.). Distortion printing also falls into this category. 

Paper, board and plastic can all be produced as a coloured material. With plastic, colour can be introduced by dry or wet colourising or masterbatching.
