Timber products:
Higher level of smoothness than uncoated paper achieved by applying a coating (typically clay based) on the surface of the paper.
As a result, higher reprographic quality and printability is achieved. Uses include brochures, catalogues, corporate communications
materials, direct mail, promotions, educational textbooks, luxury advertising, magazine covers and upscale magazines.
Uses include business forms, business stationery, general printing paper and photocopy paper. We also produce tissue wadding which is
converted into various hygiene products.
Can be either coated or uncoated. Uses include bags, labels, packaging and release paper for casting textered finishes (eg artificial leather).
Heavy and lightweight grades of paper and board primarily used for primary and secondary packaging of fast moving consumer goods,
agricultural and industrial products. Products include containerboard (corrugated shipping containers), sack kraft (multi-walled shipping
sacks) and machine glazed kraft (grocers bags). Can be coated to enhance barrier and aesthetic properties.
Manufactured from groundwood and bleached chemical pulp. Uses include advertising inserts and newspapers. Demand is highly
dependent on newspaper circulation and retail advertising.
A coated groundwood fibre based paper, primarily used for magazines, catalogues and advertising material.
Main raw material used in the production of printing, writing and packaging paper. Pulp is the generic term that describes the cellulose
fibre derived from wood. These cellulose fibres may be separated by mechanical, thermo-mechanical or chemical processes.
The chemical processes involve removing the glues (lignins) which bind the wood fibres to leave cellulose fibres. Paper made from
chemical pulp is generally termed ‘woodfree’ or ‘fine’ paper.
Manufactured by similar processes to paper pulp, but purified further to leave virually pure cellulose fibres. Chemical cellulose is used
in the manufacture of a variety of cellulose textile and non-woven fibre products, including viscose staple fibre (rayon), solvent spun fibre
(lyocell) and filament. It is also used in various other cellulose-based applications in the food, cigarette, chemical and pharamaceutical
industries. These include the manufacture of acetate tow microcrystalline cellulose, cellophane, ethers and moulding powders.
The various grades of chemical cellulose are manufactured in accordance with the specific requirements of customers in different
market segments. The purity of the chemical cellulose is one of the key determinants of it’s suitability for particular applications with
the purer grades of chemical aellulose generally supplied into the speciality segments.
Sawn timber for construction and furniture manufacturing purposes.
