Many roducts, such as cellulose fibres an of textile fibres (in Chapter 54). Where the textile fibres paper and are classified as nonwovens f To avoid discrepancies which can result fiom the use of different methods, it is highly desirable that all administrations use the International Organization for Standardization (ISO) test methods to determine the ph sical properties of paper and pa erboard of Chapter 48.

PREPARATION OF THE PULP The pul is repared by blendin if necessary, mixin with fillers, size, or colourin matter as requlreb: anBreduction to a suita le consistency by di ution in water and mechanical eating. f % % The fillers, which are generally of inorganic origin (e.g., kaolin (China clay), titanium dioxide, calcium carbonate) are used m order to increase opaci , improve printability or economise pulp. Size (e.g., rosin mixed with alum) is used to render e paper less absorbent to ink, etc. x FORMATION OF THE SHEET OR WEB (A) Machine-made paper and paperboard. The most commonly used method of this process the pulp, after endless band of man-made with a vibratory movement; or suction boxes placed along the form of a limp web. In some machines this web then asses under a wire-covered roll (dandy-roll) where it is consolidated and smoothed and, i?i required, is given a watermark produced, e.g., by an embossed design or line effect applied to the surface of the dandy roll cover. The web next passes to an endless belt of felt and so to the press section where it is further consolidated; it is then dned by passing over heated cylinders. An alternative method is the twin wire former (used articularly in newsprint manufacture . The ulp asses between two forming rolls and is carrie between two " wires ". Water is de ected !&om\oth wires, aided by suction boxes sad suction rolls, and the web is formed. The newly er sections. The twin wires forming both sides of formed web is drawn to the ressing and the aper are alike, thus e lminating the elt side and wire side which characterise paper pro uced by the Fourdrinier process. $ B F In other types of machines the Fourdrinier wire is re laced by a large cylinder (" mould ") covered with wire gauze revolving partly immersed in i e prepared pulp. The cylinder takes up a layer of ulp and forms it into a paper web which is transferred to drying felts either in continuous engths or, by dividing the surface of the roll, in sheet form. In a variation of the process, layers are allowed to build up around a large diameter roll to be cut off when the required thckness is reached. S Machines with multiple wires or cylinder moulds (or a combination of Fourdrinier wire and cylinder moulds) are used to make boards composed of layers (sometimes of different colour or quality) produced simultaneously and rolled together in the wet state without the use of adheslve. (B) Hand-made paper and paperboard. In the manufacture of hand-made pa er and aperboard the essential operation of moulding the pul fibres into sheet form is per ormed y hand, even though other operations may be per orrned by machine. ! I? i Hand-made paper and paperboard may be made fiom any paper-making material but generally best grade linen or cotton rags are used. In forming the sheet, a quantity of ulp is agitated on a sieve-like mould until most of the water is removed and the fibres felted. &e sheet is then removed fiom the mould, pressed between felts and hung up to dry. The hand mould on which the fibres are felted together may consist either of parallel-laid wires or of woven wire cloth which produce watermarks on the paper. Watermark designs may also be affixed to the wire. The characteristic properties of hand-made a er are strength and durability and the- uality of the grain. These properties render it suitab e or special uses, e.g., banknote paper, ocument paper, drawing paper, etching paper, special filter papers, ledger paper, mounting aper hi class rinting or stationery papers. It is also used for malung wedding cards, etterhea s calm ars, etc. ! f! ' P B ,t Hand-made aper is normally made to size as used and has four deckled edges with marked feathering; i e s e may, however, sometimes be trimmed and in any case are not a reliable distin shing feature since some machine-made apers, particularly mould-made paper, also have eckled edges which are not, however, so mar edly feathered. Y % FINISHING OPERATIONS Pa er may be finished by calendering or supercalenderin (being first moistened if necessary), eitEer by calenders integral with the paper-making mac ine or separate from it; this gives a more or less polished or glazed surface on either one or both faces. A similar surface on one side of the pa er ma be obtained b using a heated cylinder. The paper may also receive a$I'nd o false Almost all ordinary writing, printing and drawin papers are with some kind of glue or starch solution, genera y in order to their resistance to the penetration and spreading of aqueous % ? B Coated paper and paperboard This term applies to paper or pa erboard which has been given a coating on one or both sides either to produce a specially g ossy finish or to render the surface suitable for particular requirements. S Coating products generally consist of mineral substances, binding agents and other additives necessary for the coating operation, such as hardeners and dispersing agents. Carbon paper, self-cop and other copying or transfer papers, in rolls or sheets of particular dimensions, fall in he 'ng 48.09. d Paper and paperboard, coated with kaolin (China clay) or other inorganic substances, with or without a binder, in rolls or sheets, fall in headin 48.10. In addition to kaolin, the inor anic substances used for coating include barium sulp ate, calcium carbonate, calcium sulp ate, ma esium silicate, zinc oxide, and powdered metal. These coating materials are generally a p ied by means of a binding agent such as glue, gelatin, amylaceous substances (e.g., starch, Zxtrin), shellac, albumin, synthetic latex. Products are coated with kaolin, etc., to attain a glossy, dull or matte finish. Examples of products coated with kaolin or other inorganic substances are : coated printing papers and paperboard (includin coated art or chromo papers), coated foldin carton stock, apers coated with metal powder $other than stamping fo~lsof headin 32.1 ) or mica pow er, enamel papers (used largely for labels and for covering boxes). It may e noted that the binding agents used for fixing the coatin , such as glue or starch, are also used for surface sizing but in the case of an uncoated s&ce sized paper, the coating pigments are absent. t y % % tions mentioned in the headin ,paper and paperboard with a coating of tar, or other or anic rnateria s such as wax, stearin, textile dust, sawdust, in rolls or s eets, fall in heading 48.1 I. These coating materials may not require a binding agent for their ap lication. The coatings are used to obtain the physical characteristics for a broad range of en$ uses, for exam le, for waterproof packages, release aper and paperboard. Such coated papers and paperboar s include gummed or adhesive paper, Rock papers (coated with textile dust and used for box coverings and wallpaper), paper coated with granulated cork (used as packing material), graphite paper, tarred wrapping paper. fl B B Colouring materials are also frequently added to the coating medium. Many coated papers and aperboards are finished with a high loss by super-calendering, or the B coahng may be varnishe in order to protect it fiom moisture for example). $ in the case of washable papers, It is possible to distinguish between surface sizing and coating by using a combination of chemical and physical methods. In most cases, differentiation can easily be made either on the basis of the nature or quanti of the material present or on the basis of the overall physical characteristics. In general, in t e case of surface sizing, the appearance and texture of the natural surface of the paper or paperboard are maintained, whereas, in the case of coated paper or paperboard, the irregularities of the natural surface are substantially eliminated by the coating material. 3; Problems may arise in borderline cases, particularly for the following reasons : low coated papers may have had the coatin applied in the size press; certain substances present in coatings also exist in paper itself (e.g., fi ler); and fibres may be visible in the case of papers coated with material which does not contain a igrnent, e.g., an aqueous dispersion of poly(viny1 chloride). However, it should be possible to eal with these cases by one or more of the methods indicated below. f a r Many coated pa ers, such as mineral-coated art rinting papers, cannot easily be distin ished by the eye fiom ighly finished uncoated papers. h e coating, however, may sometimes e seen by scraping the surface or be removed by immersion in water. R One method of testing which may determine whether or not a paper is coated articularly with inorganic substances) involves sticking the aper to an adhesive ta e. When e tape is peeled off most of the coatin adheres to the tape. 1;t IS then necessary to Jssolve the wood fibres and any starch resent on ta e with cupriethylene diamine. The presence or absence of a coatin is indicate8by comparing t e weights of the tape before and after these operations. This metho can also be used for papers coated with organic substances. kK a Among other methods used for identifying coated aper and paperboard are scanning electron microscopy (SEM), X-ray diffraction and infia-re spectrophotometry. These can be used for identifying products of both headings 48.10 and 48.1 1. d' Coloured or printed paper and paperboard These include papers printed by an rocess with one or several colours, stripes, motifs, designs, etc., and also surface rnarb e or jaspC papers. These papers are used for various purposes such as box covering and bookbinding. 7 d' Paper may be surface-printed in ink of any colour with lines, whether parallel, conver ent, or at an angle. Such aper is used, inter ulju, for account books and book-keeping, schoo exercise books, drawing ooks, manuscript music sheets and books, writing paper, graphpaper and note books. f i This Chapter includes printed pa ers (such as wrapping papers for individual traders, printed with names of traders, trade mar s and devices, directions for use of merchandise) provided that the rinting is merely incidental to the use of the paper for wra kg, writing, etc., and that the goo s do not constitute printed matter of Chapter 49 (see Note to this Chapter). E F! d' Impregnated paper and paperboard Most of these papers and paperboards are obtained by treatment with oils, waxes, plastics, etc., in such a manner as to permeate them and ive them special qualities (e.g., to render them waterproof, greaseproof, and sometimes trans went or transparent). They are used largely for protective wrapping or as insulating materials. Impregnated papers and paperboards include, oiled wrapping paper, oiled or waxed manifold paper, stencil pa er, insulahng pa er and paperboard impregnated, e.g., with plastics, rubberised paper, paper andl' paperboard mere y impregnated with tar or bitumen. Certain papers such as wallpaper base may be impregnated with insecticides or chemicals. Tbis Chapter also includes cellulose waddin and webs of cellulose fibres which consist of a variable number of very thin layers of loose y felted cellulose fibres rolled together when in a damp condition so that the layers tend to separate on drying. f SCOPE OF THE CHAPTER This Chapter covers : (I) Paper, paperboard, cellulose wadding and webs of cellulose fibres, of all kinds, in rolls or sheets : (A) Headings 48.0 1, 48.02, 48.04 and 48.05 relate to machine-made uncoated apers subjected, if required, to sizing and simple finishin processes (e.g., calen enng, glazing). Heading 48.02 also covers uncoated han -made papers, which may be subjected to those same processes. Heading 48.03 relates to uncoated papers of a kind used for household or sani purposes, cellulose wadding and webs of cellulose fibres, which may be subjecte to processes mentioned in the heading. Note 3 to this Chapter specifies the processes emitted for paper, paperboard, cellulose wadding and webs of cellulose fibres, of hea mngs 48.01 to 48.05. S d3 B The processes adrnissibIe in headings 48.01 to 48.05 are perfonned as a art of the continuous paper-manufacturing run. A characteristic of the papers of these eadings is that the appearance and texture of their naturaI surface are maintained. In the case of coated papers, the irregularities of the natural surface are substantially eliminated by the coating material which forms a new, superior, non-cellulosic surface. R (B) Headings 48.06 to 48.1 1 relate to certain special papers or paperboards, (for example, parchment, easeproof, composite) or paper, paperboard or cellulose wadding and webs of cel ulose fibres which have been subjected to various treatments, such as coating,. design printing, ruling, impregnating, corrugation, creping, embossing, and perforation.
