11、ion of the Packaging and Freight Containers Standards Policy Committee and supersedes BS 1133:Section 7:Chapter 7.5:1981 which is withdrawn. BS 1133 was originally issued in December 1943, primarily to give guidance on the packaging of Service and other Government supplies. In practice, however, the
12、 code was used not only by Government departments and contractors but also by civilian packers and, accordingly, it was amended to suit commercial requirements. The Parts were later issued separately and new Sections were added as new materials and methods have been developed. Various Sections of th
13、e code have been revised and the most recent revision of the whole of Section 7 was in 1967. Since Section 7 had become large, it was then decided to subdivide it into a number of Subsections to be published separately. This Subsection of BS 1133 dealing with fibreboard cases and fittings is intende
14、d to assist users in choosing the case most suitable for their purpose. In order to obtain a completely satisfactory result, however, it is essential to ensure technical cooperation at all stages between the user and the manufacturer of the package and also to have regard to the means of transport.
15、This revision updates the guidance on fibreboard cases for home trade use in the light of current practice, recognizes the publication of appropriate BS methods of test for the determination of the properties of solid and corrugated fibreboard and deletes material which is properly specification mat
16、erial from this guidance document. The packaging code now consists of the following Sections all of which are published separately, with the exception of Sections 1 to 3 which are published in one volume. Sections 1 to 3: Introduction to packaging; Section 4: Mechanical aids in package handling; Sec
17、tion 5: Protection against spoilage of packages and their contents by micro-organisms, insects, mites and rodents; Section 6: Temporary protection of metal surfaces against corrosion during transportation and storage; Section 7: Paper and board wrappers, bags and containers; Subsection 7.1: Wrapping

22、tish Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

25、cked and it is essential that each problem be considered on its merits by the user and case designer. The choice of a case is governed to a large extent by the character of the contents, their mass, fragility and shape; storage, handling and transport requirements and climatic conditions. The requir
26、ements of automatic handling systems should also be taken into account. 1 Scope This Subsection of BS 1133 gives guidance on fibreboard cases and fitments made wholly of solid or corrugated fibreboard. It does not cover combinations of fibreboard and other materials. NOTEThe titles of the publicatio
27、ns referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this British Standard, the definitions given in BS 3130-1 and BS 3130-2 and BS 3203 apply, together with the following: 2.1 white top kraft a kraft liner having a complete outer furnish of bleached
28、 kraft 2.2 mottled kraft a kraft liner having an uneven density bleached kraft outer surface so that the base colour is visible in patches 3 Application Fibreboard cases are suitable, both as inner and outer containers, for the transport of a wide variety of goods for home trade and export, if neces
29、sary with suitable fitments. 4 Carriage of dangerous goods Purchasers of fibreboard cases for the carriage of dangerous goods need to be aware of the statutory and international regulations relevant to the journey to be undertaken. 5 Materials 5.1 Types of fibreboard The following types of fibreboar
30、d are used for the construction of cases. a) Solid fibreboard. Consists of two or more layers of board laminated together with an adhesive. The board used is called “container middles” and is made from recycled paper. Usually, one or both of the outer layers is kraft paper to give a smooth surface f
31、or appearance and printing purposes. b) Corrugated fibreboard. Consists of one or more sheets of fluted paper (fluting) secured with an adhesive to two or more liners. There are three types: 1) Single wall corrugated fibreboard. Board consisting of one sheet of fluted paper secured between two liner
32、s (see Figure 1). 2) Double wall corrugated fibreboard. Board consisting of two sheets of fluted paper secured between three liners (see Figure 2). 3) Triple wall corrugated fibreboard. Board consisting of three sheets of fluted paper secured between four liners (see Figure 3). The types of flute fo
33、rm are given in Table 1.

34、1990 2 BSI 01-2000 Table 1 Details of flute forms It is convenient when referring to generally available corrugated fibreboards to use the following abbreviations. These abbreviations, with the flute designation A, B, C and E in conjunction with liner grammage can then be used to describe a corrugat
35、ed fibreboard. Each component material is described in turn, starting at the outside of the case and working inwards. The first number and letter(s) combination indicates the grammage of the outer liner and the type of material. After an oblique sign the next letter denotes the flute form and the ne
36、xt number and letter(s) combination, after a further oblique sign, describes the grammage and type of material of the inner liner of the case, for single wall board. Where double wall or triple wall boards are concerned, further flute form and liner descriptions are inserted, using the same notation
37、 and maintaining the order of component materials from the outside to the inside of the case (see examples). Example 1 150K/A/150T A flute, single wall corrugated fibreboard, outer liner 150 g/m2 kraft liner, inner liner 150 g/m2 test liner. Example 2 200BK/B/125C/C/150K BC flute, double wall corrug
38、ated fibreboard, outer liner 200 g/m2 bleached kraft liner, middle wall 125 g/m2 chip liner, inner liner 150 g/m2 kraft liner. NOTEThe grammage and type of fluting should be agreed between customer and supplier to take account of any specific performance requirements. 5.2 Choice of materials 5.2.1 F
39、lute form In theory any of the flute forms listed in Table 1 may be used in single wall corrugated fibreboard and any combination of the forms could be used for double wall or triple wall corrugated. In current practice single wall corrugated for outer containers will typically incorporate either B
40、or C flute with E flute single wall corrugated fibreboard being used mainly for inner containers. Double wall corrugated is typically a combination of B and C flute or sometimes B and A while triple wall corrugated usually comprises combinations of A and C flute forms. 5.2.2 General purpose cases Ta
41、ble 2 gives guidance on the selection of materials for the construction of general purpose cases intended for home trade use. The performance values given in Table 2 in relation to a given mass of contents are to some extent a compromise. For example a definite stacking requirement may dictate the E
42、dge Crush Test (ECT) value required and so control the choice of material. Should protection and containment of the contents be the main requirements preliminary trials may indicate a material having a bursting strength as given in the table and such a material will usually result in the appropriate
43、 ECT value being met. The choice between the types of corrugated fibreboard listed in Table 2 will depend on the actual packaging application. B flute is the most common flute form and gives a greater flat crush strength than C flute for a given weight of fluting medium. The surface quality of B flu
44、te board may be more suitable for high quality printing directly on the board. C flute board contains more fluting medium per linear metre than B flute board and is thicker, both factors contributing to a higher top-to-bottom case compression strength. C flute and double wall are more commonly used
45、where cushioning properties are required. In addition double wall board gives very good stacking strength and resistance to side-wall bulge and will often be the better choice for the packaging of fragile products.

48、e use of closed transport systems and in the case of some types of commodities, a lighter grade of board may be used or the mass of contents may be increased beyond that shown in Table 2. On the other hand a heavier grade of board for a given mass may be necessary for dangerous goods and explosives,
49、 for overseas shipment or for particularly severe transit or storage conditions. The sampling and test methods listed in Table 3 should be used when the properties of a given case are compared with the values given in Table 2. 5.2.3 Heavy duty cases Heavy duty board is a high performance packaging material which is made from heavier weights of liner and fluting medium and constructed in a combination of two or more fluted layers, usually a permutation of “A” and/or “C” flute forms.
