EN 13891:2003 (E)41 ScopeThis European Standard gives guidance on the selection and use of steel and non-metallic tensional strapping.The term steel strapping covers flat band strapping. Non-metallic strapping covers weftless strapping and extrudedthermoplastic strapping.NOTE 1EN 13246 specifies the breaking strength and dimensional tolerances of steel strapping and gives guidance onsurface finishes of steel strapping.NOTE 2EN13394 specifies the dimensional tolerances and tensile properties of non-metallic tensional strapping andweftless (textile) strapping and gives guidance on surface finishes available.2 General2.1 ApplicationsTensional strapping is applied to packages by semi-automatic, automatic. or automated equipment (see clause 4)and tied or sealed while under tension. It may be applied to wooden boxes or crates, solid and corrugatedfibreboard packaging cases, bundles, bales, palletized and unitised loads, to manufacturing processes, and as asafety factor in internal handling, e.g. temporary banding.2.2 PurposeMany of the recommendations set out in other Sections of this European Standard provide for the use of tensionalstrapping, applied correctly, as an integral part of the container or package. Some reasons for this are as follows:a) it reinforces and strengthens packages, protecting them against the hazards of transportation, thus assistingand ensuring safe arrival at destination;b) it allows economies to be effected in load constructions and on other packaging materials;c) it renders the contents of the packages less liable to pilferage;d) it may be used as a method of closure or of reinforcing the closure.In addition, certain conditions experienced in handling and transit require the use of strapping as an additionalsafeguard, e.g. load restraint.2.3 Lifting and lashingOnly certain grades of tensional steel strapping are designed to be used for mechanical lifting purposes (see EN13247). Other grades of tensional steel strapping should not be used for lifting purposes.NOTENon-metallic strapping should not be used for lifting purposes.2.4 Choice of strappingIn determining the size, number and type of straps to be used, consideration should be given to the shape, sizeand distribution of mass of the package or load, the material from which it is made, and the handling, storage andtransport conditions likely to be encountered.NOTEEN 13246 specifies tensional steel strapping.EN 13394 specifies non-metallic tensional strapping.SIST EN 13891:2003



EN 13891:2003 (E)53 Types of equipment3.1 For use with steel and non-metallic strappingThe types of equipment for use with steel and non-metallic tensional strapping are listed in Table 1. There is a fullrange of options with various degrees of mechanisation with additional options, if required.The advice and guidance of manufacturers are offered freely in evaluating the requirements of a given strappingapplication and recommending suitable systems. Within the types of equipment set out in Table 1 there areobviously special features designed for specialised applications as well as secondary factors which will enhancestandard equipment. Suppliers will provide the detailed information upon which a choice can be made.Table 1 — Types of equipment for use with steel and non-metallic strappingHand operatedPower assisted, portableFully powered, portableSemi-automatic machinesAutomatic machinesSemi-automatic pack compressionAutomatic pack compressionCustom automatic machinesNote
Suppliers should be consulted to advise on the suitability of strapping tomeet the requirements of specific application equipment.3.2 For use with semi-automatic, automatic and automated types of strappingThe types of equipment recommended for use with semi-automatic, automatic and automated types of strappingequipment are classified as follows.a) Semi-automatic: Machinery, generally static, which does not have a strap chute for feeding strapping aroundthe article to be strapped. Feeding is by hand, the machine operator placing the leading end of a strap into themechanism so that the remaining operations of the cycle, i.e. tensioning, sealing and cutting off, can becompleted automatically.b) Automatic: Machinery with a fixed track for feeding the strapping. All operations of the complete strapping cycleare carried out on activation of the start control.c) Automated: Automatic machinery with additional electronic or other controls and a powered method ofpresenting packs to the strapping machine. An automated system could be capable, without the presence ofan operator, of
