MATERIAL HANDLING EQUIPMENT8. CartonsDisposable container used to unitize and protect loosediscrete itemsTypically used for distributionDimensions always specified as sequence: Length × Width ×Depth, where length is the larger, and width is the smaller, of the two dimension of the openface of the carton, and depth is the distance perpendicular to the length and widthLarge quantities of finished carton blanks or knocked-down cartons can be stored on pallets untilneeded9. BagsDisposable container used to unitize and protect bulk materialsTypically used for distributionPolymerized plastic (“poly”) bags available from light weight (1 mil.) toheavy weight (6 mil.) in flat and gusseted stylesDimensions of bag specified as: Width × Length, for flat bags, andWidth × Depth (half gusset) × Length, for gusseted bags10. Bulk load containersReusable container used to unitize and protect bulk materialsIncludes barrels, cylinders, etc.Used for both distribution and in-process handling11. CratesDisposable container used to protect discrete itemsTypically used for distribution12
3. LOAD FORMATION EQUIPMENT12. Intermodal containersReusable container used to unitize and protectloose discrete itemsEnables a load to be handled as a single unit whenit is transferred between road, rail, and seamodes of transport; e.g., the container can beunloaded from a cargo ship and loaded onto atruck as a single unitIt is not as common to use intermodal containersfor airfreight transport because of aircraft shapeand weight restrictionsStandard outside dimensions of intermodalcontainers are: 20 or 40 ft. in length; 8 ft. inwidth; and 8, 8.5, or 9.5 ft. in height; less 8 in. oflength, 5 in. of width, and 9.5 in. of height todetermine the inside dimensionsTypical sea transport costs per 40-ft. container are: $3000–4000 from Japan to the US westcoast, $4000–5000 from Singapore to the US west coast, and $2500–3500 from Europe to theUS east coast; transport costs for a 20-ft. container is 70% of the costs of a 40-ft. container 713. Strapping/tape/glueUsed for load stabilizationStraps are either steel or plasticPlastic strapping that shrinks is used to keep loads frombecoming loose during shipment14. Shrink-wrap/stretch-wrapUsed for load stabilizationAllows irregular loads to be stabilizedIn shrink-wrapping, a film or bag is placed over the load andthen heat is applied to shrink the film or bag; manual orautomatic; most shrink-wrap applications are being replacedby stretch-wrappingIn stretch-wrapping, a film is wound around the load while thefilm is stretched; as compared to shrink-wrapping, stretchwrappinghas lower material, labor, and energy costsStretch-wrap machine13
