BENEFITS of STANDARDIZED BALE SIZES and PACKAGING BENEFITS of Size does matter STANDARDIZED BALE SIZES Bale dimensions and packaging vary from country to and country and, at times, within countries or regions. PACKAGING Bales vary in size and weight between 80 and 330 kg depending on country of origin. Presented by: David E. Mrozinski Vice President International Sales Continental Eagle Corporation BENEFITS of BENEFITS of STANDARDIZED BALE SIZES STANDARDIZED BALE SIZES and and PACKAGING PACKAGING Historical Bale Sizes in the USA prior History of Bale Standardization in the USA to Universal Density The Joint Cotton Industry Bale Packaging Committee (JCIBPC) was formed at the suggestion of both the American Textile Manufacturers Institute (ATMI) and the National Cotton Council (NCC). U.S. Cotton Gin and Press manufacturers along with Trucking Unions, Cotton Buyers and Textile Industry representatives have been key members and contributors since its inception in 1968. BENEFITS of BENEFITS of STANDARDIZED BALE SIZES STANDARDIZED BALE SIZES and and PACKAGING PACKAGING Various Bale Types and Densities Change is not immediate Universal Density (UD): Cotton bale density of at least 450 kg / cu meter (28 lbs per cu ft). Gin UD: Bale compressed at the gin to a density of at least 450 kg / cu meter (28 lbs per cu ft). (Bale must be tied with strapping or wire). In the United States existing presses were producing the Compress UD: Flat/modified flat bale recompressed at warehouse to a density of at nominal 21 x 55 bale size, but at varying densities. The least 450 kg / cu meter (28 lbs per cu ft). Committee, over the next 4 years, decided to continue to Standard Density (SD): Cotton bale density of at least 368 kg / cu meter (23 lbs per cu ft). but less than 450 kg / cu meter (28 lbs per cu ft), Bales must be tied with use the 20x54 bale presses and agreed that the 28 lb/cu ft strapping or wire.

Compress SD: Flat/modified flat bale re-compressed at warehouse to a density of at least 368 kg / cu meter (23 lbs per cu ft), but less than 450 kg / cu meter (28 lbs per By 1972 the first “Universal Density” proto-type presses cu ft). By 1972 the first “Universal Density” proto-type presses Flat/Modified Flat: Cotton bale density of less than 368 kg / cu meter (23 lbs per cu were introduced and in 1973 the first commercial UD ft) with flat bale density normally at 192 kg / cu meter (12 lbs per cu ft) and modified presses were being produced. flat bale density at 224 kg / cu meter (14 lbs per cu ft). Unless otherwise noted, reference to flat bales in specifications also includes modified flat bales. High Density (HD): Cotton bale density of at least 512 kg / cu meter (32 lbs per cu It was not until the late 1980’s when the United States was ft). nearly completely changed over to UD. Super High Density: Cotton bale density of at least 577 kg / cu meter (36 lbs per cu nearly completely changed over to UD. ft).

BENEFITS of BENEFITS of STANDARDIZED BALE SIZES STANDARDIZED BALE SIZES and and PACKAGING PACKAGING Transport Transportability Bale size and density are considered to be critical for the most economical loading of available modes of transportation These include Wagons, Lorries, Long-Haul Trucks, Rail Cars and Ocean-going Containers • Maximum allowable weight • Maximum number of bales • Loading and Handling Efficiency 2 BENEFITS of BENEFITS of STANDARDIZED BALE SIZES STANDARDIZED BALE SIZES and and PACKAGING PACKAGING Packaging Packaging To efficiently and economically provide end users with high quality cotton there are some general guidelines, including Bale Ties storage and handling considerations for reducing Bale Bags and Wraps contamination. Labeling Each of these sections is further divided into General Requirements and Approved Materials. Specifications for each material approved by the Bale Packaging Committee BENEFITS of BENEFITS of STANDARDIZED BALE SIZES STANDARDIZED BALE SIZES and and PACKAGING PACKAGING Tying is essential to maintain compression of the bales Tying during transport and storage. If the ties are damaged or broken, compression is diminished. • Inability to stack efficiently Cotton is shipped in large rectangular • Reduction in storage and handling efficiency • Damage to the packing material allows contamination bales, compressed to varying densities. The bales are tied firmly with steel or plastic straps or wire. BENEFITS of BENEFITS of STANDARDIZED BALE SIZES STANDARDIZED BALE SIZES and and PACKAGING PACKAGING Round Wire: Steel material having a circular cross-sectional area applied to restrain cotton bales Bale wraps damaged to remove samples – possibility of after compression. Contamination increased from direct exposure Ovalized Wire: Steel material having a cross section slightly modified from a circular cross section applied to restrain cotton bales after compression. There is no significant difference (minus 5% tolerance) in cross-sectional areas between round wire and ovalized wire. The linear densities External Bands may cause the fibers from the bags to break and (weight per foot of wire) of ovalized and round wires are equal. become embedded in the bale causing additional contamination Waisted Wire: Steel material having a reduced cross-sectional area between the joint portions and a non-reduced, round cross section in the portion that the joints are formed. The linear density that is very difficult to remove of waisted wire is lower than that of round wire. Recessed Wire: Bale tie recesses describe grooves, indentions or notches created in the flat or External banding reduces pressing capacity "hard" sides of the cotton bale, located such that when bale tie materials are applied, ties (wires or bands) lie within the depth of the recess; recesses are sufficiently deep so that ties are protected from normal handling impacts with floors, lift truck handling devices and other bales; in addition to minimizing handling stresses on bale ties, recesses are intended to reduce tearing and cutting of bagging normally associated with shearing action of ties on bagging; exact width and depth dimensions are not specified, except that grooves should be sufficiently wide to accommodate the width of band or wire tie and sufficiently deep so that the tie does not extend beyond the outside plane of the bale surface. Strapping: High tensile steel or polyester material having a flattened, rectangular cross section applied to restrain cotton bales after compression. Slip-Seal: One type of strapping connection to secure strap ends together. Seal has heavy indentions across width of strap. Connection allows for limited movement or slippage of bottom strap. For use with 3/4-inch x 0.025-inch strap in either a 6-band or 8-band configuration. Fixed-Seal: Strapping connection in which relative movement of strap ends cannot occur. Refers to triple notch seals. Triple-Notch: One type of fixed-seal strapping connection in which strap ends are secured by indenting and locking a metal seal around strap ends. For use with 3/4-inch x 0.031-inch strapping in an 8-band configuration only. 3 BENEFITS of BENEFITS of STANDARDIZED BALE SIZES STANDARDIZED BALE SIZES and and PACKAGING PACKAGING Bale Ties Packaging Protects Cotton Bales from: These factors will determine the cost/benefit • Contamination ratio • Dampness • Fiber Loss Type of Bale Ties Type of coating or finish on the Ties They are wrapped completely in cotton, jute, plastic fabric, or sometimes in plastic films perforated so as to Number of Ties per Bale regulate bale moisture content.
