Cotton bales loose weight during the storage after pressing. Major portion of the moisture applied before pressing escapes from the bale till the time of bale dispatch. During winter, The humidity remains very low during the day time and also dry wind blows during the day time. Hence cotton bales loose the moisture. In summer, the temperature, sunlight exposure & lower humidity make the cotton bales dry & also the quality is deteriorated.

Risk Management

Bale banding materials are typically constructed of steel bands, high tensile steel wire ties or plastic (polyethylene terephthalate) bands. It is especially critical that bale banding materials be strong enough to withstand the static loads containing the fibres in bales as well as impact forces of handling. Broken bands can represent a significant risk because of probable loss of fibre weight, inefficient handling, and contamination potential.

Heavy bales can create much higher bale strapping forces than bales of average weight. Research has shown bale forces increase exponentially with increases in density; therefore, in a bale having a fixed length band, density increases in proportion to its weight increase. Similarly, a bale which may be formed with varying distribution of lint across its cross section is also subject to band breakage. Ginners usually discover quickly if lint distribution is a problem and make corrective adjustments before significant problems arise. Temperature and humidity changes also affect internal bale forces. Moisture conditions for the cotton fibre during compression are a significant factor: the lower the moisture content, the higher the force on the bale bands
