english When does cotton bale wrap film need to be replaced
2025-04-26
Cotton bale wrap film usually needs to be replaced in the following situations:
1. Obvious damage
When there are tears, cuts or large holes on the surface of the film, it will seriously affect its protective effect on the cotton bale. For example, during transportation or storage, the cotton bale comes into contact with sharp objects, causing the wrapping film to be damaged, and external dust and moisture can easily enter the cotton bale, causing the cotton to be contaminated or deteriorated due to moisture. At this time, the wrapping film needs to be replaced in time.
2. Aging and brittle
After being exposed to the natural environment for a long time, the wrapping film will gradually age due to the influence of ultraviolet rays, temperature, humidity and other factors. The aged film will become fragile and brittle, losing its original flexibility and tensile strength. Even if there is no obvious damage, it may break during transportation or storage due to the pressure of the cotton bale. Generally speaking, if the surface of the wrap film is found to be cracked, hardened or brittle, it should be considered to be replaced to ensure the safety of the cotton bale.
3. Decreased viscosity
The cotton bale wrap film relies on its own viscosity to fix the cotton bale and prevent it from loosening. If the viscosity of the film decreases significantly and cannot effectively wrap and fix the cotton bale, it needs to be replaced. The reason for the decrease in viscosity may be improper storage conditions, such as too high or too low temperature, or too long storage time. When it is found that the wrap film cannot fit the cotton bale tightly and is prone to loosening, it means that the viscosity is insufficient and a new wrap film needs to be replaced.
4. Decreased protective performance
If the cotton bale is subjected to unexpected impact, extrusion, etc. during storage or transportation, even if the surface of the wrap film is not obviously damaged, its internal structure may have been damaged and the protective performance has decreased. In addition, after repeated use, the various properties of the wrap film will gradually decrease. In these cases, in order to ensure that the cotton bale is well protected, it is also necessary to replace the new cotton bale wrap film
