High-quality cotton baling film features a dense, impermeable structure that acts as a physical barrier against external moisture. When properly applied, the tight wrapping eliminates gaps that could allow rain, dew, or humidity to penetrate. This moisture protection is crucial as cotton's absorbent nature makes it vulnerable to mold growth and fiber quality deterioration during storage and transportation.

The film forms a protective layer that isolates cotton from dust, dirt, debris, and pests. By preventing contaminants from settling on fibers, it maintains cotton purity for subsequent processing. The tight seal also deters pests like insects and rodents from accessing the bales, as they cannot penetrate the film's surface.

Film effectiveness depends on proper application techniques. Loose wrapping, tears, or holes compromise protection. Ensuring correct wrapping methods and using intact, high-quality film are essential for maximizing moisture and contamination resistance throughout the supply chain.

When used correctly, cotton baling film provides robust protection that preserves cotton quality and commercial value. Its dual-function against both moisture and contamination makes it indispensable for modern cotton storage and transportation solutions.
