Low-grade or recycled materials with inconsistent composition result in weaker tensile strength and flexibility. Inadequate manufacturing processes (uneven thickness, incomplete material fusion) create weak points that break under tension during application.

Excessive tension during wrapping stretches film beyond capacity, weakening molecular structure. Uneven wrapping creates stress concentrations where tightly wrapped sections bear more pressure, increasing tear likelihood when contacting bale edges or equipment.

Cold temperatures make film rigid/brittle, while heat softens it and reduces tensile strength. Abrasive surfaces (rough bale edges, ground debris, worn machinery) gradually weaken film through surface abrasion, leading to sudden tearing during use.

Addressing film quality standards, operator training for proper tension control, and environmental protection measures can significantly reduce tearing incidents and improve cotton bale protection throughout the supply chain.
