What physical performance indicators should high-quality cotton packaging film have
2025-10-13
Essential Physical Properties of Quality Cotton Packaging Film
-
Tear Resistance
Critical for withstanding friction and impacts during logistics. Prevents small scratches from developing into large gaps that could allow contaminants to enter and damage cotton fibers.
-
Tensile Strength
Maintains film integrity when stretched during packaging and when supporting stacked bale weights. Prevents breakage that could lead to loose packaging and potential cotton loss.
-
Moisture Barrier Performance
Blocks external moisture while allowing minimal air circulation. Prevents mold growth and quality degradation while avoiding trapped condensation that could harm cotton quality.
-
Heat-Sealing Strength
Creates durable, leak-proof seals that resist peeling or breaking during transport. Maintains bale shape and prevents accidental package openings that could expose cotton to contaminants.
-
Puncture Resistance
Protects against sharp objects from handling equipment or bale edges. Particularly crucial for long-distance transport or rough terrain where puncture risks are elevated.
-
Dimensional Stability
Maintains consistent size/shape despite temperature/humidity fluctuations. Prevents shrinkage/expansion that could create packaging gaps or looseness during storage and transport.
