Overview of Cotton Module Wrap Film
Cotton module wrap film is a specialized agricultural packaging material. It designed for wrapping and sealing harvested cotton modules.
Farmers use cotton bale wrap film to cover loose cotton modules after picking. It replaces traditional manual covering methods.
Unwrapped cotton modules easily absorb moisture and dust in open fields. It cause cotton quality drop and economic loss.
Standard cotton module wrap film provide full surface sealing protection. It keep cotton clean and dry during field storage and transportation.
Agricultural field tests show qualified UV-stabilized wrap film reduce cotton moisture regain rate by 81% in outdoor storage cycles.
Core Material and Structural Features
Most commercial cotton module wrap film adopt modified polyethylene material. mLLDPE and LDPE are the two main base polymers.
High-grade cotton wrap film add professional UV stabilizers. It resist long-term sunlight aging in open farm environments.
The film have uniform thickness and good ductility. It stretch evenly during automatic baler wrapping process.
Tight molecular structure block water and dust penetration. It no affect cotton breathability and internal drying speed.
Performance Parameter Comparison Table
Material formula and production process decide film durability and wrapping effect. The table below list verified standard industry data.
Film Type | Standard Thickness | Tensile Strength (MD) | Elongation at Break | UV Resistance Lifespan | Main Usage |
Ordinary LDPE Wrap Film | 70 microns | 78 N/5cm | 480% | 3–4 months | Short-term cotton storage |
Modified mLLDPE Module Film | 75 microns | 85 N/5cm | 620% | 6–8 months | Long-term field stacking |
Heavy-Duty UV Stabilized Film | 78 microns | 90 N/5cm | 650% | 10–12 months | Cross-season outdoor storage |
75 micron mLLDPE cotton module wrap film is the most cost-effective option for most cotton farms. It balance strength and weather resistance.
Higher elongation value let the film fit irregular module surfaces tightly. It avoid loose wrapping and gap leakage.
Key Functional Advantages
Cotton module wrap film have multiple practical benefits for large-scale cotton harvesting.
It has excellent puncture resistance. Hard cotton debris do not pierce the film during wrapping and moving.
Integrated waterproof structure stop rainwater infiltration. It prevent cotton mildew and quality degradation.
Anti-aging formula avoid film brittle cracking under strong sunlight. It maintain intact wrapping state for months.
Standard roll size support high-speed automatic baler operation. It improve farm wrapping efficiency greatly.
Baler Equipment Compatibility
Professional cotton module wrap film follow unified industry size standards.
The common roll width is 2.7 meters or 106 inches. It fully match mainstream cotton picker and baler models.
Standard roll diameter is 25 cm. It fit most on-board film fixing brackets without manual modification.
Each regular film roll contains 24 wrapping portions. It reduce frequent roll replacement during continuous harvesting work.
Field Usage and Storage Rules
Correct use extend cotton module wrap film service life and protect cotton quality better.
Complete wrapping right after cotton module forming. Do not leave modules exposed overnight.
Keep flat ground for module stacking. Uneven ground cause film local extrusion and rupture.
Store unused film rolls in dry and shaded warehouses. Long-term light exposure damage UV protective performance.
Avoid sharp tool collision during handling. Artificial damage is the main cause of film failure in field work.
Industry FAQ
Q1: What is cotton module wrap film used for?
A: It is professional agricultural wrapping film. It seals cotton modules after harvesting, protects cotton from moisture, dust and sunlight damage during field storage and transit.
Q2: What thickness is standard cotton module wrap film?
A: 75 microns is the most widely used standard thickness. It offers balanced tensile strength, stretch performance and weather resistance for general farm use.
Q3: How long can UV stabilized wrap film protect cotton modules?
A: Qualified heavy-duty UV stabilized film can protect cotton modules for 10 to 12 months in outdoor open-air environments.
Q4: Is mLLDPE material better than ordinary LDPE for cotton wrapping?
A: Yes. mLLDPE film has higher elongation, better puncture resistance and longer anti-aging life. It suit long-term outdoor cotton module storage.
