Introduction
Cotton picker bale wrap film is a specialized polyethylene packaging material. It work with automatic cotton picker machines to wrap compact cotton modules during harvesting.
Standard plastic films cannot fit high-speed mechanical wrapping. They tear easily or fail to seal tight under field tension.
Custom cotton bale wrapping film provide stable tension resistance, UV protection and waterproof performance. It keep raw cotton clean and undamaged from field to storage.
Five-layer co-extruded PE film is the mainstream type for modern cotton harvesting. It match most mainstream self-propelled cotton picker equipment.
Core Specifications of Cotton Picker Bale Wrap Film
Size and thickness decide wrapping compatibility and durability. Most farm machines have fixed film roll parameters.
Standard film width reaches 2.7 meters or 106 inches. This size fit common large cotton bale dimensions.
Industry standard thickness range from 60 microns to 100 microns. 75-micron grade is the most widely used for daily harvesting work.
Regular roll diameter is 25 centimeters. It fit standard on-board film holders of cotton picker machines.
Performance Data Comparison of Common Film Grades
Mechanical performance directly affect wrapping success rate and cotton preservation effect. The table below list verified test data for mainstream cotton picker bale wrap film products.
Performance Index | 60μm Standard Film | 75μm Premium Film | 100μm Heavy-Duty Film |
Portrait Tensile Strength (MPa) | 20.1 | 25.1 | 29.8 |
Horizontal Tensile Strength (MPa) | 22.3 | 27.1 | 32.5 |
Elongation at Break (%) | 480 | 531 | 620 |
Right Angle Tear Strength (kN/m) | 92 | 110 | 128 |
Puncture Resistance (N) | 3.2 | 4.1 | 5.3 |
75μm premium film balance cost and performance best. It meet most commercial cotton farm harvesting demands.
Heavy-duty 100μm film suit harsh field conditions. It resist sharp branch piercing and strong wind impact.
Key Functional Features
High Tensile and Tear Resistance
Qualified cotton picker bale wrap film use modified PE raw materials. It withstand fast mechanical stretching during automatic wrapping.
No crack or break happens in normal machine operation. It ensure full bale coverage every time.
UV and Aging Resistance
Professional film add anti-UV additives. It block sunlight damage during long-term field stacking.
It prevent film brittle failure and cotton yellowing. It extend bale storage time up to 12 months.
Full Waterproof and Dustproof
Five-layer co-extrusion structure eliminate tiny gaps. Rainwater and field dust cannot penetrate the film layer.
Wrapped cotton bales keep clean and dry. It avoid quality loss before ginning processing.
Compatible Cotton Picker Models
Most universal bale wrap film fit mainstream cotton picker machines. CP690 and CP770 harvesting systems work well with standard film rolls.
The film match automatic module wrapping cycles. It support 32-second fast wrapping for standard cotton modules.
It adapt to bale weight range from 2200kg to 2700kg. No loose wrapping or film waste occurs.
Field Installation and Usage Tips
Check film roll tightness before installation. Loose rolls cause uneven wrapping during machine running.
Adjust machine tension parameters according to film thickness. Too high tension break thin film. Too low tension lead to loose bales.
Store unused film rolls in dry and shaded warehouses. Direct sunlight reduce film toughness in advance.
Replace worn film rolls in time. Old film with reduced toughness affect harvesting efficiency.
Industry FAQ
Q1: What film thickness is best for regular cotton field harvesting?
75 micron cotton picker bale wrap film is the most suitable option. It has balanced tensile strength and cost, fit most daily harvesting scenarios.
Q2: How long can wrapped cotton bales be stored outdoors?
Qualified anti-UV wrap film support 10 to 12 months outdoor storage. It keep cotton quality stable with no obvious aging.
Q3: Why do ordinary PE films fail on cotton picker machines?
Ordinary films lack modified tension and tear resistance. They cannot bear high-speed mechanical stretching and always tear during wrapping cycles.
Q4: What is the main advantage of five-layer co-extruded wrap film?
It has better waterproof, anti-puncture and anti-aging performance. The layered structure improve overall durability than single-layer film products.
