Black and White Silage Film

Black and White Silage Film has excellent aging resistance and resistance to acid, alkali, and organic solvents, ensuring that it will not decompose or release harmful substances or damage the quality of silage feed in acidic environments.

1. Innovative Dual-Layer Design & Core Functionality

The film’s intelligent “White-outside, Black-inside” design assigns specific roles to each layer for superior performance:

White Outer Layer:

Solar Reflection: Effectively reflects sunlight and solar heat, significantly reducing the internal temperature of bales under direct sunlight. This prevents overheating and undesirable fermentation.

UV Resistance: Contains high-performance UV inhibitors that protect the film itself from solar degradation, preventing brittleness and extending service life in outdoor storage.

Black Inner Layer:

Total Light Blockage: Provides complete opacity, shielding the silage from ultraviolet rays that destroy essential nutrients like vitamins A and E, and carotene. This preserves the nutritional value and color of the feed.

Chemical Resistance: Highly resistant to the acidic conditions of fermentation, ensuring the film remains intact and does not degrade upon contact with the silage.

2. Advanced Material & Enhanced Performance

Exceptional Strength and Durability:

Manufactured from imported polyethylene raw materials and enhanced with metallocene technology. This significantly increases the film’s tensile strength and puncture resistance, reducing the risk of tearing during wrapping, handling, and transport.

Superior Weather and Chemical Stability:

Formulated with anti-oxidants and light stabilizers to withstand long-term exposure to sun, rain, and temperature fluctuations, ensuring stable performance and durability.

Offers excellent resistance to acids, alkalis, and organic solvents, guaranteeing that no harmful substances are decomposed or released into the silage, thus safeguarding feed safety and quality.

Effective Moisture Barrier and Thermal Insulation:

Black and White Silage Film is 100% waterproof, providing an impermeable barrier against rain and dew to maintain a stable, dry internal environment.

Features excellent infrared (IR) blocking capabilities, minimizing heat loss through radiation. Working in synergy with the reflective white layer, it creates an effective insulating layer that helps maintain a consistent temperature and moisture level for optimal lactic acid fermentation.

3. Correct Usage Instructions

For optimal results, it is crucial to ensure:
The white side must face upwards (towards the sun/sky), and the black side must face downwards (in contact with the forage).

This correct orientation maximizes the sun-reflecting and insulating properties of the white layer while utilizing the total light blockage and corrosion resistance of the black layer, working together to maintain a stable fermentation environment and prevent nutrient loss.

Core Advantages :

Reflects Heat – White outer layer lowers temperature 5-8°C
Blocks Oxygen – 99.5% barrier (ASTM D3985 certified)
Boosts Nutrition – <5% dry matter loss vs. 30% in uncovered silage
Strong & Long-Lasting – 3-layer metallocene LLDPE, 3-5 year UV resistanc

Black and White Silage Film Applications: Bale wrapping, silage pits, TMR (Total Mixed Ration) bunkers.
