greenhouse film

2. Key Performance Characteristics

Optical Properties

• Light Transmission: 88-92% (400-700nm PAR spectrum)

• Diffusion Efficiency: 40-75% haze for shadow-free illumination

• UV Blocking: 0-100% customizable (typically 5% UV-A transmission for pest control)

Physical Properties

Climate Control Features

• IR Absorption: Reduces nighttime heat loss by 25-35%

• Anti-Drip: Surface tension modifiers prevent condensation droplets

• Cooling Additives: NIR-reflective pigments reduce interior temps by 4-7°C

3. Material Technology

Layer Construction

1. Outer Layer: UV-stabilized LDPE (12-24 month UV protection)

2. Middle Layer: EVA/LLDPE blend for strength & flexibility

3. Inner Layer: Anti-fog treatment with copolymer additives

Advanced Options

• Photoselective Films: Custom light spectrum filtering

• Self-Cleaning: Nano-coating reduces dust accumulation

• Biodegradable: PLA-based films (1-2 year lifespan)

4. Installation Guidelines

Structural Requirements

• Frame spacing ≤1.5m for 150μm film
