In modern greenhouse farming, the choice of covering material directly affects yield, energy efficiency, and the lifespan of the structure. Among the many options, EVA film stands out — a modified material based on ethylene-vinyl acetate, successfully used in professional greenhouses around the world.
What is EVA Film for Greenhouses?
This is a flexible multilayer film produced by adding ethylene-vinyl acetate (EVA) to base polyethylene. Unlike regular greenhouse film, EVA film has enhanced optical and mechanical properties.
Comparison: EVA Film vs Standard PE Film
| Property | EVA Film for Greenhouses | Standard PE Film |
|---|---|---|
| Light transmission | Up to 90–92% | 85–88% |
| UV stability | High | Medium |
| Elasticity | Excellent | Average |
| Heat retention | Good, lower night heat losses | Faster cooling |
| Tear resistance | Enhanced | Lower |
| Light diffusion effect | Yes (anti-condensation and diffusion) | Usually absent |
Advantages of EVA Film in Agriculture
- High transparency improves photosynthesis efficiency;
- Fogging effect (light diffusion) protects plants from burns;
- Temperature stability — remains flexible even in frost;
- Extended service life — up to 3–5 seasons without loss of properties;
- Anti-condensation effect — prevents drop formation and mold growth;
- Heating cost savings due to better insulation.
Conclusion
EVA film is a modern solution for those who want to get the most out of greenhouse cultivation. Its use improves yield, extends the lifespan of the structure and reduces maintenance costs. If you are planning to modernize your greenhouse or build one from scratch, EVA is definitely one of the best options to consider.
