This double layer inflated film greenhouse is a high-efficiency, thermal insulation commercial facility engineered for large-scale cultivation of delicate ornamentals, seedlings, and cold-sensitive crops. Constructed with a reinforced hot-dip galvanized steel frame and a unique double-layer PO/PE film structure, it creates a stable air-insulated layer between the two film layers, delivering exceptional thermal retention, anti-fog performance, and weather resistance. The integrated automatic inflation system maintains optimal air pressure in the interlayer, making it an ideal low-energy, cost-effective solution for cold regions and high-value horticultural production.

✅ Superior Thermal Insulation: The double air-layers form a natural thermal barrier that reduces heat loss by over 40% compared to single-layer greenhouses, significantly cutting winter heating costs.
✅ Stable Air Pressure System: Equipped with a high-performance automatic inflation unit that monitors and maintains constant air pressure in the interlayer, ensuring structural stability and consistent insulation performance.
✅ Premium Anti-Fog & UV Film: 150/200μm double-layer PO film with anti-fog coating ensures 90%+ light transmittance without internal condensation, protecting crops from leaf burn and disease.
✅ Strong Wind & Snow Load Resistance: The reinforced arch steel frame is specifically designed to support the weight of the double film structure, withstanding heavy snow and strong winds effectively.
✅ Low Maintenance & Long Service Life: The double film structure is resistant to tearing and aging, with a service life of 3-5 years, while the steel frame ensures 15+ years of operation.
✅ Cost-Effective Climate Control: Eliminates the need for excessive heating in winter, providing a stable climate for high-value crops with minimal energy input.

Pressure Maintenance
The automatic inflation system runs continuously to maintain the interlayer air pressure. Check the pressure gauge daily; add air manually if the pressure drops below the standard threshold.
Climate Control Setup
Use the central control unit to set temperature and humidity parameters. The double film acts as a natural insulator, reducing the load on heating/cooling systems.
Irrigation Management
Utilize drip irrigation to deliver water and nutrients, avoiding excessive moisture that could lead to mold under the stable film.
Daily Maintenance
Inspect film for tears or damage, especially at roof joints and side walls. Clean ventilation openings regularly to prevent clogging.
Seasonal Adjustment
In winter, ensure the inflation unit works efficiently to maintain insulation levels. In summer, use side ventilation windows and shading nets to prevent overheating.
Pre-Operation Check
Inspect steel frame connections, film tension, and the automatic inflation unit before daily use. Ensure all ventilation windows are sealed tightly.
A: The double layer creates an air-insulated cavity that acts as a thermal blanket, reducing heat loss significantly. It also provides better protection against hail and strong winds compared to single-layer films.
Q2: What happens if the inflation unit breaks down?
A: The greenhouse is designed with a manual backup inflation system. In case of electrical failure, the manual pump can be used to maintain air pressure temporarily, preventing the film from sagging or collapsing.
Q3: Is this greenhouse suitable for commercial flower production?
A: Absolutely, it offers exceptional temperature stability and uniform light distribution, which are crucial for producing high-quality potted plants and ornamentals.
Q4: Can the greenhouse be equipped with heating systems?
A: Yes, it can be integrated with hot air or heating pipe systems. The double film structure maximizes the efficiency of these heating units, resulting in lower energy consumption.
Q5: What is the HS code for export?
A: The general HS code is 9406900090, final confirmation is subject to your local customs broker.
