Film Greenhouses: More Than Just "Plastic Sheds"
The core of a film greenhouse is its "film," but it’s far from an ordinary plastic bag. The mainstream film materials today are PE (polyethylene) and PO (polyolefin). Among them, PO films have become the top choice for most farmers, thanks to their high light transmittance (over 85%), anti-aging properties (with a lifespan of 2-3 years), and anti-condensation features (reducing damage to seedlings from water droplets).
The frame is mostly made of hot-dip galvanized steel pipes—lightweight yet corrosion-resistant. The structure can be scaled up or down: from small, dozens-of-square-meters family gardens to large, multi-span greenhouses covering tens of thousands of square meters, adapting flexibly to different planting needs.
Compared to glass greenhouses, film greenhouses cost over 60% less and are easier to install. A single shed can be set up in just a few days, making them especially friendly to farmers with limited funds.
