PE film: it is often said that polyethylene film, clarity and heat sealing is good, moisture-proof, waterproof.

Difference: Compared with PE film, PO film has stronger light transmittance and stronger digestion and absorption temperature working ability. The light transmittance of the greenhouse is 4.5-4.7% higher than that of the PE film, and the daily temperature of the greenhouse is also 1℃ higher than that of the PE film.

Second, how to choose PO film and PE film
