This kind of film has good moisture retention and light transmission, is soft and easy to shape, and is suitable for use as outer covering material for greenhouses, greenhouses and small and medium-sized sheds.
The disadvantages are:(1) Film density, high cost;
(2) easy to become brittle at low temperatures, easy to soften and loosen at high temperatures;
(3) precipitation of additives, film surface dust absorption, affecting light transmission;
(4) residual film can not be degraded and burning treatment.
(2) pvc anti-aging film: effective use period of 8-10 months, has good light transmission, heat preservation and weather resistance;
(3) pvc non-drip anti-aging film: has both anti-aging and drip characteristics, good light transmission and heat preservation, non-drip can be maintained for 4-6 months, safe service life of 12-18 months. Widely used, is the current energy-saving solar greenhouse cover material;
(4) pvc weatherproof drip-free dustproof film: in addition to its weatherproof drip characteristics, the surface of the film has been treated, which is more favorable for winter and spring cultivation in solar greenhouses.
(2) pe anti-aging film: this kind of film has a thickness of 0.08-0.12 mm, a long service life of 12-18 months, and can be used for 2-3 seasons of crop cultivation, which is not only a long service life, low cost and energy saving, but also a significant increase in yield and production value, so it is a key film variety for promotion in facility cultivation;
(3) pe non-drip anti-aging film: it has the advantages of drip, weather resistance, light transmission and heat preservation, etc. The anti-drip effect can be maintained for 2-4 months, and the aging resistance can be 12-18 months, which is a safe and widely used agricultural film.
Reflective agricultural film, translucent film, l-blue light film, mirror reflective film, etc.
Soft texture, easy to shape, good light transmission, non-toxic, is the main agricultural film varieties in China. The disadvantage is that the weather resistance and insulation is poor, not easy to bond.
