How to Choose Greenhouse cover film 丨AX GREENHOUSE FOCUS ON PROFESSIONAL DESIGN & GUIDANCE SERVICES

In the face of the increasing number of greenhouse cover film products, many farmers are at a loss as to which shed film to choose. The performance and applicability of several types of shed films are introduced as follows. 

Polyvinyl chloride (PVC) film

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. 

plastic film

The main products are: (1) ordinary pvc shed film: the use period is 4-6 months, can produce one crop season, is being gradually eliminated; 
(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. 

Polyethylene resin (pe) film

The main products are: (1) ordinary pe shed film: the use period is only 4-6 months, production is gradually eliminated;  
(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. 
It can be used in greenhouses and small, medium and large sheds, and is also suitable for early spring cultivation of energy-saving solar greenhouses;
(4) pe insulation shed film: it can stop infrared radiation to the atmosphere and improve the insulation effect of greenhouses by 1-2oc, which is better in cold areas; 
(5) pe functional composite film: it has various functions such as drip-free, heat preservation, weather resistance and long life, such as dimming film that can selectively transmit light and make full use of solar energy, including reflecting light. make full use of sunlight energy, including reflective agricultural film, 
Reflective agricultural film, translucent film, l-blue light film, mirror reflective film, etc. 
Plastic film

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. 

Having said that, do you have further knowledge and updated understanding of choosing greenhouse covering film material? Do you need to have such an exclusive design, then come and visit our Aixiang Greenhouse ! We are looking forward to your arrival!
