Material: PE+EVA Mixed. Q&A to Choose&Use Greenhouse Plastic Film Properly: 1- How to choose color? There are several colors for optional as covering material, Transparent, Sky-Blue, Yellow, Purple, etc. Different colors have different features. Transparent--Good for plants to carry out photosynthesis. Most widely used! Almost suitable for all plants! Sky-Blue----- Good to promote the synthesis of chlorophyll and increase the temperature inside! Popular Style. Yellow--------- Some Rate of sunshine shading. Purple--------- Increase the light transmittance; Increase plants colored. So purple film is better for colored plants, especially that is hard to be colored,like grape, etc. 2- What is the best material for covering plastic film?Usually there are 3 materials for plastic film: PVC.PE&EVA. 1) PVC: Good in light transmission and warm-keeping. But with the character of high density, high cost, easily embrittling&relaxing and air-pollution when cremating, this material is now used seldom. 2) PE/Polythene: Outstanding for its light, soft, easy modeling, good light transmission, no air-pollution. It is now the most widely used as covering and ground film material. But it is poor for weather resistance and warm-keeping. 3) EVA / Ethylene Vinyl Acetate: Eva is easy to be mixed with kinds of weather resistance and warm-keeping material to make good film. Good for low temperature. So as we can see, different material has different features. Our plastic film use the “3/5-layers to-extruding’ technology and make full use of strong points of the three material to make our plastic film outstanding for its long life, light, warm-keeping, etc. The basic material used is as follows: Outer ply: PE+ Anti-UV material; Middle ply: warm keeping layer: EVA+PE;Inner ply: 80%EVA.
