最大的区别就是蓝色的大棚膜添加了浅蓝色的色母，
而白色大棚膜没有添加；
在使用上，蓝色的大棚膜并不影响它的透光率，以及质量等方面；
棚膜的质量以及透光率和大棚膜本身厂家的原材料、工艺、技术有关。
一样厚，8丝是薄膜厚度，即0.8mm。
颜色则是工艺和材料决定，
有的白色膜和蓝色膜都是一样带UV涂层和防雾滴的，
不是说白色就一定好。
但是一般常规的薄膜白色的透光度要好一些。
Blue greenhouse film greenhouse film the biggest difference is that blue and white added a light blue color master greenhouse film, greenhouse film and white not added;
In use, the blue greenhouse film does not affect its light transmittance, and quality and so on;
The quality of the films and light transmittance and greenhouse film itself manufacturers of raw materials, process, technology.
As thick, silk is thin film thickness, that is 0.8 mm. Technology and material color is decided, some blue and white membranes are the same with UV coating and the droplets, not to say that the white will be good. But conventional white light transmittance of thin film is better.
