What is used to wrap the quilt in the greenhouse?

The main function of wrapping the quilt in the greenhouse is to prevent rainwater from entering the inner layer of the quilt from the edge. Second, the interlayer cotton of the quilt in the greenhouse is fluffy and easy to spread when exposed to the outside, so it needs to be wrapped. Therefore, when wrapping, the material is preferably waterproof, and then the corrosion resistance and waterproof are better.
