Where to source them, prices, uv and wear resistance, spec sheets, advantages/disadvantages, etc., etc.
Flexible kites are made using fabrics, while the solar balloon is made using plastic film.
The xf-film is a plastic (polyethylen multi-layers http://www.barrierbac.com/process.html) film, that is not good for kites (excepted pehaps for static kites) due to both low dimensional qualities and low (but high in regard to other plastic films) tear resistance, with perhaps an exception for not crosswind kites with low efficiency (L/D ratio) like parachutes. In the other hand its UV resistance is very high (I tested its lifetime outdoor for more than 3 years (I indicated 2 years by mistake)), far higher than fabrics and other plastic films.
