The present invention relates to a foamed fluororesin film having a thickness of 100 to 200 μ with FE selected. That is, the present invention, as shown in FIG.
In addition to foaming the fluorine resin inside the cylinder, outside the cylinder, that is, as shown in FIGS. 3 and 4, the film 2 is taken up by a take-up roll 3 and wound up, and the take-up roll 3 is cooled to 160 ° C. This cooled 16
The foaming layer 4b of the base film 4 that contacts below 0 ° C. is foamed. As an embodiment, a case where it is used in a greenhouse greenhouse will be described. As the fluororesin film, ETFE having a thickness of 100 to 200 μ is most suitable. Conventionally, 100 to 200 μ of polyvinyl chloride has been used for greenhouses, but the service life is short.

It also has excellent heat retention. c: Compared with a solid film, the foamed fluororesin film has heat retention and is suitable for greenhouses. Especially, there is little heat radiation at night. d: Light. Although the thickness is 100 to 200 μ, its weight is extremely lighter than that of vinyl chloride. Further, in the case of vinyl chloride, when it is used in a greenhouse, it comes off at the end, but the fluorine resin film can maintain its structure. Further, it can be recycled. E: No dew condensation due to its heat insulating property. f: Holes do not open due to hail.
