Document Type and Number:
WIPO Patent Application WO/2020/085301
Kind Code:
A1
Abstract:
This filter for filtering comprises a first welding frame, a second welding frame, and a filter sandwiched between and welded to the first welding frame and the second welding frame. The first welding frame and the second welding frame are formed of a flexible film at least 120 µm thick. Moreover, the filter is formed from a substance with a melting point higher than that of the first welding frame and the second welding frame and has a porosity of 10–80%. Furthermore, the first welding frame is formed from high-density polyethylene with a melting point of 120–140°C, linear low-density polyethylene with a melting point of 105–125°C, or a mixture that includes at least the high-density polyethylene or the linear low-density polyethylene.
