摘要
Field of the Invention The present invention relates to an expansive spacer film heater for increasing the lifetime of the wrapping foils (7,8), for securing the tightness of the foil (7, 8), and for increasing the thermal insulation capacity of the dowel-walled film housings. The non-absorbent sponge-like spacer (6) has two, preferably rounded, filtering elements (1), and these filtering elements (1) are attached directly to each other, either directly or by a fastener (5). The filter element (1) is a solid or hollow crimp film. The sum of the largest characteristic size (2) of a filter element (1) is at least a stone, the largest characteristic size (4) of the film transverse element (3). ŕ
