ある。 However, this microporous film cannot be heat-sealed when using a normal packaging machine that heats and presses the film from the outside because the film is fused to the heat bar or heat roll. Required special sealer. When such a special sealer is used, it is impossible to perform high-speed filling and packaging as in the past, and one has to be prepared for a significant drop in efficiency. In addition, most of the microporous membranes have weak packaging strength, and although they have sufficient air permeability to package the contents, most of them cannot be put to practical use due to insufficient packaging strength. It is.
