Abstract:
The present invention provides a double-sided adhesive sheet with which non-adhesive printed matter such as an advertisement can be attached to an adherend as a display object without using a pressure-sensitive adhesive, or the like, wherein air remaining is unlikely to occur when the sheet is attached to the adherend. The present invention is an electrostatic adsorbable sheet which is laminated by means of electrostatic adsorption, a protective layer (B) comprising a dielectric film on at least one surface of a support layer (A) comprising a thermoplastic resin film having undergone charging treatment; and an electrostatic adsorbable sheet which is laminated by means of electrostatic adsorption, a protective layer (B) comprising a dielectric film having undergone charging treatment on at least one surface of a support layer (A) comprising a thermoplastic resin film.
Abstract:
An object of the present invention is to provide a low pressure loss filter having a high dust- and dirt-collecting capability and excellent workability and sustainability of collecting capability. The filter of the present invention is a filter having air channels formed using an electret sheet; a porosity of the electret sheet being from 1 to 70%; an air channel cross-sectional ratio of the filter being from 10 to 99%; and a volume charge density of the filter being from 10 to 5000 nC/cm3.
