POROUS SHEET

摘要

A porous sheet obtained by melt-casting a resin composition containing an aliphatic polyester resin, a filler, and a plasticizer into sheet and stretching the sheet at least uniaxially. The filler is present in an amount of 20 to 300 parts by weight per 100 parts by weight of the aliphatic polyester resin. The plasticizer is a compound having two or more ester groups per molecule and being added an average of 3 to 9 moles of ethylene oxide per molecule. The plasticizer is present in an amount of 1 to 100 parts by weight per 100 parts by weight of the aliphatic polyester resin.
