Laminate for packaging and package

Abstract

A packaging multilayer material 14 is formed by sequentially laying an air permeable heat-resistant fiber material layer 11 having a heat-resistance of not lower than 150° C., a polyethylene type resin spunbonded non-woven fabric layer 12 and a microporous film layer 13 in the above listed order by means of thermal bonding. The air permeable heat-resistant fiber material layer 11 is made of resin spunbonded non-woven fabric having a melting point between 150 and 300° C. and the polyethylene type resin spunbonded non-woven fabric layer 12 is an ethylene-α-olefin copolymer having a density between 880 and 950 kg/m 3 , while the microporous film layer 13 is made of polyethylene type resin.
