摘要

A wrapping material for light-sensitive materials comprising at least two monoaxially drawn films composed of high density polyethylene having a density of at least 0.94 g/cm3, which are bonded with an adhesive layer containing an aluminium paste or an aluminium powder so that drawing axes of the films cross each other at an angle of from 45 DEG to 90 DEG .
