Abstract

A package of a heat-bent polarizing sheet for producing an injection-molded polarizing lens and an injection-molded polarizing lens that uses said sheet is provided. The heat-bent polarizing sheet is cumulatively packaged by a non-adhesive isolation film so as to withstand moisture and then stored or transported and can be used in injection molding without performing preliminary drying as a pretreatment of injection molding and without substantial protective-film removal work.
