Abstract
A laminate (110) of polypropylene films (100), a luggage shell (120) constructed of the laminate (110), a method (200) of making the laminate (110), and a method (280) of making the luggage shell (120) are provided. The films (100) include a core (102) and at least one outer layer (104). The laminate (110) includes a plurality of films (100). The laminate (110) may be formed by laminating a plurality of films 100 under predetermined pressure, temperature, and time conditions. The shell (120) may be formed by deep drawing a sheet of laminate (110) while applying heat and tension to the laminate (110).
