The present invention relates to a luggage, having an integrated structure. The luggage includes a one-piece shell, which is constructed from a single molding to form a continuous structure and has at least a top wall and two opposing side walls. The top wall has two sloping curved corners which are sloped and curved toward the cover of the luggage and the respectively abutting side wall. The present also invention provides a method of manufacturing the luggage. The method includes the steps of assembling a family mold to form a mold cavity, injecting mold material into the mold cavity to make the one-piece shell for the luggage, and removing the family mold. The family mold includes an inner mold tool and an outer mold tool, and the step of removing the family mold includes the steps of removing the outer mold tool first, and then, removing the inner mold tool.

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).

An article of luggage is provided for comprising a first layer of hard shell and a second layer of hard shell material with one or more ornamental substrate disposed between at least the first layer of hard shell material and at least the second layer of hard shell material. A section of hard shell material may be formed by pressing and/or heating at least the first layer of hard shell material, the second layer of hard shell material, and the ornamental substrate together.
