Flat Boxes

NuPack Packaging’s flat pack boxes are the ideal solution for shipping smaller items while maintaining the reliability of more robust packaging options. These flat boxes are perfect for slim items like mobile phones, books, and DVDs.

Constructed from lightweight single-wall cardboard, these boxes feature a pristine white finish that is perfect for branding, printing, or decorating. You can write directly on them or attach an address label for shipping with a courier or through Australia Post. These flat boxes include a convenient self-locking tab to ensure contents are securely enclosed. They maintain their shape and won’t bend or roll. For added security, pair them with our corrugated paper roll.
