A3 Paper Storage Boxes

Large format paper is expensive, awkward to store, and easily damaged. A single ream of SRA3 specialist paper can cost significantly more than a standard A4 ream — and leaving it unsealed on a shelf risks moisture, dust, and edge damage that makes the top sheets unusable.

The WestonBoxes SRA3 storage box is a heavy-duty clear polypropylene box designed to hold a full ream of SRA3 (450 x 320mm) or A3 (297 x 420mm) paper flat, protected, and ready to use. Originally developed for commercial print rooms where expensive specialty papers need proper protection between runs.

Used by professional printers, reprographics departments, architects, artists, and anyone who regularly works with large format paper. Made from clear polypropylene at our Sunbury-on-Thames factory.
