101mm ID mailing tubes, another popular size for poster tubes they are great for storing, transporting and retailing thousands of different products (inlcuding posters obviously!). The bigger the diameter of your tube the less the curl will be on any poster/photograph contained in the tube - this can be really important for some products.
Our customers have used them for photographs, invitations, maps, printing plates, film work, plans, hats, t shirts, extruded aluminium, pvc pipes........the list goes on and is only limited by your imagination. We've even had a customer use them to build a retail display in a store!
Our poster tubes are manufactured on site here in Manukau and are made from high quality, spiral wound cardboard with a 2.2mm wall thickness. This is a 33% thicker wall than the tubes you would get from the Post Office and increases the crush strength exponentially.
