Triangular Postal Tubes A0 950 x 142 x 142mm
Triangular Postal Tubes at Unbeatable Prices Strong kraft B flute corrugated board construction Triangular design prevents rolling during transit and storage Full length peel and seal strip with tuck-in end tabs Supplied flat packed for space-saving storage Also known as triangular postal boxes This large format triangular postal tube measures 950 x 142 x 142mm and is designed for securely posting A0, B1 and A1 documents, posters, plans and other long, rigid items. An A0 print rolls down to 841mm, leaving plenty of room to load and seal. The extended length and wider 142mm profile also allow for a looser roll, which helps protect edges, reduce curl memory and maintain print quality during transit. The triangular format, often referred to as a triangular postal box, creates reinforced edges and improved crush resistance compared with round tubes, while remaining lightweight for postal use. The larger profile also increases internal capacity, making it suitable for bulkier or multiple rolled items. Manufactured from high quality kraft B flute corrugated board, these tubes offer a consistent balance of rigidity and material weight. B flute refers to the corrugation profile, which is well suited to postal packaging where strength and presentation both matter. Once erected, the triangular shape helps prevent movement on conveyor systems and stops the tube rolling during handling. The roll-up design folds quickly along pre-creased panels and is secured using a full length peel and seal strip, removing the need for tape. Tuck-in end tabs add further security at each end, creating multiple layers of board where impact is most likely. Supplied in packs of 25, with a pallet quantity of 800 units. All tubes are delivered flat packed to reduce storage space and inbound transport costs. Looking for bespoke printed triangular postal tubes to promote your brand? Talk to our sales team today.
