It is particularly well suited to A3 documents, including oversized formats such as SRA3, giving extra clearance for easier rolling and insertion without damaging edges.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eManufactured 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eSupplied in packs of 25, with a pallet quantity of 1600 units. All tubes are delivered flat packed to reduce storage space and inbound transport costs.\u003c\/p\u003e\n\u003cp\u003eLooking for bespoke printed triangular postal tubes to promote your brand? \u003ca href=\"https:\/\/thepackagingclub.co.uk\/pages\/contact\"\u003eTalk to our sales team today.\u003c\/a\u003e\u003c\/p\u003e","brand":"The Packaging Club","offers":[{"title":"Pack 25 units","offer_id":42207262375991,"sku":"TPT-430-100-100-PACK","price":10.0,"currency_code":"GBP","in_stock":true},{"title":"Pallet 1600 units","offer_id":42207262408759,"sku":"TPT-430-100-100-PALLET","price":512.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/0704\/8759\/files\/Triangularpostaltubes_0004_TPT-430-100-100.jpg?v=1777901105","url":"https:\/\/thepackagingclub.co.uk\/products\/triangular-postal-tubes-a3-430-x-100-x-100mm","provider":"The Packaging Club","version":"1.0","type":"link"}
