Strong A3, A2, A1 and A0 Triangular Postal Tubes Or Boxes In Standard Paper Sizes

Our DEFENDA standard paper size triangular tubes roughly equate to 50mm or 2” diameter or 76mm or 3” in our round tube range. We are planning to introduce a 100mm or 4” diameter triangular tube in the near future.

These triangular boxes are perfect substitute tubes for packing posters, prints, artwork, maps, decals or blueprints and are produced from recycled and fully recyclable material. The integral cardboard closures on our paper sized range will suit those wanting to avoid using plastic caps required for securely sealing round or circular postal tubes. Our 5" diameter tubes are produced with separate die cut caps which is particularly useful with the extra long versions which can be easily cut to length – providing a versatile option for shipping a range of long products.

As an eco-friendly product they tick all the boxes as they are constructed from corrugated paper board and can be recycled easily by placing in yours or your customer's recycle bin or simply be composted if convenient. They are made by us in the United Kingdom preventing unnecessary import miles being accrued.

Custom made triangular tubes can be manufactured quickly for customers requiring other sizes in terms of length or diameter. Simply contact us for more details.
