Strong A3 Triangular Postal Tubes For Pictures & Posters

370mm long x 57mm diameter triangular postal tubes

Whether you are posting A3 prints, posters, maps, blueprints or even original paintings, these great quality triangular tubes offer a fabulous shipping solution. The triangular design renders them anti-roll when it comes to passing through modern sortation systems used by all the major carriers and therefore exempt from manual handling surcharges levied by many of them.

They are extremely eco-friendly as they are manufactured by us here in the UK avoiding needless product miles being clocked up through importing from across the globe. They are made from recycled and 100% recyclable material further enhancing their environmentally friendly credentials. The integral corrugated caps avoid the need to use plastic caps as stoppers and are therefore ideal for clients intent on removing plastic from their packaging processes.

We have produced all of our triangular tubes with extra space which allows them to be used in conjunction with our range of normal paper size tubes where clients wish to utilise them as outers in which to insert either our standard, extra strong or super strong extra heavy duty circular / round postal tubes. These strong A3 triangular tubes are perfect for protecting documents and other items and can even be used as outers for our 2" diameter A3 size round tubes creating an anti-roll product which is courier friendly and likely to attract reduced shipping charges. Speak to your parcel rep about discounted shipping.

All triangular postal tubes are delivered flat packed for easy and efficient storage and can be assembled easily using the locking tabs with kraft paper or a glue gun to secure them prior to shipping.

The triangular design is ideal for customers wanting to pre-pack them with posters etc as they can be stored on shelving without rolling off.

*All of our standard paper size triangular tubes are printed with information about their manufacture, recycling and composition.*
