Protect your products with our superior quality A3 Postal Tubes. This page on the site is designed to help you identify suitable postal tubes for A3 size paper. Though of course they can be used for other items.
 
Heavy Duty A3 Cardboard Postal Tubes
 
Strong Defenda A3 Postal Tubes. The most commonly used size Postal Tubes for A3 posters, artwork etc are 330mm long x 50mm diameter or 13″ x 2” in imperial size with a 1.5mm wall. These tubes provide a high degree of protection and a reasonable size diameter to prevent curling of the contents.
 
However, we offer A3 postal tubes in slightly longer lengths for oversized A3 items. We also produce them in narrow diameter and wider diameters.
 
38mm diameter A3 postal tubes are popular but their narrower diameter can lead to undesirable curling of the product. For those wishing to reduce curling to an absolute minimum our 3” & 4” diameter A3 cardboard postal tubes are an incredibly desirable option.
 
We manufacture in various wall thicknesses and hold stock of ‘Extra Strong’ Heavy Duty 2mm wall A3 postal tubes. We also produce cardboard A3 size postal tubes in an Extra Heavy Duty form with a 3mm wall for clients requiring greater levels of protection. Though these super strong tubes are held in smaller quantities.

Things To Consider When You Buy A0 Postal Tubes

When purchasing postal tubes for your A3 documents there are a couple of things to bear in mind to ensure your items are properly protected.

  1. A3 postal tube sizes are based on you rolling your documents on the short side, NOT lengthways.
  2. Always remember our postal tubes are manufactured slightly longer to allow a little extra length for the end caps to be pushed into the postal tubes… as you don’t want to crumple the edges of your A3 size documents when sealing your tubes.
  3. Where possible staple your caps or plugs in place to provide added security to your postal tube contents.
