Looking for a postal tube that’s plastic-free from end to end, not just the cardboard body? Our cardboard plug postal tubes use a fully plastic-free plug instead of a standard plastic end cap, so the whole tube, including the closure, is recyclable. This is the same plastic-free construction used across our Recap range, available in every standard size from A0 to B2.

Cardboard Plug vs Plastic Plug: What’s the Difference?

Most postal tubes, including our own standard plastic plugs, use a moulded plastic component to seal each end. It’s durable and low-cost, but it’s the one part of an otherwise fully recyclable cardboard tube that typically can’t go in standard recycling.
A cardboard plug replaces that plastic component with a plastic-free material engineered to hold the same seal and grip, so the tube can be recycled as a single, plastic-free unit. It’s a straightforward swap if plastic-free packaging is a requirement for your business, your clients, or upcoming packaging regulations, without changing how the tube performs in transit.

Shop Cardboard Plug Tubes By Size
