PLASTIC PLUGS

Postal Tube Plastic Plugs

Our high-quality postal tube plugs are available in six different sizes to fit a variety of internal diameters ranging from 38.1mm to 152.4mm. Our plug ends for postal tubes are designed and manufactured to fit perfectly within our postal tubes without causing any damage to the product enclosed inside.

If you require specific measurements, please get in touch with us to accommodate your request.

All of our tubes come with mailing tube caps; however, we sell them separately in case there is a scenario where you lose your existing cardboard tube end caps or if you wish to gain access to spares just in case.

At Postal Tube Shop, we are dedicated to customer satisfaction. We’ve made these mailing tube caps with you totally in mind, and we hope that shows.

What are plastic tube plugs used for?

They seal the cap of the postal tube completely and give the consumer extra protection from their product inside being damaged. Plastic plugs are the best option for your postal tube ends; they are secure and look professional when using postal tubes for business use.

Are you looking for a plastic-free alternative?

Tucked-end tubes are an innovation that will revolutionise the shipping of postal tubes.

They eliminate excess cardboard or plastic and still leave a tamper-proof seal, ensuring a secure delivery.
