Printing on Polyurethane (TPU) Envelopes – No problem!

April 01, 2018

Printing on Polyurethane (in further text TPU) is widely considered as “Black Art”. The reasons are deriving directly from the Polyurethane films properties - inability to affect the surface of TPU, and this is why it is so hard to prepare it for print. The molecular density of TPU is so dense that the surface is smooth as glass.

How is it possible to print on Blimps than?

On the other hand, this molecular density is perfect for small Blimps and Airships up to 20 m. Helium atom is the second smallest in size (after Hydrogen) and as such it escapes through all known materials and films.

The lowest permeability for above-mentioned sizes and Blimp types is TPU, as the helium permeability is the lowest possible. Our 20 years’ experience is that the helium permeability of TPU that we use in our production is 0.5 to 0.7% on total volume regardless per day.

Developing the technology and getting results

For the past 2 years we have worked hard on developing the technology which will enable us to print on TPU, without reducing the high quality of TPU for Blimp envelopes while making printing on TPU possible.

With high demand (logically) for colorful Blimps on a global level, both indoorand outdoor, the logical course of action was to enable our production line to brand blimps.
And the result is far better than we expected! Take a look for yourself.

Officially from now on we offer the possibility to our clients to print Logos, partially or entirely, on envelopes of all sizes - from 2 to 12 m or larger/longer.
