Our polythene is exclusively sourced from Sotrafa in Spain, the world’s biggest producer of horticultural film with an enviable reputation for quality thanks to exhaustive testing in the demanding weather conditions of Almeria.
First Tunnels are the sole distributor of Sotrafa products in the UK, and we are proud to work with the global leader to deliver the best possible products for our customers. UK suppliers make cheaper alternatives, but the quality simply doesn’t compare.
Although guaranteed for 5 years against its biggest threat of sunlight degradation, when fitted correctly, it is not uncommon to hear our polythene covers have lasted in excess of 10 years.

Sunlight is the biggest enemy of polythene. While it’s essential for the wellbeing of whatever you’re growing, it also ‘kills’ polythene in much the same way you can find old discarded crisp packets lose their colour and become very brittle. First Tunnels polythene covers are developed and tested in the extreme conditions to give optimum performance and are UV stabilised to prevent the polythene from breaking down prematurely.
What is a KLy?
A Kilo-Langley is the measure of Solar energy radiated in 1 year. It varies from a minimum of 60 KLy in the Polar regions to 120 KLy in warm regions, and to a maximum of 200 KLy in the African desert. Southern Spain receives about 140 KLy whereas the UK receives about half of that, just 78KLy.
Our Smart White polythene is 720 gauge/180 micron and made up of 3 layers for outstanding strength and performance.
Total Transmission of Visible Light
The amount of available light entering the polytunnel through the film. Measured as a percentage of total light.
Smart White = 65%
Diffusion
The scattering of direct light entering the polytunnel ensuring no shadows, so all plants receive equal light. Measured as a percentage of total light.
Smart White = N/A
Thermal Effect
A pocket of additives within the layers of the film that ensure and maintain a stable and optimum temperature within the polytunnel, especially during the night when it is colder.
Smart White = N/A
Strength at Break
The load on a tested sample when it breaks. This is expressed in Pascals or MPa.
Smart White = MD23/TD22
Elongation at Break
The strain on a tested sample when it stretches. This is also expressed in Pascals or MPa.
Smart White = MD630/TD770
Creep
As the weather changes becoming hotter or colder, so the Polythene expands and contracts. Creep is the terms used to express this.
Smart White = 5
Dart Test
A test to measure the impact strength on a test piece of plastic, using a weighted falling ‘dart’.
Smart White = 700
