How to choose a film for a greenh
Every year the number of gardeners, agronomists and agro-industrial complexes who abandon polycarbonate and cheap polyethylene in favor of perennial greenhouse films grows. But how to choose the right film for a greenhouse? What to look for when buying? We will analyze it in our article.

What is the film made of?
The film market is quite extensive, so it is quite easy to get confused when choosing a greenhouse film. The first thing you should pay attention to is the material the film is made of. There are many types of materials for film production: polyethylene, metallocene polyethylene, EVA copolymer, etc.

Hydrophilicity
An important characteristic is hydrophilicity. This is the film's ability to attract water. If special additives for hydrophilicity are introduced during production, water vapor will condense on the film and turn into a uniform layer of water. The water will flow to the edges of the dome and soak into the ground. At the same time, the film retains its transparency and ability to transmit sunlight.
