Micro Bubble Film

Short Description:

Film made with very high EVA content to which is added an expander that creates within the film micro air bubbles that have the ability to spread light and greatly increase the IR barrier both in the entrance and the exit of the greenhouse


Product Detail

Product Tags

Special design for strong cooling purpose.

Film made with very high EVA content to which is added an expander that creates within the film micro air bubbles that have the ability to spread light and greatly increase the IR barrier both in the entrance and the exit of the greenhouse

By forming mic air bubble that produces an air-conditioning effect inside the greenhouse, lowering maximum temperatures during the warmest times of the year. it reduces stress on the plants caused by peak high temperatures, improving overall crop development.

In addition, these mic bubbles create strong light diffusing effect, which provides great uniformity in the incidence of visible radiation inside the greenhouse, generating an optimal atmosphere for plant growth.  It has a special UV stabilizers that protects against UV radiation, making the film highly resistant to degradation from both UV radiation and treatments applied inside greenhouses.

 

Main features:

Strength mechanical properties: 5-layer coextruded films has better structure.

High visible light transmission, which is required by the plants to assist in the photosynthesis and other related morphogenetic process.  

Very good heat-insulation effect: The effect of the EVA copolymers, together with the gas mic bubble in the film, create a barrier against IR radiation emitted by the soil at night, preventing sharp temperature drops (especially at night) and eliminating the risk of thermal inversion that could jeopardize plant life.

Highly resistant to degradation caused by sunlight and treatments applied inside the greenhouse.
