Total polymers for industry and agriculture. Greenhouse Film

Lumicene Supertough® and EVA, the ideal combination for greenhouse film

The characteristics and requirements for greenhouses are increasingly demanding. The customer demands an increasingly durable product and more efficient for plants growth, while reducing time and waste to the minimum.

For this type of solutions, Total presents Lumicene Supertough® and EVA, two high quality options. With an excellent processing capacity and exceptional mechanical properties, Lumicene Supertough® and EVA are the ideal combination to simplify film structures and facilitate material supply.

Lumicene Supertough®

Developed to meet the demanding requirements, Lumicene® and Lumicene Supertough® are polyethylenes with a unique molecular design. The best option to simplify film structures and offer a more sustainable product without compromising on quality is Lumicene Supertough® due to its excellent processability and mechanical properties.

EVA

Total offers a wide range of EVA products with different percentages of vinyl acetate that help to achieve the right thermicity. In addition, a correct bubble stability in large extrusion lines is achieved due to the appropriate rheology of the products.

Lumicene Supertough® along with EVA products provides significant downgauging potential for Greenhouse Film.

Recommendations depending on application

Depending on the type of application, Total recommends using one product or another:

Mechanics and Optics: The best solution to improve the mechanical and optical capabilities is Total Lumicene® & Lumicene Supertough®.
Thermicity: EVA copolymers are the best alternative to achieve a correct thermicity.
Processability: To avoid any problem in lines with a high output, Total Lumicene Supertough® gives the best bubble stability to the product.
