This standard concerns transparent and diffusing plastic films based on polyethylene and/or ethylene copolymers which are designed to be used as covers for permanent and temporary greenhouses for forcing and semi-forcing vegetable, fruit and flower crops.
This standard is intended to establish the basic requirements for the physical and mechanical characteristics of various types of film.
From a detailed consideration of the different covering plastics films used in agriculture and horticulture in the European market, different types of film are considered, according to the application, independently of the colour:
- normal film
- thermic clear film
- thermic diffusing film
The range of thicknesses considered is from 50 um up to more than 200 um.
