scope:

This European Standard specifies the requirements for dimensional, mechanical and optical characteristics of stretch thermoplastic films for wrapping round bales used for outdoor ensiling of forage. This European Standard specifies classifications for durability and solar reflectance of stretch films for wrapping round bales. This European Standard specifies also test methods to check these requirements. This European Standard is applicable to white, black or coloured films based on polyethylene and/or ethylene copolymers. The range of film widths considered is from 250 mm up to 1 000 mm. NOTE - 6 layers of stretch films, pre stretched up to 80 %, should be used for wrapping round bales.
