Plastics. Thermoplastic stretch films for wrapping silage bales
Soveltamisala
Suomenkielistä soveltamisalaa ei ole saatavissa.
This European Standard specifies the requirements for dimensional, mechanical, oxygen transmission rate and optical characteristics of stretch thermoplastic films for wrapping bales used for ensilaging of forage. It specifies a classification for solar reflectance of the films.
This European Standard specifies also test methods to check these requirements.
It specifies also test methods for the determination of the airtightness and oxygen permeability determined on a wrapped artificial bale.
This European Standard is applicable to white, black or coloured films based on polyolefin materials. It covers the width range from 250 mm up to 1 000 mm.
The performances of the stretch films in conformance with this European Standard are based on the use of at least six layers of films, pre-stretched at a ratio between 60 % and 70 % for round bales and a ratio of 55 % and 65 % for wrapping square bales.
This European Standard also gives guidance for storage of rolls and instructions for wrapping, storage of wrapped bales and for disposal of films.
