Plastics - Thermoplastic stretch films for wrapping silage bales
Abstract
This document specifies the requirements for dimensional, mechanical, oxygen transmission rate and optical characteristics of thermoplastic stretch films for wrapping bales used for ensiling of forage. It specifies a measurement for solar reflectance of the films. This document specifies also test methods to check these requirements. This document is applicable to white, black, or coloured films based on polyethylene materials. It covers the width range from 250 mm up to 1 500 mm. The performances of the stretch films in conformance with this document 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 document also gives guidance for design for recycling.
