BS EN 14932 Plastics - Thermoplastic stretch films for wrapping silage bales
BS EN 14932塑料.包装袋用伸缩热塑性薄膜.
BS EN 14932塑料.包装袋用伸缩热塑性薄膜—适用范围
Scope：
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.
