BS EN 14932塑料.包裝袋用伸縮熱塑性薄膜—標準名稱
BS EN 14932 Plastics - Thermoplastic stretch films for wrapping silage bales
BS EN 14932塑料.包裝袋用伸縮熱塑性薄膜.
BS EN 14932塑料.包裝袋用伸縮熱塑性薄膜—適用范圍
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.
