松散填充材料可以用于对任意规格尺寸及形状的产品进行缓冲包装和固定，具有包装作业的方便性和适用性。松散填充材料的载荷能力、缓冲包装性能及对产品的固定作用，决定了这一材料的包装保护功能。通过对4种结构形状的松散填充材料在静态压缩、动态冲击和迁移性方面的测试与评价，分析了各种松散填充材料的包装性能，并与纸浆模制松散填充材料进行了比较，说明了松散填充材料单体结构形状对其缓冲性能和固定作用的影响。

Loose filling material has suitability and convenience in packing operation, and can be used for packaging of products with varied shape, size and dimension. Packaging protection function of the material is determined by its loading ability, cushioning packaging property, and the ability of proper securing products inside the container. Tests of static compression, dynamic impact, and degree of migration were carried out to four different types of loose filling material. The packaging properties of the loose filling materials were analyzed and compared with moulded pulp loose filling material. The influence of single unit structure and shape of loose filling material on cushioning property and securing function was explained.
