    • A packaging material and method for making the same are disclosed. The packaging material includes a strength layer and image layer. The strength layer has two opposed surfaces. The strength layer includes softwood fibers having an average length ranging from about 1.5 mm to about 3.0 mm. The softwood fibers present in an amount ranging from about 70 wt % to about 100 wt % of a total wt % of the strength layer. The image layer includes hardwood fibers having an average length ranging from about 0.5 mm to about 1.5 mm. The hardwood fibers present in an amount ranging from about 70 wt % to about 100 wt % of a total wt % of the image layer. The image layer includes a water soluble di-valent or multi-valent salt present in an amount ranging from about 5 lb per ton of total fibers in the image layer to about 50 lb per ton of the total fibers in the image layer.
    • 公开了一种包装材料及其制造方法。 包装材料包括强度层和图像层。 强度层具有两个相对的表面。 强度层包括平均长度为约1.5mm至约3.0mm的软木纤维。 软木纤维的存在量为强度层总重量%的约70重量%至约100重量%。 图像层包括平均长度为约0.5mm至约1.5mm的硬木纤维。 硬木纤维的存在量为图像层的总重量%的约70重量%至约100重量%。 图像层包括以图像层中每吨总纤维约5磅至图像层中每吨总纤维约50磅的量存在的水溶性二价或多价盐。
