Low porosity fibrous materials, articles formed therefrom and processes for their formation. Multiple plies of high tenacity, multifilament elongate bodies are optionally stitched together and pressed as a set without being laminated, adhered or thermally fused to each other. Pressing spreads the component filaments of the elongate bodies, forcing the filaments to occupy spaces between adjacent fibers and thereby reducing porosity of the complete multi-ply material.

A packaging material includes a metal foil layer laminated on an inner side of a substrate layer, a sealant layer laminated on an inner side of the metal foil layer, and a colored adhesive layer provided between the metal foil layer and the substrate layer. The colored adhesive layer contains a color pigment. The substrate layer is 2.0% to 5.0% both in the hot water shrinkage in a machine direction (MD) and the hot water shrinkage in a transverse direction (TD), 1.5% or less in the difference between the hot water shrinkage in the MD and the hot water shrinkage in the TD, 1.5 GPa to 3 GPa both in an elastic modulus in the MD and an elastic modulus in the TD, is 320 MPa or more in at least one of breaking strength in the MD and breaking strength in the TD.

This multilayer body is provided with a base layer, an intermediate layer, a heat seal layer, a first adhesive layer that is provided between the base layer and the intermediate layer, and a second adhesive layer that is provided between the intermediate layer and the heat seal layer. The base layer, the intermediate layer, and the heat seal layer are configured to include polyethylene. In a case where the base layer is a stretched polyethylene film, the intermediate layer is an unstretched polyethylene film, and in a case where the intermediate layer is a stretched polyethylene film, the base layer is an unstretched polyethylene film. The proportion of polyethylene in the multilayer body is 90% by mass or more.

Polyethylene compositions are disclosed that may have a density of 0.910 g/cm.sup.3 to 0.924 g/cm.sup.3 and a melt index (I.sub.2) In of 0.1 g/10 minutes to 0.5 g/10 minutes and include a first polyethylene fraction area in the temperature range from 45° C. to 80° C. of an elution profile via improved comonomer composition distribution (iCCD) analysis method; a second polyethylene fraction area in the temperature range from 80° C. to 95° C. of the elution profile, and a third polyethylene fraction area in the temperature range from 95° C. to 110° C. of the elution profile. The second polyethylene fraction area may include at least 5% of the total area of the elution profile. The third polyethylene fraction area may include at least 25% of the total area of the elution profile. A ratio of the first polyethylene fraction area to the second polyethylene fraction area may be from 6 to 15.
