An erosion control mat having buoyant fronds is deployed in a body of water to enhance the accumulation of sediments. The mat includes a plurality of frond lines arranged in a fanfold pattern. Each frond line include a continuous elongate strip and a plurality of side-by-side buoyant fronds (strands). The frond lines are made of linear low density polyethylene (LLDPE), preferably metallocene catalyzed LLDPE.

Erosion control mats

A polymer film comprising at least first and second contiguous and coextruded portions, wherein the first portion is extruded from a first polymer composition containing a filler material in an amount sufficient to increase the water vapor permeability of the first portion relative to the second portion, and the second portion is extruded from a second polymer composition such that a tensile strength of the second portion is greater than the tensile strength of the first portion. Such polymer films allow for highly vapor permeability, while providing portions with sufficient strength to allow for taping or attachment of fastening devices.

Breathable extruded polymer films

A disposable diaper having an elastic waist is provided with a foam strip to cushion stresses of the elastic band in the waist area.
