Composite layer

A composite layer comprising:

• a first plurality of longitudinal, generally parallel first zones comprised of a first polymeric material each encapsulated in a second polymeric material, wherein there are at least 10 longitudinal first zones per cm, wherein each first zone has a center point, wherein there is a length between two center points separated by a second zone, and wherein there is an average of said lengths;
• and
• a second plurality of longitudinal, generally parallel first zones comprised of the first polymeric material each encapsulated in the second polymeric material, wherein there are at least 10 longitudinal first zones per cm wherein there is a length between two center points separated by a second zone, and wherein there is an average of said lengths,
• wherein there is an average length two center points separated by a second zone for the composite layer of the average of said averages lengths two center points separated by a second zone for the first and second pluralities, and wherein there is a third zone comprising the first or second polymeric material separating the first and second pluralities having a width wider than said average length two center points separated by a second zone for the composite layer.
