Specifically, the component “Multi-microlayer” refers to an film having a plurality of alternating microlayers wherein, based upon the process at which the film is formed, where each microlayer becomes partially integrated or adhered with the microlayers arranged above and below the microlayer.
Additionally, during formation of the films, which may include stretching, the microlayers will partially delaminate from one another, thereby permitting the corrugations to be formed upon relaxation or activation of the film. However, partial integration or adherence of microlayers remains, unlike certain prior multi-layer films. The system of this invention includes a plurality of corrugated microlayered films, which may be corrugated in a machine direction and/or a cross-direction to form micro channel spaces. Alternatively, some or all of the microlayers may be biodegradable. The microlayered films may contain particulate filler material, which upon stretching of the film may provide porosity initiating sites.
For example, an method for making the microlayer films of the present invention is a microlayer coextrusion process wherein two or more polymers (e.g., polypropylene for the extensible microlayer and polyurethane for the elastomeric microlayer) are coextruded to form a laminate unit with two or more microlayers, which laminate unit can then be manipulated to multiply the number of layers in the film.
