Abstract: A formed film with micro-cells and macro-cells or depressions may be disclosed. For example, the film may include a lands. Each of the lands may include micro-cells thereon. The micro-cells may have a first orientation. The film may further include macro-depressions adjacent to at least one respective land. Each of the macro depressions may include additional second micro-cells. Those additional micro-cells may have a second orientation. The second orientation includes an orientation that is an inverse of the first orientation (e.g., is in an opposite direction of the first orientation).
Abstract: A method of protecting a smooth surfaced substrate by a surface protection film that has improved high temperature peel force properties and low residue upon removal of the surface protection film from the smooth surfaced substrate.

Abstract: A three-dimensional film for use as a transfer layer in an absorbent article has a continuous surface and a discontinuous surface disposed generally parallel to and spaced from said continuous surface; both the continuous surface and the discontinuous surface have large scale apertures defined by sidewalls originating on the surface and extending outwardly therefrom and sized to permit acquisition of fluids by gravity, and optionally each surface also includes small scale apertures sized to acquire fluids by capillary action.
Abstract: Films (10) for use in protecting surfaces are disclosed and comprise at least one release layer (14) and optionally an adhesion layer (12) and/or an intermediate layer, the release layer (14) having a plurality of three-dimensional protrusions (13) that are either formed integral with the release layer or are discrete polymer beads applied to the release layer.

Abstract: A composite particularly suited for use as a transfer layer in an absorbent article has a first layer comprising a formed film having a plurality of capillary-sized apertured protuberances and a plurality of two-dimensional drains, and a second layer in intimate contact with an apertured end of said capillary-sized protuberances and spaced from the first layer in a z-direction, the second layer is either a three-dimensional apertured formed film or a nonwoven web. In embodiments where the second layer is a three-dimensional formed film, the film contains a plurality of capillary sized protuberances that are of smaller diameter compared to the protuberances in the first layer and optionally also contains a plurality of drains, which can be either two-dimensional or three-dimensional, or combinations thereof.

Abstract: Systems and methods for forming a vacuum formed, apertured film with micro-aberrations may be disclosed. For example, a polymer web such as a molten polymer web may be received at an engagement point between a screen with a positive aberration and a roller comprising a surface with a negative depression. The roller may have a diameter of no more than about 5.5 inches. A micro-aberration may be expanded, for example, on a land of the polymer web at the engagement point by inserting the positive aberration on the screen into the negative depression on the surface of the roller at a pressure of about 1.5 to about 3.5 pounds per linear inch (PLI). Additionally, one or more apertures are formed in the polymer web adjacent to a micro-aberration on a land.

Methods of making the forming screens are also disclosed.
Abstract: A three-dimensional film for use as an acquisition distribution layer in an absorbent article comprising a first surface with drains extending downward from the first surface, the drains being capable of transmitting fluid by gravity; and protrusions extending upward from the first surface to an upper surface with at least one capillary extending downward from the upper surface, the capillaries being capable of transmitting fluid in contact with the upper surface by capillary action. The drains rapidly transmit fluid through the film, particularly fluid that is dynamically-deposited. The capillaries transmit statically-retained fluid that is in contact with the upper surface of the protrusions.

Abstract: The present invention relates to absorbent articles and non-absorbent articles which comprise at least one improved double-sided soft and elastic material composite. The composites according to the invention may also be breathable. The composites are produced by incrementally stretching a laminate of an elastic layer between two non-elastic cloth-like layers. The non-elastic cloth-like layers tear during stretching such that the elasticity of the laminate after stretching is substantially the same as the elasticity of the film elastic layer.
