摘要： The article includes at least a first layer having first and second major surfaces and a second layer adjacent the second major surface of the first layer. The first major surface of the first layer is at least a portion of a visible, outer surface of the article. At least a portion of the first layer is a see-through thermoplastic film that has a first color other than white. The second layer includes a microporous film having an opaque, microporous region and a nonporous region. When the opaque, microporous region and the nonporous region are seen through the first layer, they create an appearance on the outer surface of two different colors or two different shades of the same color. A method of making the article is also described.

摘要： The article includes a thermoplastic layer having opposing first and second side edges and a first surface bearing male fastening elements. The thermoplastic layer is plastically deformed and has a retardance profile having an average retardance along a line from the first edge to a location 500 micrometers from the first edge and a distance from the first edge where 75% of the average retardance is observed of at least 10 micrometers. In some cases, a distance between the first and second side edges is up to 50 millimeters. In some cases, the article is a fastening tab. The method includes providing a thermoplastic film having opposing first and second side edges, with a distance between the opposing side edges of up to 50 millimeters, and stretching the thermoplastic film to form the thermoplastic layer, which is plastically deformed. The first surface of the thermoplastic film bears male fastening elements.

摘要： A fastening tape, mechanical fastener, methods of making them, and personal hygiene articles including them are disclosed. The fastening tape includes a tape backing having a fastening portion, an adhesive disposed on the fastening portion, and a release surface for the adhesive. The release surface is a either a release tape attached along one of its edges to the tape backing or a release coating disposed on at least a portion of a surface of the tape backing. At least one of the tape backing or the release surface comprises a microporous film having an opaque, microporous region and at least one see-through region of lower porosity within the opaque, microporous region. The mechanical fastener includes such a microporous film and mechanical fastening elements on at least one surface. The at least one see-through region extends through the thickness of the microporous film.

摘要： A laminate of an at least partially reticulated thermoplastic film joined to an extensible carrier. The reticulated thermoplastic film includes a backing with openings and discrete elements protruding from the first major surface. There are two discrete elements aligned in a first direction abutting opposite ends of any given opening. In a second direction perpendicular to the first direction, there is one discrete element between the given opening and an adjacent opening aligned in the second direction. Each portion of the thermoplastic backing around the given opening is plastically deformed in its lengthwise direction. A method of making a laminate is also disclosed. The method includes stretching a thermoplastic backing having a plurality of discrete elements in the first direction and laminating the backing to an extensible carrier. Subsequently stretching the laminate in a second direction forms a tear in the thermoplastic backing between two adjacent of the discrete elements.

摘要： A reticulated thermoplastic film includes a backing with openings and discrete elements protruding from the first major surface. There are two discrete elements aligned in a first direction abutting opposite ends of any given opening. In a second direction perpendicular to the first direction, there is one discrete element between the given opening and an adjacent opening aligned in the second direction. Each portion of the backing around the given opening is plastically deformed in its lengthwise direction and typically has higher stretch-induced molecular orientation at its edge adjacent the given opening than at its midpoint. The openings are often retractable. A method of making a reticulated thermoplastic film is also disclosed. The method includes stretching a thermoplastic backing with a plurality of discrete elements in the first direction. Subsequently stretching the backing in the second direction forms a tear in the backing between two adjacent discrete elements.

摘要： A personal hygiene article includes a chassis with a topsheet, a backsheet, and an absorbent component between the topsheet and the backsheet. At least one portion of the personal hygiene article includes a microporous film having an opaque, microporous region and at least one see-through region of lower porosity within the opaque, microporous region. The microporous film can include a beta-nucleating agent or can have thermally induced phase separation caused by a diluent. A container includes a microporous film enclosing at least one personal hygiene article. The microporous film has an opaque, microporous region and at least one see-through region of lower porosity forming a window within the opaque, microporous region. Methods of making the personal hygiene article and container are also described.

摘要翻译： 网状热塑性膜包括具有开口的背衬和从第一主表面突出的分立元件。 有两个离散的元件在第一方向上对齐，与第一个方向相抵接。 在垂直于第一方向的第二方向上，在给定开口和在第二方向上对齐的相邻开口之间存在一个分立元件。 围绕给定开口的背衬的每个部分在其长度方向上塑性变形，并且在与其中点相邻的给定开口的边缘处通常具有较高的拉伸诱导分子取向。 开口通常可伸缩。 还公开了一种制备网状热塑性薄膜的方法。 该方法包括在第一方向上用多个离散元件拉伸热塑性背衬。 随后在第二方向上拉伸背衬在两个相邻离散元件之间的背衬中形成撕裂。
