    Abstract: An improved barrier cuff for disposable absorbent articles such as a diaper is disclosed. A diaper has a liquid-pervious liner, a liquid-impervious backsheet, and an absorbent core disposed between the liner and backsheet, and elastically contractible leg cuffs. The cuff has a proximal edge and a distal edge and is disposed adjacent margins of the disposable diaper and defines a waste containment pocket with the backsheet and liner frontsheet. The cuff being made of an embossed plastic film having a pattern of stretched and unstretched regions. The plastic film provides ultrasoft cloth-like and quiet material for use as a cuff in comparison to known plastic film or laminates. Leakage prevention and comfort to the user are increased because the body exudates are less capable of leaking out of the absorbent article prior to absorption into the core and the wearing comfort is provided by the ultrasoft cuff.

    Abstract translation: 公开了一种用于一次性吸收制品例如尿布的改进的阻挡箍。 尿布具有透液性衬垫，不透液体的底片和设置在衬垫和底片之间的吸收芯和弹性收缩的腿箍。 袖带具有近侧边缘和远侧边缘，并且设置在一次性尿布的边缘附近并且限定具有底片和衬里前端片的废物容纳口袋。 袖带由具有拉伸和未拉伸区域图案的压花塑料薄膜制成。 与已知的塑料薄膜或层压板相比，该塑料薄膜提供了超柔软的布状和安静的材料，用作袖口。 增加了对使用者的泄漏防止和舒适性，因为身体渗出物在被吸收到芯中之前能够从吸收制品中泄漏的能力较差，并且穿戴舒适性由超软袋提供。

    Abstract: Novel thermoplastic sheet materials for permitting positionable and repeated repositionable use of tape fasteners therewith without experiencing substnatial loss of tape adhesion therebetween are disclosed. A novel thermoplastic sheet material generally comprises an ethylene polymer and an anti-popoff polymer in an effective amount for increasing and substantially maintaining the tape adhesion. The increase in and substantial maintenance of the tape adhesion is accomplished without adversely affecting the properties or cost of the thermoplastic sheet material. A preferred formulation for producing the novel thermoplastic sheet material comprises polyethylene as the ethylene polymer and a polypropylene or alpha-methyl styrene as the anti-popoff polymer. The novel thermoplastic sheet materials are especially suitable for use as films which can be used as backsheets in absorbent articles, such as, disposable diapers, bandages, surgical dressings or drapes and catamenial pads.

    Abstract: Novel, unstretched synthetic papers being virtually free of mechanically produced microvoids and having a porous surface for writing and printing thereon are disclosed. The unstretched synthetic papers of the instant invention are formed typically by extruding from pellets a film or sheet material formed with a continuous olefin resin matrix containing an effective amount of a particulate filler having pre-existing microvoids inherent thereto, such as a diatamaceous earth. The microvoid particulate filler is dispersed somewhat uniformly yet randomly throughout the continuous olefin resin matrix of the unstretched synthetic papers to provide non-mechanically produced microvoids in communication with the surfaces of the unstretched synthetic papers to render said surfaces porous for imparting writeability and printability thereto. Additional paper-like characteristics can be imparted to the novel, unstretched synthetic papers of the instant invention by the addition of other resins, such as a styrene resin, to the continuous olefin resin matrix. The novel, unstretched synthetic papers of the present invention have good receptivity and retentivity for common writing materials, such as ink, pencil lead, paint and the like, even though they are not mechanically stretched to form mechanically produced microvoids.
