    摘要： 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.

    摘要： Novel thermoplastic sheet materials, absorbant articles formed therewith and method of producing such sheet materials are disclosed. The novel thermoplastic sheet materials are soft and pliable having a high modulus, high impact resistance and tear strengths and enhanced tape adhesion. The novel thermoplastic sheet materials are formed directly during a coextrusion process which may thereafter include an embossing step. The novel, coextruded thermoplastic sheet materials comprise a plurality of coextruded layers having high modulus outer layers for permitting pressure-sensitive adhesive tape-tab fasteners to be positioned and repositioned thereon without losing substantial tape adhesion therebetween or tearing the sheet materials following their original attachments. The outer layers are formed with a first thermoplastic polymer, such as a polypropylene, having an effective modulus to resist tearing, yielding and deformation upon detaching tape-tab fasteners therefrom, and further having an effective bonding affinity to maintain tape adhesion after initial attachment. The other layer of the thermoplastic sheet materials is an inner layer(s) being formed with a second thermoplastic polymer, such as a polyethylene, to impart softness or low stiffness and effective impact resistance and tear strengths to the sheet materials. The novel thermoplastic sheet materials of the instant invention are suitable for use with articles which, for example, absorb body fluids, and are especially suitable for use as backsheet films in disposable diapers.

    摘要： A plastic film having a random embossed matte finish is provided. The random embossed matte film may be wound very easily into rolls and the roll contour achieved has superior uniformity. In addition, the film provides relatively equal tape adhesion and gloss properties on both sides which make it especially suitable for use in articles such as disposable diapers or underpads. Another advantageous property which renders it especially suitable for diaper conversion operations is its very low degree of edge curl. The thin film provides a totally different appearance as compared to conventional diaper films in that the overall appearance is a dull matte finish, but nonetheless having slight sparkles of brilliance throughout the surface, and it further provides a softer feel.

    摘要： 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.
