摘要: The invention provides a multi-layer film having a barrier layer of a thermoplastic material and on at least one side thereof a seal polymer derived of ethylene and an ethylenically unsaturated ester which is RF weldable in which the seal polymer has an anti-block matted surface. The film has barrier properties and can be used to package liquids in pouches.

摘要: Disposable liquid absorbent garments such as diapers having elastic grip regions comprise a liquid impervious outer layer, a liquid pervious inner liner and an intermediate absorbent layer. The outer layer is an elastomeric film blend of thermoplastic ethylene polymer and olefinic elastomer which is oriented except for local areas of reduced orientation and increased elasticity which constitute the grip regions.
