Abstract: A biodegradable breathable film is formed by mixing a biodegradable polymer with a particulate filler, forming the mixture into a film, and stretching the film uniaxially or biaxially to cause voids to form around the filler particles. The film may be laminated to a fibrous nonwoven web to form a laminate, and the fibrous nonwoven web may also be formed from a biodegradable polymer. The biodegradable film and laminate are useful in a wide variety of disposable personal care absorbent articles and disposable medical articles.

Abstract: A film that comprises a thermoplastic composition that contains a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains is provided. The film is biaxially stretched in a machine direction and cross-machine direction to form a porous network in the composition. The porous network contains nanopores having a maximum cross-sectional dimension of about 800 nanometers or less. At least a portion of the nanopores are oriented in the cross-machine direction so that the axial dimension generally extends in the cross-machine direction and the cross-sectional dimension generally extends in the machine direction.

Abstract: Se proporciona una estructura de construcción que contiene una envoltura de construcción que define un interior. La estructura de construcción incluye un aislamiento para construcciones ubicado adyacente a una superficie de la envoltura de construcción, el interior, o una combinación de estos. El aislamiento para construcciones puede incluir un material polimérico poroso que se forma a partir de una composición termoplástica que contiene una fase continua que incluye un polímero de matriz. Dentro de la fase continua pueden dispersarse un aditivo de microinclusión y un aditivo de nanoinclusión en la forma de dominios discontinuos, en donde se define una red porosa en el material que incluye una pluralidad de nanoporos que tienen una dimensión de la sección transversal promedio de aproximadamente 800 nanómetros o menos.

Abstract: An elastic laminate capable of being rolled for storage and unwound from a roll when needed for use, includes an elastic layer selected from the group consisting of an array of continuous filament strands, an array of continuous filament strands with meltblown deposited on the continuous filament strands, and a film; and a facing layer bonded to only one side of the elastic layer. The laminate may also include an adhesive that demonstrates a relatively short open time deposited between the elastic layer and facing layer, or such adhesive and a postbonding adhesive or nonblocking agent, or a nonblocking agent layer deposited on the elastic layer on a side opposite to the facing layer. The meltblown layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. The laminate suitably has an inter-layer peel strength of less than about 70 grams per 3 inches cross-directional width at a strain rate of 300 mm/min. Alternatively or additionally, the continuous filament strands and/or the facing layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. In certain embodiments, the elastic laminate may include an extensible facing layer bonded to an elastic or semi-elastic film layer having a basis weight of about 50 gsm or less, wherein the facing layer includes an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%.

Abstract: A breathable film having a base layer comprising first filler particles and second filler particles dispersed within a biodegradable polymer matrix is provided. The first filler particles constitute from about 25 wt. % to about 75 wt. % of the base layer and the second filler particles constitute from about 0.1 wt. % to about 10 wt. % of the base layer. The ratio of the average size of the first filler particles to the average size of the second filler particles being from about 2 to about 100. The film exhibits a water vapor transmission rate of about 2,000 g/m2/24 hours or more and a peak load in the machine direction of about 800 grams-force per inch or more.
