A method of manufacturing an elastic film laminate includes stretching an elastic film in at least one direction at a first draw ratio, relaxing the elastic film, stretching the elastic film at least once more in the at least one direction at a second draw ratio less than the first draw ratio, and laminating the elastic film to at least one substrate web.

Methods for manufacturing elastic film laminates

Microporous breathable films include a polyolefin and an inorganic filler dispersed in the polyolefin. Methods for forming polymeric films and articles of manufacture prepared therefrom are described.

Microporous breathable film and method of making the microporous breathable film

A laminate sheet is formed from a lamination system that includes a sheet supply, a material supply, and a laminator. The laminator causes a sheet from the sheet supply to be laminated to a sheet from the material supply to establish the laminate sheet. The laminate sheet includes film strips and a web coupled to the film strips.

Laminate sheet

Gas-permeable barrier films include a polyolefin and an inorganic filler dispersed in the polyolefin. Methods for forming polymeric films and articles of manufacture prepared therefrom are described.

Stretched elastic films include a polyolefin, a styrene block copolymer, a non-styrene block copolymer, or a combination thereof. Methods for forming polymeric films and articles of manufacture prepared therefrom are described.

Prestretched elastic film in personal hygiene products

A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

Elastic non-woven lamination method and apparatus

A lamination system includes a sheet supply, a material supply, and a laminator. The laminator causes a sheet from the sheet supply to be laminated to a sheet from the material supply to establish a laminated sheet.

In-line lamination method and apparatus

Multi-layer films include at least one cavitated core layer that is microporous and breathable, and at least one skin layer. The cavitated core layer includes a polyolefin and an inorganic filler dispersed in the polyolefin. Methods for forming polymeric films and articles of manufacture prepared therefrom are described.

Polymeric films and methods for making polymeric films

A lamination system includes a film supply, a material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the material supply to establish a laminated sheet.

Methods and apparatus for transporting either an entire web or discrete components of disposable products such as diaper components down the machine using mechanical forces to grip the nonwoven web and transfer it from one belt or roll to another without or reducing added vacuum. There is a carrier nonwoven web that goes down the length of the machine and other substrates are added on top of this layer, and the machine provides sufficient gripping to allow transport of diaper components through the fabrication process. Securing and releasing forces are supplied so that the components can be retained at some points and released at others.

Apparatus and methods for transporting webs of material

Elastic laminates and methods of making same are provided, wherein the laminate includes an elastic film laminated to at least one substrate web, and wherein the elastic film has been stretched at least twice prior to bonding the film to the substrate layer. Such laminates possess improved bond strength between the film and the substrate web and have greater elongation versus laminates made with a film that has been stretched only once.

Elastic film laminates prepared by multiple stretching steps

A stretchable elastic laminate including at least one nonwoven fabric layer, and at least one elastomeric material extruded as a melt onto a major surface of the nonwoven fabric to form an elastic layer bonded to the surface of the nonwoven fabric. The nonwoven fabric layer has first and second bonding zones formed on the surface thereof, which have first and second bonding strengths. The elastic layer is bonded to the surface of the nonwoven fabric such that the elastic layer forms a stronger bond with the first bonding zone on the surface of the nonwoven than the bond formed between the elastic layer and the second bonding zone on the surface of the nonwoven. The lightly bonded areas of the elastic laminate provide increased elongation in the cross direction and improved recovery after stretch, while the more strongly bonded areas provide adhesive strength. Also disclosed is a method of forming a stretchable laminate having increased elongation and improved recovery after stretch.

Stretchable elastic laminate having increased CD elongation zones and method of production

The present invention relates to stretchable webs having a plurality of elongated cells, and a retractive force mechanism to provide increased retractive force of the web when stretched in a given direction. The stretchable webs are useful in disposable garments such as diapers, bandages and other hygiene material so that the material fits closely without slipping off.
