Provided is a stretchable film having excellent stretchability, excellent air permeability, and an excellent deodorizing property. Also provided is an article including such stretchable film. A stretchable film of the present invention is a film having stretchability, and includes a deodorant. The stretchable film of the present invention is a film having stretchability, and has a deodorization efficiency for each of ammonia and hydrogen sulfide 3 hours after the start of a deodorization test, the deodorization efficiency being measured by a detector tube method, of 10% or more.

Stretchable film and article comprising same

Provided is a stretchable laminate that achieves both a weight reduction and an extension strength, and that can be stably produced. Also provided is an article including such stretchable laminate. The stretchable laminate of the present invention includes: an elastomer layer; and an olefin-based resin layer arranged on at least one side of the elastomer layer, wherein when a longitudinal direction of the stretchable laminate is defined as an MD direction and a direction perpendicular to the longitudinal direction is defined as a CD direction, a ratio [10% extension strength in MD direction (N/30 mm)]/[basis weight (gsm)] of the stretchable laminate is 0.14 (N/30 mm&#xb7;gsm) or more.

Stretchable laminate and article comprising same

Provided is a stretchable film having excellent stretchability and excellent air permeability. Also provided is an article including such stretchable film. The stretchable film of the present invention includes an olefin-based resin and a filler.

Stretchable film and product including same

Provided is a stretchable film that can prevent a delivery failure when delivered from a winding body. Also provided is a stretchable laminate including such stretchable film. Still also provided is an article including such stretchable laminate. The stretchable film of the present invention includes a laminated film of a plurality of elastomer layers, wherein the stretchable film includes an elastomer layer (A), an elastomer layer (B), and an elastomer layer (A) in the stated order, wherein the elastomer layer (A) and the elastomer layer (A) are provided as outer layers, and wherein each of the elastomer layer (A) and the elastomer layer (A) contains a fatty acid amide.

Stretchable film, stretchable laminate and article comprising same

Provided is a method of producing a layered article by which a sufficient production speed can be achieved, and preferably, a variation in fusion strength can be suppressed and hence a variation in product quality can be reduced. The method of producing a layered article of the present invention includes fusing at least part of a single-layer body or a laminate including at least one layer including a non-woven fabric of fiber having a fiber diameter of 100 &#x3bc;m or less through ultrasonic welding.

Method for producing layered article

The stretchable porous film of the present invention includes voids in a surface thereof, in which: the stretchable porous film has an air permeability measured with an Oken-type air permeability meter of less than 99,999 sec/100 cc; the stretchable porous film has such an extending direction that an air permeability measured with the Oken-type air permeability meter in a state in which the stretchable porous film is extended by 100% becomes less than 60,000 sec/100 cc; and the stretchable porous film has such a pulling direction that when, in a hysteresis test, the stretchable porous film is pulled from a width of 20 mm and an inter-chuck distance of 30 mm to an inter-chuck distance of 60 mm at a pulling speed of 50 mm/min and held for 1 minute, and then the pulling of the inter-chuck distance is released, a residual strain becomes 10 mm or less.

Elastic porous film and article

Provided is a stretchable laminate which has a sufficient holding ability in the case of being stretched to be bonded onto another material and is excellent in feeling of touch. Also provided is an article including such stretchable laminate. The stretchable laminate of the present invention is a stretchable laminate, including: an elastomer layer; and a non-woven fabric layer arranged on at least one side of the elastomer layer, the stretchable laminate including an elastic lane portion and a rigid lane portion, the rigid lane portion requiring a strength of from 1 N/20 mm to 7 N/20 mm for obtaining a 5% deformation amount.
