Abstract
The present invention is directed to a method for packing an article comprising providing a vapor permeable and substantially water impermeable composite laminated sheet comprising a nonwoven layer and a polymer film layer, said composite laminated sheet having a trapezoidal tear strength of at least about 2 N in the machine direction, and a smoothness measured on the polymer film layer of less than 9 micrometers and placing the composite laminated sheet on the surface of the article with the polymer film layer contacting at least a portion of said surface.
Claims28
A method for packing an article comprising:
- providing a vapor permeable and substantially water impermeable composite laminated sheet comprising a nonwoven layer and a polymer film layer, said composite laminated sheet having a trapezoidal tear strength of at least about 2 N in the machine direction, and a smoothness measured on the polymer film layer of less than 9 micrometers;
- and
- placing the composite laminated sheet on the surface of the article with the polymer film layer contacting at least a portion of said surface.
The method according to claim 11, wherein said cushioning material is a nonwoven bulky composite laminated sheet.
A protective cover for packing an article comprising a vapor permeable and substantially water impermeable composite laminated sheet comprising a nonwoven layer and a polymer film layer, said composite laminated sheet having a trapezoidal tear strength of at least about 2 N in the machine direction, and a smoothness measured on the polymer film layer of less than 9 micrometers.
A vapor permeable, water impermeable composite laminated sheet comprising a first layer of polymer film bonded to a second layer of powder-bonded nonwoven web, wherein said polymer film is a monolithic extrudate.
A vapor permeable, water impermeable composite laminated sheet comprising a first layer of copolyether ester film and a second layer of powder-bonded polyester nonwoven web.
A vapor permeable, water impermeable composite laminated sheet consisting of a first layer of microporous polymer film bonded to a second layer of powder-bonded nonwoven web and optionally a cushioning layer.
