Abstract: A transportation system with a roll of material having an unsecured material portion is disclosed. The transportation system includes a first roller and a second roller spaced apart from the first roller. The spacing between the first roller and the second roller define a cradle. The cradle is operable to receive the roll of material, the roll of material having the unsecured material portion. At least one of the first roller and the second roller is rotatable about its axis to facilitate a securing of the unsecured material portion of the roll of material.

Abstract: A nonoriented film containing highly crystalline polypropylene, standard polypropylene and nucleating agents. The film has physical properties that are desirable for applications such as food wrappers and tampon overwrap, including good tearability, stiffness and memory. In addition, the nonoriented film is cost effective because the film achieves these physical properties without the step of stretching or orienting the film, as required for conventional polypropylene films used in food wrappers and tampon overwrap.

Abstract: The present invention comprises a stretched, multilayer breathable film that provides a barrier to microorganisms, blood and bodily fluids that is manufactured by simultaneously extruding a five-layer film having a minimum structure of C:A:B:A:C or a three-layer film having a minimum structure of C:D:C in which B is a microporous core layer, C is an outer monolithic layer, A is a microporous adhesive layer for bonding the outer monolithic layers to the core layer, and D is a microporous adhesive layer, and then stretching the extruded film to form micropores in the microporous core layer or the microporous adhesive layer, the micropores allowing the passage of water vapor but substantially preventing the passage of liquid water.
