Claims
- 1. An antimicrobial laminate characterized by having a substratal film impervious to steam and a film pervious to steam superposed through the medium of an intermediate layer containing an allylisothiocyanate (AITC) inclusion cyclodextrin compound wherein said film pervious to steam possesses permeability to steam (JIS {Japanese Industrial Standard} Z 0208) in the range of from 5 to 40 4/m.sup.2 .multidot.24 hr;
- wherein said film pervious to steam consists of numerous minute depressions formed therein in a thickness direction of said film to the middle part of the film in said thickness direction from a surface and not extending through said film in said thickness direction.
- 2. The antimicrobial laminate according to claim 1, wherein said intermediate layer is an adhesive agent layer containing an AITC inclusion cyclodextrin compound.
- 3. The antimicrobial laminate according to claim 1, wherein said substratal film is provided on one side thereof with a gas-barriering layer and said intermediate layer is interposed between said gas-barriering layer and said film pervious to steam.
- 4. An antimicrobial laminate characterized by having superposed a substratal film impervious to steam and an antimicrobial film provided with an allylisothiocyanate (AITC) regenerating layer containing an AITC inclusion cyclodextrin compound and said antimicrobial film being formed by alternately superposing AITC regenerating layers and films pervious to steam and consequently provided with two or more AITC regenerating layers, wherein said permeability to steam of said steam-pervious film (JIS {Japanese Industrial Standard} Z 0208) is in the range of from 5 to 40 g/m.sup.2 .multidot.24 hr, and
- wherein said film pervious to steam superposed in the outermost layer on the side opposite said substratal film consists of numerous minute depressions formed therein in a thickness direction of said film to the middle part of the film in said thickness direction from a surface and not extending through said film in said thickness direction.
- 5. The antimicrobial laminate according to claim 4, wherein the outermost layer on the side opposite said substratal film is formed of said steam-pervious film and all the AITC regenerating layers are each formed of an adhesive agent layer containing an AITC inclusion cyclodextrin compound.
- 6. The antimicrobial laminate according to claim 4, wherein said substratal film is provided on one side thereof with a gas-barriering layer and said AITC regenerating layer is interposed between said gas-barriering layer and said film pervious to steam.
- 7. An antimicrobial laminate characterized by having superposed a substratal film impervious to steam and an antimicrobial film provided with an allylisothiocyanate (AITC) regenerating layer containing an AITC inclusion cyclodextrin compound and said antimicrobial film being formed by interposing between two vertically opposed AITC regenerating layers a steam-pervious film having a hygroscopic powder dispersed therein, and
- wherein said film pervious to steam superposed in the outermost layer on the side opposite said substatal film consists of numerous minute depressions formed therein in a thickness direction of said film to the middle part of the film in said thickness direction from a surface and not extending through said film in said thickness direction.
- 8. The antimicrobial laminate according to claim 7 wherein said permeability to steam of said steam-pervious film (JIS Z 0208) is in the range of from 5 to 40 g/m.sup.2 .multidot.24 hr.
- 9. The antimicrobial laminate according to claim 7, wherein said substratal film is provided on one side thereof with a gas barrier layer, said AITC regenerating layer is used as an adhesive layer, said antimicrobial film is formed by sequentially superposing an AITC regenerating layer, a steam-pervious film having a hygroscopic powder dispersed therein, an AITC regenerating layer, and a steam-pervious film containing no hygroscopic powder in the order mentioned, and said gas barriering layer of said substratal film and said AITC regenerating layer of said antimicrobial film are superposed.
