Naturally degradable and recyclable static-dissipative packaging material

A multiple-ply packaging material comprising:

• a layer of relatively rigid material having first and second surfaces;
• a film of amine free permanently static-dissipative material applied to one of said first and second surfaces, said film having a surface resistivity of more than 10.sup.5 but less than 10.sup.12 ohms per square, said film being applied to the layer of relatively rigid material while in a solid state, and the film having the same solid, amine-free permanently static dissipative characteristics before and after said applying, said layer and said film being naturally degradable.

A multiple-ply packaging material comprising:

• a layer of relatively rigid material having first and second surfaces;
• a film of permanently static-dissipative material applied to one of said first and second surfaces, said film having a surface resistivity of more than 10.sup.5 but less than 10.sup.12 ohms per square, said layer and said films being naturally degradable, wherein said film comprises cellophane.

A multiple-ply packaging material comprising:

• a layer of relatively rigid material having first and second surfaces;
• a film of permanently static-dissipative material applied to one of said first and second surfaces, said film having a surface resistivity of more than 10.sup.5 but less than 10.sup.12 ohms per square, said layer and said films being naturally degradable, wherein said film comprises glassine.

A multiple-ply paperboard comprising:

• a first film of amine free, permanently static-dissipative material;
• a second film of amine free, permanently static-dissipative material;
• a layer of paperboard having first and second sides, said first and second films being applied to said first and second sides, respectively, of said paperboard so as to sandwich said paperboard between said first and second films, said first and second films having a natural surface resistivity of more than 10.sup.5 but less than 10.sup.12 ohms per square, said layer of paperboard being applied between the two films while the films are in a solid state, and each of the films having the same solid, amine-free permanently static dissipative characteristics before and after said application, said first and second films and said layer being naturally degradable and recyclable.
