Abstract
A multiple layered bag comprising such materials that one surface of the bag degrades when it comes in contact with water, for example polyvinyl alcohol, while the other surface is water resistant, such that the bag can be used to collect moist materials, for example pet excrement, without exposing the bag handler to those moist materials, yet when the everted bag is subjected to an aqueous environment, with the liquid degradable surface exposed to the aqueous environment, all the components of the bag degrade. The bag degrades such that the remaining components of the bag and the contents thereof are easily flushed down the toilet.
Claims17
A multiple layered bag comprising of a water-soluble plastic material layer and a laminated or pressure adhered biodegradable paper layer affixed to at least a portion of the surface of said water-soluble plastic material, wherein the formula of said water-soluble plastic material has been modified so that the onset of disintegration following exposure to an aqueous environment is delayed for a period in the range of thirty seconds to two hours, wherein a water retardant additive is incorporated into said biodegradable paper layer during manufacture of the biodegradable paper.
A multiple layered bag comprising of a water-soluble plastic material layer and a laminated or pressure adhered biodegradable paper layer affixed to at least a portion of the surface of said water-soluble plastic material, wherein the formula of said water-soluble plastic material has been modified so that the onset of disintegration following exposure to an aqueous environment is delayed for a period in the range of thirty seconds to two hours, whereby said multiple layered bag is manufactured by spraying said water-soluble plastic material onto a sheet of said biodegradable paper and two said sheets of said biodegradable paper sprayed with said water-soluble plastic material are joined along three perimeter edges of said sheets of said biodegradable paper sprayed with said water-soluble plastic material, such that said joined sheets of said biodegradable paper sprayed with said water-soluble plastic material form a multiple layered bag wherein said biodegradable paper layer is the exterior layer and said water-soluble plastic layer is the interior layer.
A multiple layered bag comprising:
- a water-soluble plastic material layer, a water retardant layer affixed to at least a portion of the surface of said water-soluble plastic material, and a laminated or pressure adhered biodegradable paper layer affixed to at least a portion of the surface of said water retardant layer, said water-retardant layer being in a form that disintegrates when said water-soluble layer dissolves.
A multiple layered bag comprising:
- a water-soluble plastic material layer, a water retardant layer affixed to at least a portion of the surface of said water-soluble plastic material, and a laminated or pressure adhered biodegradable paper layer affixed to at least a portion of the surface of said water retardant layer, whereby said multiple layered bag is manufactured by spraying said water retardant layer onto a sheet of said biodegradable paper, said water-soluble plastic material is sprayed onto said water retardant layer, and two said sheets of said biodegradable paper sprayed with said water retardant layer and said water-soluble plastic are joined along three perimeter edges of said sheets of said biodegradable paper sprayed with said water retardant layer and said water-soluble plastic, such that said joined sheets of said biodegradable paper sprayed with said water retardant layer and said water-soluble plastic form a multiple layered bag wherein said biodegradable paper layer is the exterior layer, said water retardant layer is the intermediary layer, and said water-soluble plastic layer is the interior layer.
A multiple layered bag comprising of a water-soluble plastic material layer, a water retardant layer affixed to at least a portion of the surface of said water-soluble plastic material, and a laminated or pressure adhered biodegradable paper layer affixed to at least a portion of the surface of said water retardant layer;
- said water-soluble plastic material layer being formed of polyvinyl alcohol;
- the formula of said polyvinyl alcohol having been modified so that the onset of disintegration following exposure to an aqueous environment is delayed for a period ranging from thirty seconds to two hours;
- said water retardant layer being formed of silicone;
- and said water retardant layer being affixed to said water-soluble plastic material by spraying said water retardant layer onto said water-soluble plastic material.
