Hot water soluble packaging materials

A method of disposing of packaging after the contents of the packaging has been removed, said packaging having an internal space defined by thermoplastic polymer side walls being capable of dissolving in water and aqueous solutions only at temperatures above approximately 37.degree. C., and subjecting said packaging to water at sufficient temperature to substantially dissolve said thermoplastic polymer side walls whereupon said water and dissolved packaging are subjected to disposal said thermoplastic polymer comprising a polyvinyl alcohol that is produced from crystallized substantially totally saponified polyvinyl acetate.

A method of disposing of packaging after the contents of the packaging has been removed, said packaging having an internal space defined by thermoplastic polymer side walls being capable of dissolving in water and aqueous solutions only at temperatures above approximately 37.degree. C., and subjecting said packaging to water at sufficient temperature to substantially dissolve said thermoplastic polymer side walls whereupon said water and dissolved packaging are subjected to disposal said thermoplastic polymer being approximately 10 to 200 grams per square yard in weight.

C., and subjecting said packaging to water at sufficient temperature to substantially dissolve said thermoplastic polymer side walls whereupon said water and dissolved packaging are subjected to disposal said thermoplastic polymer being approximately 20-100 grams per square yard in weight.

A method of disposing of packaging after the contents of the packaging has been removed, said packaging having an internal space defined by thermoplastic polymer side walls being capable of dissolving in water and aqueous solutions only at temperatures above approximately 37.degree. C., and subjecting said packaging to water at sufficient temperature to substantially dissolve said thermoplastic polymer side walls whereupon said water and dissolved packaging are subjected to disposal said thermoplastic polymer being approximately 30-70 grams per square yard in weight.

A method of disposing of packaging after the contents of the packaging has been removed, said packaging having an internal space defined by thermoplastic polymer side walls being capable of dissolving in water and aqueous solutions only at temperatures above approximately 37.degree. C., and subjecting said packaging to water at sufficient temperature to substantially dissolve said thermoplastic polymer side walls whereupon said water and dissolved packaging are subjected to disposal and wherein a portion of said thermoplastic polymer side walls are substantially transparent so as to reveal the contents of said package before opening.

A method of disposing of packaging after the contents of the packaging has been removed, said packaging having an internal space defined by thermoplastic polymer side walls being capable of dissolving in water and aqueous solutions only at temperatures above approximately 37.degree. C., and subjecting said packaging to water at sufficient temperature to substantially dissolve said thermoplastic polymer side walls whereupon said water and dissolved packaging are subjected to disposal said thermoplastic polymer side walls being substantially opaque.
