"green" temperature- controlled mailer

Abstract

A mailer has an outer, longitudinally extending, biodegradable film with lateral edges folded on itself to form a pocket having an opening and sealable by a flap. An assembly is composed of an inner, longitudinally extending, biodegradable film having lateral edges and a longitudinal extending pad composed of textile cuttings and microbial and super-absorbent powders. The inner film extends longitudinally around the pad and is attached to the pad. The assembly is positioned in the pocket with the inner film being sealed to the outer film adjacent the opening to the pocket trapping the pad between the outer and inner films. Sealing tape is mounted on the inner film adjacent to the pocket to seal the pocket closed. The lateral edges of both the outer and inner films, which extend laterally beyond the pad, are heat sealed together.

1 . A mailer comprising an outer, longitudinally extending, biodegradable film having lateral edges folded on itself to form a pocket having an opening and sealable by a flap, and an assembly composed of an inner, longitudinally extending, biodegradable film having lateral edges and a longitudinal extending pad composed of textile cuttings and microbial and super-absorbent powders, with said inner film extending longitudinally around the pad and being attached to the pad, said assemble being positioned in said pocket with said inner film being sealed to the outer film adjacent the opening to the pocket trapping the pad between the outer and inner films, a sealing tape mounted on the inner film adjacent to the pocket to seal the pocket closed, the lateral edges of both the outer and inner films extending laterally beyond the pad and being heat sealed together. 
   
   
       2 . A mailer according to  claim 1  wherein the inner film is stitched to the pad adjacent to the heat sealed lateral edges of both the outer and inner films. 
   
   
       3 . A mailer according to  claim 1  wherein the pad is unattached to the outer film. 
   
   
       4 . A mailer according to  claim 1  wherein the pad is from about 5 mm thick to about 25 mm thick. 
   
   
       5 . A mailer according to  claim 4  wherein the pad is about 15 mm thick. 
   
   
       6 . A mailer according to  claim 1  wherein the outer film is from about 2 mils thick to about 6 mils thick. 
   
   
       7 . A mailer according to  claim 6  wherein the outer film is about 4 mils thick. 
   
   
       8 . A mailer according to  claim 1  wherein the inner film is from about 0.5 mils thick to about 5 mils thick. 
   
   
       9 . A mailer according to  claim 8  wherein the inner film is about 3 mils thick.
