Storage bag

Abstract

The present invention provides a storage bag including a bag body including two opposing sidewalls, the sidewalls including peripheral edges and the sidewalls being attached together along at least a portion of the peripheral edges. Each of the sidewalls include an outer surface and an inner surface, where the inner surfaces define opposing inner faces, and at least one of the inner faces includes a pressure sensitive composite material. In accordance with another aspect of the invention, a process for forming a storage bag material is provided including the steps of: providing a sheet of base film; providing a pressure sensitive composite material having an adhesive on one side thereof; moving the sheet of base film and the pressure sensitive composite material into overlaying engagement; and attaching the pressure sensitive composite material to the sheet of base film.

1 . A storage bag comprising: 
 a bag body comprising at least two opposing sidewalls, said sidewalls including peripheral edges and a common bottom edge, and said sidewalls attached together along at least a portion of said peripheral edges;    at least one said sidewall comprising an outer layer and an inner layer; and    said inner layer comprising an upper edge and an inner face,    said inner layer attached to said outer layer along the bottom edge, the peripheral edges and the upper edge,    said inner layer substantially unattached to said outer layer between said upper edge and said bottom edge, and between said peripheral edges,    said inner face comprising protrusions and valleys adjacent said protrusions with an adhesive at least partly filling said valleys,    at least one sidewall comprising a valve passage.    
   
   
       2 . The storage bag of  claim 1  wherein the valve passage comprises a one way valve.  
   
   
       3 . The storage bag of  claim 1  wherein said bag body includes an opening and a closure element comprising cooperating complementary elements located at said opening.  
   
   
       4 . The storage bag of  claim 3  wherein said valve passage is disposed below said closure element.  
   
   
       5 . The storage bag of  claim 1 , wherein the sidewall opposite the valve passage is adhesive free.  
   
   
       6 . The storage bag of  claim 5 , wherein the sidewall opposite the valve passage is textured.
