       9 . The package of  claim 8 , wherein said wall segment of each of said at least two second closure-line segments is perpendicular to said second closure-line. 
   
   
       10 . The package of  claim 1 , wherein said at least one end comprising a baffled venting closure system is selected from the group consisting of an upper end; a lower end; a side end; a spine; and combinations thereof. 
   
   
       11 . The package of  claim 1 , wherein said baffled venting closure system comprises a heat seal, an adhesive seal, or combinations thereof. 
   
   
       12 . The package of  claim 1 , wherein said package is made of a flexible sheet comprising: a thermoplastic film, a foil or aluminum substrate, a paper or cellulose substrate, and mixtures thereof. 
   
   
       13 . The package of  claim 1 , wherein said package comprises a tubular body. 
   
   
       14 . The package of  claim 13 , wherein said tubular body comprises an upper end and a lower end, wherein at least one of said upper end and said lower ends are sealed with a baffled venting closure system. 
   
   
       15 . The package of  claim 1 , wherein said package forms pillow bag, a gusseted bag, or a combination of both. 
   
   
       16 . The package of  claim 1 , further comprising a composition comprising at least one granular particle contained within said package, said at least one granular particle comprising a particle size from about 50 microns to about 5000 microns. 
   
   
       17 . The package of  claim 16 , wherein the composition comprises a laundry detergent composition; a hard surface powder cleaning composition; a powdered soap or bleach; foodstuffs comprising: any one of coffee beans or powder; a powdered or granular drink components, rice, cereal, grains, oatmeal, flour; cement; and ice melt salts. 
   
   
       18 . The package of  claim 1 , wherein said first closure-line comprises at least one wall segment, wherein said at least one wall segment parapets said first closure-line from said first closure-line vent in an orientation towards said second closure-line. 
   
   
       19 . A package comprising an inner volume and a baffled venting closure system, said baffled venting closure system comprising: a first closure-line; a second closure-line; and an air flow passage bordered by said first closure-line and said second closure-line,
