Packaging bag

Abstract

This invention relates to a packaging bag. The packaging bag is made of an envelope of at least one enclosing element made of polymer material and the envelope includes a plurality of perforation holes at least on a part of the enclosing element. The packaging bag is especially suited for accommodating goods which have damageable surfaces and require air ventilation. Such goods may be agricultural products.

         14 . A packaging bag comprising an envelope having a length, width and a plurality of perforation holes, said envelope comprising:
 at least one enclosing element made of a polymer film having at least one layer, said at least one enclosing element comprising:
 at least one width joint; 
 at least two perforation-areas having said plurality of perforation holes, each of the perforation-areas forming a first straight band; and 
 at least two non-perforation-areas without perforation holes, each of the non-perforation-areas forming a second straight band; 
 at least one length joint located on one of said at least one non-perforation-areas; 
   said at least two perforation-areas and said at least two non-perforation-areas being joined at said at least one length joint to form a hose base element, said hose base element having at least one opening and an inner chamber;   wherein each perforation-area is adjacent to two non-perforation-areas and each non-perforation-area is adjacent to two perforation-areas;   said envelope having a closed position wherein one of said at least one opening of said hose base element is closed by said at least one width joint forming at least four layers at a first and second section of said at least one enclosing element, said four layers comprising two inner layers and two outer layers; and   wherein said two inner layers of said at least one width joint comprise at least a portion of a first perforation-area of said first section and at least a portion of a second perforation-area of said second section.   
     
     
         15 . The packaging bag according to  claim 14  wherein said at least one enclosing element is one enclosing element. 
     
     
         16 . The packaging bag according to  claim 14  wherein said at least one enclosing element comprises a substantially rectangular film as said hose base element. 
     
     
         17 . The packaging bag according to  claim 14  wherein each of said plurality of perforation holes have a circular, oval, rectangular with rounded corners or drop-shaped form. 
     
     
         18 . The packaging bag according to  claim 14  wherein said at least one enclosing element is opaque, partially transparent or transparent. 
     
     
         19 . The packaging bag according to  claim 14  wherein said at least one enclosing element of said polymer film is selected from the group consisting of at least one layer of polyethylene, low density polyethylene, high density polyethylene, linear low density polyethylene, ethylene vinyl acetate, polyvinylchloride, polyamide or co-polymers of said polymers and combinations of said polymers or co-polymers. 
     
     
         20 . The packaging bag according to  claim 14  wherein said at least one layer of polymer film comprises polymer film materials selected from the group consisting of plasticizer, polycarbonate, iridic and colors. 
     
     
         21 . The packaging bag according to  claim 14  wherein said plurality of perforations holes form stripes in said polymer film. 
     
     
         22 . The packaging bag according to  claim 14  wherein said plurality of perforation holes form a geometrical pattern, logos, images, letters or words on said at least one enclosing element. 
     
     
         23 . The packaging bag according to  claim 14  wherein said layer of said polymer film is printable or inscribable. 
     
     
         24 . The packaging bag according to  claim 14  wherein an area of said at least one enclosing element comprises a printing. 
     
     
         25 . The packaging bag according to  claim 14  wherein said at least two perforation-areas reach over the entire length of the envelope and said at least two non-perforation-areas reach over the entire length of the envelope. 
     
     
         26 . The packaging bag according to  claim 14  further comprising at least one handle or at least one hanger, wherein said at least one handle or said at least one hanger comprises an opening in said at least one enclosing element.
