Vacuum fresh packaging bag

Abstract

A vacuum fresh packaging bag is provided, which is formed by fixedly splicing edges of an upper film and a lower film and has at least one end opening formed into the bag opening. The inner surfaces of the upper film and lower film both are densely provided with many convex strips which do not intersect with each other; the convex strips form many airflow channels there-between; the convex strips on the inner surfaces of the upper film and lower film are severed once by grooves which intersect with the convex strips along the strip direction. The utility model can compress, package and store foods and valuable ornaments in vacuum.

What is claimed is: 
     
         1 . A vacuum fresh packaging bag, formed by fixedly placing edges of an upper film and a lower film, and having at least one end opening formed into the bag opening, characterized in that, the inner surfaces of both the upper film and the lower film are densely provided with many convex strips which do no intersect with each together; said convex strips form many airflow channels there-between; the convex strips on the inner surfaces of said upper film and said lower film are at least severed once by grooves which intersect with said convex strips. 
     
     
         2 . The vacuum fresh packaging bag according to  claim 1 , characterized in that the convex strips on the inner surface of said upper film and the convex strips on the inner surface of said lower film are curved or straight lines which intersect at a certain angle. 
     
     
         3 . The vacuum fresh packaging bag according to  claim 1 , characterized in that, said convex strips are wave-shaped strips extending along the edge direction of the bag opening. 
     
     
         4 . The vacuum fresh packaging bag according to  claim 1 , characterized in that, the grooves intersecting with said convex strips form different patterns or words. 
     
     
         5 . The vacuum fresh packaging bag according to  claim 1 , characterized in that the outer surfaces of said upper film and said lower film are smooth surfaces.
