GENERAL PURPOSE BAG HAVING FILM AND MESH PORTIONS

摘要

A bag is made with a combination of mesh and film on both the front and back sides. For use with automatic filling machines, one side of the bag has a wicket strip with wicket holes to receive the wickets from the filling machines. If pneumatic or vacuum systems are used for bag opening, a fluid impervious assisting strip is bonded to the mesh wall at the bag mouth. A method of making such a bag includes the use of a continuous film web with adjacent continuous mesh webs. A linear seal joins the film web with the mesh webs after which the web is folded so that the free edges overlie each other. A transverse seal followed by a transverse cut results in a finished bag.
