An easy open tear control package, preferably a pouch, from a film of polymeric barrier material is disclosed. Methods and films for making of such packages are also disclosed. The easy open tear control feature arises from roughening portions of the outer or inner surface of the films, prior to fabricating into the package. The roughened portion is on one face or on each face of the package and is at least a full width of a seal when the film is made into the package. The roughened portion can extend the entire width of the package and can be of any desired length. A preferred film is a continuous extrusion laminated film comprising, a plurality of superimposed layers which comprise from outer surface to inner surface, a first layer of polyester, a second layer comprising a vinylidene chloride copolymer, preferably a vinylidene chloride methyl acrylate copolymer, a third layer of ink, a fourth layer of primer, a fifth layer of low density polyethylene, a sixth layer of ethylene vinyl acetate, and seventh and eighth layers each of an ionmer resin.
