EASY-OPEN AND RE-SEALED FLEXIBLE FILM PACKAGES AND METHODS OF MANUFACTURING Russian patent published in 2015 - IPC B65D75/58 B65B9/20 B65B61/18 

FIELD: packaging industry.

SUBSTANCE: invention relates to flexible film packages with re-sealed opening. According to the invention, the packages have a housing limiting the inner space for the contents, and comprise the first and the second end seals (36, 38) and the longitudinal seam (40) connecting the edges, extending from the first end seal to the second end seal. At that the housing comprises the first lateral part (40) having a longitudinal seam connecting the edges and the second lateral part (30) opposite the first lateral part, the marking (24) on the second lateral part of the flexible film, indicating the opening after the initial tearing, a closure layer (26) covering the marking and a part of the second lateral part around the marking and expanding at least to the part of the first lateral part. At that the closure layer on the second lateral part can be at least partially removed from the flexible film for tearing the marking and forming an opening, and the closure layer on the first lateral part resists the further removal of the closure layer from the flexible film.

EFFECT: improvement of the design.
