SHEET PACKAGING MATERIAL FOR MANUFACTURE OF SEALED PACKAGE CONTAINING BULK FOOD PRODUCT AND SEALED PACKAGE OBTAINED FROM SHEET PACKAGING MATERIAL Russian patent published in 2022 - IPC B65D5/02 B65D5/06 B65D5/42 B65D5/74 

FIELD: packaging.

SUBSTANCE: invention relates to sheet packaging material (M, M’) intended for the manufacture of sealed package (1, 1’) with a bulk food product. In this case, packaging material (M, M’) has a quadrangular configuration with two border edges (22) parallel to longitudinal direction (A) and two other border edges (23, 24) parallel to transverse direction (B) orthogonal to longitudinal direction (A). Moreover, packaging material (M, M’) contains two transverse bending lines (25, 26, 26’) passing transverse to longitudinal direction (A) and separating packaging material (M, M’) into lower zone (27) containing lower pattern (28) of bending line location and made with the possibility of formation of lower part (3) of package (1, 1’), upper zone (29) containing upper pattern (30) of bending line location and made with the possibility of formation of upper part (4) of packaging (1, 1’), and intermediate zone (31) contained between transverse bending lines (25, 26, 26’) and intended for formation of main part (5) of package (1, 1’), having a set of side wall parts (6). In this case, intermediate zone (31) additionally contains a set of V-shaped bending lines (45), which have corresponding vertices (46) located on transverse bending lines (25, 26, 26’) or near transverse bending lines (25, 26, 26’), and set points of which are intended for formation of opposite ends of corresponding side edges (7) limiting side wall parts (6) of package (1, 1’). At the same time, each V-shaped bending line (45) passes near corresponding transverse bending lines (25, 26, 26’).

EFFECT: obtainment of a sealed package for a bulk food product.
