FLEXIBLE BAGS HAVING ENHANCED CAPACITY AND ENHANCED STABILITY IN USE

摘要

The present invention provides a flexible bag (10) comprising at least one sheet of flexible sheet material (52) assembled to form a semi-enclosed container (10) having an opening defined by a periphery (28). The opening defines an opening plane, and the bag (10) has an upper region (31) adjacent to the opening and a lower region (32) below the upper region. The upper region (31) has a preferential elongation axis perpendicular to the opening plane which permits the upper region (31) to expand in response to an externally-applied force upon the bag (10), while the lower region (32) has a preferential elongation axis parallel to the opening plane which permits the lower region (32) to expand in response to forces exerted by contents within the bag (10) to provide an increase in volume of said bag (10). The bag (10) therefore exhibits increased stability in use and is easier to close.
