Abstract
A flexible container incorporating flexible front and rear sheets with a perimeter seal in which at least one length or section of the perimeter seal can include a seal weld that has both a permanent seal section and a pressure absorbing seal section. The pressure absorbing seal section is configured to peel, fail, or split when the flexible container, filled with a solution or liquid, is dropped onto a hard surface to thereby absorb the impact of the drop. The flexible container can be provided with one or more dispensing and/or additive ports or without any port. The flexible container may include more than one compartments with a peelable seal separating two adjoining compartments of the flexible container.
