Description

Blank for manufacturing liquid packaging container and packaging container thereof

Technical Field

The utility model relates to a blank for manufacturing a liquid packaging container and the packaging container thereof, in particular to the technical field of packaging.

Background

Containers for liquids such as fruit juice, milk and yogurt are usually provided in disposable flexible packages, such as packages formed by pressing/gluing a multilayer material including paper layers, with predetermined folds.
