Packaging design requires five technical tests for oval containers

The design and approval of oval packaging require passing five critical technical tests to ensure compatibility with printing, gluing, automatic handling, storage, and transport.

A successful design must be validated through a series of stages, starting with a white sample to test the physical properties of the cardboard, including its creases, cuts, and tabs. This stage verifies if the shape maintains its stability, volume, and structural integrity when left unsupported or after repeated openings.

Technical experts, including designers and paper engineers, must evaluate the cardboard's elastic return and the geometry's ability to distribute tension. Approving graphic designs before these structural tests is considered a mistake, as changes to the die-cut required for physical stability can shift text, windows, and decorated areas on the printed sheet.
