    ValvPak® at PACK EXPO International 2026

    October 18 to 21, 2026 · McCormick Place, Chicago ValvPak does not have a booth this year. We have something better for a first look: our valve is in the hands of partners across the show floor, so you can hold a working sample in the context of a real line, a real film, and a real fill. If someone handed you a card, they are on the floor and available to meet. Details on where to find samples are below and will be updated as the week gets closer.

    One-Handed Control: Designing Liquid Packaging Around How People Actually Use It

    Packaging gets tested on a bench, with both hands free, full attention, and good light. Almost nobody uses it that way. They use it holding a child, driving, carrying groceries, standing in a shower, wearing gloves, or midway through cooking something else. The package is never the task. It is the interruption in the task, and the ones people keep buying are the ones that interrupt least. This post covers how common one-handed use actually is, why it is a mainstream design condition rather than an accessibility edge case, what it is worth commercially, and what a package has to do to earn one-handed control.
