This contribution is courtesy of my colleague on Packaging Digest, executive editor Lisa Pierce, who uncovered ValvPak, the first foray into liquids by the resealable packaging specialists at Zip-Pak (Carol Stream, IL).

The new and patented flexible valve technology provides controlled dispensing and spill-proof containment of liquids in flexible packaging. It’s a discrete flexible valve that yields when pressure is applied to the product compartment, enabling controlled dispensing. When squeeze-pressure is released, the valve reoccupies and closes the dispensing channel. The design is based on trapped air bubble within layers of film.

Zip-Pak provides spooled valves for inline application on vertical or horizontal form-fill-seal machines.

A beta launch is planned in 2019, with commercialization in the second half of the year with a global brand owner in the home care or personal care area.

Food and beverage applications are in the future, as well as valved pouches for dosage opportunities, she reports.

It’s also attracting interest in brands involved in ecommerce where, according to Zip-Pak via Pierce, “ValvPak customers centered around ecommerce are looking for less weight, no leakage and concentrated products.”
