Dr. Austin Lowder discusses rigid packaging and HPP
Dr. Austin Lowder talks about rigid packaging and HPP.
Key characteristics of rigid packaging that will work with HPP are generally round in cross-section, sometimes with subtle flat panels creating pseudo corners; typically premade by container supplier and provided in nested stacks to filling operation. Peel seal lid films on top flange of containers and post process applied snap fit lids. Wide openings for easy product access. Sufficiently rigid for ease of gripping by consumer, while ensuring sufficient flexibility and resiliency to accommodate distortion from the headspace compression experienced during the HPP cycle and return to original configuration after pressure release.
