The Reusable Express Packaging Box is designed for use in food delivery services. Fitted with a valve, an airbag, and a PVC plastic shell, it enables multiple food portions to be kept well protected for delivery. The products are placed in the box, the airbag is inflated with a portable pump, and the valve is then closed. This means that no additional packing material is needed, and individual containers can be removed quickly by releasing the air.
