Our patented high-barrier Delbar® piston eliminates permeation through the piston and bypass of propellant around the piston sidewall, ensuring separation of the product from the propellant. This maintains the purity and integrity of your product throughout its shelf life, and eliminates propellant loss. Ultramotive’s piston barrier system also provides a controlled and uniform product discharge rate, and assures complete elimination of product which is economical for both you and customers. Our barrier packaging capabilities include piston, pouch and bag methods. We can pack viscous materials including silicones, greases, personal care creams and food products so they dispense efficiently, reliably and in an environmentally responsible manner. Experience and proprietary technologies have enabled us to succeed where others have failed.
