HiFlow E-Commerce features a metal-free pathway for optimal formula compatibility** and a showerproof design that reduces water ingression. The down locking system prevents product from actuating in transit and has been tested extensively using ISTA-6 protocols in Aptar’s certified laboratory. In addition to the down locking system, the actuator and fixture are specifically designed to combat the challenges of product distribution. Brands are able to eliminate excess overwrapping for larger size product formats reducing both waste and potential chargebacks due to damages.
