Every day, Aptar creates “a-ha moments” for its customers and their consumers and patients by continually bringing innovations to market that convert non-dispensing packaging into breakthrough product-dispensing systems, including those that give people more effective ways to put on their favorite fragrance, kids the opportunity to pour ketchup without making a mess and patients connected technologies that help them more easily adhere to treatment.
