Sustainable is a very important word to understand. If your packaging reduces how much packaging is being used (instead of rigid bottle you are using flexible pouch)…that’s a Sustainable Example and a Huge Win for the Environment. If you use a rigid bottle but sell “refills” in flexible packaging (instead of selling more product in rigid bottles)…that’s another Huge Win for the Environment. If you switch to a flexible pouch to ship your liquid instead of using a rigid container (think a pouch versus a windshield washer 2 gallon jug) not only is this a Huge Win for the Environment…your flexible packaging ships flat, stores, flat, takes up less space, uses less energy to make, requires less fuel to ship, etc. Again…Huge Win!
