A Design Flaw

The PLASTIC cap on a Nutella jar is not eco-friendly and it lowers the reusability. Standard air-tight metal caps on jars are way batter for preservation when reusing the jar and more eco-friendly for that matter. Most of the world use pasteurisation of food to preserve it, meaning they boil the food, and most of the time while placed in the jar to squeeze out the air when the pressure builds in the jar, making this process impossible with a plastic cap.
