- imgabe 4y agoThey're extremely cheap to make and very light yet strong. A plastic jar is going to weigh like 10% of what a glass jar the same size weighs and it won't shatter if you drop it. That's a pretty big advantage when you're shipping a tractor trailer full of jars of spaghetti sauce or something.
- themeiguoren 4y agoWeight is also a proxy for how much energy it took to make a product. If you only use your metal or glass straw / jar / etc that weighs 5x what a plastic one does a single time, you aren’t saving anything. Yes the metal one can be recycled, but do you think the recycle rate on those is high enough amongst the general pubic for them to come out ahead environmentally?
