A lot of gum base is made from plastic. Below are some more sources.
polyethylene
vinyl acetate
These ingredients are hidden behind “trade secrets” so they aren’t listed on the wrapper.
The irony about asking if gum could be made from a plant source — what do you think it was made from originally? I’d much rather chew on chickle than something that’s going to deposit petroleum-based microplastics in my gut. I get enough of that from food packaging already. “Natural” gum bases still exist and if you Google around you can find lists of chewing gums that still use them.
Your first link is about micro plastics, and they even say not all brands have them. So if a product is made of plastic and doesn’t always contain micro plastics (which are found in the air and water and soil and foods), then…polymers might not actually be plastics sometimes. Or in gum, many times.
