Yep. Not only do you avoid plastic but you eat better too because you have hard lines that are not to be crossed.
No more chocolate bars, ready meals, pot noodles, bags of crisps or whatever else.
Even if you end up buying a bag of rice in plastic you're cutting down the waste by a huge amount because even a small one gives you ten or more servings.
I once got a 10KG sack of rice from an Asian store once. After a year it got full of tiny bugs less than 1mm in size. Now I buy 1kg bags that I can more easily seal airtight with pegs.
