What are some non-plastic food storage alternatives?

my fiancee won’t allow plastic containers to be used for food. he read a study linking the leached chemicals to the higher rate of autism in kids today. i know plastics give off bad things, but they’re SO convenient! even the glass pyrex-type dishes have plastic lids. don’t those give off chemicals? i have seen all glass containers made by anchor-hocking, but how do i pack my lunch without them breaking?
