Non tox food containers for commuting

Hi there! New to the group. I switched a lot of my containers from plastic to glass, but glass is SO heavy. I commute from Jersey to the city everyday and i really want to start bringing my lunch (I’ve been buying everyday 😩) any recommendations for below- i feel like im looking for a unicorn lol

- lightweight - so preferably not glass

- microwaveable (preferred)

-non toxic

Thank you!!!
