Is anyone concerned with microplastics using milk storage bags?

Really curious about this. We invested in all glass bottles for feeding but it feels kind of useless knowing we are using these little plastic baggies to store all the milk.

I did some research and found that lansinoh are BPA free AND phthalate free so I’ve been using those. I have motif and Medela bags free from insurance but they haven’t advertised being phthalate free.

Anyone know anything about this?
