Er, no. Those silky ones were likely worse, but a lot of the regular looking paper ones have polymer glues releasing microplastic as well.
They've since reformulated the bags - can't find any statement about the new flat bags.
Edit: Also some tea bags for loose leaf tea like t-sac or finum brands have that crimp on the edge. However, t-sac confirms they use glue, but finum specifically claims to not use glues, so maybe it is jumping to conclusions that all bags of these sort do.
