Of course this will happen. I try and wash my reuseable in the washing machine regularly. Wears them out faster but is a necesity.
Ones my wife picked up (against my protests of course) got 3 washes before they started falling apart. Stitching coming off so holes in some, disconnected hand straps on others.
They weren’t the cheap $1 ones either, these were the “designer” $3 to $5 a pop ones that are showing up at various department stores now.
I have meat and frozen items put in plastic bag before going into my cloth bags. Haven’t had any leakage yet...
Reusable grocery bags, ESPECIALLY when washed regularly, are significanlty harder on the environment than the disposable plastic grocery bags. Enviro-commies won't ever tell you the truth, though.
