I use these which I think are more expensive than the other persons but I highly recommend them! here!
I used to buy these https://www.amazon.com/dp/B011SY4P9I/ref=cm_sw_r_cp_apa_95EazbKHAVFS2
But this kind of container leaks pretty easily and after awhile knife cuts would sever it open.
Check out snapware.

$10 for 20 of them on Amazon right now!
