I use the leakproof lids made by Ball and have been very happy with them: Ball Wide Mouth Storage Lid Leakproof 6 pk, Black, Airtight, Freezer Safe, Dishwasher Safe & BPA free (2) https://www.amazon.com/dp/B07S5Y1716/ref=cm_sw_r_apan_glt_i_74FACPZZS2D63S4SZMFS
I bought these but they only fit mason jars. I got sick of the rusting on the lids.
I am going to third or fourth or whatever number we are up to now with a recommendation to use canning jars. I find the quart and half-gallon wide mouth sizes to be best (though I have a bunch of the pint sized wide mouths, I use them to store 2-cup portions of soup for weekday lunches).
Ball makes a leakproof screw-top lid that I love. Super useful and works to take the aforementioned soup to lunch with no spills, leaks or drips in the bag. Actually more expensive than the jars, but very durable. Here's a link
I also use and love and recommend Cambro food storage containers for larger quantities of ingredients, like flour, sugar, open bags of potato chips, etc. I find the 4-liter size to be especially useful. One will hold a 5-pound bag of flour. They are made for the restaurant industry and are super durable with leakproof lids and handles that make them easy to move around. Our Costco had a 3-pack for $12.00 today -- and you can always pick them up at restaurant supply stores as well. They make clear plastic ones in a rectangular shape with colored lids, and translucent white plastic ones with plain lids. I use the translucent round ones because they are less expensive and more commonly available in our area, which does not have great shopping options. Here is an example of the ones I have. .
