Non toxic storage to extend veggie life

Hi! What’s the best non toxic storage containers for veggies? I would like to cut up all of my veggies for salads, for like a week. But I am wondering if there are any really good containers people have found to keep or extend shelf life? I end up throwing 1/4 Of the veggies away at the moment 😡😢
I’m mainly storing peppers cucumbers broccolis
Cauliflower brussel sprouts leeks onions asparagus zucchini squashes ect…
Price is not a problem it it really works or extends the life!!
Thank you !!
