I've been using this gallon bag for meal prepping and it holds a full head of lettuce plus other veggies without squishing anything. The seal is strong and it's easy to clean too.

Finally a bag that actually fits a whole head of lettuce without squishing it. The generous size makes it perfect for bulky leftovers too.

I use these for storing bulk flour and sugar, and the seal is so airtight that nothing spills even when I toss the bag in my camping cooler. They're sturdy enough to handle heavy loads without leaking.
