I get boxes of them with three sizes at the dollar store...wash them out and hang on something to dry...

Edit: I do sometimes wash and reuse regular cheapo zip lock storage baggies, particularly the larger freezer bags as they are more expensive....I do some small electrical and guitar/instrument/amplifier projects and find zip lock bags great for storing small parts and screws/bolts, sharpie pens work well for labeling contents....

I don't know if there's a "gotcha" hiding somewhere in the calculation of what's best for the environment either. But in addition to using fewer zip top bags we also use less saran wrap now.

They don't work for every application, and we only bought so many of them so we still use zip locks for stuff going into the freezer -- because it may be there a long while. But for stuff going into the fridge these are our go-to bags now. The ones we got seal very well which is nice for storing stronger scented things like an unused half of an onion or whatever. Washing is not so bad, drying was a hassle until we started using a little drying rack that we had for a different purpose, it holds them open well enough to get well dried.

ziploc bags, both 1gal and 1qt sizes at Costco about six years ago. I reuse them unless they contained meat which are the bags that have already been used a time or two. I finally have about four of each left. After six years, I think those bags go a long way.

The ones that contained meat are tossed after one use but the others I had wash and dry in the dishrack.

I received some as a gift and we liked how they keep everything crazy fresh. So I invested in more of the kind that stand up. I was going to ask if anyone can recommend another kind that lay flat like bags.

So far the zip tops clean well either by hand or in the dishwasher. No onion smell!!

That's the higher grade. Hopefully they last forever. If they break down too quickly then it will be a bust.

Zip top is 100% platinum silicone too.
