Plastic-free food storage doesn't have to be a headache. Here are some simple ways to get the disposable plastic out of your kitchen.

Replace plastic storage containers with mason jars, glass Pyrex, or other glass or stainless steel containers.
Chemicals present in plastic can leach into your food, especially when heated up, so don't feel bad about ditching the plastic takeout containers you have been hoarding. Mason jars are a great affordable way to store food in the fridge and freezer. I bought some glass Pyrex containers (with plastic lids) early on in my plastic-free journey that work pretty well, too. Life Without Plastic also sells some glass storage containers that don't use any plastic in them at all--they are glass with a stainless steel lid.
You don't need plastic wrap or ziploc bags.
Ziploc bags are not the only way to prevent freezer burn, despite what the advertising tells you. A well-sealed glass container does the job just fine. I usually freeze food in my Pyrex containers, but if you're using a mason jar, try using a widemouth one, and leave plenty of space at the top.
I really have not missed plastic wrap or plastic storage containers once since I've made the switch--glass containers and jars have worked very well for me. Glass or stainless is healthier for you and lasts longer (creating less waste).
If you aren't familiar with Plastic Free July, take a look at this post. Basically, it's a month-long challenge to reduce the amount of disposable plastic you use. It's a great starting point if you just want to give cutting out disposable plastic a try.
My first Plastic Free July was in 2013(!), and this month I'd like to highlight some of the things I do to reduce my plastic use, and some struggles. Many things are part of my routine at this point (buying in bulk, refusing plastic silverware, etc.), but I am not perfect, and I always find this challenge to be a good time to refocus and look at what trash I am actually producing.
