Top 10 Best Eco-Friendly Food Storage Containers in 2020 (Weck, Bklyn, and More)

This extra-large, 100% stainless steel box is made to hold a ton of food. It has three layers, with each one holding a different amount. The bottommost box can hold 22.96 ounces, the middle one 20 ounces, and the top one 7 ounces. It's also dishwasher safe and BPA-, PVC-, and phthalate-free.

Since the whole box is made without rubber or plastic, it's not leak-proof, so you can't store soups or liquids inside the container. Some reviewers also noted issues with the clasps holding the boxes together. They're quite flimsy.

On the other hand, reviewers love how sturdy the box is and how much room it has. But overall, they just love how they're reducing their plastic use effectively with this lunch box!

A couple of reviewers mention that their containers arrived cracked, as the jars are made of glass. However, most reviewers like how easy the containers are to clean, due to the wide openings, and many use them for making sourdough starters. They're also very durable!

On the other hand, most reviewers love how roomy the containers are and how the lids fit well and seal perfectly.

Other reviewers say that the box is dependably leak-proof, easy to clean, and works great for a child's lunch box.

They also come packaged in styrofoam, so beware that the shipping process itself is not super eco-friendly. Reviewers say customer service is fast to respond to any issues, however, and the jars work great for pasta and look good on any countertop.

Some reviewers do mention that the jar seems a lot smaller than it looks. However, most reviewers are in love with the design, and many use it to store coffee. The lid was a particular hit, as it did well to seal whatever is held inside the container.

Reviewers say it's great for potlucks, and when transferring warm foods, like freshly baked bread, to the table. 

This set of four glass containers are stylish and free from harmful chemicals. They're also freezer, microwave, oven, and dishwasher safe, without the bamboo lid. Each container can hold 36 ounces, and the lids can even be used as a cutting board! 

These are leak-free and airtight, as the lids so contain silicone to seal the food contents in. You can also stack them on top of each other easily to save space. 

Reviewers do warn, however, that the lids may mold, so you'll need to be careful when washing and taking care of them. On the other hand, reviewers love the aesthetics of the containers and how durable the they are.
