Confidence in Your Choice of Glass Food Container

Pulished on May. 01, 2019

Aside from personal preference, the choice depends on environmental and safety concerns, space and weight considerations, and functionality. Below, we've laid out the factors to consider when choosing between glass and plastic, and determined a winning material for each category.


FOR THE ENVIRONMENT: GLASS

First up: recycling. With care, glass containers will last almost indefinitely, and if you do discard of them, they're 100 percent recyclable. An unfortunate amount of plastic, however, can't be recycled in most municipal recycling programs. (Plastics are labeled with numbered symbols and local programs typically recycle some, but not all, of the labels.) According to a recent study, approximately 6300 metric tons of plastic waste had been generated as of 2015, 9 percent of which had been recycled.


FOR YOUR HEALTH: GLASS

Even when you choose BPA-free plastic, toxic, endocrine-disrupting chemicals may migrate into your food during microwaving. Glass has a non-porous surface that doesn't absorb like plastic and can be safely washed at higher temperatures in your dishwasher without melting or warping—most food storage containers made of glass are designed to withstand high heat without breaking.


FOR STORING LEFTOVERS IN THE FRIDGE & FREEZER: GLASS

For storing food in the fridge or freezer, glass, particularly OXO's set wins. The containers are freezer-safe so the glass won't break, leakproof with a tight seal (no mysterious liquids sticking to your refrigerator shelves!), and easy to clean. Plus, you don't have to worry about glass releasing chemicals when frozen. Jingnuo glass bakeware dishes, also freezer-safe, are particularly useful for cooking big batches and storing half in the freezer.


FOR AESTHETICS: GLASS

From a personal standpoint, I'd much rather serve a dish from glass containers than from plastic. They're pretty close to actual dishware and don't absorb smells or stains—no frightening marinara discoloration after one too many uses. In modern classics or vintage patterns, glass, particularly Jingnuo, wins my heart and my open shelving space.
