The Best Glass (Plastic-Free) Food Storage Containers of 2026

Lid material

Check what the lid is made of, including the gasket and frame. Glass, silicone, steel and bamboo keep plastic away from food. Many sets sold as glass have plastic lids or plastic latches.

Seal type

Attached silicone gaskets, as on the Bentgo, hold up best in testing. Clamp-and-ring jars like Weck seal well when the rubber is in good shape, but they are fiddly. Bamboo lids with silicone rings are not for liquids.

Heat limits

Borosilicate glass tolerates thermal shock better than soda-lime. Rated oven limits often apply to the bowl only. Lids with silicone frames usually should not go in the oven.

Weight and suction

Glass is heavy. Lids can also suction down as hot food cools, so open the steam valve before reheating or opening.

Odor and stain

Silicone gaskets can hold odors from fish or garlic. Wash them separately and air-dry fully.

Plastic-free status for every pick here comes from the maker's description of the materials, not from third-party lab testing. Bentgo describes its set as plastic-, PFAS- and BPA-free. Anyday calls its set plastic- and coating-free. PlanetBox lists LFGB-certified silicone, a European food-contact standard, though it makes no PFAS claim.

Borosilicate glass is used in the Bentgo, PlanetGoods, Anyday and Urban Green bowls. Weck does not state its glass type. If you want the least plastic in contact with food, Anyday and PlanetGoods have the simplest material lists. Bamboo lids add no plastic but must be kept dry, since damp bamboo can grow mold.

Pyrex Ultimate was out of stock on Amazon and backordered at pyrexhome.com. It has glass lids, but replacement lids are hard to find and its US glass handles thermal shock less well than borosilicate. Check it if it returns.

Rubbermaid Brilliance is America's Test Kitchen's top glass-base set, but its latching lids are plastic. The OXO Good Grips Smart Seal and Pyrex Simply Store also have plastic lids. Caraway is not fully plastic-free and was out of stock on Amazon at a very high price.

The Vtopmart bamboo-lid set covers the same need as Urban Green, with less evidence behind it.

Are glass containers with silicone gaskets plastic-free?

Silicone is not plastic, but it is a synthetic polymer. If you want to avoid it entirely, Weck's rubber-ring jars are closest, though they use a rubber ring.

Can I put the lids in the oven?

Not the Bentgo lids. The packaging warns against it. Anyday rates its lids to 400°F, and the Urban Green bowls to 600°F without lids.

Will glass containers leak in a lunch bag?

The Bentgo passed two independent tests. The Anyday and Weck were not independently tested for leaks, and the bamboo-lid set is not meant for liquids.

Why does my lid stick after reheating?

Hot food cools and creates suction. Open the steam valve or vent knob before trying to remove the lid.

Is glass safe in the freezer?

Leave room for food to expand and avoid sudden temperature swings. Weck recommends freezing only with its plastic keep-fresh covers.

For most people, the Bentgo Signature set is the safest buy: two independent leak tests, glass lids and a sensible per-container cost. Choose PlanetGoods if stiff lids bother you, Anyday if the microwave is your main tool, Weck for cheap fridge jars, and the Urban Green bamboo set only for dry goods. Whichever you pick, check the current price first, since sets like these vary between sellers.
