A few weeks ago saw the addition of the glass lunch boxes to our store from Lifefactory to complement those from Glasslock that were already in store. The Lifefactory glass lunch boxes are unique in their features and have been a really popular choices from day 1. We have been asked a few times whether they're suitable for kids to take to school, so we thought we'd give some in-depth information about these lunch boxes so you can make an informed choice. We're doing it in the format of a Q&A, including the main questions we've been asked.

Are the Lifefactory glass lunch boxes breakproof?

No. They are glass, and they do have a protective silicone sleeve around them to protect them from bumps, but they are glass, and if you drop them, there's every chance they'll break. For this reason, we don't recommend you send your kids to school with one unless you think they can safely carry it around without it getting broken. The same goes for the Glasslock containers.

Are the Lifefactory glass lunch boxes leakproof?

Yes. The lids have a silicone seal around the edge and it's held in to place by two silicone clips attached to the base cover. Once attached, that lid isn't going anywhere.

Are the Lifefactory glass lunch boxes oven safe?

Yes. The container and the silicone cover are. The lid is not. They are also microwave safe. They are an extremely versatile container that can be used for food prep, bakeware, leftovers storage and then take to work to reheat in either the microwave or a traditional oven.

Are the Lifefactory glass lunch boxes freezer safe?

Yes. However, with any glass, you need to take care. Do not go from freezer straight to the oven. Do not run under hot water straight out of the freezer or you will crack the glass. Don't fill any further than 3/4 as you need to allow for food to expand as it freezes. Overfilling before freezing will either result in the glass cracking or the lid warping.

Are the Lifefactory glass lunch boxes insulated?

No. You have two options for insulation. If you want cold insulation, your best option is to put them in a lunch bag with a couple of frozen ice packs. If you want hot insulation, you can get a really brief period of insulation with a hot pack and an insulated lunch bag, but it's not the best option. You're actually better off choosing a stainless steel food jar. Check the Thermos category for a selection of affordable solutions that will keep your lunch hot for hours.
