Zip-closure food storage bags you buy at a grocer lack enough resilience (stiffness) to hold food and hot (or boiled) water safely. As a result, using these types of bags for your DIY boil-in-a-bag meals can result in melted zippers, collapsed bags, spillage, and burns. Packit Gourmet Cook-in Bags solve this issue with a plastic material that’s much stiffer, and with a gusseted bottom that stands up on its own, even under the heat stress of boiled water. That means you don’t have to worry about spilling your food or tucking the bag inside your jacket on a cold night while your dinner rehydrates.

(A note on toxins: Most zip-closure food storage bags no longer contain bisphenol A (BPA). This includes both Ziploc brand (popular) and the Packit Gourmet bags mentioned here. BPA is a known endocrine disruptor, but it’s rapidly disappearing from most plastics that come into contact with food. In addition, many plastics can release dioxins. Dioxins are carcinogenic, cause reproductive and developmental problems, damage the immune system, and can interfere with hormone balance. However, heat doesn’t generally release dioxins. But chlorine does – so using any plastic container as a water treatment container when combined with chlorine (bleach) could be a risk. More research is needed here, so do your due diligence and contact the container manufacturer for more specific information.)
