When it comes to preserving your food, the best vacuum sealer bags are almost as important as the machine that seals them. Luckily, once you work your way through your machine's starter pack, the internet has ample replacements. Most of them are affordable and effective, but how do you narrow it down?
The first thing you'll want to consider is compatibility. The vast majority of brand-name vacuum sealers make their own replacement bags — but generic brands are usually much more affordable and can work just as well. Before you buy anybags, however, you'll want to check the measurements and compatibility of your machine. (Most full-size machines can seal bags up to 12 inches wide, but double-check anyway.)
Next, decide whether you want vacuum sealer rolls or bags. Both will serve the same purpose — they'll store your food in an airtight environment to keep it fresher for longer. That said, while you can simply put your food in a bag and seal it on one side, rolls require an extra step. They come in a tube-like shape, so you'll need to seal both sides: one before you put the food in, and one after. While rolls may require a little extra work, they're usually more affordable and easier to store in your kitchen. They're also easier to customize to the size you want. Finally, since there's heat and moisture involved, you'll want to choose a bag that's strong and free from BPA and other toxins. (This is especially important if you're using your food sealer for sous vide cooking, as you don't want the plastic to break down and transfer chemicals into your food.)
