As a green living coach I did struggle a bit with this plastic use but it has drastically reduced food waste in my home. Plastics are most likely to leach into foods when heated, and with this product I only freeze foods.
The trick to this is to put foods in the freezer for about an hour and THEN wrap them using the Foodsaver. This ensures no air gets in the bag and the food lasts a good long time.
This product, used with freezer meal cooking in advance, can save a lot of time and money on food, Used for leftovers that won't be eaten in the next day or two, it also saves on food waste, so although I debated reviewing a product that uses disposable plastic, I feel the reduction of food waste is worth it. And I have to say I use it often and it doesn't take long at all to learn how to make the bags with the least amount of plastic possible.
this also comes with a tube that removes air from re-usable containers that comes in handy for soups and for marinating.
