Our bags are durable to extreme heat and cold ranging from -76°F (-60°C) to 428°F (220°C) which makes them a kitchen must have. Safely store your family left overs / prep your meal ahead / keep your vegetables fresh in the freezer / refrigerator. Then when you need to eat, just put the bite’n’pack silicone food bag in the boiler / microwave to have a quick meal. You can also marinate your meat inside and cook sous vide using the bag.
