These boilable bags save me a lot of time working in a retirement home cafeteria. It saves time and money to prepare a meal days or weeks in advance, so we vacuum package various portions for storage. There are a few dishes like soups and sealed vegetables that we take directly from the freezer and throw into boiling water before lunch. We cook 20-50 pouches of sealed food every week and haven’t had any issues with poor seals or leakage.
