Reducing unnecessary air exposure helps limit drying and quality loss during frozen storage. The packaging still needs to be appropriate for the food and securely sealed.
What the observation tells you
A loosely folded supermarket bag is different from a freezer-suitable container or properly closed bag. Sharp food edges can puncture thin material, while overfilled liquid bags can leak as their contents expand. Packaging quality does not establish that the food was safe before freezing.
A useful next step
Use a suitable size, leave the recommended space for expansion and label the pack. Check the seal before placing it where leakage could affect other food or obstruct a drawer.
