Plastic film can be used as an airtight, inner
wrapping for food which is then placed into a
polythene bag, or can be used to interleave small
items such as chops, steaks, burgers ere., so that
they can be removed individually. Use freezer
quality film or double wrap food with standard
kitchen film.
Make sure that joints of meat, poultry are well
wrapped. This is to ensure that no bones can
pierce the packaging during freezer storage.
Boiling bags can be used to both pack food in for
freezing and for reheating the same food in a pan
of boiling water. They are especially useful for
items such as new potatoes, sauces and single
portions of cooked food. As much air as possible
must be extracted from the bag and an effective
seal is essential.
