Insulating wrap

A method of forming an insulating wrap, comprising the steps of:

• providing a die having a plurality of cavities defined therein, and evacuating means associated with each cavity and operable for producing a low pressure in each cavity;
• positioning a first film over said cavities;
• said first film being a flexible thermoformable film;
• creating a low pressure in each cavity to deform said first film to define the shape of said cavity;
• filling the first film cavities with a liquid capable of being frozen;
• covering said first film with a second film;
• said second film having a layer facing said first film which is heat sealable layer and a layer facing away from said first film which is relatively thermally insulating layer;
• and
• heating sealing said first and said second films together to encapsulate said liquid by applying heat to said first film below said second film and pressure to said second film above said first film;
• whereby, said first and second film form an insulating wrap having a plurality of pouches of liquid with substantially no damage to said insulating layer.
