Material for packaging - and package or receptacle made of such material - that contains a particular aluminized polymeric film with emissivity of equal to, or less than 0.10 and yet sufficiently thin to withstand and satisfy industrial requirements of the recycling process due to substantially complete oxidization of aluminum during the recycling. An optional protective coating (less than one micron in thickness) may be added to protect aluminum in the film from corrosion during the normal use of the packaging. Protective coating is configured to not raise emissivity of the aluminized surface above the 0.10 value and, at the same time, to still allow for the aluminum material it covers to be removed due to becoming fully oxidized and corroded in the heat and at humidity levels used in the recycling/repulping process. Proposed configuration permits the aluminum of the packaging material to be included in the recycled portion of the packaging material.
