<p>PURPOSE: To obtain the package which is provided with excellent texture, scent, etc., by microwave heating and is adequate for production of bread, etc., by forming a upper web part laminated with a sensitive layer having specific surface resistance and a lower web part having a metallic foil layer to a bag form. CONSTITUTION: The sensitive layer 16 of a stainless steel, etc., which have surface resistivity of 50 to 1,000Ω/(inch)<2> is adhered by sputtering on a film 15 consisting of polyester, etc., and the paper web 18 is laminated by an adhesive layer 17 thereon to form the upper web 19. An adhesive high polymer (e.g.; polyethylene, etc.) is extruded on the other paper web 11 to form a layer 12. The metallic foil 13 consisting of aluminum, etc., is then adhered thereon and further, the layer 14 of a high-polymer material is adhered thereon to form the lower web 21. The upper web is adhered to ends 10a, 10b, 10c, by which the bag 10 is obtd.</p> |
