Packaging material and information recording media packaged by packaging material

一种通过包裹待包装物品并热密封其相互叠置的端部来密封地包装物品的包装材料，该包装材料由生物可降解薄膜构成，其中，热密封剂层选择地施加到生物可降解薄膜的位置或热密封部分上，热密封剂层设置在生物可降解薄膜中的在包装物品时彼此叠置的前表面和后表面、前表面和前表面、后表面和后表面上，并且图像图案层在热密封剂层之外形成在生物可降解薄膜上、在生物可降解薄膜的包括前表面和后表面的总面积的70％或更小的范围内。 The present invention relates to a packing material used for wrapping an article to be packed and sealing and packing the article to be packed by heat-sealing mutually superposed end parts. The packing material is composed of a biodegradable film. Heat sealing agent layers are selectively provided in the heat sealing positions or the heat-sealed parts of the biodegradable film. The heat sealing agent layers are provided on the front surface and the back surface, the front surface and the front surface, or the back surface and the back surface of the mutually superposed biodegradable film when the article to be packed is packed. On the biodegradable film, picture pattern layers as well as the heat sealing agent layers are formed within a range 70 % or less as large as the entire area including the front surface and the back surface of the biodegradable film.
