<p>PURPOSE:To make it easier to detect metallic foreign matter mixed in food or medicine, etc., prevent the change of properties from happening, and make re-packaging unnecessary by a method wherein for metallic foreign matter detectable packaged articles for which food or medicine is packaged by a metallized film having a plastic film and an insulating metal deposited layer, metallic foreign matter is detected by a metal detector. CONSTITUTION:On the printed surface or unprinted surface of a polyethylene terephathalate film, on which an appropriate printing is performed or not performed, an insulating Sn deposited layer is formed. On the insulating Sn deposited layer, a film made of polyethylene, polypropylene, EVA, heat-sealable polyester, etc., is formed by dry lamination or extrusion lamination, etc., to constitute a metallized film. In order to obtain a metallic foreign matter detectable packaged object by packaging food or medicine, etc., by the metallized film, food or medicine, etc., may be packaged with the metallized film by heat- sealing or using an adhesive, etc., Then, by using a metal detector, metal detection is performed for the metallic foreign matter detectable packaged objects.</p> |
