PURPOSE:To adhesively attach a lidding material, comprising a metal foil and sealant, to a container with high accuracy and enable taking the lid off lightly by a packing method wherein the lidding material is given perforation preliminarily, fed by an accurate pitch to containers, heat-sealed, and then the waste part is torn off from the perforated parts. CONSTITUTION:A lidding material 1 is slit to a breadth allowing the margins 3 to be easily torn off at perforations 2 and in a required shape and to a suitable length. This lidding material 1 has lids 4 in a row and is wound in a coil to be fed to a sealer. The lidding material 1 is fed to the sealer at the same pitch as containers 6 filled with contents, positioned accurately and simultaneously has the lid 4 attached by fusion to a flange 7 by a heat-sealer. The waste lidding material 1 is torn off from the lid 4, leaving the container 6 sealed. This method enables adhesively lidding a container 6 with high accuracy and taking the lid 4 off lightly. |
