摘要： PURPOSE: To delaminate film layers at a portion where a bond strength is low, and make a support harder than a first and a second films by projecting the first and the second films laterally beyond the support to seal both the films and making the bond strength between two layers of the first film close to an interface between the films lower than the bond strength between the films. CONSTITUTION: A bottom of a tray 5 is molded with, for example, an HDPE and covered with an underlying film 1. An overlaid film 6 having a twin-layer structure covers an upper portion of the tray 5 and forms a vacuum skin pack in which an article is set on the tray. Further, the overlaid film 6 is projected laterally and connected to the underlying film 1 at an upper portion of a sealed part S, where the two films are projected beyond the rim of the tray. The film 6 has a lower layer (seal layer 6b) and can be easily sealed to an upper portion 3 of the underlaying film 1. In order that the upper portion 3 of the underlaying film 1 can be reliably raptured at an adjacent part of the corner of the rim of the tray 5, the thickness of the upper portion 3 of the underlying film 1 is much thinner than that of a lower portion 2 of the underlying film (that is, a weak point 4 is formed in the vicinity of a bond between the underlying film 1 and the film 6).

摘要： PURPOSE:To easily open a container, by making smaller the adhesive force between the innermost first synthetic resin layer of the vessel body and a metallic foil or the second synthetic resin layer than the adhesive force by a heat- sealing between the first synthetic resin layer in the middle of the both scored lines and a heat-sealing material layer of a lid. CONSTITUTION:Two scored lines 15, 16 are made nearly along all periphery of respective brims 12 on the first synthetic resin layer 3a at the part near the opening periphery of the container body of the brim 12 and also at the base of curled edge 13. And yet, the adhesive force between the innermost first synthetic resin layer 3a of the container body 11 and the second synthetic resin layer 3b is made smaller than the adhesive force due to the heat-sealing between the first synthetic resin layer 3a in the middle of the both scored lines 15, 16 and the heat-sealing material layer 22 of the lid 21. In this way, the container 10 can be easily opened without any large force.
