In the laminating process), it is preferable to prevent the opening tab 11 from being thermally bonded to the upper surface of the lower layer 30 by the thermal adhesive resin layer 20.
- the unsealed portion 400 is treated on the lower surface of the unsealed tab (the uneven portion may be formed in a sawtooth wave shape, but may be any shape).
- the unsealed tab When the unsealed tab is laminated with the heat adhesive resin layer 20, the unsealed tab has a small contact area It is configured to be easily separated from the lower layer.
- the opening tab 11 is easily detached from the lower layer 30 by reducing the contact area when the bottom surface of the opening tab is embossed in the shape of the uneven portion 400 to be laminated with the thermal adhesive resin layer 20.
- the tab 11 is prevented from being thermally bonded to the upper surface of the lower layer 30 by the heat adhesive resin layer 20 so that the open tab 11 is separated from the heat adhesive resin layer 20 well.
- the upper layer 10 and the lower layer 30 are integrated as a result of the bonding method of the extrusion laminate, but the upper layer 10 and the lower layer 30 are integrated, but the opening tab 11 formed on the upper layer 10 is formed. Even the lower surface is thermally bonded to the aluminum foil layer or the film layer, which is the upper surface of the lower layer 30, by the thermal adhesive resin layer 20.
- the lower surface of the opening tab is attached to the aluminum foil layer or the film layer is difficult to separate the opening tab is difficult to open.
- FIGS. 7A, 7B, and 7C only the lower surface of the opening tab 11 is embossed with a lattice pattern to form an uneven portion 400 on the surface to form a heat-adhesive resin layer 20. When it is laminated with a small contact area to prevent adhesion to the thermal adhesive resin layer.
- the opening tab is a heat-adhesive resin layer in the process of laminating the upper layer 10 and the lower layer 30 by treating the silicon portion 500 only on the lower surface of the opening tab. The thermal protection of the lower layer 30 with the upper surface of the lower layer 30 is prevented.
- the opening tab 11 is not attached to the lower layer 30 and can be easily removed from the upper surface of the sealing body with a finger. After that, the opening tab 11 is held and conveniently opened.
- the present invention can be used industrially.
- the consumer grasps the opening tab and removes the encapsulation material from the container to open the encapsulation material.
- this peeling type seal is broken and cut and peeled off at the same time, so that once opened, the seal cannot be reused, giving the temper avid function to protect against malicious behavior from the outside. will be.
