Description of the invention (10) Small strength line It may differ from the preferred form shown in FIG. 5 'the line of minimum strength does not extend completely across the opposite edge of the sealing element 5' and is terminated before reaching the edge. The multilayer assembly of the sealing element 5 is preferably from Raw material As shown in Figure 2, a convenient method for providing multilayer assembly of the sealing element is to provide two minimum strength lines that are substantially parallel to the overall machine direction (MD). The configuration will be borrowed A minimum strength line is provided on the first layer by, for example, a perforated member or a grooved member, which provides a groove or a perforated line substantially parallel to the machine direction. The raw material is added from the machine direction to provide as shown in Figure 2. The best assembly of the sealing element. It can provide the minimum strength line on the first layer in various forms. Referring to Figure 15_17, it can cut the first layer as a whole to define the minimum strength line (Figure 15) and provide a perforation effect (section (Figure 16) or provide a thickness reduction line (Figure), or a combination of these. In the form of the present invention having only the first layer and the second layer, the minimum intensity line still exists in the first layer, in which the first layer is the uppermost layer when sealed to the container. The package is not completely air-tight when the alternative form and its minimum strength thread are perforated or recessed. When the sealing element with the first layer and the second layer is required to provide an air-impermeable packaging, the minimum strength line will have to be a thickness reduction line so that there is no hole through the first layer before the area 10 can be lifted. In a preferred form of the invention, the third layer 6 is preferably made of an air-impermeable substance.

The container is truly air tight until the preferred layer is torn apart. The third layer is at least partially sealed to at least a portion of the first layer 7 facing up. The sealing effect of the third layer is such that it covers the area 10 which is at least partially defined by the minimum strength line 9. As shown in FIG. 10, the covering is only adjacent to the minimum intensity line 9, or alternatively and optimally, the peripheral layer of the third layer 6 has substantially the same size as the first layer 7, so that it substantially covers the first layer 7 entirely. The first (upward in use) major surface. The third layer 6 is preferably sealed to at least part of the first major surface of the first layer 7 by a suitable sealing method such as an adhesive. The sealing effect is preferably at least along the area 10, but with reference to item 9), it is preferably the first major surface of the entire first layer 7. Referring to Figure 21, it can be seen that a very small amount of sealing effect near the minimum strength line is sufficient. Although the adhesive is the preferred form of the sealing layers 6 and 7, other sealing methods may be used. The configuration of the second layer 6 and the first layer 7 is such that when the area 10 is lifted, the third layer 6 will be torn apart. By properly selecting the substance of the third layer, the properties of the substance can facilitate the tearing action with less effort. The substance may include a foil substance such as aluminum foil or a plastic substance such as Bopp (biaxial polypropylene). It can be seen from FIG. 3 that how the lifting effect of the region 10 and the tearing effect of the third layer expose at least part of the second layer 8 below the region 10 ^ The tearing effect exposes at least one gap of the second layer 8. Therefore, the preferred substantially air-tight sealing device of the opening area 2 of the front container since self-tearing produces a packaging which is at least partially exposed to the surrounding environment after tearing.
