Typically, after tearing the seal, if the contents of the container are not used up at one time, the seal is deteriorated after the cap is re-applied. Resealing may also be performed by providing a resealing outer ring.
In a further preferred scheme, a plurality of adhesion points are arranged between the arched part and the re-press-sealed outer ring, between the arched part and other areas of the inner ring, and between the re-press-sealed outer ring and the inner ring.
In a preferred scheme, a plurality of protruding points are arranged on the lower surface of the handle part. Through setting up a plurality of bumps at the lower surface of handle portion for the combination of handle portion and aluminium layer is loose, breaks out the handle portion off with fingers and thumb and pulls up from the aluminium layer more easily.
In a preferred embodiment, the adhesive layer is directly laminated on the lower surface of the aluminum layer.
In a preferred embodiment, the backing layer is laminated on the upper surface of the aluminum layer by an adhesive layer.
In a preferred embodiment, the backing layer includes a PE foam board and a PE film, and the PE film is laminated on the upper surface of the PE foam board. The backing layer may also be a plastic film, cardboard, foam board or plastic board.
The utility model has the beneficial effects that: the semi-tearing sealing gasket can keep the sealing gasket flat after sealing, can open a semi-opening with a neat boundary when uncovering, and is easier to tear the aluminum layer.

Detailed Description
The utility model is further described with reference to the drawings and the specific embodiments below:
1-2, a semi-tear seal gasket comprises an adhesive layer 1, an aluminum layer 2 and a backing layer 3, wherein the adhesive layer 1 is attached to the lower surface of the aluminum layer 2, and the backing layer 3 is attached to the upper surface of the aluminum layer 2; the handle part 301, the strip-shaped tearing line 302 and the arched tearing line 303 which are formed by die cutting of the backing layer 3 are arranged on the backing layer 3, the hollowed-out part 304 is arranged on the area, which is positioned on the periphery of the handle part 301, of the backing layer 3, the arched tearing line 303 surrounds the arched part 3031 on the backing layer 3, the handle part 301 and the hollowed-out part 304 are positioned in the arched part 3031, and the root part of the handle part 301 is connected with the arched part 3031; one end of the strip-shaped tear line 302 is connected to one side of the handle portion 301, and the other end of the strip-shaped tear line 302 is connected to the arcuate tear line 303.
The semi-tear sealing gasket is generally applied to plastic containers, paper containers or aluminum containers, wherein the upper ends of the containers are provided with openings, the edges of the openings are provided with sealing edges, and the adhesive sealing layer 1 of the semi-tear sealing gasket is adhered to the sealing edges.
