Embodiment Construction

[0022] Such as figure 1 , figure 2 , image 3 As shown, a peelable sealing lidding film includes a film body 1, and the film body 1 includes a barrier layer 2 and a heat-sealing layer 3. The barrier layer in this embodiment adopts an AL layer, and also includes a barrier layer arranged on the barrier layer. An easy-peelable coating 4 between the layer 2 and the heat-sealing layer 3, the easy-peelable coating 4 is prepared by a mixture of nitrocellulose and polyurethane, the heat-sealing layer 3 is prepared by casting polypropylene, and The heat-sealing layer 3 is provided with a cutting line 5 where the barrier layer 2 and the heat-sealing layer 3 are delaminated when peeled off, and the heat-sealing layer 3 is also provided with a through hole 6 .

[0023] First, the connection between the barrier layer 2 and the heat-sealing layer 3 is realized through the easy-peelable coating 4. During use, when the barrier layer 2 is uncovered, due to the effect of the cutting line 5, ...

Abstract

The invention relates to a sealing cover film capable of being peeled after uncovering. The sealing cover film comprises a film body, the film body comprises a blocking layer, a heat seal layer and aneasy-to-peel coating arranged between the blocking layer and the heat seal layer, and the heat seal layer is provided with a cutting line and a through hole. The film has the advantages that throughthe easy-to-peel coating, connection between the blocking layer and the heat seal layer is achieved, and in the using process, when the blocking layer is uncovered, under the effect of the cutting line, the blocking layer and the heat seal layer are quickly layered; since the heat seal layer is always in contact with a cup body in the uncovering process, the phenomenon that in the existing uncovering process, contents are easily spilled or leaked laterally is effectively avoided; moreover, the overall structure is simple, the processing difficulty is low, the cost is low, since the blocking layer and the heat seal layer are easy to peel, great convenience is provided for recycling, the blocking layer and the heat seal layer can both serve as the raw materials for secondary utilization andbe conveniently disposed, and therefore, the environmental protection property is good.

Description

technical field [0001] The invention relates to a peelable sealing lidding film. Background technique [0002] The existing sealing lid film generally adopts a three-layer structure, including a varnish layer, a barrier layer and a heat-sealing layer. After the existing three-layer structure sealing lid film is compounded, the sealing cup is directly sealed, and the entire lid film is sealed when it is torn apart. Uncovering, so the composite fastness strength between the cup mouth and the cover film is required to be high. The content is easy to spill, and when the heat seal strength is too low, it is easy to cause side leakage. In addition, when the peeling strength of each single-layer film is low, it will bring inconvenience to consumers. Contents of the invention [0003] The object to be achieved by the present invention is to provide a peelable sealing lidding film to solve the technical problem that the contents are easily spilled during the unraveling process cau...
