Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-2, a non-scratchable cover film includes a base material layer 1, the base material layer 1 is composed of a resin composition of metallocene linear low-density polyethylene resin, and the surrounding area of the base material layer 1 is uniform. A card slot 4 is opened, and a first clip 5 is installed symmetrically in the four card slots 4. The upper end of the base material layer 1 is pasted with a heat sealing layer 2, and the lower end side wall of the base material layer 1 is pasted with an adhesive layer 3. The adhesive layer 3 is composed of biaxially stretched polyethylene terephthalate or a resin composition containing biaxially stretched polyethylene terephthalate, and the heat-sealing layer 2 is opposite to the adhesive layer 3. A buckle mechanism is symmetrically arranged on one side;

The buckle mechanism includes a connection block 6 that is fixedly connected to the side walls of the heat sealing layer 2 and the adhesive layer 3. The end of the connection block 6 is fixedly connected to the second buckle 7. The connection block 6 and the second buckle 7 are made of elastic rubber. The side wall of the second buckle 7 is clamped with the side wall of the first buckle 5, the first buckle 5 and the second buckle 7 are integrally formed, and the four buckle mechanisms extend to their corresponding In the card slot 4, the side walls of the four buckle mechanisms are pressed against their corresponding first buckles 5, the upper end side wall of the heat sealing layer 2 is pasted with a hard coating 9, and the lower end side wall of the adhesive layer 3 is pasted with a peel-off. Layer 8.

Working principle: When using, first manually tear off the peeling layer 8, and stick the lower side wall of the sticking layer 3 on a specific electronic component. Due to the setting of the hard coating 9, the damage to the film body can be effectively avoided. Due to the arrangement between the internal first buckle, the connecting block and the second buckle, the situation of falling off between the base material layer 1, the heat sealing layer 2 and the adhesive layer 3 can be effectively avoided;

When installing the cover film, firstly, adhesive will be smeared on both sides of the base material layer 1, and then the connecting block 6 on the lower end side wall of the heat-sealing layer 2 will be inserted into the slot 4. Since the connecting block 6 , the second buckle 7 and the first buckle 5 are all made of elastic rubber, so they have flexibility. Through precision instruments, the process of inserting can be effectively realized, thereby making the first buckle 5 and the second buckle 7 tight. Fasten tightly, due to the action of the glue, it is fastened more tightly, and the connection operation process between the base material layer 1 and the adhesive layer 3 is the same;

After that, glue is applied to the upper end of the heat-sealing layer 2, and then the hard coat layer 9 is pasted on the heat-sealing layer 2. Since the side wall of the peeling layer 8 is coated with silicone oil, the peeling layer 8 is then attached to the sticking layer 3.
