The utility model mainly aims to provide a PET adhesive tape convenient to tear, which can effectively solve the technical problems in the background technology.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
The utility model provides a PET sticky tape convenient to tear, includes PET rete and glues the sticky layer, glue the bottom of sticky layer coating at the PET rete, one side of PET rete is equipped with first turn-up, the opposite side of PET rete is equipped with the second turn-up, one side of first turn-up is equipped with first sawtooth limit, one side of second turn-up is equipped with the second sawtooth limit.
As a further aspect of the present utility model, the adhesive layer covers bottoms of the first bead and the second bead.
As a further scheme of the utility model, the width of the first curled edge is 1/4 of the width of the PET film layer, and the width of the first curled edge is the same as that of the second curled edge.
As a further aspect of the present utility model, the first and second beads are integrally connected with the PET film layer.
As a further scheme of the utility model, the section of the adhesive layer is formed to be arranged in an inverted T shape.
As a further scheme of the utility model, the tooth tips of the first sawtooth edge and the second sawtooth edge are arranged in an arc shape.
The beneficial effects of the utility model are as follows:
By arranging the first curled edge and the second curled edge, the first curled edge and the second curled edge are folded at two sides of the PET film layer, so that the side edge strength of the whole adhesive tape is higher, and the tensile and tearing resistance are better;
The adhesive layer covers the bottoms of the first curled edge and the second curled edge, so that the height difference between the first curled edge and the PET film layer and the second curled edge is supplemented, and the adhesive degree of the adhesive tape after the adhesive tape is adhered to the article is ensured;
through setting up first sawtooth limit, second sawtooth limit cooperation first turn-up and second turn-up, the prong that first sawtooth limit and second sawtooth limit formed can make things convenient for the application of force to tear the PET rete, and then make things convenient for the tearing work of sticky tape after pasting, need not to borrow external tool, use convenience is higher;
because first turn-ups and second turn-ups are followed to first turn-ups and second turn-ups are covered by the viscose layer to the bottom of PET rete, compare the mode of directly seting up the breach at the sticky tape side in the traditional mode, can effectively avoid the sticky tape to appear the phenomenon of easily breaking after the atress, stability is higher.

Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
As shown in fig. 1-6, a PET adhesive tape convenient to tear comprises a PET film layer 1 and an adhesive layer 2, wherein the adhesive layer 2 is coated on the bottom of the PET film layer 1, one side of the PET film layer 1 is provided with a first curled edge 3, the other side of the PET film layer 1 is provided with a second curled edge 4, one side of the first curled edge 3 is provided with a first sawtooth edge 5, and one side of the second curled edge 4 is provided with a second sawtooth edge 6.
In this embodiment, the adhesive layer 2 covers the bottoms of the first curl 3 and the second curl 4;
Because the adhesive layer 2 covers the bottoms of the first curled edge 3, the second curled edge 4 and the PET film layer 1, the adhesive layer 2 can fill the thickness difference between the first curled edge 3, the second curled edge 4 and the PET film layer 1, and the bonding degree of the adhesive tape after bonding the articles is ensured.
In this embodiment, the width of the first curled edge 3 is 1/4 of the width of the PET film layer 1, and the widths of the first curled edge 3 and the second curled edge 4 are the same;
The arrangement of the first curled edge 3 and the second curled edge 4 ensures that the two sides of the whole adhesive tape have double-layer structures, thereby effectively increasing the edge strength of the adhesive tape and reducing the fracture phenomenon of the adhesive tape due to pressure and tension.
In this embodiment, the first curl 3 and the second curl 4 are integrally connected with the PET film layer 1;
Because PET rete 1 is connected with first turn-up 3 and second turn-up 4 an organic whole, so first turn-up 3 and second turn-up 4 are with folding mode setting, and intensity is high, and processing is convenient.
