Detailed Description

Referring to fig. 1 to 3, in an embodiment of the present invention, a packaging film with a cutting mechanism includes a packaging film 1 and a coating film 2, the packaging film 1 includes a film 11, a plurality of cutting segments 12 are disposed on the film 11, a plurality of arc holes 13 are disposed on the cutting segments 12, a cutting hole 14 is disposed between two adjacent arc holes 13, a viscose wool surface 15 is disposed at the bottom of the film 11, a viscose coating layer 16 is coated on the viscose wool surface 15, the coating film 2 includes a hard film 21, a coating wool surface 22 is disposed on the inner side of the hard film 21, and a water-based adhesive 23 is coated on the coating wool surface 22.

The water-based adhesive 23 permeates into the arc-shaped holes 13 and the shear holes 14 and is connected with the adhesive coating 16, and the design is used for filling the inner side spaces of the arc-shaped holes 13 and the shear holes 14, so that the negative influence of the arc-shaped holes 13 and the shear holes 14 on the overall tensile property of the film in use is reduced.

Wherein, decide segment 12 and be PVC packaging film, and decide segment 12 and cut arc hole 13 and cut hole 14 through the punching press mode, the notch department that this mode can guarantee arc hole 13 and cut hole 14 levels, reduces and leads to cutting edge tearing because of the cut-out unevenness when demolising the packing, increases the probability of demolising the degree of difficulty.

Wherein, the avris intersection department in arc hole 13 and cut hole 14 is the fillet, and this design is used for reducing after deciding, and the film is cut edge and is gone up the acute angle in arc hole 13 and cut hole 14, reduces and leads to the tearing probability of cutting edge because of the acute angle when the packing is demolishd.

The viscose coating 16 is made of low-viscosity adhesive by brushing, the water-based adhesive 23 is acrylic adhesive, the viscose coating 16 is designed to reduce the viscosity of the film 11 and the cutting sections 12 to a packing object, the package is convenient to detach and position adjustment during wrapping, and the water-based adhesive 23 is designed to fill the arc-shaped holes 13 and the shearing holes 14 and increase the bonding strength between the film 11 and the hard film 21.

The width of the cutting segment 12 is one fifth of the width of the hard film 21, the design is used for reducing the negative influence of the overall tensile strength of the film 11, which is reduced due to the design of the arc-shaped holes 13 and the cutting holes 14, on the connection strength between the hard film 21 and the film 11, and the tensile strength of the films 11 on the two sides of the cutting segment 12 is guaranteed to be qualified.

The working principle of the utility model is as follows: when the cutting device is used, the cutting device is directly pulled off from a winding roll and then covered on the surface of a product, when cutting is needed, a hard film 21 is torn off, then a film 11 is torn off along a cutting section 12, cutting sections 12 and arc-shaped holes 13 and cutting holes 14 on the cutting sections are designed to add cutting sidelines to the film 11, due to the fact that the design of the arc-shaped holes 13 and the cutting holes 14 causes the tensile strength and the lateral pulling force resistance of the cutting sections 12 to be reduced, a user can easily tear the cutting sections 12 without the assistance of external tools, wherein the cutting sections 12 can guarantee the smoothness of the cut parts of the arc-shaped holes 13 and the cutting holes 14 in a mode that the arc-shaped holes 13 and the cutting holes 14 are cut in a punching mode, the probability of tearing of cut edges caused by uneven cut edges and increasing the difficulty of removal during package removal is reduced, and the design that the intersection parts of the side edges of the arc-shaped holes 13 and the cutting holes 14 are round corners is used for reducing the cutting, the acute angle between the arc-shaped hole 13 and the shearing hole 14 on the film trimming reduces the probability of tearing the trimming edge due to the acute angle when the package is dismounted.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the scope of the present invention, and the technical solutions and the utility model concepts of the present invention are equivalent to or changed within the scope of the present invention.
