AI Technical Summary
In the packaging of existing food, medicine and cosmetics products, the pulling wire is prone to falling off, erroneously, off-the-top or pulling wires, affecting the visual effect and increasing the packaging cost and labor intensity of workers.
A packaging film with printed wires and balanced stress lines is used to print polyurethane ink wire lines and ordinary ink balanced stress lines on the packaging film to form symmetrically arranged wires and stress lines to reduce the physical stress of wires.
The packaging film is directly packaged without additional wires, which solves the quality defects of wires, reduces production costs and labor intensity, and improves production efficiency.

Abstract
Description
Technical field:
[0002] The invention relates to a method for manufacturing a packaging film with a printed draw line and a packaging box. Background technology:
[0004] When existing food, medicine, cosmetics, cigarettes and other products are processed, a layer of transparent packaging film is added to the outside of the paper packaging to maintain the physical and chemical properties and usability of the product and extend the storage time of the product. It is usually supplemented with a draw string to facilitate opening the package.
[0005] The use of pull wires will increase the packaging cost of the product on the one hand, and on the other hand, it will cause quality problems such as pull wire falling off, misalignment, deviation, and reverse pull wire that affect the visual effect. At the same time, replacing the pull wire during packaging will also increase the labor intensity of workers. Summary of the invention:
[0007] The present invention aims to solve the problems existing in the prior art and provides a method for manufacturing a packaging film with a printed draw line and a packaging box.
[0008] The technical solutions adopted in the present invention are:
[0009] A method for producing a packaging film with a printed draw line, producing a packaging film that meets the process standards of cigarette products, printing two ink lines parallel to the edge of the packaging film on the packaging film, and forming draw line lines and balanced stress lines correspondingly after the two ink lines are dried and formed.
[0010] Furthermore, the wire drawing lines are formed by printing with polyurethane ink and then drying.
[0011] Furthermore, the balanced stress lines are formed by printing with common ink and then drying.
[0012] Furthermore, the packaging film is a biaxially stretched POPP packaging film.
[0013] Furthermore, the two ink lines have the same width, are symmetrically arranged on the packaging film, and the distance between the two ink lines and the edge of the packaging film on the corresponding side is 1 / 3 of the width of the packaging film.
[0014] Furthermore, the two ink lines have the same thickness, which is 20-50 μm.
[0015] Furthermore, the pull line is provided with personalized information.
[0016] Furthermore, the personalized information is printed in reverse.
[0017] The present invention also discloses a packaging box, characterized in that the packaging box is packaged with the packaging film having draw lines and balanced stress lines as claimed in claim 1.
[0018] The present invention has the following beneficial effects:
[0019] When the product is packaged with packaging film, there is no need to add a draw line, and the packaging film can be directly packaged, which can solve the many quality defects of using draw lines, reduce production costs, improve production efficiency, and provide effective help in reducing product packaging costs. Description of the drawings:
[0021] Figure 1 This is a schematic diagram of a packaging box after packaging using a packaging film with tension lines and balanced stress lines.
[0022] In the figure:
[0023] 1: Packaging film, 2: Pull line, 3: Balance stress line. Specific implementation method:
[0025] The present invention will be further described below in conjunction with the accompanying drawings.
[0026] Embodiment 1
[0027] like Figure 1 As shown, the present invention provides a method for manufacturing a packaging film with a printed draw line.
[0028] 1) Production of packaging film: According to the process requirements of the product, produce packaging film that meets the standards; the packaging film adopts biaxially oriented POPP packaging film.
[0029] 2) Printing polyurethane ink lines: Print a polyurethane ink line parallel to the edge of the packaging film on the packaging film, the line width is 3-5 mm, the thickness is 20-50μm, the polyurethane ink line is dried and formed after printing and finally forms a pull line. When printing polyurethane ink, add " ” personalized information, forming a pull line with personalized information.
[0030] 3) Printing ordinary ink lines: Print an ordinary ink line parallel to the drawing line on the packaging film, the line width is 3-5 mm, the thickness is 20-50μm, and the ordinary ink line is dried and formed after printing and finally forms a balanced stress line.
[0031] The drawing line and the balanced stress line in the present invention are parallel to the edge of the packaging film, and the edge of the packaging film refers to the edge of the film in the length direction of the packaging film. The two ink lines are symmetrically arranged on the packaging film, and the distance between the two ink lines and the edge of the packaging film on the corresponding side is 1 / 3 of the width of the packaging film.
[0032] The present invention provides two ink lines, namely a draw line and a balanced stress line. After the packaging box is sealed, a U-shaped opening guide cut is provided at the draw line, and the cut coincides with the outer side of the draw line for tearing the draw line.
[0033] Balanced stress lines are used to reduce pressure. Because the polyurethane ink lines are directly printed on the surface of the packaging film, they will form bulges on the surface of the packaging film. When rolled, they will become higher and higher, which will affect the rolling of the packaging film and cause damage to the packaging film. Set the balanced stress lines symmetrically arranged with the tension lines. When the packaging film is rolled, there are two symmetrical bulges to avoid damage to the packaging film.
[0034] Embodiment 2
[0035] This embodiment provides packaging using a packaging film produced by the method of embodiment 1, such as Figure 1 As shown, the packaging box includes a packaging box body and a packaging film 1 coated on the packaging box body. A draw line 2 and a balance stress line 3 are provided on the packaging film 1. The draw line 2 and the balance stress line 3 are printed on the surface of the packaging film 1 and arranged along the circumference of the packaging box body. When packaging, the printed surface faces inward, and "XX series products" are displayed on the draw line 2. When packaging, a U-shaped opening guide incision is provided at the overlap of the film connecting the draw line 2, and the incision overlaps with the outer side of the draw line 2 for easy opening.
[0036] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
