Problems solved by technology

However, Document 2 does not pay attention to the tearable zipper structure, nor does it involve the smoothness, aesthetics, safety and other factors of packing box disassembly
In addition, although Document 2 involves the functions of fresh-keeping and moisture-proof, it does not give specific fresh-keeping and moisture-proof components, and does not conduct in-depth research on the comprehensive performance of cartons, which will be used for high-end specific purposes in packaging cartons (for example, environmental Harsh, high pressure transportation field, or precision instrument packaging and delivery field) there are deficiencies
[0006] For another example, Chinese patent application (document 3: CN1972846A) relates to a kind of packing carton, and it relates to and discloses a kind of top angle can be torn structure; Yet document 3 does not pay attention to the flatness of carton remaining part after the top corner is removed , strength, and the aesthetics and durability of the remainder as a packaging structure for long-term storage

Embodiment 1

[0035] Boards suitable for making paper packaging boxes can be obtained from commercial or other sources, and laser perforation technology is used to make two rows of holes arranged in a straight line on the paper board in a straight line, as the part to be torn off of the carton.

[0036] Here, without limitation, the laser perforation process may be an existing industrialized laser perforation process, or a laser processing process disclosed in other documents (for example, Chinese patent document CN103274092A). During the processing, the distance between two rows of holes is 10 mm, the diameter of each hole is set to 1.0 mm, and the hole spacing is set to 0.5 mm; the holes are circular.

[0037] The prepared carton before folding is in figure 1 visible in . It can be seen from the figure that the position 1 marked by the two thinner lines indicated by the arrow represents the prepared carton. figure 1 Only one closely-arranged hole (that is, the part to be torn) that has ...

Embodiment 2

[0041] Adopt similar preparation process and steps as in Example 1, but the difference is that for the hole diameter, the spacing between adjacent holes and the width (D1) of the discarded part after tearing and the height (D2) of the carton The preferred scheme has been implemented.

[0042]Specifically, the inventors found through repeated research that although the size of the carton may vary according to the application, the hole diameter, the spacing between adjacent holes, and the discarded part are essential for the flatness and strength of the torn carton A better technical solution can be obtained by setting the ratio of the width and height of the carton. Without limitation, for example, in a specific preparation process, when the diameter of the holes is 0.15-0.19mm, and the spacing of the holes is 0.1-0.5mm, better packaging box flatness after tearing is obtained; and in the tearing process Among them, the tearing force used by the user is moderate, and the streng...

Embodiment 3

[0049] This embodiment uses a process similar to that of Embodiment 1, the difference is that this embodiment focuses on the composite structure and composition of the packaging carton.

[0050] In this embodiment, the sheet material of the paper packaging box is provided, the sheet material used (and the corresponding carton structure finally prepared) includes a face paper layer, a core paper layer and a protective layer; (optionally the face paper layer and The adhesive layer between the core paper layers) and the protective layer includes a strength protective layer, a waterproof penetration layer and an oil-proof layer, and the strength protection layer, the waterproof penetration layer and the oil-proof layer are arranged on the face paper layer or the oil-proof layer of the carton in sequence on top of the core paper layer. The strength protection layer can adopt such as metal mesh (such as steel wire mesh), fiber mesh, acrylic board; the waterproof layer can adopt alum...

Abstract

The invention provides a zipper type paper box enabling a tearing edge to be smooth and a manufacturing method of the zipper type paper box. In a paper packaging box, the zipper type paper box is provided with a to-be-torn part which is provided with two columns of holes arranged in a linear shape. The holes are the same in diameter, and the adjacent holes are spaced with the same interval. The diameter of the holes of the to-be-torn part ranges from 0.02 mm to 3 mm, and the distance between every two holes ranges from 0.1 mm to 5 mm. The invention further relates to the packaging box with specific structures and components such as a waterproof layer with the specific component, an oil-proof layer with the specific component and a strength improving layer with the specific component. By means of the paper packaging box, it can be ensured that the tearing edge of the tearing part is smooth through the paper box with the components, water resistance (damp resistance), oil stain prevention and enough strength are achieved at the same time, and the specific gravity of the paper box is kept reasonable.

Description

technical field [0001] The invention relates to the field of paper packaging, more specifically, the invention relates to a zipper type carton capable of making the tearing edge smooth and a manufacturing method thereof. Background technique [0002] With the development of Internet technology, under the background of the country's policy of vigorously supporting Internet + and the development of the industry economy, the logistics field has also grown rapidly and vigorously. In the field of logistics, whether wholesale or retail, paper packaging is an indispensable part of the logistics industry. Many factories, enterprises, and engineering research units are trying to find and meet the industrial production and use standards, and have a composite multifunctional excellent performance and acceptable cost of the paper packaging structure. [0003] In the field of logistics and distribution, tearable zipper cartons have always been one of the paper packaging with the greates...
