Foldable box how to make ?

Background Technology:

With the rapid development of modern business, the global packaging industry demand is growing steadily. In the packaging industry, paper packaging is used more and more widely because of its good physical and mechanical properties, decoration and printing adaptability, economic practicability and environmental protection, product sales continue to grow, and the demand for packaging boxes will also increase, customers often put forward to ensure beautiful and delicate structure, and then optimize to reduce costs.

There are two kinds of analysis on the existing packaging: the first one is the grey board covered by facial paper, which is made by the following three kinds of processes. 1. Usually, the gray board of the world box will be made by the process of slotting or half wearing. The surface paper will be wrapped by 157-180G thin paper + gray board slotting. 2. The same 300G material slotting + grey plate semi-piercing production, although the box type achieves beautiful and delicate effect, but the face paper needs to open 12 slots, the process is more difficult, and the loss cost is increased in all aspects; 3, the use of heaven and earth box packaging materials (gray plate + face paper) form, prone to gray plate material thickness inconsistency, slotting size error, the production process box will be tilted from the bottom to the outer 91 degrees, after assembly tightness from the original 0.5mm into the top 0.2mm, the bottom gap to 0.8mm, affecting the appearance and assembly function. The second is pit box folding molding, using thick paper (190-450g powder and ash, single powder) to mount pit paper, the surface of the finished product is easy to appear pit grain, interface edge gap, round edge, inner pit grain is obvious, easy to have concave and convex fold imagination, not suitable for fine packaging.

Therefore, to provide a paper card folding box and day box gap uniform, uniform tightness effect, does not affect the appearance and assembly, has become an urgent problem to be solved in the field of packaging boxes.



Technical implementation elements:

The utility model aims to provide a cardboard folding box in which the first side plate, the second side plate and the second folding plate are treated with beveled edges, so as to solve the problem that the mouth edge deformation and expansion affect the appearance and assembly of the box body after forming.

The second purpose of the utility model is to provide a heaven and earth box, which solves the problem that the mouth edge deformation and expansion affect the appearance and assembly of the box body after forming.

To achieve this purpose, the utility model adopts the following technical scheme:

Among them, the Angle between the bottom edge of the second side plate and the side is 89°, and the Angle between the bottom edge of the second folding plate and the side is 91°.

Wherein, the surface of the first side plate and the first folding plate are provided with the first rubber layer.

Among them, the second folding plate inward folding toward the side of the second side plate is provided with a second rubber layer.

Among them, the length of the right side of the square bottom plate is greater than the sum of the lengths of the two inserts.

Among them, the surface of the cardboard folding box is provided with a coated layer.

The utility model has the following beneficial effects: The utility model provides the paper folding box, including square bottom, both side of square plate are in turn connected with the first side plate and the first folded plate, square plate before and after the two side are connected in sequence and the second side plate and the second folded plate, the second side panel are set on both sides of the board, the first of the lower side of the side plate and the side Angle is 87 ° ~ 89.5 °, The Angle between the bottom edge of the second side plate and the side is 87° ~ 89.5°, and the Angle between the bottom edge of the second folding plate and the side is 90.5° ~ 93°. The first folding plate is folded inward, and the insert plate is inserted between the first side plate and the first folding plate. The first side plate, the second side plate and the second folding plate do the beveled edge treatment. Among them, the Angle between the bottom edge of the first side plate and the side side is 87° ~ 89.5°, and the Angle between the bottom edge of the second side plate and the side is 87° ~ 89.5°. Second folded plate bottom and side Angle is 90.5 ° ~ 93 °, solve the molding box body after mouth deformation problem, affect the appearance and extension assembly with the box of top-down gap after assembly the same day, uniform elastic effect, in addition, using cardboard as the raw material, saves the routine use of (grey board + surface paper) materials, low prices, reduce costs, Simple structure, reduce the box body pollution components. The mouth edge of the paper folding box of the utility model is not easy to deform after forming, and the gap between the paper folding box and the day box is uniform after assembly, and the tightness effect is uniform, does not affect the appearance and assembly, and reduces the cost.
