XIAMEN SUNBOO PACKAGING

To a large extent, the rigid box uses its exquisite shape and decoration to promote and beautify the product and improve the competitiveness of the product. Since the shape and structural design of rigid box are often determined by the shape and characteristics of the packaged goods, there are many styles and types, such as rectangles, squares, polygons, special-shaped cartons, cylinders, etc., but the manufacturing process is basically the same. .

Rigid box  production process

①Selection of paper

Consider the paper type, such as coated paper, fine art paper, pearlescent paper, etc.

Consider the thickness of the paper, and be careful not to make the paper too thick, otherwise the paper will wrinkle easily, and it should not be too thin, otherwise the embossing effect will not be reflected.

②Surface finishing

Glazing, reverse glazing, lamination (glossy film, matte film, tactile film, scratch-resistant film, etc.), embossing, hot stamping (gold, red gold, colored gold, silver, laser, etc.), partial UV

③ Gray board selection

Gray board is produced from a kind of recycled waste paper, mainly divided into single gray, double gray, full gray, high gloss, according to the customer's requirements for surface smoothness. Gray paper is an environmentally friendly packaging material. In special cases, there is no upper limit. Usually, gray boards of appropriate specifications are selected according to the specifications of the gift box.

④Die cutting

Rigid box  have high technical requirements for die-cutting. The precision and accuracy of die-cutting directly affect the processing quality of subsequent processes and will directly determine the quality of products.

Die-cutting is a very important link in the manufacturing process, especially for gift packaging boxes, which have higher technical requirements for die-cutting. Precision and accuracy determine the quality of products, and slight errors directly affect the quality of subsequent processing. The terminology of die-cutting process name is;

4.1. Half-piercing (half-cutting): Cut out a line or a line of any shape with a depth not less than two-thirds of the thickness of the material on the cardboard or gray board with a die-cutting knife.

4.2. Die-cutting creasing: When die-cutting the gray board, make a positioning mark, usually add a half-piercing knife or a trace line, which is convenient for positioning when pasting.

⑤ Grooving

gray board slotting

Slotting is a key step in the production of Rigid box . Before the gray board is formed, the gray board must be removed in a V shape, so that after the gray board is bent, the outside is straight and the inside is square, with clear edges and corners, and the four corners match accurately. The term name for is;

5.1. Grooving: Use a slotting machine to open a V-shaped groove on a gray board with a thickness of 1--4MM, and generally keep a connection layer of about 0.25MM.

5.2. Groove angle: V-groove has an angle, generally 90 degrees, 120 degrees, or V-groove with different angles according to the product structure.

Note: After the gray board is bent, it must be straight on the outside and square on the inside, with sharp edges and corners, and the four corners match accurately.

⑥Paper

Assembly process

Mounting is a necessary process in the Rigid box  process. According to different product requirements, the coated paper, art paper, flannelette, leather, etc. are glued or sprayed through the glue machine, and the gray board is tightly pasted together, so that the two are combined into one, so that the gray board The surface "renews the gray appearance", which not only beautifies the appearance of the box body, but also increases the added value of the packaging box.
