Packaging box

What is the printing process for packaging box production? As our peers know, the production of packaging boxes is a complex process, and people from different industries generally believe that if they ask you to make production today, they will receive it immediately tomorrow. Every other industry has its own workflow, and a grid of packaging needs to go through several processes. What is the printing process for packaging box production at Shenzhen Jinyang Huayu Paper Products Co., Ltd? Below is a brief and specific introduction for everyone.

First, communicate with the client mainly about whether design is needed, what kind of material requirements and how much quantity is needed, and then provide the client with a quotation. If the client is satisfied, proceed to the next step

Special shaped gold and silver cardboard double open box gift box

The production process of high-end gold and silver cardboard gift boxes is much more complex than that of ordinary packaging boxes. The subsequent processing of ordinary packaging boxes is generally completed by printing - surface finishing (hot stamping, silver stamping, film covering, local UV, embossing, etc.) - die cutting - pasting the box - inspection - boxing.

The production process of gift boxes involves printing, surface finishing, outsourcing material die-cutting, gray board die-cutting, gray board slotting, gray board forming, outsourcing material pasting, assembly, inspection, and packaging. From the process of the two products, the production process of gift boxes is complex and cumbersome, and the process standards are far higher than ordinary packaging boxes.

Most of the high-end gift boxes commonly found in our daily lives are made of paper, and the surface of paper is also most suitable for more technological processing. Therefore, the following is a process explanation using paper as the fabric.

01 Paper selection

The selection of paper is crucial based on the client's document design requirements and the desired effect to be reflected. The main considerations in this regard are:

① Is the type of paper used, such as gold and silver cardboard, copperplate paper, art paper, or pearl paper?

② The thickness of the paper. The paper should not be too thick, as it is prone to wrinkling when pasted, but it should not be too thin, otherwise the convex effect cannot be reflected.

③ Consider the decorative effect on the surface.

02 Surface decoration

There are many surface decoration processes, the most common of which are (7+1) (8+1) UV printing, and various processes based on this include:

① Reverse polishing;

② Coating (light film, matte film, tactile film, scratch resistant film, etc.);

③ Scrape UV oil or screen ink locally;

④ Special Colorful Powder;

⑤ Convexity;

⑥ Embossing and so on.

03 Selection of gray cardboard

Grey cardboard, abbreviated as grey cardboard, is produced from a type of recycled waste paper. It is mainly divided into single gray, double gray, full gray, and high gloss, depending on the customer's requirements for surface smoothness. Belonging to environmentally friendly packaging materials, the quantity ranges from 250g to 10000g, and the thickness ranges from 0.4mm to 20mm. There is no upper limit on the thickness and quantity, and the appropriate size of the gray board card is usually selected based on the size of the gift box.

04 die-cutting

Die cutting is a very important part of the manufacturing process, especially for gift packaging boxes, which require higher technical requirements for die cutting. Precision and accuracy determine the quality of the product, and slight errors directly affect the quality of subsequent processing.

05 slotting

Slotting is the process of using a slotting machine to create a V-shaped groove on a 1-4mm thick gray board, usually retaining a connecting layer of about 0.25mm. The V-shaped groove has angles, usually 90 degrees or 120 degrees, or different angles can be created according to the product structure. Slotting is a crucial step in the production of gift boxes. Before forming the gray board card, it must be removed in a V-shape to achieve a straight outer and square inner shape, clear edges, and precise matching of the four corners after the gray board card is bent.

06 Pasting

Mounting is a necessary process in gift box craftsmanship. It involves gluing or spraying copperplate paper, art paper, velvet cloth, and leather materials through a gluing machine according to the requirements of different products, and tightly sticking them together with the gray board to merge them into one. This not only beautifies the appearance of the box, but also increases the added value of the packaging box.

The usual packaging boxes are first laminated and then die cut, but for laminated gift boxes, die cut and then laminated are used. The purpose of this is to prevent contamination of the outer packaging material, which may affect the appearance; Secondly, the gift box emphasizes the overall harmony of the effect, and only by mounting it can the supporting body be completely covered, so that the gray of the gray board is wrapped in innovative packaging materials, presenting us with a beautiful artwork; The third is some complex box shapes that still cannot be separated from manual pasting. This is not something that machines cannot replace, but rather manual pasting is necessary to ensure that every detail of the box body is glued in place, making the outer laminating paper and the gray board stick more tightly.
