Packaging box production

What is the printing process for packaging box production? As we all know, the production of packaging boxes is a complex process, which is different from general standard parts products. Generally, customization is required, and a single box of packaging needs to go through several processes to be made.

What is the process flow? 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

Premium buckle special paper card box

Color boxes are divided into two categories:

Face paper, pit paper. The commonly used color box surface paper includes: gray paper, white card, copperplate, special paper, gold card, silver card, laser card, kraft paper, etc.

The post-processing of gold and silver cardboard packaging boxes is generally completed by printing - surface finishing (hot stamping, silver stamping, film covering, local UV, embossing, etc.) - die cutting - box pasting - inspection - packaging.

The production process of the card box is carried out by printing, surface finishing, outsourcing material die-cutting, mounting card paper, mounting corrugated paper, automatic box pasting machine for card box bonding, inspection, and packaging completion.

Most of the high-end card boxes commonly found in our daily lives are made of paper, and the surface of paper is also most suitable for applying more processing techniques. Therefore, we will use paper as the fabric for the following

A process description.

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 Hot stamping (gold, red gold, colored gold, silver, laser, etc.);

④ Scrape UV oil or screen ink locally;

⑤ Special Colorful Powder;

⑥ Convexity;

⑦ Embossing and so on.

White cardboard

Material characteristics: White cardboard is sturdy and thick, double-sided white, with high stiffness, durability and smoothness. The paper surface is flat, and the commonly used thickness is 190-400 grams of white cardboard

The printed color is full and the texture is very good.

Whiteboard paper (gray background whiteboard)

Material characteristics: Whiteboard paper is a type of cardboard with a white and smooth front and a gray background on the back. The commonly used thickness is 250-400g, and one side of the whiteboard paper is white and the other side is gray.

Copperplate paper

Material characteristics: The characteristic of copperplate paper is that the paper surface is very smooth and flat, with white on both sides, good glossiness, and it also gives the printed graphics a three-dimensional sense. The commonly used thickness is 128-350 grams, and copper

The printing effect of the plate paper is the same as that of white cardboard, with full and bright colors, but the stiffness is not as good as that of white cardboard. Generally, it needs to be mounted on cardboard or corrugated paper. Determine the material of the color box based on the shape and size of the product,

The commonly used materials include: 280G powder gray paper, 300G powder gray paper, 350G powder gray paper, 260G powder gray paper mounting E-pit, 260G double powder paper mounting E-pit

Corrugated paper

Material characteristics: The surface is made of white board paper, and the surface paper is stronger and thicker than the surface corrugated bottom paper box. The resistance to breakage and pressure is greatly increased, which can load heavier products. In addition, the corrugated paper box has

A certain degree of shock and pressure resistance function, with stronger protection ability, can better protect new products inside.

Gold and silver cardboard

Material characteristics: Gold and silver cardboard is a special type of paper, which is divided into two types: glossy gold cardboard and matte gold cardboard, glossy silver cardboard and matte silver cardboard; It has a very high glossiness, bright colors, and full layers,

The surface produces light columns that have the effect of laser paper. The packaging box made of it has the characteristics of waterproofing, corrosion resistance, and wear resistance.

Special paper

Material characteristics: Special paper is made from surface slurry and various layers of bottom slurry. So pulp is generally divided into surface layer, second layer, third layer, and fourth layer, and the fiber ratio of each layer of pulp is different

Similarly, the fiber ratio of each layer of pulp varies depending on the quality of the paper being made.

Special paper is a relatively high-end packaging paper that prints various trademarks and packaging boxes, such as children's toys, medicines, food, cigarette boxes, toothpaste, gift boxes, etc.

Special paper is relatively unique compared to other types of paper. When printing, it is necessary to pay attention to the characteristics of special paper itself, print the printed material well, and not waste paper or cost in vain.
