Raw Materials Needed For Packaging Box Color Printing

The raw materials needed in the color printing of packaging boxes mainly include paper, ink and possible auxiliary materials. The following is a detailed description of these raw materials:

1. Paper

Paper is the basic raw material in the color printing of packaging boxes. It has many types and characteristics, suitable for different packaging needs and design styles.

Common paper raw materials include:

Cardboard:

Cardboard is one of the commonly used materials in the color printing of packaging boxes. Its gram weight is generally between 250g and 450g. The specific choice depends on the customization needs and design effects of the packaging box.

The surface of the cardboard is smooth and the printing effect is good. It is suitable for making various exquisite packaging boxes.

Corrugated paper:

Corrugated paper is widely used in the packaging field for its unique structural characteristics.

It is usually made of surface paper, inner paper, core paper and corrugated paper processed into corrugated corrugated paper by bonding, and has good compressive strength and cushioning performance.

In the color printing of packaging boxes, corrugated paper is often used to make packaging that requires certain load-bearing and protective performance.

Gray board paper: Gray board paper is generally used to make high-quality packaging boxes. Its gram weight is usually above 800g (1mm) and has high hardness and stiffness. The surface of gray board paper can be processed in many ways, such as lamination, hot stamping, etc., to enhance the texture and aesthetics of the packaging box. White board paper: White board paper is a kind of paperboard with a white and smooth front and a gray back. It has good printing adaptability and stiffness, and is suitable for single-sided color printing and then made into paper boxes for packaging. White board paper also occupies an important position in packaging box color printing. Coated paper: Coated paper, also known as printed coated paper, is made by coating a layer of white wax paper on the base paper. It has a smooth surface, high whiteness, good ink absorption and ink receiving state, and is very suitable for printing high-quality pictures and text content. In packaging box color printing, coated paper is often used to make the cover and illustration part of high-end packaging boxes. 2. Ink Ink is one of the indispensable raw materials in packaging box color printing. It is responsible for transferring patterns, text and other content to paper to form the visual effect behind.

In packaging box color printing, commonly used ink types include:

Environmentally friendly ink:

With the improvement of environmental awareness, more and more packaging box color printing manufacturers have begun to use environmentally friendly inks for printing.

Environmentally friendly inks have the characteristics of low volatility and low toxicity, and have little impact on the environment and human health.

UV ink:

UV ink is an ink that is cured by ultraviolet rays.

It has the advantages of fast drying speed, bright colors, and strong wear resistance, and is very suitable for high-precision printing needs in packaging box color printing.

3. Auxiliary materials

In addition to paper and ink, some auxiliary materials may be involved in the color printing of packaging boxes, such as:

Glue:

Glue used to bond paper and other raw materials into packaging boxes is also one of the important auxiliary materials.

When choosing glue, you need to consider its adhesion, environmental performance and whether it is suitable for the characteristics of the paper used.

Laminating materials:

In order to improve the waterproof, moisture-proof and wear-resistant properties of the packaging box, a film is sometimes applied to the surface of the packaging box.

The choice of laminating materials should be considered according to specific needs and budget.

In summary, the raw materials needed in the color printing of packaging boxes mainly include paper, ink and possible auxiliary materials such as glue and laminating materials.

When choosing these raw materials, you need to consider multiple factors such as packaging needs, design effects, cost budget and environmental protection requirements.
