What Are The Raw Materials Needed For Color Printing Of Food Packaging Boxes?

The raw materials required for color printing of food packaging boxes mainly include paper, ink and other possible auxiliary materials.

The following is a detailed description of these raw materials:

1. Paper

Paper is the basic material for color printing of food packaging boxes. Common paper materials include:

White cardboard:

The front is smooth and bright, with high stiffness and folding resistance, the back and the middle are white, suitable for high-end food packaging.

Gray cardboard:

The front is white, relatively flat and smooth, the bottom is gray, the middle is gray, the stiffness is good, the price is cheap, and it is also suitable for food packaging.

White board paper:

The front is white and smooth, the back is mostly gray, the texture is hard and thick, with good standing strength, surface strength, folding resistance and printing adaptability, suitable for making food packaging boxes.

Kraft paper:

The paper surface is smooth, the color is pure, the paper has good stiffness, high tear resistance, and has good folding resistance and water resistance. It is also commonly used in food packaging.

2. Ink

Ink is the key raw material for color printing of food packaging boxes, used to present various colors and patterns on paper.

The selection of ink needs to take food safety into consideration, so inks that meet food grade standards are usually selected.

These inks should have good printing adaptability, drying speed and color vividness.

3. Auxiliary materials

In the process of color printing of food packaging boxes, some auxiliary materials may also be used, such as:

Varnish:

Used to increase the gloss and wear resistance of the packaging box surface.

Matt oil:

Used to make matte effect packaging boxes to make the surface softer.

Bronzing materials:

Used to add gold or other colors of metallic luster to the packaging box to enhance the overall sense of grade.

Laminating materials:

Such as PET film, PP film, etc., used to increase the waterproof and moisture-proof properties of the packaging box.

4. Environmental protection and sustainability

When choosing raw materials for color printing of food packaging boxes, environmental protection and sustainability must also be considered.

For example, you can choose recyclable paper materials, use environmentally friendly inks, and reduce the use of auxiliary materials.

These measures help reduce pollution to the environment and achieve green packaging.

In summary, the raw materials required for color printing of food packaging boxes mainly include paper, ink and auxiliary materials.

When selecting these raw materials, it is necessary to comprehensively consider factors such as product characteristics, safety, environmental protection performance and sustainability.
