Since the popularization of electronic products such as smartphones and tablets, tempered film has also risen; packaging is indispensable for the emergence of products, and natural tempered film packaging boxes have also evolved. Then what materials are mostly used for the tempered film packaging boxes?

1. White cardboard

White cardboard has firmness and thickness, high stiffness, good burst resistance and smoothness, and a smooth paper surface. The weight range of commonly used packaging materials is 250-400 grams of white cardboard, and 300 grams of white cardboard is generally used for packaging color boxes. White cardboard is not only easy to print, but the printed patterns are full and exquisite in color.

2. Coated paper (single powder)

The characteristics of coated paper are uniform thickness, small flexibility, high strength, good water resistance; paper surface wrinkles, perforations, etc.; paper uniformity and compactness, high whiteness, high smoothness and gloss on the paper surface, firm and consistent coating, After printing, you can get exquisite and clear patterns and characters; smooth and smooth, with high smoothness and good gloss. Single powder is a kind of cardboard with gray material made of recycled materials, and the printing effect is better with coating. Commonly used paper is 250-400g.

3. Kraft paper

Kraft paper has high tensile strength, high strength, and strong toughness. Kraft paper is generally brownish-yellow. We call it yellow kraft paper. It is resistant to tearing, cracking, and has high dynamic strength. It is widely used in shopping bags and packaging boxes. Because of its technological advantages, such as kraft paper is suitable for single-color printing and bronzing, silver bronzing, and other printing processes that are not very cumbersome. Commonly used paper weighs 250-450g kraft paper.

4. Greyboard paper

Gray board paper has good elongation, burst resistance, rigidity, folding resistance, and tearing; gray board not only has anti-wear, anti-skid, but also can protect the product well in the process of circulation, and it will not be transported. The bumps in the process caused the product to bump. However, if cardboard is generally used as the packaging of the tempered film, a layer of paper is usually mounted on the surface of the packaging box.

Of course, in addition to the above packaging materials, we also have types like acrylic boxes, which are all very protective.
