Types of materials used for packaging mainly include paper, plastic, metal, grass, composite flexible packaging, and other packing materials like wood. The quality and rigor of the packaging determine the goods’ quality when we sign it. And packaging is vital in the entire packaging, express, and shipping. Then, they can improve economic development and reduce packaging costs. So what are the common types of materials used for packaging? Next, let’s see it.

1. Paper packaging materials

Corrugated paper

Corrugated paper is lightweight and low in cost. Then, it is easy to process and has high strength. Besides, it is convenient for storage and handling. Thus, we can use it to package food, digital products, and daily necessities. More than 80% of corrugated paper can be recycled. In addition, it is relatively eco-friendly.

Containerboard paper (kraft paper, kraft cardboard)

The paper is a tough texture with high burst and tear resistance. So, we make it into corrugated boxes after bonding with corrugated cardboard cores. In addition, it is a common packaging paper type. Such as household appliances; daily department stores; knitted cotton fabrics; stationery, etc.

Whiteboard

Whiteboard (printing) is suitable for single-sided color printing. And then we can make it into cartons for packaging. Or we use it for design and handmade products. Then, whiteboard suits seminars, workshops, conferences, etc.

White cardboard

Gold and silver cardboard

They have wide use in color printing packaging. And I think it is suitable for box-making printing. Then, it has a wide range of use in daily life. Such as cigarettes, alcohol, food, cosmetics, toothbrush boxes; medicine, and gift bags.

Then, the surface of the paper can produce a beam of light with the effect of laser paper. But, most of the gold and silver cardboard used are acquired composite materials with film as the medium.

Greaseproof paper (translucent paper, glossy paper)

Wax paper can wrap hamburgers, bake bread, biscuits, and other food and other oily items. It has high strength and paper smoothness. But the air permeability is low. The transparency of the paper sheet is high, which prevents the penetration and absorption of grease. However, it is important to note that this paper is only for one-time use.

Cellophane paper

Cellophane is a thin transparent wrapping material made from viscose. It can be used as lining paper and decorative wrapping paper for merchandise. Not only can it be moisture-proof, but also heat-sealed. At the same time, it has the advantages of no static power and dust. But this paper can not deform at a high temperature of 190 °C. So we can pasteurize with food in food packaging.

Aluminum foil paper

The aluminum foil paper is soft and easy to deform and does not rebound after deformation. Meanwhile, it can block light, no pollution, and the price is cheap. Thus, we can use it to package and decorate cigarettes, candies, and other foods. But we note that tin foil belongs to the metal category. Chemical changes occur when metals are mixed with acidic substances. It is easy to produce carcinogens that are harmful to humans.

2. Plastic packaging material

Packing belts
