Packaging cartons are a common type of packaging in paper product packaging and printing;
The materials used include corrugated paper, cardboard, gray baseboard, white cardboard and special art paper, etc.;
Some also use cardboard or multi-layer lightweight embossed wood board combined with special paper to obtain a more solid support structure.
There are also many products suitable for paper box packaging, such as common medicines, foods, cosmetics, home appliances, small hardware, glassware, ceramics, electronic products, etc.
In terms of structural design, paper boxes should be changed according to the packaging requirements of different products.
For the same pharmaceutical packaging, the requirements for packaging structure of tablets and bottled medicine are very different. Bottled medicine requires high-strength, squeeze-resistant cardboard combined with a solid structure to form a protective layer.
Its structure is generally a combination of inside and outside, and the inner layer usually uses a fixed medicine bottle device. The size of the outer packaging is closely related to the specifications of the bottle.
Manufacturers produce packaging cartons for household tissues that are cost-effective and meet food hygiene standards, ensuring they are not excessively strong but suitable for single use.
Cosmetic packaging boxes are representatives of exquisite materials and craftsmanship.
Hard box packaging uses high-grade white card with fixed structure and size;
In terms of printing technology, many manufacturers choose more reliable anti-counterfeiting printing, cold foil technology, etc.;
Therefore, printing materials and printing processes with bright colors and high-difficulty anti-copying technology are more popular among cosmetics manufacturers.
Paper boxes also use more complex structures and a variety of materials, such as various gift packaging, high-end tea packaging, and even the once popular Mid-Autumn Festival gift cake packaging cartons;
Some packaging is to protect the product more safely and highlight its preciousness and luxury, while others are packaging just for packaging, which does not meet the practical functions of packaging described below.
In terms of the materials used for paper boxes, cardboard is the main material.
Paper with a basis weight of more than 200gsm or a thickness of more than 0.3mm is generally called cardboard.
The raw materials for cardboard are basically the same as those for paper. There are many types of cardboard, and the thickness is generally between 0.3 and 1.1mm.
Corrugated cardboard:
It mainly consists of two parallel flat sheets of paper as outer and inner paper, with corrugated core paper processed by corrugating rollers in the middle. Each paper sheet is bonded to the corrugated paper with adhesive applied to the flute.
Manufacturers use corrugated board to create outer packaging boxes that protect goods during transportation, while finer corrugated paper is used as inner cushioning to reinforce and safeguard the items inside. There are many types of corrugated paper, including single-sided, double-sided, double-layer and multi-layer.

White paperboard is made of chemical pulp and high-grade pulp.
There are ordinary white paperboard, white paperboard, kraft paperboard, etc. Manufacturers create high-grade white paperboard, made entirely from chemical pulp and commonly known as white cardboard.
Yellow paperboard refers to low-grade paperboard made of pulp produced by lime method with straw as the main raw material. Companies use it primarily as the box core in paper boxes to secure and stabilize the packaging.
Kraft paperboard:
Made of sulfate pulp. Manufacturers refer to paperboard with one side covered as single-sided kraft paperboard, and paperboard with both sides covered as double-sided kraft paperboard.
Manufacturers use kraft paperboard as the main material for corrugated paperboard because it is significantly stronger than ordinary paperboard. In addition, it can also be combined with water-resistant resin to make water-resistant kraft paperboard, which is mostly used for beverage packaging boxes.
Composite processed paperboard:
refers to paperboard made of composite aluminum foil, polyethylene, oil-proof paper, wax and other materials. It makes up for the shortcomings of ordinary paperboard and makes the packaging paper box have many new functions such as oil-proof, waterproof and fresh-keeping.
