Among the four major packaging materials of paper, plastic, metal and glass, paper packaging materials are cheap and recyclable, which is conducive to environmental protection, so they develop rapidly.

There are also many products suitable for carton packaging, such as common medicines, food, cosmetics, tobacco, home appliances, hardware, glassware, ceramics, electronic products, etc.

In terms of structural design, the carton should be changed according to the packaging requirements of different products. For example, in the same drug packaging, the requirements for the packaging structure of tablets and bottled potions are quite different. Bottled potions need high-strength extrusion-resistant cardboard combined with a firm structure to form a protective layer. Fixing the bottle device, the size of the outer packaging has a lot to do with the specifications of the bottle. Some packaging cartons are thrown away after one use, such as household tissue boxes, which do not need to be extremely firm, but need to use paper products that meet the requirements of food hygiene packaging to make boxes, and they are also very economical in terms of cost.

Tobacco boxes are representative in terms of materials and craftsmanship. Rigid cigarette packs use high-grade white cards and have a fixed structure and size. In terms of printing technology, many manufacturers choose more reliable anti-counterfeiting printing and cold foil technology. Therefore, the printing materials and printing process with bright and bright colors and difficult anti-copying technology are more sought after by tobacco dealers.

There are many types of cardboard, and the thickness is generally between 0.3~1.1mm.

Corrugated cardboard: It is mainly composed of two parallel flat sheets as outer paper and inner paper, sandwiched between corrugated corrugated core paper processed by corrugating rollers, and each paper sheet is bonded with the corrugated paper coated with adhesive on the corrugated peak.

Yellow cardboard refers to the low-grade cardboard made from the pulp produced by the lime method with straw as the main raw material.

Kraft paperboard: It is made of kraft pulp. The one with kraft pulp on one side is called single-sided kraft board, and the one with kraft paper on both sides is called double-sided kraft board. The main function of corrugated cardboard surface paper is called kraft box board, and its strength is much higher than that of ordinary surface paper board. In addition, it can also be combined with water-resistant resin to make water-resistant kraft cardboard, which is mostly used in beverage collection boxes.
