Type A corrugated and type B corrugated are generally used as outer packaging boxes for transportation, and beer boxes are generally made of B corrugated. E-type corrugation is mostly used as a single-piece packaging box with certain aesthetic requirements and suitable weight of contents. F-type corrugation and G-type corrugation are collectively called micro-corrugation. It is an extremely thin corrugation and is used for food such as hamburgers and cream-filled pastries. disposable packaging containers, or used as packaging for microelectronic products such as digital cameras, portable stereos, and refrigerated commodities.
cardboard
Corrugated cardboard began in the late 18th century. In the early 19th century, its application grew significantly because of its light weight, low price, wide range of uses, easy production, and the ability to be recycled or even reused. By the beginning of the 20th century, it had been fully popularized, promoted and applied for packaging a variety of commodities. Because packaging containers made of corrugated cardboard have unique properties and advantages for beautifying and protecting the goods inside, they have achieved great success in competing with a variety of packaging materials. It has become one of the main materials for making packaging containers that has been used for a long time and has shown rapid development.
Corrugated cardboard is made of top paper, lining paper, core paper and corrugated paper processed into corrugated corrugated sheets through bonding. According to the needs of product packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer and other corrugated cardboard (as shown in Figures 1 and 2). Single-sided corrugated cardboard is generally used as a lining protective layer for commodity packaging or to make lightweight frames and pads to protect commodities from vibration or collision during storage, transportation, and three-layer and five-layer corrugated cardboard are used in making corrugated boxes. common. Many products are packaged simply and beautifully using three- or five-layer corrugated cardboard. Beautiful and colorful graphics and pictures are printed on the surface of corrugated boxes or corrugated boxes, which not only protects the inner goods, but also promotes and beautifies the inner goods. commodity. Many corrugated boxes or corrugated boxes made of three-layer or five-layer corrugated cardboard have been directly put on the sales counter and become sales packaging. Seven-layer or eleven-layer corrugated cardboard is mainly used to make packaging boxes for mechanical and electrical appliances, flue-cured tobacco, furniture, motorcycles, large household appliances, etc. For specific products, this corrugated cardboard combination can be used to make inner and outer boxes, which is convenient for production and convenient for the packaging, storage and transportation of the products. With the needs of environmental protection and the requirements of relevant national policies, commodity packaging made of corrugated cardboard has a tendency to gradually replace wooden box packaging.
carton
Corrugated boxes are made of corrugated cardboard and are the most widely used paper container packaging and are widely used for transportation packaging. The reason why corrugated boxes are widely used is that they have many unique advantages: ① Good buffering performance. ②Lightweight and strong. ③Small appearance size. ④Sufficient raw materials and low cost. ⑤ Convenient for automated production. ⑥The packaging operation cost is low. ⑦Can pack a variety of items. ⑧The amount of metal used is small. ⑨Good printing performance. ⑩ Can be recycled and reused.
Composite board
Corrugated composite board is a new material that is emerging after the introduction of honeycomb paperboard in the United States and Europe that saves resources, protects the ecological environment, and is relatively low-cost. It is a new generation of high-tech materials that China has complete intellectual property rights from the entire automatic production line equipment to finished products. Technological Achievements. Its finished products are light in weight, high in strength, non-deformable, good in rigidity, strong in buffering performance, and have good sound and heat insulation effects. They can be flame retardant, moisture-proof, and waterproof after proper treatment. They have lower raw material requirements than honeycomb cardboard and can be recycled. Paper and old corrugated boxes are used as raw materials for production, so the sources of raw materials are wide and sufficient. The finished products can be recycled and reused after use, which meets the environmental protection requirements of resource recycling and has extremely broad application prospects. Corrugated paper composite boards can be made into packaging boxes and liners for various precision instruments, mechanical and electrical equipment, household appliances, ceramic products, etc. They can also be made into pallets, cushion liners, and aviation turnover boxes of various specifications; corrugated paper is used in building materials Composite panels can be used to make lightweight partition walls, sound insulation boards, heat insulation boards, furniture, disposable beach tables for export, etc. They can also be used to make the emerging sanitary and sterile paper coffins for disposable cremations.
