Corrugated paper

Corrugated paper is a plate-shaped object formed by the bonding of hanging paper and corrugated paper processed by corrugated roller. It is generally divided into single corrugated board and double corrugated board. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability and convenient storage and handling. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as the packaging of food or digital products, which is relatively environmentally friendly and widely used.

Usage

Type a corrugated and type B corrugated are generally used as transportation outer packing boxes, and beer boxes are generally made of B corrugated. E-shaped corrugated is mostly used as a single packing box with certain aesthetic requirements and appropriate weight contents. F-shaped corrugated and G-shaped corrugated are collectively referred to as micro corrugated. It is an extremely thin corrugated, which is used as a disposable packaging container for hamburgers, cream filled pastries and other foods, or as the packaging of micro electric products such as digital cameras, portable music centers and refrigerated commodities.

Cardboard

Cardboard began at the end of the 18th century. At the beginning of the 19th century, its application has increased significantly because of its light weight, low price, wide range of uses, simple manufacture, and can be recycled or even reused. By the beginning of the 20th century, it had been popularized, popularized and applied to make packaging for all kinds of commodities. Because the packaging container made of cardboard has its unique performance and advantages in beautifying and protecting the inner goods, it has achieved great success in the competition with a variety of packaging materials. So far, it has become one of the main materials for making packaging containers with long-term use and rapid development. Cardboard is made of face paper, lining paper, core paper and corrugated paper processed into waveform corrugated by bonding. According to the demand of commodity packaging, cardboard can be processed into single-sided cardboard, three-layer cardboard, five layer, seven layer and eleven layer cardboard. Single sided cardboard is generally used as the lining protective layer of commodity packaging or to make light grids and backing plates to protect commodities from vibration or collision during storage and transportation. Three-layer and five-layer cardboard are commonly used in making corrugated boxes. The packaging of many goods is simple and exquisite through three or five layers of cardboard. Beautiful and colorful graphics and pictures are printed on the surface of corrugated box or corrugated box, which not only protects the internal goods, but also publicizes and beautifies the internal goods. The cardboard on the seventh or eleventh floor is mainly used to make packaging boxes for Electromechanical, flue-cured tobacco, furniture, motorcycles, large household appliances, etc.

Corrugated box

Corrugated box is made of cardboard. It is the most widely used paper container packaging and is widely used in transportation packaging. Corrugated box is widely used because it has many unique advantages: ① good cushioning performance. ② Light and firm.③Small overall dimensions. ④ Sufficient raw materials and low cost. ⑤ It is convenient for automatic production. ⑥ Low packaging cost. ⑦ Can pack a variety of items. ⑧ Less metal. ⑨ Good printing performance. ⑩ Recyclable and reusable.

Composite plate

Corrugated composite board is a new type of material that is emerging after the introduction of honeycomb paperboard in the United States and Europe. It is a new generation of high-tech achievement with complete intellectual property rights from the whole automatic production line equipment to finished products in China. The finished products have the advantages of light weight, high strength, no deformation, good rigidity, strong cushioning performance, good sound insulation and heat insulation effect. After proper treatment, they can be flame retardant, moisture-proof and waterproof. Moreover, the requirements for raw materials are lower than those of honeycomb paperboard. Recyclable waste paper and old corrugated boxes are used as production raw materials, so the sources of raw materials are wide and sufficient. The finished products can be recycled after use, which meets the environmental protection requirements of resource recycling and has a very wide application prospect. Corrugated composite board can be made into packing boxes and liners of various precision instruments, electromechanical equipment, household appliances and ceramic products, as well as pallets, cushion liners and aviation turnover boxes of various specifications; In terms of building materials, corrugated composite board can be used to make light partition wall, sound insulation board, temperature insulation board, furniture and export disposable beach dining table, as well as the emerging sanitary sterile paper coffin for cremation.
