what is corrugated paper?
Corrugated cardboard is made of face paper, lining paper, core paper and corrugated paper, and is processed into corrugated paper. The actual performance depends on three factors: the characteristics of the core paper and board and the structure of the carton itself.
Type of corrugated cardboard
According to the needs of commodity packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer, five-layer, seven-layer, and eleven-layer corrugated cardboard. Single-sided corrugated cardboard is generally used as a protective liner for commodity packaging or to make lightweight cardboard and pads to protect commodities from vibration or shock during storage and transportation. Three-layer and five-layer is used to produce corrugated boxes. Many products are packaged with three or five layers of corrugated cardboard, but the packaging is beautiful. Exquisite and colorful graphics and pictures are printed on the surface of corrugated boxes , which not only protects the goods inside, but also plays the role of publicity and beautification.
At present, many corrugated boxes made of three or five layers of corrugated cardboard have been placed directly on the sales counter and become sales packaging. Seven-layer or eleven-layer corrugated cardboard is mainly used to make packaging boxes for motors, flue-cured tobacco, furniture, motorcycles, and large household appliances. In some commodities, the inner box and outer box can be combined with corrugated cardboard, which is not only convenient for production, but also convenient for packaging, storage and transportation of commodities.
In recent years, according to the needs of environmental protection and the requirements of relevant national policies, commodity packaging made of corrugated cardboard has a trend of gradually replacing wooden box packaging.
