Corrugated paper, especially corrugated cardboard, has had a profound impact on packaging, logistics, environmental protection, education, and anti-counterfeiting.
Corrugated cardboard possesses high mechanical strength, resisting collisions and drops during handling, providing protective packaging for goods. By the early 20th century, corrugated cardboard had become widely adopted and applied, becoming one of the primary materials for packaging containers.
Corrugated cardboard is a recyclable and environmentally friendly material made from naturally degradable wood fibers, and it can also be reused. The reusability and recycling of corrugated cardboard reduces environmental pollution.
Colored corrugated paper is also frequently used in handicrafts.
Watermarked paper, also known as decorative paper or embossed paper, has had its manufacturing process used since the Song Dynasty for anti-counterfeiting measures in paper money (such as Jiaozi). The process of making watermarked paper was used as one of the anti-counterfeiting measures for paper money, and its principle evolved into modern watermarking technology. Watermarks are widely used in printing high-grade official documents, banknotes, passports, certificates, ledgers, etc., requiring anti-counterfeiting features.
Corrugated cardboard is used in creative sculpture design and stylish home furnishings such as creative corrugated cardboard chairs.
