The invention and application of corrugated paper has a history of 100 years. It has the advantages of low cost, light weight, easy processing, high strength, good 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.
Use of corrugated paper
Corrugated board began at the end of 18, and its application increased significantly at the beginning of 19 because of its light weight, low price, wide use, simple manufacture and recycling. By the beginning of the 20th century, it had been widely promoted, popularized and applied to the packaging of various commodities.
Type A corrugated paper and type B corrugated paper are generally used for transport outer packing boxes, and type B corrugated paper is generally used for beer boxes. E-cold is mostly used as a single packaging box, which has certain aesthetic requirements and moderate content weight. F-shaped corrugations and G-shaped corrugations, collectively referred to as microwave corrugations, are extremely thin corrugations, which are used as disposable packaging containers for foods such as hamburgers and cream cakes, or as packaging for microelectronic products such as digital cameras, portable stereos and refrigerated goods.
