1、 Materials and Structure Material: Paper coffins are mainly made of multi-layer corrugated paper, honeycomb paper, or recycled paper, which are not only renewable but also have high strength and durability. Structure: Paper coffins are usually composed of a coffin body and a coffin lid, connected by mortise and tenon joints and designed with protruding stops to ensure overall lightweight and good sealing. The coffin body presents a trapezoidal design with a high end wide and a low end narrow. The top surface of the coffin lid is a convex circular arc, and there are concave conical cavities on the outer sides of both ends to enhance sealing. Internally, the stability of transportation is improved by suppressing the body fixing groove. 2、 Production process Glue bonding process: The main body of a paper coffin is usually made of multiple layers of corrugated cardboard glued together, and the bottom structure may include a sandwich layer to increase strength. Surface treatment: The exterior of the paper coffin may be covered with high-end fabrics and decorated with gold "Dian" characters to enhance its beauty and solemnity. 3、 Usage and maintenance Load bearing capacity: High quality paper coffins can bear up to 150kg, which can meet the needs of body transportation and cremation. Packaging and transportation: Paper coffins should be protected from rain, direct sunlight, moisture, and pollution during transportation. Transparent plastic packaging bags are usually used for packaging. Maintenance and upkeep: Although paper coffins have good durability, attention should still be paid to avoiding sharp objects scratching or heavy objects squeezing them during use. 4、 Market and Application Market demand: With the increasing attention to environmental protection and sustainable development, the market demand for paper coffins is also gradually growing. Especially in the context of an aging society, paper coffins are becoming increasingly popular as a lightweight and environmentally friendly funeral item.
