Description

Technical Field

[0001] This utility model relates to the field of cremation coffin technology, specifically a padded corrugated paper cremation coffin. Background Technology

[0002] In the traditional funeral industry, wood has always been the main material for making cremation coffins. However, the use of large amounts of wood has caused great depletion of forest resources, which runs counter to the current concept of sustainable development. At the same time, as people’s environmental awareness gradually increases, higher requirements are also being placed on the environmental performance of funeral products. Traditional cremation coffins may produce more pollutants during the burning process, which aggravates the environmental burden.

[0003] Corrugated paper, as a common and recyclable material, is widely available and inexpensive. It also has advantages such as being environmentally friendly, easy to burn, and having low emissions, which perfectly fits the current trend of green funerals. However, if the coffin is made entirely of corrugated paper, its load-bearing capacity will be much lower than that of a traditional all-wooden coffin. In addition, traditional wooden coffins are unstable in terms of the placement and fixation of the deceased, leading to many trivial matters. Therefore, we have proposed a padded corrugated paper cremation coffin. Utility Model Content
