摘要： A method of manufacturing a packaging sheet, the method being capable of not only greatly improving a heat insulation property of the packaging sheet, but also minimizing the volume of cells of the packaging sheet without opening the cells by cutting or needle-punching the cells, thereby facilitating storage and transportation of the packaging sheets while significantly reducing logistics costs.

摘要： Provided is a method for producing a packing sheet with improved insulation and storage properties, the method including: producing a cell packing sheet by attaching together two overlapping films such that multiple cells are formed therebetween, by sealing second ends of the cells, and by disposing a check valve in an injection hole formed in a first end of each of the cells; inflating the cells by injecting a fluid through the respective check valves of the cells; attaching upper and lower films respectively to upper and lower sides of the cell packing sheet; cutting the cell packing sheet along a second edge thereof together with the upper and lower films such that the second ends of the sealed cells are opened; and sealing a second end of the upper film, a second end of the cell packing sheet, and a second end of the lower film.
