Abstract: A packaging bag includes a first face including a first edge disposed on a first side of an opening; a second face facing the first face and including a second edge disposed on a second side of the opening; and a cushion in an expandable sheet form and being suspended between the first edge and the second edge, and in which a plurality of slits extending in a direction intersecting a suspension direction are provided in a staggered manner, wherein a percentage of a basis weight of a sheet material forming the cushion with respect to a basis weight of a sheet material forming the first face and the second face is 55 to 80%.

Abstract: The present invention provides a method for easily and efficiently manufacturing microfibrous cellulose composite sheets. The present invention is a method for manufacturing microfibrous cellulose composite sheets, including a preparation process in which a polymer emulsion is mixed with an aqueous suspension including microfibrous cellulose, thereby preparing a mixed fluid, a papermaking process in which the mixed fluid is dehydrated on a porous base material through filtration, and a sheet including moisture is formed, and a drying process in which the sheet including moisture is heated and dried. In addition, the present invention is a method for manufacturing a microfibrous cellulose composite sheet laminate, in which the microfibrous cellulose sheets are thermally compressed and thus laminated as they are or after being provided with a polymer layer on at least one surface thereof.
