(57) [Summary] [Purpose] A mixture of packaging sheets for meat and a package can be easily applied uniformly, and the ends can be laminated and heat-sealed easily, resulting in high sealing strength and high Allow filling meat products with filling pressure. [Composition] Copolyester composite 60% and N ・ BKP4 0% was put into a beater to prepare an aqueous slurry for papermaking. This slurry was made into paper with a basis weight of 40 g / m 2 . Next, dissolved pullulan, millet pigment, etc. were printed on a long continuous sheet. The long continuous sheet was wound around a cylindrical mold and overlapped to form an envelope, and both ends were heat-sealed with a heat sealer. This cylindrical packaging sheet was heat-sealed with a heat sealer reaching the full width in the direction orthogonal to the longitudinal direction, and the fused portion was cut to form a bag-shaped casing. |
