PROBLEM TO BE SOLVED: To provide an inexpensive package containing a viscous material from which the material can be easily and thoroughly squeezed out with no remainder, and which can prevent the quality of the material from being deteriorated by the influence of the outside air. SOLUTION: This relates to a bag shaped package 1 packaging a viscous material formed by sealing the top, bottom, left and right sides 2, 3, 4, 5 of a pair of synthetic resin sheets. Roughly at the center of the sealed bottom side 3 of the package 1, a port 8 with a cap for communicating with the inside and the outside of the package 1 is inserted and sealed. Roughly from the center parts 6, 6 of the sealed right and left sides 4, 5 to the sealed bottom side 3 of the package 1, downward inclining seals 7, 7 are provided so as not to cross both ends of the port 8.
