A container bag comprising:

• an outer bag formed of a woven fabric made of a synthetic resin material and including a sidewall portion formed to have a quadrangular cross-section so that a hollow type accommodating portion is formed therein to store powder, a bottom portion connected to a lower end portion of the sidewall portion to cover a lower portion of the hollow type accommodating portion, a cover portion covering an upper portion of the hollow type accommodating portion and combined along a sewing line sewn to an upper end portion of the sidewall portion, an inlet combined with an opening formed at a central portion of the cover portion to guide an inflow of the powder, and a ring type transport belt sewn and connected to the sidewall portion;
• an inner liner inserted into the hollow type accommodating portion to seal the powder from the outside and accommodate the powder;
• and
• a plurality of connection loops formed in a loop form made of an elastic material and, to fix the inner liner to a relative position in an inner space of the hollow type accommodating portion, each having one end connected to an outer surface portion of the inner liner and the other end bent after passing through a through-gap in an interspace of the woven fabric forming the outer bag and doubly bent additionally by being inserted and withdrawn through a combining gap formed to be spaced from the through-gap so that the plurality of connection loops are fixed by being pressed and stretched together as the withdrawn end portion is stretched.
