PROBLEM TO BE SOLVED: To solve the problem that an aluminum foil laminated film is split and a liquid and air are leaked from a split portion when being punctured with the needle of a water server since a conventional liquid packing bag supplying a hydrogen-containing beverage liquid to the water server has an outer layer made of the aluminum foil laminated film and an inner layer made of a film.SOLUTION: A liquid packing bag is set in a water server, is inserted with a hollow needle. A hydrogen-containing beverage liquid is flown down from the needle by gravity. The breakage of a punctured portion by the needle is prevented by making an outer layer due to the vacuum packing of a uniaxially stretched multilayer film or a uniaxially stretched monolayer film after an inner bag consisting of a metal foil laminated film and being an inner layer is fully filled with the hydrogen-containing beverage liquid to the mouth of the inner bag and sealed. |
