The bag for bag-in-box of this invention comprises: a bag body composed of flat portions and side portions each having a folding line along which the side portion is folded inward; oblique seal portions provided at respective corner portions of the bag body, the oblique seal portion being formed by obliquely cutting-off the respective corner portions; and a triangular fin portion integrally formed with the oblique seal portion; wherein the flat portion and the side portion are composed of several sheets of synthetic resin films that are superposed to each other. The dimensions of the bag shall be set within a predetermined range so as to meet the International Standard of a pallet. The opening portion to be formed on the outer box of the bag-in-box has a size enabling to sufficiently draw out a spout and the bag body portion around the spout to form a funnel-shape. According to the present invention, there can be provided an inner bag for a bag-in-box excellent in shock resistance, content discharging property and self-supporting property at a time when the inner bag is filled with the content.

A pouch for containing therein a content including front and rear pouch bodies formed of a laminated film, and heat-sealed portions at confronting side edge portions of the front and rear pouch bodies for providing a fluid tight structure of the pouch. The pouch is characterized in that: the laminate film includes uniaxial oriented plastic film layer provided with molecular orientation in one direction, and at least two notches are formed at positions close to each other at least one of the heat-sealed portions for defining a leading end portion of a tearing zone. The notches are directed in a tearing direction parallel with a direction of the molecular orientation of the laminated film.

A beverage container configured from a front and a rear surface portion, a base portion, and a pair of gusset portions. The gusset portions configure side portions of the container by being sealed to mutually confronting edge portions of the front and rear surface portions and the base portion. The upper portions of the front and rear surface portions configure a neck portion that has a more slender shape than the remainder of the front and rear surface portions and that extends in a single direction. A notch is formed in the edge sealed portion of the neck portion. The front and rear surface portions are sealed directly together at a predetermined region corresponding to the notch without the gusset portions existing therebetween. A straw extends from and is positioned within the neck portion. The neck portion can be opened from the notch.

A multilayer sheet harmless to human beings, having a certain gas-barrier property, and comprising an easily-produced metal film layer and a packaging material made of the multilayer sheet. The multilayer sheet is composed of at least a resin film layer and a metal film layer of magnesium or a magnesium alloy integrally formed on the resin film layer by evaporation, electron beam, or sputtering. Magnesium is harmless to human beings, and therefore such a multilayer sheet can be preferably used as a material of a food or medicine bag.

A fastener bag includes a packaging bag formed by heat-sealing side parts of a packaging sheet in a butt seam, and a fastening device attached to the inner surface of the packaging bag. The fastening device includes a male fastening member and a female fastening member. The male fastening member is disposed on one side of the heat-sealed butt seam of the packaging bag, and the female fastening member is disposed on the other side of the heat-sealed butt seam of the packaging bag so as to be engage with the male fastening member, and a tear-facilitating means is interposed between the male and the female fastening member. The fastener bag is capable of being opened and of being reclosed, and is suitable for use on an automatic filling and packaging machine.

A reclosable packaging bag comprises a main bag body having an opening portion and at least one heat-sealed portion; and a linear fastener provided on the opening portion of the main bag body. The linear fastener is provided along the opening portion of the main bag body by an insert injection molding so as not to extend to the heat-sealed portions. A method for manufacturing the bag comprises the three steps. First, the first and second linear fastening members are formed on a prescribed position of a sheet of film material by an insert injection molding so as to be spaced from each other. These fastening members are engageable with each other to form a linear fastener. Second, the sheet of film material is folded in two so that the fastening members can engage with each other. Third, each of opposite portions of the sheet of film material thus folded is heat-sealed to form side heat-sealed portions.

A gusset bag for packing a content comprises a bag body having a tubular structure and composed of a pair of opposing flat portions constituting front and back surface portions and two side surface portions connecting the front and back surface portions at both side edges thereof and having lines folded inward which extend along longitudinal direction of the side surface portions and along which the side surface portions are folded inward. A zipper element is mounted on inner surfaces of the flat portions at portions near the end opening of the bag body. A fused seal portion formed to and near the end opening portion of the bag body to seal the end opening portion, the fused seal portion including an end seal portion extending along an entire length of the end opening and side seal portions extending from both ends of the end seal portion along the side edges of the flat portions. The side seal portions extend beyond the portions on which the zipper element is mounted. The sealing process is carried out integrally with portions of the side surface portions, which are once inwardly folded along the folding lines and then drawn out and folded outward from the end opening of the bag body. The zipper element is mounted to the portions near the end opening between the end opening and the once folded and then drawn out side surface portions.

There is provided a fastener bag capable of improving working efficiency for the filling of inner content and surely forming a bag cut-starting portion. The faster bag 1 is formed as gusset-type packaging bag, to which a fastener 10 for freely opening or closing the packaging bag is attached. The fastener 10 is composed of a male portion 11 to which a projected thread 11b is formed and a female portion 12 to which a groove 12b is formed so as to be engaged with the projected thread 11b. Base portions 11a and 12a of both the portions 11 and 12 are attached to an inner surface of one of the flat surface portions 2 or side surface portions 3 so that the projected thread 11b and the groove 12b face each other. A cut-tape 14 for separating the flat surface portion 2 into the male portion side and the female portion side is provided between the base portions 11a and 12a.
