A gusset bag (10) is formed of a pair of flat surface parts (12A and 12B) facing each other, and side gusset parts (14) folded to the inside of the bag. The gusset bag (10) has side heat-sealing portions (16A) at which the sides of the flat surface part (12A) and sides of the side gusset parts (14) are joined at the inner surfaces thereof, side heat-sealing portions (16B) at which the sides of the flat surface part (12B) and the other sides of the side gusset parts (14) are joined at the inner surfaces thereof, and closing sealing portions (18) at which the side heat-sealing portions (16A) and the side heat-sealing portions (16B) are joined at the outer surfaces of the side gusset parts (14) by ultrasonic sealing. With this configuration, in the gusset bag (10), it is possible to easily close the gusset parts, while preventing film pieces or dust from entering the bag in a step of closing the gusset parts.

In the pouch manufacturing method, a branched part (254) is formed by folding back at least one side part of a web-form body member (240) at a fold-back line running along the feeding direction of this body member. The body member (240) is guided by a guide so that the pass line length of a portion occupying an arbitrary position is substantially constant from the initiation of fold-back to the completion of fold-back; accordingly, a natural and favorable fold-back can be achieved without generating any slack or wrinkles in the web, so that pouches such as pouches having a branched part (254) can be manufactured with a favorable appearance and commercial properties.

A packaging bag and a method of manufacturing the packaging bag, the packaging bag formed by heat-sealing plastic films and having an outflow port (3) formed of a heat seal part (2) and a non-heat seal part (6), wherein the inner surfaces of the films forming the non-heat seal part (6) side of a boundary part (Y) between the heat seal part (2) and the non-heat seal part (6) of an outflow port passage (4) come into contact with each other without providing a clearance in closed state, whereby contents can be prevented from oozing out of the outflow port (3); the method comprising the steps of transferring a valve material (103) limiting the movement of filled material after a bag is formed according to the transfer of web-like body materials (101, 102) forming the packaging bag, and heat-fusing the body materials (101, 102) to the valve material (103) in the state of a seal obstructing member (106) provided on the passing side of the filled material, whereby the packaging bag having a valve function such as a reverse flow prevention function can be continuously manufactured.
摘要:
In the pouch of the present invention in which a pouring spout (3) is formed by means of a heat-sealed part (2) and a non-heat-sealed part (6) by heat sealing plastic films, the inside surfaces of the films that form the portion of the boundary area (Y) between the heat-sealed part (2) and non-heat-sealed part (6) of the pouring spout passage (4) on the side of the non-heat-sealed part (6) contact each other so that no gaps are left in a closed state. Accordingly, even if the pouch is suspended with the pouring spout (3) down following the opening of the pouring spout (3), the leakage of the contents such as a liquid or the like accommodated in the interior of the pouch from the pouring spout (3) a small amount at a time can be securely prevented. The gap-free contact of the inside surfaces of the films can be accomplished by uniformly pressing the films in the boundary area (Y). Furthermore, in the pouch manufacturing method of the present invention, a valve member (103) which restricts the movement of the contents when the pouch is formed is conveyed in accordance with the conveying of web-form body members (101, 102) that form the pouch, and this valve member (103) is welded to the body members (101, 102) in a state in which a sealing preventing member (106) is interposed on the side on which the contents pass through; accordingly, pouches that have a valve function such as a reverse flow preventing function or the like can be continuously manufactured. In addition, in this pouch manufacturing method, in cases where a branched part (254) if formed by folding back at least one side part of a web-form body member (240) at a fold-back line running along the feeding direction of this body member, the body member (240) is guided by a guide so that the pass line length of a portion occupying an arbitrary position is substantially constant from the initiation of fold-back to the completion of fold-back; accordingly, a natural and favorable fold-back can be achieved without generating any slack or wrinkles in the web, so that pouches such as pouches having a branched part (254) can be manufactured with a favorable appearance and commercial properties.
摘要:
The invention relates to a material designed for production of packaging which has the form of a continuous band joined by welding with overlapping mesh elements, wherein this continuous band (1) is made of paper coated with polyolefin on at least one side. The polyolefin coating allows joining the paper with the mesh (2) by means of the welding method. The invention also relates to the method of producing the packaging material in the form of a continuous band containing mesh elements consists in coating of at least one side of continuous paper band with polyolefin, then placing the mesh on the coated side of paper in such a manner that the part of it is superimposed on the paper and forms an overlap, and finally this part is subjected to welding at the temperature within the range of 180 - 300°C.
