- An example of the use of multiple bags as a single unit is a large bag containing 2 to 20 kg of contents for packaging liquid foods such as sauces, ketchups, and uses.
- the multi-layer bag according to the present invention is particularly useful for storing and distributing large packages for business use in a frozen or refrigerated state. It is suitable because it has excellent pinhole resistance as a packaging.
- the bag-in-box uses an inner bag in which two or more films for storing liquids are stacked inside and heat-sealed in a bag shape, and the outer plastic is rigid enough to maintain its shape during transportation and storage. It is made of a container or a damper box, and the inner bag and outer package are combined to form a container.

- 27 and 27 are pinch rolls.
- the present invention is characterized in that a multi-layer bag is formed from a tubular film, and the tubular film is most preferably an inflation film as described above.
- the tubular film is most preferably an inflation film as described above.
- any cylindrical film can be adopted.
- a tubular shape can be obtained by welding both ends of two strip films.
- HD PE High density polyethylene
- MDPE Medium density polyethylene
- the resin constituting the innermost layer of the multi-layer bag is LDPE with excellent heat sealability, preferably tough and durable LLDPE (linear low-density polyethylene). More preferably, polyodor is suppressed and elution resistance is high.
- VLDPE linear ultra-low-density polyethylene
- L LDPE manufactured with a multi-site catalyst such as an Mg compound or Ti system has excellent film processability, but has a wide molecular weight distribution and therefore contains many components in the low molecular weight region, which is a polyodor.
- VLDPE produced with a single-site catalyst has a narrow molecular weight distribution and contains few components in the low molecular weight region, so that the transfer of polyodor can be suppressed.
- the multiple bag according to the present invention is preferably constituted by an unstretched film produced by an inflation method. That is, generally, in the case of a three-sided seal packaging bag having a back seal portion, four films overlap at the intersection of the back seal portion and the end face seal portion, and the boundary between the two adjacent films overlap. Therefore, pressure welding is not sufficiently performed, and a thin tunnel-shaped unsealed portion is easily generated.
- a laminated film including a rigid film such as biaxially stretched nylon to produce a double film the rigid stretched film hinders welding, and the back seal portion and the end face seal portion. At the crossing point of, eight films overlap, so that a thinner tunnel-shaped unsealed portion is likely to occur.
- the unstretched film of 60 ⁇ to 140 m manufactured by the inflation method of polyethylene (including LD, LLDPE, VLDPE, HDPE, MDPE, and including single layer and multilayer) is used. This makes it possible to suppress the occurrence of pinholes in the unsealed portion and to suppress the occurrence of pinholes during transportation and distribution by performing welding relatively softly and favorably.
- film sealing conditions are determined by setting the sealing temperature, pressurizing pressure, and sealing time.
- a condition such that the welded state is maintained even immediately after sealing after filling the contents. These conditions are more severe for heavy bags and hot filling. If sufficient sealing conditions are to be achieved correspondingly, the sealing portion is extremely crushed, that is, becomes thin, and an edge is generated at the boundary between the thin sealing portion and the film portion adjacent to the sealing portion. . This edge was found to cause pinholes.
- the tubular film is flattened and the two films facing each other are formed into an inner film and an outer film, and the back is formed by welding the both sides of the continuous edge of the inner film and the outer film.
- a multi-layer bag for bag making and filling comprising a horizontal sealing portion by forming a sticking seal portion and welding near both sides of an edge where the inner film and the outer film are not connected to each other.
- the seal portion is not extremely crushed and extremely thin, and thus no edge is generated at the boundary between the seal portion and the adjacent film portion.
- the rigidity of the film at the time of bag making and filling can be maintained, and it has become possible to greatly improve the sealing performance as compared with the conventional case.
- the tubular film used for multiple bags for bag making and filling is a cylindrical film having a polyolefin layer with a thickness of 10 to 70 m on both sides of a core layer with a thickness of 7 to 30 ⁇ . It is preferable to use a co-extruded blown film from the viewpoint of having both pinhole resistance, seal strength, seal stability, and impact bag breakage resistance.
- the core layer is a resin layer selected from unstretched PA, EVOH, and HDPE, it has excellent pinhole resistance and the melting point of the polyolefin layers (preferably linear low-density polyethylene layers) arranged on both sides. High, prevents film elongation at the time of sealing, and thus can improve sealing and pinhole resistance.
- the suitability of the packaging machine is improved.
- the blocking property between the inner surfaces of the bag filling bag can be prevented.
- a film for a bag using stretched PA as a base material is a film in which a heat-fusible film having a relatively low melting point such as linear low-density polyethylene is laminated on an inner layer, and the end of the film is used. It has been known that a heat-sealing method is used in which bag-making and filling are performed while repeating cutting and fusing. In addition, for the purpose of extending the storage period of the contents, a PA further laminated with a gas permeable film was sometimes used as a base material. (2-2) Relationship between pinhole and lamination>
- such a pinhole phenomenon has a problem that the rigidity of the laminated film is increased at a low temperature in applications where it is required to maintain the temperature at a low temperature during the distribution and storage processes, thereby increasing the pinhole phenomenon.
- the problem is particularly prominent, and the bag is required to be improved.
- This technology has a protective layer made of polyolefin resin, which has resistance to repeated bending and resistance to rubbing against corrugated cardboard.
- the protective layer also has a cushioning effect on sharp edges such as folds and corners. It is intended not to pierce an adjacent bag and break it.
- Stretched PA is widely used as a base material for bag-making and filling bags because of its excellent slipperiness and thickness uniformity.
- the problem of pinholes in heavy-duty or low-temperature distribution applications has been highlighted, and by providing a polyolefin protective layer on the outside as described above, although some improvement has been seen, the resistance of the base material itself has been improved. The pinhole property was not improved, and the effect was not yet reached until it was practically solved. (2-6) Attempt to use undrawn PA>
- stretched PA is frequently used as a base material for bag-making and filling bags, but undrawn PA is not suitable as a base material for bag-making and filling bags, from the viewpoint of general film selection factors.
- unstretched PA is inferior to stretched PA in slipperiness, and tends to cause uneven thickness, which hinders smooth supply of film. It was said that there was a problem that the mechanical suitability of the mounting device was poor.
- a sealing means when applying an unstretched PA film.
- Conventional filling bags use a two-layer laminated film in which a polyolefin seal layer is laminated on the inside of a base material made of a stretched PA film, and the inner surfaces of the facing films are welded together as shown in Figure 1.
- a bag-filling and simultaneous filling apparatus in which the back seal portion is formed by so-called "gassho bonding" is generally used. This is because, as shown in FIG. 2, in the so-called “envelope application” in which the inner surface of the other film is welded on the outer surface of one film, polyolefin is not welded to the PA and there is no sealing property.
- the tubular film is flattened and the two films facing each other are formed into an inner film and an outer film, and the back is formed by welding the both sides of the continuous edge of the inner film and the outer film.
- a multi-layer bag for bag making and filling comprising a horizontal sealing portion by forming a sticking seal portion and welding near both sides of an edge where the inner film and the outer film are not connected to each other.

- the tubular film used for multiple bags for bag making and filling has a wall thickness of 7 to 3
- a cylindrical co-extruded inflation film with a 10-70 ⁇ thick polyolefin layer on both sides of a 0 ⁇ core layer provides pinhole resistance, seal strength, seal stability, and impact crush resistance. It is preferable in terms of saying.
- the seal stability shown in the table is a good seal even if the seal temperature of the back seal and side seal slightly fluctuates (within 3 to the set temperature) during the running test.
- the thickness in parentheses in the layer configuration in Table 1 indicates the thickness [/ im].
- LL is a linear low-density polyethylene with a density of 0.922 and an Ml of 1.2, 0.0015 wt% of finely divided silica with an average particle size of 3.5 m as an antiblocking agent, and a lubricant as an lubricant.
- C-Ny is an undrawn polyamide.
- C4 is an ethylene- ⁇ -olefin (C4) copolymer having a density of 0.924 and an Ml of 1.0.
- EVOH is a saponified ethylene monoacetate copolymer with an ethylene content of 32 mo 1% and a saponification degree of 98%.
- AD indicates an adhesive polyolefin modified with maleic anhydride.
- F8 is a comparative example.
- LL (40) was dry-laminated on one side (inner layer serving as a sealing layer) of a film (15) biaxially stretched by post-processing a T-die molded unstretched polyamide film. It is a laminated film comprising:
- the back seal part of (1) is a normal continuous palm joint as shown in Fig. 1.
- the films of F1 to F7 make a pillow drive bag composed of envelopes as shown in Fig. 2.
- Bag dimensions 600 mm wide x 50 Omm long (external dimensions when empty bags are compressed)
- Seal width 20 mm (as shown in Fig. 2, the back-sealed seal part overlaps the outer film at one end with the lower surface of the inner film at the other end, along the center of the 30 mm wide overlap part.
- the width of the horizontal seal is 20 mm at the end of the film.
- Filling material fruit juice (filling temperature 65 ° C)
- the multiple bag according to the present invention, the method for producing the multiple bag, and the multiple bag for filling and filling the bag are different from each other in the process of producing the multiple bags, as in the case where a tubular film is flattened and two sheets are stacked. It is possible to supply multiple films in which both side edges parallel to the extrusion direction are continuous with each other, so it is possible to simplify the equipment by setting the multiple film supply system to one for each duplex. is there. In addition, it is useful because a high-quality multiple bag can be obtained without providing a means for preventing misalignment between multiple films in a film supply step, and a method for producing the same can be provided.
