For example, a handle may be formed in a collective wrapping bag such as caramel wrapping or shrink wrapping as a member (or retrofitted) separately from the collective wrapping body.

Further, the handle 37 is formed at the center 31A of the upper surface 31 of the collective packaging bag 30. The position where the handle 37 is provided is not limited to the upper surface 31 of the collective packaging bag 30, and may be a surface other than the upper surface 31 (lower surface 32, front 33, back 34, side 35, side 36). In this case, the surface other than the upper surface 31 of the collective packaging bag 30 is the upper portion of the collective packaging bag 30.

The handle 37 has four folded resin films stacked at both ends (ends 37B and 37C) of the handle 37 in the longitudinal direction (X direction), and two in the vicinity of the central portion 37D of the handle 37. It is stacked and sealed. The mode of this seal is not limited to heat fusion (heat seal), and the seal may be formed by applying an adhesive, an adhesive, or the like.

(Not shown) may be provided.

A finger hook (not shown) may be further formed on the handle 37. The form of the finger hook is not particularly limited, but can be configured by, for example, a notch such as a slit. Further, this notch can be formed by an intermittent slit such as a perforation, and a finger hook may be formed by breaking the perforation. The shape of the notch is not limited, and may be a straight line, a curved line, a wavy line, a circular shape, an elliptical shape, a quadrangular shape, or a shape similar thereto.

Further, the number of finger hooks is not limited, and one or two or more notches can be formed. When forming two or more notches, the handles 37 may be arranged at predetermined intervals in the longitudinal direction (X direction).

Further, the handle 37 may be provided with a reinforcing film (not shown). This reinforcing film can be formed of a resin film. The material of the reinforcing film is not particularly limited, and may be the same as or different from the material of the resin film constituting the handle 37. Examples of such a resin film include a laminate of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and PE-ethylene vinyl alcohol copolymer (EVOH) -PE (PE / EVOH / PE). , Polyvinyl chloride (PVDC) and other resin films can be used. By providing such a reinforcing film, the handle 37 on which the finger hook is formed (for example, the central portion 37D of the handle 37) can be reinforced.

Further, the thickness dimension of the reinforcing film is arbitrary. For example, the thickness of the reinforcing film can be 20 μm or more, preferably 30 μm to 150 μm, and more preferably 50 μm to 130 μm. By setting the thickness dimension of the reinforcing film within such a range, it is possible to prevent the handle 37 from being stretched or broken. Further, the reinforcing film can be adhered to the handle 37 at the time of forming the seal by the above-mentioned heat welding or the like.
