Problems solved by technology

At this time, if the left and right ends of the folded part that are thicker than other parts are thermally welded with a weather strip, the weather strip will float at other parts than the left and right ends of the folded part, and the wings (flaps) The side parts are not well welded, resulting in a problem of poor sealing

Embodiment approach

[0046] Hereinafter, modes for implementing the present invention (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings. In the overall description of the embodiment, the same reference numerals are attached to the same elements.

[0047] (packaging bags for microwave oven 10)

[0048] First, based on Figure 1 to Figure 4 The packaging bag 10 for a microwave oven according to the embodiment will be described.

[0049] Such as figure 1 As shown, the packaging bag 10 for microwave ovens is a bag-shaped packaging body formed of two films. The two films are composed of a rectangular first film 11 on the front side and a rectangular second film 12 on the back side.

[0050] Such as figure 2 As shown, the packaging bag 10 for a microwave oven includes: an end sealing portion 13, which becomes the bottom when the content is filled; an opening 15, which is not thermally welded to the upper side when the content is filled; It is for...

Abstract

Provided are a bag-making device and a bag-making method capable of improving the productivity of microwave oven packaging bags. The bag-making device (10) is equipped with: a sheet-cutting and -dividing unit (37) for cutting and dividing a film sheet (31) in the width direction; a first conversion roller (51) and a second conversion roller (52) for respectively converting a first film sheet (41) and a second film sheet (42) from a second orientation in which the width direction is perpendicular to the horizontal direction to a first orientation in which the width direction is horizontal; and a folding unit (53) for forming a pair of flaps, which extend in the running direction, in the first film sheet (41) that has been converted to the first orientation. The first conversion roller (51) extends diagonally upward toward the front of the running direction and the second conversion roller (52) extends diagonally downward toward the front of the running direction, and so that the center position in the width direction of the first film sheet (41) converted to the first orientation matches with the center position in the width direction of the second film sheet (42) converted to the first orientation.

Description

technical field [0001] The invention relates to a bag making device and a bag making method. Background technique [0002] A bag-shaped packaging bag formed by bonding two films is widely used now. [0003] Conventionally, in such a packaging bag, a flap (flap) is formed on one of the two films, and a steam release seal is provided on the flap (for example, see Patent Document 1). [0004] Patent Document 1 discloses a package in which a composite film having at least one surface made of a sealing layer is used, and the sealing surface is used as an upper lower member and a sealing layer having wing portions formed at least on the sides is stacked as a lower upper member, and the peripheral portion is sealed. bag. In this packaging bag, a point seal portion connected to the folded portion of the wing portion is formed as a central area in the wing portion, and one or more vapor-through members are added to the point seal portion. [0005] According to the packaging bag of...
