摘要： An object of the present invention is to provide a pouch and a liquid-containing pouch having high resistance to falling breakage. A pouch (10) is a pouch formed into a bag by an outer peripheral sealing part (20). The pouch includes an accommodating part (30). A fragrance component emission part (40) is formed in the film on at least one side at a position corresponding to the accommodating part. The fragrance component emission part is composed of a material removal part (41) or a score having a notch form, in a range of part of the film in the thickness direction thereof. The tensile strength of the film in a fragrance component emission area in the width direction of the pouch is at least 90 N/50 mm, and the tensile strength thereof in the height direction of the pouch is at least 125 N/50 mm.

摘要： Provided is a microwavable pouch having a rectangular outer shape in plan view. The microwavable punch includes an automatic steam release mechanism. The automatic steam release mechanism includes a steam release portion and a steam release seal portion surrounding the steam release portion, and assuming that there is an inscribed ellipse in contact with centers of inner edges of sides of a peripheral seal portion of the pouch, the steam release seal portion is formed so that a circumference of the inscribed ellipse is positioned in a width region of a seal separation start portion of the steam release seal portion closest to a center point of an accommodation portion or in a vicinity of the seal separation start portion.

摘要： Provided is a spouted pouch capable of improving the ability to suspend pouring liquid contents, the ease of adjusting a pouring force, and the ease of repouring. In the spouted pouch (10), a pouch body (20) has flow path control seal portions (22) formed on both left and right sides across an imaginary line A inside the outer edge seal portion (21). Assuming that a thickness dimension of the spout attachment base portion (31a) is taken as X, length dimension from the spout attachment base portion (31a) to the action point portion (22a) of flow path control seal portions (22) is taken as L, and a width dimension between the action point portions (22a) is taken as W, the thickness dimension X, the length dimension L, and the width dimension W are set so as to satisfy relationships of W/X=1.2 to 2.0 and L/X=0.3 to 1.5.

摘要： It is an object of the present invention to provide a pouch capable of releasing the fragrance component contained in the content to the outside without opening the pouch while avoiding leakage to the outside and deterioration in quality of the content with a simple configuration, and a liquid content-containing pouch. The pouch of the present invention is a pouch that is formed in a bag shape by forming an outer peripheral sealing part by thermally bonding a film, and accommodates a content in an accommodating part inward from the outer peripheral sealing part, wherein a fragrance component releasing part is formed at a position corresponding to the accommodating part on at least one side of the film, and the fragrance component releasing part is configured of at least one of a material-removed part and a notched score formed in a partial range in a thickness direction of the film.

摘要： Provided is a microwavable pouch including an automatic steam venting mechanism, which includes a steam venting sealing portion, a slit, and a flap piece. The steam venting sealing portion includes a seal peeling start portion. The slit includes a pair of slit end portions and a slit intermediate portion formed toward a region closer to the seal peeling start portion than the pair of slit end portions, and the automatic steam venting mechanism further includes an unsealed portion formed to cover the entire periphery of the slit and a control sealing portion formed by heat-welding a part of the flap piece to a second film.

摘要： To provide a microwave pouch that favorably prevents both of hole formation of the pouch and spurting of contents, with a simple structure. A microwave pouch (10) includes a self-venting mechanism (20). The self-venting mechanism (20) has an annular venting seal (30), a steam release part (40) surrounded by the venting seal (30), and a movable piece (60) defined by a slit (50) formed in the steam release part (40). The venting seal (30) has a seal peel initiation part (31) where peeling is started by steam generated inside the pouch (10) during heating. The slit (50) includes slit both ends (51), and a slit intermediate part (52) formed to extend from the slit both ends (51) toward a region away from the seal peel initiation part (31) and connecting the slit both ends.

摘要： The present invention addresses an object for providing a microwavable pouch in which a slitting portion does not unintentionally rupture during heating while obtaining excellent openability. A microwavable pouch according to the present invention is formed into a bag shape by thermally bonding laminated films and includes an automatic steam venting mechanism. The laminated film has a configuration of polybutylene terephthalate layer/vapor-deposited polyethylene terephthalate layer/cast polypropylene layer, or a configuration of vapor-deposited polyethylene terephthalate layer/polybutylene terephthalate layer/cast polypropylene layer, and at least part of the intermediate layer of the laminated film has a slitting portion.

摘要： A packaging bag composed of a multilayer film and having a steam releasing mechanism. The multilayer film has at least a base layer and a welding layer and has a moisture content of not more than 1.0% in a state in which the packaging bag is filled with a content. The steam releasing mechanism has at least a steam releasing portion formed to have a maximal width of 3 to 20 mm. The internal pressure of the packaging bag is kept to be not more than 115 kPa during a period from the time the internal pressure is released through the steam releasing portion as a result of an increase in the internal pressure caused by heating in a microwave oven to the time the heating in the microwave oven finishes.
