Abstract: An object of the present invention is to provide a film and a pouch having basic characteristics such as a strength and barrier properties and achieving good openability. A film (10) according to the present invention includes at least a sealant layer (11), the film is formed with a cut guide line (G), and the cut guide line includes an impression (11A) formed in a surface of the sealant layer. In a pouch (30), the films are superimposed in a state where the sealant layers face each other, and peripheral edge parts are heat-sealed. The cut guide line is placed extending across at least a position where heat seal is not performed.

Abstract: 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.

Abstract: A packaging bag including a polyester-based multilayer film. The multilayer film includes at least: an innermost layer formed of a biaxially stretched polyethylene terephthalate film; a layer formed of polybutylene terephthalate; and/or a layer formed of a blend of polyethylene terephthalate and polybutylene terephthalate. The biaxially stretched polyethylene terephthalate film has a heat sealing portion that is amorphized or low-crystallized by laser light irradiation. The packaging bag is formed by allowing the innermost layers of the polyester-based multilayer film to be opposed to and superimposed on each other, and heat sealing the heat sealing portions.

Abstract: The suction device includes a suction port revolving around a revolution axis while sucking a fluid so as to generate an artificial tornado. The suction port revolves around the revolution axis while sucking the fluid, so that it is possible to generate an artificial tornado more stably.
