Abstract: A manufacturing method of a package bag (10) according to the present invention includes: a cured portion forming step of forming a cured portion (15a, 15b) on at least one side of a forming position of a rib (14) by crystallizing at least a portion of a resin constituting a film (11) by heating and cooling the film (11); and a rib forming step of forming a rib (14) by pressing the film (11) using concave and convex molds. According to the present invention, it is possible to maintain an opening state of a spout (12). Further, since additional material is not required, it is possible to suppress increase in the thickness of the package bag (10) and to reduce the bulkiness of the package bags.

Abstract: A laminate production method using a surface-modified film includes the step of laminating a first substrate and a second substrate on each other, where the first and second substrates have thermoplastic resin films or cellophane films and are different in type from each other. One of the first and second substrates has a surface with a heat-bonding-modified layer formed by surface modification using an atmospheric plasma treatment apparatus. The other of the first and second substrates has an air corona-treated surface. The first and second substrates are individually fed from respective rolls of film, which are obtained by respectively winding the first substrate and the second substrate. The surface having the heat-bonding-modified layer faces the air corona-treated surface, and the first and second substrates are thermocompression-bonded together using a heated roller without applying an adhesive or anchoring agent to perform a continuous lamination.

Abstract: A substrate which is either a first substrate or a second substrate consisting of a different kind of thermoplastic resin film or cellophane film, and which is drawn out from rolled films where the first substrate and the second substrate are rolled respectively. The substrate has a surface of the hot gluing reforming layer which was formed with the surface modification with an atmospheric pressure plasma processor, and the other substrate has a surface with which an air corona processor is possessed. And the substrate and the other base member are opposed, and are attached together with a heating roll with spreading neither an adhesive nor an anchor agent.

Abstract: Disclosed is a method for determination of a smoking trend in a subject which is useful for the assistance or therapy for smoking cessation, which comprises the steps of detecting one or more polymorphisms occurring on one or more genes selected from the genes (1) to (3) or a genome or in the neighborhood of the genes or the genome and determining the smoking trend based on the results of the detection: (1) nicotinic acetylcholine receptor ?2 subunit (CHRNB2) gene; (2) serotonin transporter (SLC6A4(5HTT)) gene; and (3) nicotinic acetylcholine receptor ?4 subunit (CHRNA4) gene.

Abstract: Provided are a polyester resin for use in a toner binder which is excellent in terms of offset resistance and low-temperature fixability, which keeps triboelectric charge stability even in an environment of a high temperature and a high humidity, which has excellent durability, and which is used in a toner that gives vivid image characteristics, a process for producing the same, and a toner using the same. The polyester resin for use in the toner binder is formed by linking at least a part of the crosslinked low-molecular polyesters through a dicarboxylic acid used as a linking agent.
