Abstract: Provided is a gas barrier laminated film having no fear of deterioration in transparency and excellent in transparency and gas barrier property at a high humidity as well as a process for producing same. The present invention is featured by a gas barrier laminated film wherein a gas barrier layer (B) has been formed on at least one surface of a film substrate (A), the gas barrier layer (B) being comprised of a composition (b3) of an ethylene-vinyl alcohol copolymer (b1) having an ethylene content of 1˜19 mol % and (meth)acrylic acid polymer (b2). In case the film substrate is coated on at least one surface thereof with a vapor deposition layer of an inorganic oxide or the OPP film is coated on at least one surface thereof with the layer of the modified propylene polymer, the gas barrier laminated film is obtained which is more enhanced in adhesion power to the film substrate.

Abstract: Disclosed is a composition provided with biodegradable property and transparency which is excellent in heat sealing property at low temperatures, peelability and adhesiveness to substrate as well as a film or laminate of the composition. The composition comprises as indispensable components thereof 27-70% by weight of polylactic acid, 70-27% by weight of an aliphatic polyester, and 1-20% by weight of a tackifier selected from the group consisting of: an aliphatic cyclic hydrocarbon resin, a metal salt of a rosin ester, and a rosin ester having an acid number of 10 or less.

Abstract: A wood decorative material coated with resin composite film, comprising a laminate of, arranged in the following order, a wood substrate; a heat bonding layer (A) formed from a heat bonding resin composition comprising 100 parts by weight of a thermoplastic resin (a-1) and 0.001 to 80 parts by weight of a tackifier resin (a-2), the above heat bonding resin composition having a melting point or softening temperature of 170° C. or below and exhibiting a melt flow rate (MFR) at 190° C. of 1 to 500 g/10 min; and a mar-proof surface layer (B). Not only can beautiful appearance be obtained while retaining natural texture without the application of lacquer but also surface protection and bending working properties are improved.

Abstract: A drawing system in which a thickness and degree of orientation of an oriented film or the like is maintained in a uniform manner under a condition of a high speed, shortened is a time required from a time when a molding material is charged in an extruder and drawing started until a time when a film is taken up on a take-up apparatus, and a high quality film or the like is produced at a high speed and besides, a probability for a not-oriented or oriented film or the like to be broken down during drawing is reduced. A thickness and degree of orientation of a film are independently measured in thickness gauges and a film orientation measuring apparatus in a continuous manner after longitudinal drawing or lateral drawing and measured values are input to a computer.
