Abstract:
A multilayer produce packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.

A decorative resin composition containing a metal pigment having an average thickness of not more than 600 nm dispersed in a blend of a low-density polyethylene (LDPE) having a density of not less than 0.910 g/cm 3 but less than 0.930 g/cm 3 and a linear low-density polyethylene (LLDPE) having a density of 0.910 to 0.925 g/cm 3 .
Abstract:
Provided is a synthetic resin container (1) that is formed in a bottle shape having a mouth (2) and a trunk (4) and that is provided in the trunk (4) with at least one reduced pressure absorbing panel (6). The trunk (4) has a density of 1.3695 g/cm 3 or more, and a ratio of a crystal orientation in a transverse direction with respect to a total value of a crystal orientation in a machine direction and the crystal orientation in the transverse direction in the trunk (4) is less than 44%.
Abstract:
The present invention relates to a directly blow-formed container including at least an outer layer composed of a propylene polymer. The outer surface of the layer composed of a propylene polymer composition containing at least a propylene polymer selected from an ethylene-propylene random copolymer and a homo polypropylene, and also a nucleating agent based on nonitol or sorbitol, is flame-treated to have a high surface gloss and an excellent appearance since occurrence of air-trapping and sharkskin is prevented or reduced.
Abstract:
A thermoplastic resin film of the present invention contains at least a base layer containing a thermoplastic resin and a heat seal layer containing a thermoplastic resin; a melting point of the thermoplastic resin contained in the heat seal layer is lower than a melting point of the thermoplastic resin of the base layer; a core roughness depth Rk of a surface of the heat seal layer being from 1.2 to 9.0 µm; and a ratio Rzjis/Rk of a ten point height of roughness profile Rzjis to a core roughness depth Rk of the surface of the heat seal layer measured in accordance with JIS B0601:2013 Appendix 1 being from 2.0 to 9.0.
Abstract:
The present invention relates to a process for production of polyethylene terephthalate comprising the steps of, providing a terephthalic acid monomer, providing ethylene glycol; providing a titanium based catalyst; esterification of a mixture of the monomer, ethylene glycol and titanium based catalyst in at least two steps, wherein the esterification temperature is in a range of 250°C to 280°C and increased, within the range, in each subsequent step; polymerisation at a temperature in a range of 260°C to 290°C in at least two steps and is increased or kept constant, within the range, in each subsequent step to obtain the polyethylene terephthalate.
Abstract:
Provided is a preform (1) to be biaxially stretch blow molded into a container (11) by using a liquid as a pressurizing medium. The preform (1) is formed in a bottomed tubular shape including a mouth (4), a trunk (3), and a bottom (2) by extrusion blow molding. The preform (1) includes bottom parting lines (2a∼2d), which are formed in the bottom (2) due to the extrusion blow molding, and the bottom parting lines (2a∼2d) are configured to extend to the outer side from the axis of the bottom (2) to divide the bottom (2) into at least three parts in the circumferential direction. Also provided is a container (11) that is formed by biaxially stretch blow molding the preform (1) by using the liquid as the pressurizing medium.
Abstract:
A coated metal sheet further covered with an organic resin obtained by forming, on at least one surface of a metal sheet, a coating film and further forming thereon an organic resin layer. The coating film contains a polyester resin having a glass transition temperature of 20 to 55°C, a phenol resin and an acid catalyst, in order to be able to provide the coated metal sheet further covered with the organic resin that is suited for producing cans and can lids having excellent applicability for producing cans and excellent dent resistance.
Abstract:
A gas barrier film includes a resin film base material, a layer made of an aqueous coating agent (A) which contains a hardener and has gas barrier properties and adhesiveness to the resin film base material, the layer made of the aqueous coating agent (A) being formed on at least one surface of the resin film base material, and at least one layer made of an aqueous coating agent (B) having a compounding ratio of a hardener smaller than that of the aqueous coating agent (A), the layer made of the aqueous coating agent (B) being formed on the layer made of the aqueous coating agent (A).
