Abstract: [Problem to be Solved] An object of the present invention is to provide an aqueous writing tool for a food product packaging material, which can provide written products having high color developability and fixing properties upon writing on food product packaging materials. [Solution] An aqueous writing tool for a food product packaging material comprising an ink comprising two or more pigments and one or more dispersants, wherein at least one of the pigments being a white pigment, the total content of the pigments being 10 to 25% by mass based on the total amount of the ink, and the total content of the dispersants being 1 to 5% by mass based on the total amount of the ink.

Abstract: [Problem to be Solved] An aqueous writing tool for a food product packaging material, comprising an ink with which writing can be done on food product packaging materials without being repelled can be provided. [Solution] An aqueous writing tool for a food product packaging material comprising an ink comprising a pigment, wherein the ink has a contact angle with a food product packaging material of 30 to 46°.

Abstract: Provided is a film storage box, more particularly, a wrap film storage box in which a grip member for lifting the edge portion of a film is lifted in advance, the lift is maintained for a long period, and the grip member is highly durable against damage. The film storage box (or the wrap film storage box) is characterized in that the grip member is formed over the entire width of the front plate of the film storage box and is lifted in a curved shape by using a repulsive force generated by adhering an edge fold strip provided at the upper end edge of the front plate to the rear surface of the front plate, and durability is imparted by employing portions of the fold lines of the both side faces of the front plate as the both side portions of the grip member.

Abstract: The invention relates to the sequential biaxial stretching of a thin film made of a polylactic acid resin containing as large an amount of a plasticizer as 10 to 50 wt % and aims at solving the problematic grip failure in the widthwise stretching step which failure is caused by the lowering in film flatness occurring in gripping the film with clips continuously.
