The water-soluble resin for printing of the present invention includes a monomer unit A having a sulfonate group; and a monomer unit B having no hydrophilic group, and a percentage of the monomer unit A based on a total of all monomer units is 5 to 35 mol %. According to the water-soluble resin for printing of the present invention, a printed matter from which a printing layer can be safely and efficiently removed with neutral water and which is excellent in water resistance can be realized.

Water-soluble resin for printing

A sheet material container includes a container body that surrounds a containing portion for accommodating a content. The container body is formed of a container body-forming sheet member formed by layering a plurality of base material films. The container body-forming sheet member includes the plurality of base material films, an attaching layer by which the base material films are attached to each other, and a filler enclosed portion that is formed between the plurality of base material films and into which a filler is to be filled. The plurality of base material films are made from the same type of resins.

Sheet material container

Provided is a sheet for container to be used in a flexible container, the sheet for container having a plurality of films layered in the sheet for container, the sheet for container including: a first film including a first base-material layer, which is coated with a first applying-type gas barrier layer and made of a single type of material having a heat-sealing property; and a second film including a second base-material layer, which is coated with a second applying-type gas barrier layer and made of a single type of material that is a same type of material as the first base-material layer, in which: the first film and the second film are attached to each other by heat sealing; and a gas enclosing portion, which is partially non-attached and in which gas is able to be enclosed, is formed between the first film and the second film.

Sheet for container

A method for producing an injection-molded article of a polylactic acid resin composition, including filling a melt-kneaded product of a polylactic acid resin composition containing a polylactic acid resin, a plasticizer containing a polyoxyalkylene group or an oxyalkylene group, and a mold releasing agent having a melting point of from 20&#xb0; to 75&#xb0; C. in an injection-molding machine to mold in a die, wherein the method is characterized in that the above-mentioned injection-molding machine comprises a cylinder at least a part of which has a set temperature of 200&#xb0; C. or higher, that the die has a surface temperature of 85&#xb0; C. or higher, and that the die has a surface roughness of 1.0 &#x3bc;m or less.
