Proposed is a tube container in which generation of scratches on a surface of the container can be prevented. The present tube container () includes a tube body () that defines a container space (S) for contents and that has a laminated structure. The tube body () includes: a cylindrical laminated sheet () in which both edges () of the sheet are butted together; and a reinforcing tape portion (reinforcing tape) provided on an inner surface of the laminated sheet () along a butted portion (). The laminate sheet () includes a high hardness protective layer () constituting an outermost layer, an outer polyethylene-based resin layer () formed on an inner side of the high hardness protective layer (), and an inner polyethylene-based resin layer () constituting an innermost layer, and the high hardness protective layer () has a pencil hardness of 3B or greater than 3B. The reinforcing tape portion () includes a polyethylene-based resin layer (outer reinforcing resin layer) as an outermost layer abutting against the inner surface of the laminate sheet ().

Tube container

A blow-molded container includes a container body having a body portion that forms a square shape in a cross-sectional view orthogonal to a container axis; and in-mold labels, which are integrally glued on outer peripheral surfaces of glued portions, ranging from corner surfaces to respective planar portions continuing on both sides of corner surfaces around the container axis, in body portion. Among front and back surfaces of in-mold labels, multiple recesses are formed over entire back surfaces, which are glued to the outer peripheral surfaces of the glued portions. When tensile elasticity of in-mold labels is E (MPa) and thickness of in-mold labels is t (mm), E&#xd7;tis 0.20 or less. When the radius of curvature of the corner surfaces is R (mm) and angle formed between the planar portions is &#x3b8; (&#xb0;) in a cross-sectional view of the glued portions, R&#xd7;&#x3b8;is 45000 or more.

Blow-molded container with in-mold label and method for manufacturing blow-molded container with in-mold label

A technical problem of this invention is to create in-mold labels that can be adhered to wide areas, including 3D curved areas, of the peripheral wall of a synthetic resin container in a high-grade state without air entrapment and/or wrinkling. A principal means of this invention to solve the technical problem described above is in-mold labels used as an inserted material and adhered to the outer peripheral wall of a container main-body concurrently when the main body is being molded, said labels including an adhesive layer to be adhered to the outer peripheral wall of the container main-body, wherein this adhesive layer has depressed portions on a back surface thereof, the depressed portions being formed by embossing and being disposed in a regular pattern.

In-mold labels and a labeled container

A tack label difficult to peel from a container in a processing environment with normal temperature water and easy to peel from the container in a processing environment with hot water and a plastic container. The tack label according to this invention includes a label base material, a printing layer formed on one surface of this label base material, and an adhesive layer formed on the surface of the other of a label base material. The adhesive layer comprises an adhesive that is difficult to dissolve under an environment with normal temperature water and easy to dissolve under a processing environment with hot water. The result is a tack label that is difficult to peel from the container in a washing process, but easy to peel in a regenerating process.

Tack labels and plastic containers with such tack labels

An easily regeneratable printed thermoplastic resin product is provided by printing it with a specific radiation-curable ink composition and curing the printed ink with radiation to form a cured ink film thereon. The ink composition comprises a vehicle mixture containing: (A) at least one linear polyester oligomer and/or polymer substantially free of an acid group and a polymerizable double bond on the linear polyester chain wherein 1 to 10 double bonds are pendent from the linear polyester chain, and/or mixture thereof, (B) at least one single double bond-containing carboxylic acid and/or ester and/or amide wherein the acid has at least one acid group, and/or mixture thereof, (C) a double bond-containing polycarboxylic ester wherein 2 to 10 acid groups are present and at least 2 double bonds are pendent from the carboxylic ester having 2 to 10 acid groups, (D) at least one double bond-containing fluorinated carboxylic ester, and/or block copolymer comprising a fluorinated alkyl group-containing polymer segment and a (meth)acrylic polymer segment, and/or block copolymer comprising a siloxane group-containing polymer segment and a (meth)acrylic polymer segment, and/or mixture thereof, (E) a double bond-containing carboxylic ester, having at least 2 double bonds and free of an acid group, provided that it is excluded from the above-mentioned ingredient (A), and (F) at least one single double bond-containing carboxylic ester and/or amide and/or imide free of an acid group, and/or mixture thereof, wherein the acid value of the vehicle mixture is from 5 to 100. The ink is useful in displaying and decorating trade names, designs, explanatory notes, bar code, etc. on specific thermoplastic products and the cured ink film is easily detachable with an aqueous alkali solution.
