Definitions
- the present invention relates to a method for producing a heat-shrinkable cylindrical label and a continuous heat-shrinkable cylindrical label.
- the present invention relates to a heat-shrinkable cylindrical label attached to a container or the like by heat shrinkage, and to a method for producing a continuous long cylindrical label in which the cylindrical labels are continuously connected.
- a heat-shrinkable cylindrical label (shrink label formed in a cylindrical shape) is used by being attached to a container such as a beverage container and a cosmetic container.
- a strong heat-shrinkable tubular label consists of a label base material provided with a heat-shrinkable synthetic resin sheet (sometimes called a film).
- the center seal portion is formed by overlapping and attaching the overlapped portion.
- Japanese Patent Application Publication No. 8-106252 discloses a heat-shrinkable sheet (expressed as a heat-shrinkable film in the same publication) and a foamed resin sheet (In this publication, a heat-shrinkable tubular label is described in which a label base material on which a heat-shrinkable foam sheet is laminated) is formed into a tubular shape and a center seal portion is formed.
- a large heat-shrinkable tubular label has a heat-insulating effect when laminated foamed resin sheets. Therefore, even if the container or the like to which the tubular label is attached is heated or cooled, the heat of the container or the like is hardly transmitted to the user, which is preferable.
- the one shown in FIG. 1 (a) has a problem that it is difficult to obtain sufficient adhesive strength with a small amount of adhesive because the adhesive 105 is applied to the foamed resin sheet 102. Furthermore, as pointed out in [0006] of the publication, the side edges of the foamed resin layer become oblique and exposed to the outside when the shrink is attached, and the appearance of the attachment is impaired.
- the above point is not a problem limited to a foamed resin sheet laminated on a heat-shrinkable sheet.
- a label base material on which nonwoven fabric, Japanese paper, etc. are laminated is used.
- a similar problem arises.
- the material of the heat-shrinkable sheet is different from the material of the foamed resin sheet / non-woven cloth, the two may not be able to be bonded with a solvent.
- the present invention relates to a heat-shrinkable cylindrical label in which a center-sealed portion is not thickened in a cylindrical label in which an inner layer sheet is laminated on the back surface of an outer layer sheet, and the cylindrical label continuous body.
- the purpose of the present invention is to provide a manufacturing method of the present invention. It is another object of the present invention to provide a heat-shrinkable tubular label having a beautiful appearance after mounting a shrink.
- the present invention relates to a label base material in which both ends of a label base material in which an inner layer sheet is laminated on the back surface of a heat shrinkable outer layer sheet are overlapped to form a cylinder, and a center seal portion is formed.
- An exposed outer layer sheet having no inner layer sheet is provided on the back side of the negative end of the material, and the exposed outer layer sheet and the surface of the other end of the label base material are overlapped with each other to form a solvent or an adhesive.
- the strong cylindrical label does not have an inner layer sheet, and the exposed portion of the outer layer sheet has the other side of the label substrate.
- a center seal portion is formed so as to overlap the surface of the end portion. Therefore, it is possible to prevent the inner sheet from being vertically overlapped in the center seal portion, and prevent the center seal portion from becoming thick. Therefore, after the shrink is attached, the inner seal sheet does not protrude from the outer edge of the center seal portion even with the swelling force of the center seal portion, and the outer appearance of the attachment label becomes beautiful.
- the outer layer sheet surfaces are in contact with each other, and both surfaces are adhered using a solvent or an adhesive, It can be easily and reliably attached. Further, since the adhesive or the like does not adhere to the inner layer sheet, the center seal portion does not become too hard.
- a center seal portion is formed by superimposing both end portions of a label base material having an inner layer sheet laminated on the back surface of a heat shrinkable outer layer sheet via an adhesive layer, thereby forming a center seal portion. That one side edge of the inner layer sheet is arranged inside the one side edge of the outer layer sheet and one side edge of the adhesive layer is arranged inside the one side edge of the inner layer sheet. Therefore, the exposed portion of the outer layer sheet is provided on the back surface of the -side end portion of the label base material, and the exposed portion of the outer layer sheet and the surface of the other side end portion of the label base material are superimposed and affixed with solvent or adhesive.
- a heat-shrinkable tubular label is provided.
- “inside” refers to the center in the width direction of the label base material.
- a strong cylindrical label has a thick center seal portion and is not hard, and the center seal portion can be easily formed.
- one side edge of the inner layer sheet is disposed inside the lower side edge of the outer layer sheet, and one side edge of the adhesive layer is formed on one side of the inner layer sheet. Since the label base material is disposed inside the edge, the base material thickness of the label base material becomes thinner at one end, and gradually increases inward from the one end. Therefore, the outer shape of the cylindrical label that faces inward from the center seal portion is a relatively gentle straight line or curve. For this reason, a cylindrical label with a beautiful outer peripheral surface shape can be provided.
- the present invention relates to a method in which a center seal portion is formed by superimposing both side edges of a label base material laminated in order of a design printing layer and an inner layer sheet on the back surface of an outer layer sheet having heat shrinkability.

- a strong cylindrical label has a thick center seal portion and is not hard, and the center seal portion can be easily formed. Furthermore, since the one side edge force of the design printing layer is arranged outside the inner layer sheet, one side edge of the inner layer sheet is hidden by the design printing layer. Therefore, the inner layer sheet on the outer peripheral surface of the cylindrical label cannot be seen, and the appearance of the attached label becomes more beautiful.
- the present invention relates to a center seal which is formed by laminating both side edges of a label base material having a design printing layer, an adhesive layer and an inner layer sheet laminated in this order on the back surface of a heat shrinkable outer layer sheet. Part is formed, one side edge of the design print layer is arranged inside one side edge of the outer layer sheet, and one side edge of the adhesive layer is arranged inside one side edge of the design print layer. In addition, since one side edge of the inner layer sheet is disposed between one side edge of the design printing layer and one side edge of the adhesive layer, the outer layer sheet is exposed on the back side of the-side end of the label base material.
- the heat-shrinkable cylindrical label is provided in which the exposed portion of the outer layer sheet and the surface of the other end of the label base material are overlapped with each other and adhered with a solvent or an adhesive.
- a strong cylindrical label has a thick center seal portion and is not hard, and the center seal portion can be easily formed. Further, since at least three layers of a design printing layer, an adhesive layer, and an inner layer sheet are provided on the back surface of the outer layer sheet, the thickness of the label base material is increased as compared with the cylindrical label, but Each layer is provided with a position shift inside. Therefore, the outer shape of the cylindrical label is a relatively gentle straight line or curve, and a cylindrical label with a beautiful outer peripheral surface shape can be provided.
- the side edge of the inner layer sheet at the other end of the label base material is located on the side of the inner layer sheet at the-end of the label base material.
- the heat-shrinkable tubular label is provided outside the edge.
- the inner layer sheet does not vertically overlap in the entire portion where the both side edges of the label base material are formed only by the center seal portion. Therefore, the cylindrical label It is possible to reliably prevent the occurrence of a thick portion in which a part of the tool rises.
- the heat-shrinkable tubular label in which the inner layer sheet includes a heat-insulating sheet the heat-shrinkable tubular label in which the inner layer sheet includes a foamed resin sheet, The heat-shrinkable tubular label, wherein the inner layer sheet includes a nonwoven fabric.
- Each of the heat-shrinkable cylindrical labels of this preferred embodiment has heat insulating properties. In general, a sheet having heat insulating properties is often thick, but in the center seal portion, the inner layer sheet does not overlap vertically./ In the present invention, the inner layer sheet is used. Even if a heat-insulating sheet is used, the bulging of the center seal portion can be prevented.
