Problems solved by technology

If the sealing label is peeled off after sticking the label on the adherend, it has preferable properties as a sealing paper whose label is easy to break, but the fracture surface is linear, and if the fracture surface Butting each other for re-attachment, there is a problem that it is difficult to distinguish the fracture surface

Embodiment 1

[0443] The resin composition b used as the base material layer (A) was melt-kneaded with an extruder set at 230° C., and then supplied to a T-die set at 250° C., from T The die is extruded into a sheet and cooled using a cooling device to obtain an unstretched sheet. This unstretched sheet was heated to 142° C., and stretched four times in the longitudinal direction by utilizing the difference in circumferential speed of the roll group to obtain a uniaxially stretched sheet.

[0444] In addition, resin composition e was used as the resin composition to be the surface layer (B), kneaded by an extruder set at 250° C., and then supplied to a T-die set at 250° C. Extrude into a sheet with a T-die, laminate one side of the uniaxially stretched sheet obtained in the step and cool to 60°C to obtain a base layer (A) / surface layer (B) (resin composition b / Two types of two-layer laminated sheets of resin composition e).

[0445] Next, heat the two double-layer laminated sheets obtain...

Embodiment 2～5

[0451] In Example 1, the heating temperature of the unstretched sheet to be the base material layer (A) was changed from 142°C to the temperature described in Table 2 when stretching the unstretched sheet in the longitudinal direction 4 times. Except that the heating temperature of the two-layer laminated sheet was changed from 148°C to the temperature listed in Table 2, in the same manner as in Example 1, the substrate layer (A) and The laminated film of each density of the surface layer (B), and using it, the labels of Examples 2-5 were obtained.

Embodiment 6

[0457] In Example 2, the T-die used for producing the unstretched sheet to be the base material layer (A) was set to two types of double-layer T-die, and the extruder set at 230° C. The resin composition b of the material layer (A1) (main layer) is melted and kneaded and extruded to a T-die. On the other hand, another extruder set at 230°C is used to form the base material layer (A2) The resin composition f (surface layer) was melt-kneaded and extruded to a T-die, and the two resin compositions were laminated in a T-die set at 250° C. Two kinds of double-layer unstretched sheets containing resin composition f and resin composition b were obtained in the same manner as in Example 2, except that the substrate layer (A1) / substrate layer (A2) / substrate layer (A2) / Three kinds of three-layer laminated films of the surface layer (B) (resin composition b / resin composition f / resin composition e) were obtained, and a label was obtained.

[0458] The overall thickness of the laminated ...

Abstract

A label including a base material layer (A) and an adhesive layer (C) provided so as to be in contact with one surface of the foregoing, wherein the label is characterized in that the base material layer (A) includes a thermoplastic resin and inorganic fine powder and / or an organic filler, the base material layer (A) being stretched in at least one axial direction; and the internal bond strength of a film, measured in accordance with TAPPI T569, is 0.4-0.95 kg cm on the adhesive layer (C) side and 0.4-1.5 kg*cm on a side opposite thereto, the label being easily determined with the naked eye to have been separated from a body to which the label was stuck and, once separated, being difficult to be restored by re-sticking.

Description

technical field [0001] The present invention relates to a label, a method for manufacturing the label, a method for using the label, and a labeled adherend. Specifically, it relates to a label that can be visually judged that the label has been peeled off by breaking the label when the label is bonded to the adherend and then peeled off, and that makes it difficult for the peeled label to return to its original shape. . Background technique [0002] Conventionally, various substitution-preventing labels have been proposed, and in order to prevent label substitution, the label itself is broken when the label is peeled off, and a part of the label remains on the adherend. [0003] For example, Cited Document 1 discloses a fragile label comprising a base material, a breaking layer, and an adhesive layer having a concavo-convex shape. When the label is peeled from the bonded adherend, the breakable layer is broken so that at least the portion of the adhesive layer correspondin...
