Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-shrinkable polystyrene label to be attached to an object such as a container made of synthetic resin, glass or metal.

[0002]

2. Description of the Related Art
Japanese Patent Application Laid-Open No. 7-3247 discloses this type of heat-shrinkable label.
7, JP-A-8-92457 and JP-A-9-3285
No. 64 (hereinafter referred to as "the conventional publications"), a transparent elastomer obtained by dispersing a rubber-like elastic material in a continuous phase of a copolymer of a styrene monomer and a (meth) acrylate monomer. A heat-shrinkable label formed from rubber-modified polystyrene obtained by adding a terpene resin to high-impact polystyrene is known.

[0003] Each of the labels described in each of these conventional publications is different from that of the prior art in that it uses a rubber-modified polystyrene resin in which a terpene resin is added to transparent and high-impact polystyrene, although there are differences such as a difference in Vicat softening point. In common, it has transparency, high rigidity (strong stiffness) and low natural shrinkage (low ratio of natural shrinkage when stored at a temperature slightly higher than room temperature), which are favorable properties as labels. Since it does not contain chlorine, harmful substances are less likely to be generated even by waste incineration, and it has the advantage that it is preferable from an environmental point of view.

[0004] Such a label is formed into a predetermined shape in accordance with the object to be mounted, and is used by being attached to the object by heat shrinkage. On the other hand, when pouring out the contents in the mounted object or when separating and collecting the mounted object and the label, the label is removed by vertically cutting a part of the mounted label. Is done.

[0005] Usually, a label is provided with a cutting auxiliary portion such as a perforation or a cut tape in the longitudinal direction of the mounted object in order to easily separate and remove the label without using a tool such as a cutter knife or scissors. Is provided.

More specifically, as shown in FIG.
In the label body 10 (a cap seal label is shown as an example), for example, a tearing start part 12 defined by a pair of cuts 11, 11 is formed at the upper end edge as a cutting auxiliary part. Perforated below 14, 11
The label is cut along the perforations 14, 14 by pulling the tear starting point 12 downward at the time of opening or the like, so that the label is cut off. Is cut off, so that the label can be separated and removed from the mounted object 5.

However, the heat-shrinkable label made of rubber-modified polystyrene described in each of the above-mentioned conventional publications can easily divide the label even when the division assisting portions such as perforations 14, 14 are provided. There was a problem that it was not possible. That is, the label made of rubber-modified polystyrene has high transparency due to the addition of the terpene-based resin, but on the other hand, the stability of the tearing direction is extremely poor, so as shown by the two-dot chain line in FIG. However, the perforations 14, 14 do not match the cutting lines 16, 16 of the label at the time of division, and the division removing unit 15 is interrupted during the division, so that the label cannot be removed by one operation. there were.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a polystyrene-based heat-shrinkable label which can be easily cut off while retaining the advantages of a label made of rubber-modified polystyrene. I do.

[0009]

Means for Solving the Problems Therefore, as a result of repeated studies through repeated trial and error, the present inventors have found that a polystyrene-based heat-shrinkable label has a surface layer 2, 2 laminated on both outer sides of the intermediate layer 1. A transparent and high-impact material comprising a base material 3 having a structured structure, wherein the intermediate layer 1 is formed by dispersing a rubber-like elastic material in a continuous phase of a copolymer of a styrene-based monomer and a (meth) acrylate-based monomer. Formed by rubber-modified polystyrene in which a terpene resin is added to polystyrene, and the surface layers 2, 2 are formed.
Was found to be able to solve the above-mentioned problems by forming a styrene-butadiene block copolymer.

A heat-shrinkable polystyrene-based label having such a structure is used as an intermediate layer 1 made of rubber-modified polystyrene.
Since the surface layers 2 and 2 made of a styrene-butadiene block copolymer are laminated on each other, the tearing direction stability is good, and when the attached label is opened, for example, along the dividing auxiliary portion. And can be easily separated and removed. In particular, it is preferable that a perforation 8 for division is formed in the longitudinal direction Y of the label body 9 as in the means according to the third aspect, since the label can be divided and removed along the perforation 8.

Further, since the intermediate layer 1 is formed of rubber-modified polystyrene, it has the advantages of high transparency, high rigidity of the label, and a low natural shrinkage rate. Since it is mainly made of high-impact polystyrene, it is a commonly used resin.

Since the styrene-butadiene block copolymer forming the surface layers 2, 2 contributes to the stability of the label in the tear direction, the thickness of the surface layers 2, 2 is too small (relatively the intermediate layer). When the thickness of the surface layer 2 is too large, the ratio of the thickness of the intermediate layer 1 is relatively low, and the rigidity is low. This is not preferable because the label has a high natural shrinkage. In consideration of these, the ratio of the thickness of the surface layers 2 and 2 to the thickness of the base material 3 (the sum of the thickness of the surface layers 層 the thickness of the base material) is formed in the range of 0.2 to 0.4. In particular, it is more preferable that the ratio of the thickness of the surface layers 2, 2 to the thickness of the base material 3 is in the range of 0.25 to 0.35.

The thickness of the label is not particularly limited.
Generally, the thickness is about 0 to 60 μm. For example, in the case of a label in which the thickness of the base material 3 is formed to 50 μm, the thickness of one surface layer 2 is preferably formed to be 5 to 10 μm. More preferably, the thickness of the surface layer 2 is formed in the range of 6.25 to 8.75 μm.

As the rubber-modified polystyrene for forming the intermediate layer 1 of the present invention, those disclosed in each conventional publication may be used.

In brief, the styrene monomer of transparent and high-impact polystyrene (hereinafter sometimes referred to as "grafted TI-PS") includes, for example, styrene, α-methylstyrene, pt- Butylstyrene, p-methylstyrene and the like are used. In the present invention, these styrene monomers may be used alone or in combination of two or more.

As the (meth) acrylate monomer of the graft TI-PS, alkyl acrylate monomers, alkyl methacrylate monomers and the like are used.

For example, methyl acrylate, ethyl acrylate, n-butyl acrylate, i-butyl acrylate,
Monomers such as 2-ethylhexyl acrylate, n-octyl acrylate, methyl methacrylate, ethyl methacrylate, n-butyl methacrylate, i-butyl methacrylate, 2-ethylhexyl methacrylate, and n-octyl methacrylate, These monomers may be used alone or in combination. In the present invention, methyl acrylate or methyl methacrylate is preferably used as the (meth) acrylate-based monomer because of its excellent transparency, and an alkyl group having 4 or more carbon atoms such as n-butyl acrylate is preferably used. Alkyl methacrylate having an alkyl group having 4 or more carbon atoms, such as alkyl acrylate or n-butyl methacrylate, is preferably used because it is excellent in reducing the natural shrinkage.

Further, the rubbery elastic body of the grafted TI-PS refers to a rubbery elastic body which exhibits rubber elasticity at normal temperature. Examples thereof include dienes such as polybutadiene, styrene-butadiene copolymer, styrene-butadiene block copolymer, and the like.
An isoprene polymer or the like is used. Among them, styrene-
Butadiene copolymers and styrene-butadiene block copolymers are preferred.
More preferably, it is 50% by weight.

If the particle size of the rubber-like elastic material is too small, the shock absorption is poor, and if it is too large, it causes cloudiness. Therefore, in the present invention, the particle size is 0.1 to 1.2.
μm range, more preferably 0.1 μm.
It is preferably in the range of 0.7 μm.

The proportions of the styrene-based monomer, (meth) acrylate-based monomer and rubber-like elastic material are not particularly limited, and may be the proportions described in each of the prior art publications. When the monomer is 45 to 55
% By weight, the (meth) acrylate monomer is 3%
It is considered most preferable that the rubbery elastic body is polymerized at a ratio of 8 to 45% by weight and a rubbery elastic body at a ratio of 6 to 10% by weight because the suitable transparency, high rigidity and low natural shrinkage of the intermediate layer 1 are exhibited.

Next, the terpene resin added to the grafted TI-PS is, as described in each conventional publication, a d-limonene obtained from citrus cortex or an isomer of α-pinene obtained from raw pine resin. The dipentene and aromatic hydrocarbon obtained by the chemical reaction can be obtained by performing cationic polymerization using a Friedel-Crafts type catalyst (for example, aluminum chloride, boron trifluoride, etc.). Further, a hydrogenated terpene resin obtained by hydrogenating such a polymer is also included in the terpene resin of the present invention. Furthermore, C 5 petroleum resins such as a resin of 1,3-pentadiene mainly indene -
Styrene - terpene petroleum resin is also present invention, such as DCPD petroleum resins such as a resin of C 8 -C 10 systems tar petroleum resin, or a dicyclopentadiene entity such as methyl indene -α-methyl styrene copolymer The hydrogenated resin (hydrogenated petroleum resin) of the petroleum resin is also included in the terpene resin of the present invention.

Such a terpene resin is a transparent and high impact polystyrene (grafted TI-PS) in which a rubber-like elastic material is dispersed in a continuous phase of a copolymer of a styrene monomer and a (meth) acrylate monomer. 1 to 15 parts by weight is added to and mixed with 100 parts by weight.

In the present invention, as the intermediate layer 1,
A styrene-based monomer, a (meth) acrylate-based monomer, a rubber-like elastic body, and two or more copolymers having different proportions of a terpene-based resin may be laminated in two or more layers (a plurality of layers). .

Next, as the styrene-butadiene block copolymer forming the surface layers 2, 2, a commonly used styrene-butadiene block copolymer is used, and if necessary, a styrene-butadiene copolymer is used. A mixture of polystyrene may be used. The particle size of such butadiene is preferably in the range of 0.01 to 0.08 μm from the viewpoint of transparency.

The proportion of such a copolymer is not particularly limited, but it is preferred that the polymerization be carried out in a proportion of about 82 to 88% by weight of a styrene monomer and about 12 to 18% by weight of a butadiene monomer. In the present invention, as the surface layers 2, 2, two or more copolymers having different ratios of styrene-based monomer and butadiene-based monomer may be laminated in two or more layers.

[0026]

Embodiments of the present invention will be described below. In FIG. 1, reference numeral 3 denotes a terpene-based resin added to a transparent and high-impact polystyrene in which a rubber-like elastic material is dispersed in a continuous phase of a copolymer of a styrene-based monomer and a (meth) acrylate-based monomer. A substrate is shown in which surface layers 2, 2 made of a styrene-butadiene block copolymer are laminated on both outer sides (both surfaces) of an intermediate layer 1 made of rubber-modified polystyrene.

It should be noted that transparency between the intermediate layer 1 and the surface layers 2, 2
If the rigidity and the natural shrinkage property are not deteriorated, a resin layer of another copolymer or the like may be separately laminated.

As described above, the intermediate layer 1 is composed of, for example, 45 to 55% by weight of a styrene monomer, 38 to 45% by weight of a (meth) acrylate monomer,
Graft copolymer 10 polymerized at a ratio of 10 to 10% by weight
It is constituted by forming a resin in which 1 to 15 parts by weight of a terpene resin is added to 0 parts by weight to form a sheet.

As described above, the surface layers 2, 2 are formed, for example, in a sheet form from a block copolymer obtained by polymerizing 82 to 88% by weight of a styrene monomer and 12 to 18% by weight of a butadiene monomer. It is constituted by forming. Incidentally, if necessary, a lubricant, an antioxidant, an ultraviolet absorber, an antistatic agent and the like may be added to the intermediate layer 1 and the surface layers 2, 2.

The substrate 3 has a width of 3.5 to 3.5 in the width direction (that is, the circumferential direction X of the object 5 when the object 3 is mounted on the object 5 such as a container).
Stretching is performed about 5.0 times (see FIG. 2), and if necessary, 1.05 to 1.05 in the longitudinal direction (that is, the vertical direction Y of the object 5 when mounted on the object 5 such as a container). It is stretched about 1.50 times. The substrate 3 exhibits a shrinkage behavior in any direction at least within a temperature range of 80 ° C. or higher.

The base material 3 is formed in a cylindrical shape so that the width direction is the circumferential direction X of the mounted object 5, thereby forming a label body 9 that can be mounted on the mounted object 5.

On one surface of the base material 3 (the outer surface of the one surface layer 2 and the surface that is in contact with the object to be mounted 5), as a printing layer, for example, an acrylic base coat is formed by applying an aqueous base. An arbitrary design is printed using ink. On the other hand, a protective film made of, for example, an acrylic resin is formed as an overcoat layer on the other surface of the base material 3 (the outer surface of the other surface layer 2, which is not in contact with the object 5). ing.

Incidentally, gravure printing is preferable as the printing means. In addition, the above printing is performed using an aqueous ink on an acrylic base coat. For example, instead of the aqueous ink, an oil-based ink (a volatile organic solvent) that is often used in gravure printing or the like is used. (Including vehicle)
Base material 3 using an ink in which a colorant such as a pigment is dispersed in
May be directly printed on one side.

In the label of the prior art, since the base material is made of rubber-modified polystyrene, if the printing is directly performed using an oil-based ink, the terpene resin in the rubber-modified polystyrene is dissolved in the organic solvent in the oil-based ink. Although there is an inconvenience of deteriorating the base material, the polystyrene-based heat-shrinkable label according to the present invention has a surface layer 2, 2 made of a styrene-butadiene block copolymer which is laminated, so that the oil-based ink is directly used. There is an advantage that can be.

Further, the label body 9 may be provided with a division assisting part if necessary. For example, as shown in FIG.
A tear starting point portion 7 defined by a pair of cuts 6, 6 at the upper edge of the label body 9 and extending upward, and a pair of cutting perforations cut below the cuts 6, 6. A division assisting section having 8, 8 may be provided. As shown in the enlarged view of the figure, the perforations 8, 8 preferably have a cut portion 8a and a non-cut portion 8b each having a size of about 0.3 to 3 mm.

In the label according to the present invention, the surface layers 2, 2 made of a styrene-butadiene block copolymer having good tear direction stability are laminated on both surfaces of the intermediate layer 1, so that the tear initiation point 7 is located downward. , The label is cut along the perforations 8,8, and the label can be separated by one operation. Therefore, the label attached to the object can be easily removed. In addition, since the intermediate layer 1 is formed of rubber-modified polystyrene, the label is excellent in transparency, strong in stiffness, and extremely low in natural shrinkage during storage, so that the label has high practical value. It is.

<Manufacturing Method> Next, a method of manufacturing the heat-shrinkable label having the above structure will be described. The rubber-modified polystyrene and the styrene-butadiene block copolymer are supplied to separate extruders, melt-extruded at a temperature of about 200 ° C., and both streams are combined by a feed block.

This is introduced into a T-type die to form a three-layer sheet in which surface layers 2 and 2 are laminated on both outer sides of the intermediate layer 1. Next, the three-layer sheet is heated to about 90 ° C. to make the sheet in the width direction.
Stretch 8 times.

Thereafter, it is fixed in a heat treatment zone at 85 ° C. in a tensioned state, taken out of the tenter and cooled, and wound on a core to produce a substrate 3. In this case, the thickness of the intermediate layer 1 of the heat-shrinkable label is 34 μm, the thickness of the surface layers 2 and 2 is 8 μm, and the thickness of the base material 3 is 50 μm.

Next, a printing layer is formed on one surface of the base material 3 by gravure printing of a design consisting of eight colors using an aqueous ink, while the other surface of the base material 3 is used for preventing damage. For this purpose, an acrylic resin is applied to form an overcoat layer, which is wound up as a printing roll.

This printing roll is slit into an appropriate width to form a roll of one row, and the roll is formed such that the printing surface (one surface of the substrate 3) is on the inside and the width direction of the substrate 3 is Circumferential direction X
The heat-shrinkable label is manufactured by forming a long cylinder by bonding both sides to a solvent or the like to form a long cylinder, and cutting the long cylinder at a predetermined interval. In the case where the division assisting portion is provided, a division assisting portion such as a perforation is formed when the long cylindrical body is cut.

<Method of Use> The tubular heat-shrinkable label produced in this manner is supplied to an automatic label mounting apparatus, and a 1.5-liter container (so-called polyethylene terephthalate) filled inside as a mounting object 5 is used. (PET container), heat-shrinks by passing through a steam tunnel, and the label is attached to the PET container.
