Description
本発明は、易剥離性ラベルに関し、更に詳しくは、配達確認・受領証として剥離した剥離伝票等のカールを改善した易剥離性ラベルに関する。 The present invention relates to an easily peelable label, and more particularly to an easily peelable label having improved curl of a peeling slip or the like peeled off as a delivery confirmation / receipt.
最近、インターネットショッピングやホームショッピングなどが発達して、購入者は宅配便によって商品を受け取ることが多い。このように購入された商品だけでなくデパートや一般の商店で買い物をした商品についても、宅配便会社に委託して購入者に届けられることが多い。このような商品は、ある企業から他の企業へ、企業からある個人へ、個人から他の個人へ配送される。この際、商品の包装には、配送用情報を記録するための宅配便用の送り状ラベルが貼付される。 Recently, with the development of Internet shopping and home shopping, purchasers often receive products by courier service. Not only the products purchased in this way, but also the products purchased at department stores and general stores are often outsourced to a courier company and delivered to the purchaser. Such goods are delivered from one company to another, from a company to an individual, and from an individual to another. At this time, an invoice label for courier service for recording delivery information is affixed to the packaging of the product.
このような宅配便用送り状ラベルは、一般に発送元の記載と受取人の住所、氏名及び商品名、規格、数量などの記録が記載され、受取人が受領したことを確認する引き取り証として剥離したラベルは配送会社に回収される。同様の記録は、剥離した後の残留ラベルは商品の包装にも残ることがあるが、最近は残らない形式もある。 Such a courier invoice label generally contains a description of the sender and a record of the recipient's address, name and product name, standard, quantity, etc., and is peeled off as a receipt confirmation that the recipient has received it. The label will be collected by the shipping company. Similar records show that residual labels after peeling may remain on the packaging of the product, but in some formats these days they do not.
このような宅配便用送り状ラベルの構造は、一般的には、表面に印刷が可能な感熱紙層と感熱紙の裏面に一般的なアクリル系溶剤型の粘着剤を塗布した粘着層と、粘着層に貼り付けられ、表面がシリコーンコート処理された剥離紙層とからなる。感熱紙は熱によって印刷が行われ、剥離紙層はシリコーン層とグラシン紙からなり感熱紙の表面には差出人、受取人、商品の種類、費用、最終伝達場所、引受後の引き受け確認を記録するための部分が熱により印刷される。そして、感熱紙層は発送元用の回収ラベルと受取人用の残留ラベルからなることが一般的である。
しかし、従来の宅配便用送り状ラベルは、回収ラベルを粘着層から剥離すると背面や残留ラベルの表面に粘着層のべたつきが残ったり、それが汚れの原因になったりして回収ラベルや残留ラベルの管理に不便を来すことがある。
The structure of such a delivery label for courier is generally a heat-sensitive paper layer capable of printing on the front surface, an adhesive layer coated with a general acrylic solvent-type adhesive on the back surface of the heat-sensitive paper, and adhesive. It consists of a release paper layer that is affixed to the layer and whose surface is silicone coated. The thermal paper is printed by heat, and the release paper layer consists of a silicone layer and glassin paper. The sender, recipient, product type, cost, final transfer location, and acceptance confirmation after acceptance are recorded on the surface of the thermal paper. The part for is printed by heat. The thermal paper layer is generally composed of a collection label for the sender and a residual label for the recipient.
However, with conventional invoice labels for courier services, when the collection label is peeled off from the adhesive layer, the adhesive layer may remain sticky on the back surface or the surface of the residual label, which may cause stains. It may be inconvenient to manage.
剥離紙原紙として、原紙の表面にポリエチレンのラミネート層と剥離剤層を設けた剥離紙原紙の裏面に、ワックスエマルジョン、スチレンアクリル共重合体アンモニウム塩、スチレンブタジエンラテックスなどを塗工した剥離紙原紙が耐カール性に優れることが開示されている（特許文献１）。
また、紙基材の裏面に樹脂層を設けてなる配送伝票で、これら２層に接着部と疑似接着部を設けその境界線に切込みを設けて疑似接着部分をはぎ取り受領票とする使用法が開示されている（特許文献２）。
As the release paper base paper, a release paper base paper in which a polyethylene laminate layer and a release agent layer are provided on the front surface of the base paper and a wax emulsion, a styrene-acrylic copolymer ammonium salt, a styrene-butadiene latex, etc. are coated on the back surface of the release paper base paper is used. It is disclosed that it has excellent curl resistance (Patent Document 1).
In addition, in a delivery slip in which a resin layer is provided on the back surface of a paper base material, an adhesive portion and a pseudo-adhesive portion are provided in these two layers, a notch is provided at the boundary line, and the pseudo-adhesive portion is peeled off and used as a receipt slip. It is disclosed (Patent Document 2).
しかしながら、引用文献１の剥離紙原紙は原紙を静置した際に裏面からの水分吸収により生じるカール現象を改善するものであって、剥離した後のカール現象を改善するものではない。
また、引用文献２は疑似接着部を剥離して受領票とするもので、剥離後の受領票のカール現象は改善されない。
本発明は上記問題点を解消するもので、配送用送り状ラベルに限らず、易剥離性ラベルとして下地層から剥離されたときに印刷などで情報が記載されたラベルが剥離後にカールして情報が読み取りにくくなったり、嵩高になって管理上不便をきたすという課題を解決するものである。
However, the release paper base paper of Cited Document 1 improves the curl phenomenon caused by water absorption from the back surface when the base paper is allowed to stand, and does not improve the curl phenomenon after peeling.
Further, in Cited Document 2, the pseudo-adhesive portion is peeled off to obtain a receipt slip, and the curl phenomenon of the receipt slip after peeling is not improved.
The present invention solves the above problems, and is not limited to the delivery label, but when the label is peeled from the base layer as an easily peelable label, the label on which the information is written by printing or the like is curled after peeling and the information is displayed. It solves the problems of being difficult to read and becoming bulky, causing inconvenience in management.
本発明者らは、上記課題を解決するため鋭意研究を行った結果、基材層と樹脂層との接着強度の高接着部分と非接着又は弱接着部分とを混在させることにより、剥離した基材層のカールを改善できることを見い出し、本発明を完成するに至った。 As a result of diligent research to solve the above problems, the present inventors have separated a group by mixing a high-adhesive portion and a non-adhesive or weak-adhesive portion between the base material layer and the resin layer. We have found that the curl of the material layer can be improved, and have completed the present invention.

本発明の易剥離性ラベルは、基材層と樹脂層とからなる易剥離性ラベルであって、前記基材層と前記樹脂層との接着強度の強接着部分と非接着又は弱接着部分とが混在していることを特徴とする。 The easily peelable label of the present invention is an easily peelable label composed of a base material layer and a resin layer, and includes a strong adhesive portion and a non-adhesive or weak adhesive portion of the adhesive strength between the base material layer and the resin layer. Is characterized by being mixed.
基材層としては、印刷性や筆記性を有する紙、合成樹脂等が挙げられるが、特に感熱紙やインクジェット紙が好ましい。
感熱紙は熱に反応して黒色など発色するように加工された印刷用紙で、印刷が簡単で、広く用いられている。本発明では日本製紙（株) 製、王子製紙（株) 製、三菱製紙（株) 製など、通常の市販の感熱紙が使用できる。代表的な感熱紙としては、日本製紙（株) 製のＦＩ紙、王子製紙（株) 製のＤＬ８２ＡＳなどが挙げられる。
インクジエット紙はインクジエット印刷がしやすく、インクの発色が良くなるように表面にインクがのりやすくインクの吸収が良く乾燥が速くなるように表面加工されたものである。一般に広く販売されているものが使用できる。
Examples of the base material layer include paper having printability and writability, synthetic resin, and the like, and thermal paper and inkjet paper are particularly preferable.
Thermal paper is a printing paper that has been processed so that it develops a color such as black in response to heat. It is easy to print and is widely used. In the present invention, ordinary commercially available thermal paper such as Nippon Paper Industries Co., Ltd., Oji Paper Co., Ltd., and Mitsubishi Paper Mills Limited can be used. Typical thermal papers include FI paper manufactured by Nippon Paper Industries Co., Ltd. and DL82AS manufactured by Oji Paper Co., Ltd.
Ink jet paper is surface-processed so that ink jet printing is easy, ink is easily applied to the surface so that the color of the ink is good, ink absorption is good, and drying is quick. Those that are widely sold to the general public can be used.
樹脂層としては、ポリエチレン、ポリプロピレン等のポリオレフィン系樹脂、ポリスチレン樹脂、ポリエステル樹脂、ポリアミド樹脂等が挙げられるが、特にポリエチレン樹脂が好ましい。
樹脂層に用いられるポリエチレン樹脂は、包装紙して使用されるクラフト紙などに塗布された粘着剤への密着性を高め、配送品の到達時には感熱紙の剥離を可能にし、表面に印刷などで記載された感熱紙部分を受領書として利用させるものである。ポリエチレン樹脂としては、高密度ポリエチレン、中密度ポリエチレン、低密度ポリエチレン、超低密度ポリエチレン、その他変性ポリエチレンなど通常の一般的な市販の樹脂が使用できる。上記の粘着剤への密着性と感熱紙又はインクジエット紙の剥離性の点で中密度ポリエチレン、低密度ポリエチレン、超低密度ポリエチレンが好ましい。
Examples of the resin layer include polyolefin resins such as polyethylene and polypropylene, polystyrene resins, polyester resins, polyamide resins and the like, and polyethylene resins are particularly preferable.
The polyethylene resin used for the resin layer enhances the adhesion to the adhesive applied to kraft paper used as wrapping paper, enables the thermal paper to be peeled off when the delivered product arrives, and is printed on the surface. The described thermal paper part is used as a receipt. As the polyethylene resin, ordinary general commercially available resins such as high-density polyethylene, medium-density polyethylene, low-density polyethylene, ultra-low-density polyethylene, and other modified polyethylene can be used. Medium-density polyethylene, low-density polyethylene, and ultra-low-density polyethylene are preferable in terms of adhesion to the above-mentioned pressure-sensitive adhesive and peelability of thermal paper or ink jet paper.
樹脂層と基材層の積層は特に限られるものではないが、樹脂の溶融押出による押出ラミネートが便利である。樹脂の中では、中密度ポリエチレン、低密度ポリエチレン、超低密度ポリエチレン、変性ポリエチレンなどがラミネート加工性が良い。変性ポリエチレンなど、常温で粘着性の強いものはラミネート加工の作業性や加工品の取り扱いの点で難がある。樹脂層の厚さは、１５〜２５μｍが好ましい。 Lamination of the resin layer and the base material layer is not particularly limited, but extrusion lamination by melt extrusion of the resin is convenient. Among the resins, medium-density polyethylene, low-density polyethylene, ultra-low-density polyethylene, modified polyethylene, and the like have good laminating workability. Those with strong adhesiveness at room temperature, such as modified polyethylene, have difficulty in laminating workability and handling of processed products. The thickness of the resin layer is preferably 15 to 25 μm.
基材層と樹脂層の接着強度の強接着部分と非接着又は弱接着部分を混在させる方法としては、いくつかの方法がある。
その代表的な方法としては、ロール状の基材をロールから繰り出しながら、樹脂をＴ−ダイ押出機から溶融押出を行い、樹脂を基材の裏面（例えば、感熱紙の場合は、感熱発色面の反対面）上にラミネートを行うものである。その際、溶融状態のフィルム状の樹脂を基材に接触させ圧着ロールで挟圧するが、この圧着ロールの片方または両方に凹凸の表面をつくり圧着強度の差を設けておいて、これを冷却しロール状の製品に接着強度の強接着部分と非接着又は弱接着部分を混在させる。ロール表面の凸部に当たる部分が強接着部分、凹部に当たる部分が非接着又は弱接着部分となる。
その他、接着補助剤や弱接着剤を分散して部分的に塗布する方法などがある。
表面に凹凸模様をつけたロールを用いる方法は、ロール面の凸部と凹部の面積比がコントロールしやすく便利である。
また、接着強度のコントロールは、樹脂の押出機内樹脂温度、ダイス温度、Ｔ−ダイ押出機の後で基材層と樹脂層を挟圧する圧着ロールの圧着強度、ロールの凹凸部分の高低差などで調節できる。
There are several methods for mixing the strong adhesive portion and the non-adhesive or weak adhesive portion of the adhesive strength between the base material layer and the resin layer.
As a typical method, the resin is melt-extruded from a T-die extruder while the roll-shaped base material is drawn out from the roll, and the resin is subjected to melt extrusion on the back surface of the base material (for example, in the case of thermal paper, the heat-sensitive color-developing surface). It is laminated on the opposite side). At that time, the melted film-like resin is brought into contact with the base material and pressed by a crimping roll. On one or both of the crimping rolls, an uneven surface is formed to provide a difference in crimping strength, and this is cooled. A roll-shaped product is mixed with a strong adhesive portion having an adhesive strength and a non-adhesive or weak adhesive portion. The portion of the roll surface that corresponds to the convex portion is a strongly bonded portion, and the portion that corresponds to the concave portion is a non-adhesive or weakly bonded portion.
In addition, there is a method in which an adhesive auxiliary agent or a weak adhesive is dispersed and partially applied.
The method of using a roll having an uneven pattern on the surface is convenient because the area ratio of the convex portion and the concave portion of the roll surface can be easily controlled.
The adhesive strength is controlled by the resin temperature inside the resin extruder, the die temperature, the crimping strength of the crimping roll that sandwiches the base material layer and the resin layer after the T-die extruder, and the height difference of the uneven portion of the roll. Can be adjusted.
基材層と樹脂層との強接着部分の接着強度が０．１〜０．３Ｎ／５０ｍｍであることが基材層の剥離後のカール抑制の点で好ましい。
一方、基材層と樹脂層との非接着又は弱接着部分の接着強度は０〜０．１Ｎ／５０ｍｍであることが基材層の剥離後のカール抑止の点で好ましい。
尚、強接着強度と非接着又は弱接着強度の範囲が０．１Ｎ／５０ｍｍで重複しているが、これらの範囲内で強接着強度と非接着又は弱接着強度となるように選択される。
It is preferable that the adhesive strength of the strongly bonded portion between the base material layer and the resin layer is 0.1 to 0.3 N / 50 mm from the viewpoint of suppressing curl after peeling of the base material layer.
On the other hand, the adhesive strength of the non-adhesive or weakly adhered portion between the base material layer and the resin layer is preferably 0 to 0.1 N / 50 mm from the viewpoint of suppressing curl after peeling of the base material layer.
Although the ranges of strong adhesive strength and non-adhesive or weak adhesive strength overlap at 0.1 N / 50 mm, they are selected so as to have strong adhesive strength and non-adhesive or weak adhesive strength within these ranges.
接着強度の測定は、ＪＩＳ Ｋ６８５４−１９７７「接着剤のはく離接着強さ試験法」で、但し、次のように一部変更して測定される１８０度剥離法による。５０×１５０ｍｍの短冊状のサンプルの基材層の面をクラフト紙で固定し、３００ｍｍ／分の剥離速度で測定する。
強接着部分と非接着又は弱接着部分との比率は、３０：７０〜６０：４０であることが好ましい。
The adhesive strength is measured by JIS K6854-1977 "Adhesive peeling adhesive strength test method", but by the 180 degree peeling method which is measured with some modifications as follows. The surface of the base material layer of the 50 × 150 mm strip-shaped sample is fixed with kraft paper, and the measurement is performed at a peeling rate of 300 mm / min.
The ratio of the strongly bonded portion to the non-bonded or weakly bonded portion is preferably 30:70 to 60:40.
易剥離性ラベルを包装材等の被着体に残留させるために、樹脂層の基材層との反対側に粘着剤層を設けることができる。粘着剤層は通常の粘着剤を用いて塗布したり、押出ラミネート塗工によって設けることができる。粘着剤は、ゴム系粘着剤、アクリル系粘着剤、シリコーン系、ウレタン系粘着剤などが使用できるが、ゴム系は粘着力が安定し対象の被着体の選択性が少ない点で好ましい。また、アクリル系は耐熱性、耐候性に優れている。但し、被着体にはやや選択性がある。いずれも市販の粘着剤が使用できる。 An adhesive layer can be provided on the opposite side of the resin layer from the base material layer in order to leave the easily peelable label on the adherend such as a packaging material. The pressure-sensitive adhesive layer can be applied using a normal pressure-sensitive adhesive or can be provided by extrusion laminating coating. As the adhesive, a rubber adhesive, an acrylic adhesive, a silicone adhesive, a urethane adhesive, or the like can be used, but the rubber adhesive is preferable because the adhesive strength is stable and the selectivity of the target adherend is low. In addition, the acrylic type has excellent heat resistance and weather resistance. However, the adherend has some selectivity. Commercially available adhesives can be used for both.
本発明の易剥離性ラベルは、宅配便などで使用される。配送先（受取人）などラベル表面に印刷し商品を包装した包装紙などの包装材の表面に使用される。粘着剤層は本発明のラベルを包装材表面に貼付するために便利である。従って、この場合は配達時に配送人が易剥離性ラベルの基材層を剥がし取り配送確認の確認証として使用するとともに、一部を受取人の包装材に残留させることができる。この場合、粘着剤の被着体への接着強度は、配送確認証として剥離して回収する際に、残留ラベルを被着体（包装紙）に残留させるためには、易剥離ラベルの基材層の樹脂層への接着強度よりも高いほうが好ましい。 The easily peelable label of the present invention is used for courier services and the like. It is used on the surface of packaging materials such as wrapping paper that is printed on the surface of labels such as delivery destinations (recipients) and wraps products. The pressure-sensitive adhesive layer is convenient for attaching the label of the present invention to the surface of the packaging material. Therefore, in this case, the delivery person can peel off the base material layer of the easily peelable label at the time of delivery and use it as a confirmation certificate of delivery confirmation, and a part of it can be left in the packaging material of the recipient. In this case, the adhesive strength of the adhesive to the adherend is such that when the adhesive is peeled off and collected as a delivery confirmation, the residual label remains on the adherend (wrapping paper), so that the base material of the easily peelable label can be used. It is preferably higher than the adhesive strength of the layer to the resin layer.
本発明の易剥離性ラベルは、基材層と樹脂層の他に、必要に応じ、更に基材層や樹脂層等を含んでもよく、また、粘着剤層には離型層を積層し、包装材に貼着する際に離型層を剥離除去し粘着剤層を露出させて貼着することができる。 The easily peelable label of the present invention may further contain a base material layer, a resin layer, etc., if necessary, in addition to the base material layer and the resin layer, and a release layer is laminated on the pressure-sensitive adhesive layer. When affixed to the packaging material, the release layer can be peeled off and the adhesive layer can be exposed and affixed.
以下、実施例を挙げ本発明を更に説明するが、本発明は何ら実施例により制限されるものではない。
易剥離性ラベルの作成：
ロール状の感熱紙に溶融押出法によってポリエチレン樹脂をラミネートし、凹凸のある圧着ロールで挟圧してロール状の易剥離性ラベルを作成した。
接着強度の測定：
１．０ｃｍ×１．０ｃｍ角の市松模様の凹凸のついたゴム製ロール、その一部を幅１０ｃｍの流れ方向の深さが６００μｍの溝をつけ凹面に当たる部分から非接着又は弱接着強度を測るサンプルを切り出し、凸部に当たる部分から強接着強度を測るサンプルを切り出した。
ラベルのカールの評価：
包装紙に相当するクラフト紙の表面に粘着剤を塗布し、５０ｍｍ×１５０ｍｍに裁断した易剥離性ラベル（感熱紙にポリエチレン樹脂をラミネート）を圧着した後、ラミネートしたポリエチレン樹脂層を粘着剤層とともにクラフト紙表面に残して、表面の感熱紙だけを人の手で剥離した。剥離速度は通常の配送人がラベルを剥離する程度の速度で剥離した。環境温度は２５℃、相対湿度は４５％程度とした。
剥離後の感熱紙だけになったラベルを水平な木製のテーブルの上において、剥離後の感熱紙の反りの程度を判定した。側面からみると剥離したラベルは円形または楕円形となり、側面で観察した円形または楕円形の最高部のテーブル面からの高さで判定した。高さが高いほどカールが改善されていると判定した。
Hereinafter, the present invention will be further described with reference to examples, but the present invention is not limited to any examples.
Easy-to-peel label creation:
A polyethylene resin was laminated on a roll-shaped thermal paper by a melt extrusion method, and pressed by a pressure-bonding roll having irregularities to prepare a roll-shaped easily peelable label.
Adhesive strength measurement:
A rubber roll with a checkered pattern of 1.0 cm x 1.0 cm square, a part of which is 10 cm wide and has a groove with a depth of 600 μm in the flow direction, and the non-adhesive or weak adhesive strength is measured from the part that hits the concave surface. A sample was cut out, and a sample for measuring the strong adhesive strength was cut out from the portion corresponding to the convex portion.
Label curl rating:
An adhesive is applied to the surface of kraft paper, which corresponds to wrapping paper, and an easily peelable label (laminated with polyethylene resin on thermal paper) cut into 50 mm x 150 mm is crimped, and then the laminated polyethylene resin layer is combined with the adhesive layer. Only the thermal paper on the surface was peeled off by hand, leaving it on the surface of the kraft paper. The peeling speed was such that a normal delivery person peeled the label. The environmental temperature was 25 ° C. and the relative humidity was about 45%.
The degree of warpage of the thermal paper after peeling was determined by placing the label containing only the thermal paper after peeling on a horizontal wooden table. When viewed from the side, the peeled label became circular or oval, and was judged by the height from the table surface at the highest part of the circular or oval observed on the side. It was judged that the higher the height, the better the curl.
