【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、上記したような従来の剥離紙においては、ベース基材5'より剥離後 の剥離紙1'は、その基紙2'と合成樹脂ラミネート層3'とは、その接着強度が一般 に大きく接着状態であるので、それぞれ分離回収できないものである。それ故、 不要となった剥離紙はそのまま廃棄処分されることとなり、廃棄公害ならびに昨 今問題となっている地球環境保護(エコロジー)などの観点から問題視されるこ ととなっている。 By the way, in the conventional release paper as described above, the release paper 1'after release from the base material 5'has a generally large adhesive strength between the base paper 2'and the synthetic resin laminate layer 3 '. Since they are in a bonded state, they cannot be separated and collected. Therefore, the release paper that is no longer needed will be discarded as it is, and it will be regarded as a problem from the perspective of waste pollution and global environmental protection (ecology), which has become a problem recently.

【0004】 従って、本考案の目的とするところは、ベース基材より剥離後の剥離紙が、そ の合成樹脂ラミネート層と基紙とが容易に剥離分断可能であり、両部材がそれぞ れ回収・再生(リサイクル)可能な剥離紙を提供することを目的とする。Therefore, the object of the present invention is that the release paper after peeling from the base material can easily separate and separate the synthetic resin laminate layer and the base paper, and both members are respectively separated. The purpose is to provide a release paper that can be collected and recycled (recycled).

【課題を解決するための手段】 本考案は、上述した従来技術の課題ならびに目的に鑑み考案なされたものであ って、その構成要旨とするところは、 ベース基材の粘着層側に、剥離層を介して仮着状態で貼着される剥離紙であっ て、 基紙と、基紙上にラミネートされた合成樹脂ラミネート層と、合成樹脂ラミネ ート層上に設けられた剥離層とから構成され、 前記基紙と合成樹脂ラミネート層との間が仮貼着状態であるように、合成樹脂 ラミネート層が基紙上にラミネートされ、 前記基紙と合成樹脂ラミネート層との間の接着強度が、ベース基材の粘着層と 剥離紙の剥離層との間の接着強度よりも大きいことを特徴とする剥離紙である。Means for Solving the Problems The present invention has been devised in view of the problems and objects of the above-mentioned conventional technology, and the gist of the constitution is that the adhesive layer side of the base substrate is peeled off.

【実施例】【Example】

以下、本考案の剥離紙について、添付図面に基づいてより詳細にその構成を説 明する。 Hereinafter, the structure of the release paper of the present invention will be described in more detail with reference to the accompanying drawings.

【0007】 図 1(a) は、本考案の剥離紙の部分拡大断面図であり、1は全体で本考案の剥 離紙を示している。剥離紙1は、基紙2と該基紙2上に仮着状態となるようにラ ミネートされた合成樹脂ラミネート層3と、合成樹脂ラミネート層3上に塗設さ れたシリコンコートなどから成る剥離層4とから構成されるものである。そして 、この剥離層4を介して、別途準備したベース基材5の粘着層6側に、仮着状態 で貼着されるものである。FIG. 1 (a) is a partially enlarged sectional view of the release paper of the present invention, and 1 indicates the release paper of the present invention as a whole. The release paper 1 is composed of a base paper 2, a synthetic resin laminate layer 3 laminated on the base paper 2 so as to be in a temporary attachment state, and a silicone coat applied on the synthetic resin laminate layer 3. It is composed of the peeling layer 4. Then, via the release layer 4, the base material 5 prepared separately is attached to the adhesive layer 6 side in a temporarily attached state.

【0008】 さらに、この場合、基紙2と合成樹脂ラミネート層3との間の接着強度が、ベ ース基材5の粘着層6と剥離紙1の剥離層4との間の接着強度よりも大きいこと が重要である。すなわち、使用に際して剥離紙1をベース基材5から剥がす際に 、ベース基材5の粘着層6と剥離紙1の剥離層4との間で剥離し、剥離紙1の基 紙2と合成樹脂ラミネート層3との間では剥離せずに、剥離紙1をベース基材5 から剥がすことができ、剥離後において、剥離紙1が、図1(b) に示したように 、基紙2と合成樹脂ラミネート層3との間で、剥離・分断できるように構成する のが重要である。Further, in this case, the adhesive strength between the base paper 2 and the synthetic resin laminate layer 3 is better than the adhesive strength between the adhesive layer 6 of the base substrate 5 and the release layer 4 of the release paper 1. Is also important. That is, when the release paper 1 is peeled off from the base material 5 in use, it is peeled off between the adhesive layer 6 of the base material 5 and the release layer 4 of the release paper 1, and the base paper 2 of the release paper 1 and the synthetic resin. The release paper 1 can be peeled off from the base material 5 without peeling from the laminate layer 3, and after peeling, the release paper 1 becomes the base paper 2 as shown in FIG. 1 (b). It is important that the synthetic resin laminate layer 3 and the synthetic resin laminate layer 3 can be separated and separated.

【0009】 また、このように、基紙2と合成樹脂ラミネート層3との間が仮貼着状態であ るように、合成樹脂ラミネート層3が基紙2上にラミネートされているが、この ためには、例えば、基紙2上にポリエチレンなどの合成樹脂を約200 ℃前後で押 出しラミネートすれば良い。なお、この場合、樹脂押出し温度を約200 ℃前後と 設定したのは、樹脂押出し温度が、例えば約300 ℃程度の高温である場合には、 基紙上に樹脂ラミネート層が完全に接着してしまい、逆に、樹脂押出し温度が、 例えば約170 ℃程度と比較的低い場合には、樹脂の押出し性に問題があり、各温 度における樹脂の押出し性と仮貼着性を考慮して、実験的に約200 ℃前後の時が 最も良好な結果をもたらすことになるからである。Further, the synthetic resin laminate layer 3 is laminated on the base paper 2 so that the space between the base paper 2 and the synthetic resin laminate layer 3 is temporarily attached in this way. For this purpose, for example, a synthetic resin such as polyethylene may be extrusion-laminated on the base paper 2 at about 200 ° C. In this case, the resin extruding temperature was set to about 200 ° C because the resin laminating layer is completely adhered to the base paper when the resin extruding temperature is high, for example, about 300 ° C. Conversely, if the resin extrusion temperature is relatively low, for example, about 170 ° C, there is a problem with the resin extrudability. Considering the resin extrudability and temporary adhesion at each temperature, an experiment was conducted. This is because the best results are obtained at about 200 ° C.

【0010】 また、この仮着状態とする別の方法としては、感熱接着性を有する樹脂、例え ばホットメルト系のエチレン−酢酸ビニルコポリマーなどを押出しラミネート、 又はフィルム状として、これをドライラミネート用接着剤(塗布量0.3 〜0.5 g/ m2) でドライラミネートしたものでも良い。これら以外の方法でも、要するに、 前述したように、使用に際してベース基材5の粘着層6と剥離紙1の剥離層4と の間で剥離し、剥離後において、剥離紙1の基紙2と合成樹脂ラミネート層3と の間では剥離できるような仮着状態にできる方法であれば良い。Further, as another method for making this temporary attachment state, a resin having a heat-sensitive adhesive property, for example, a hot-melt type ethylene-vinyl acetate copolymer is extruded and laminated, or is made into a film and is used for dry lamination. It may be dry-laminated with an adhesive (application amount: 0.3 to 0.5 g / m 2 ). In any other method, as described above, in other words, as described above, the adhesive layer 6 of the base substrate 5 and the release layer 4 of the release paper 1 are peeled off, and after peeling, the base paper 2 of the release paper 1 is removed. Any method may be used as long as it can be in a temporarily attached state such that it can be peeled off from the synthetic resin laminate layer 3.

【0011】 さらに、基紙としてはクラフト紙などが好ましく、ラミネートに供される合成 樹脂としては、ポリエチレンなどのポリオレフィン、ポリエステルなどの熱可塑 性樹脂、ホットメルト系樹脂などを条件に応じて適宜選択すればよい。Further, kraft paper or the like is preferable as the base paper, and polyolefin such as polyethylene, thermoplastic resin such as polyester, hot melt resin, or the like is appropriately selected as the synthetic resin used for lamination depending on conditions. do it.

【0012】 なお、本実施例の場合に、剥離紙1はベース基材5と貼着した状態であるが、 通常、剥離紙1は、ベース基材5に貼着する前には、ロール状に巻き取っておく などにより、適宜保管されることは勿論である。In the case of this embodiment, the release paper 1 is in a state of being adhered to the base substrate 5, but the release paper 1 is usually in a roll shape before being adhered to the base substrate 5. Of course, it can be stored appropriately by winding it up.

【0013】[0013]

【作用】 このように構成される本考案の剥離紙1は、図1(a) のように、別途用意した ベース基材5の粘着層6側に、剥離紙1の剥離層4を介して、仮着状態で貼着さ れる。そして、ベース基材5の使用に際して、剥離紙1全体をその剥離層4面に おいてベース基材5から剥がして使用する。また、不要となった剥離紙1は、図 1(b) に示したように、基紙2と合成樹脂ラミネート層3との間で剥離・分断し 、それぞれ両部材を回収・再生利用することができる。The release paper 1 of the present invention having the above-described structure is, as shown in FIG. 1 (a), provided with the release layer 4 of the release paper 1 on the adhesive layer 6 side of the separately prepared base substrate 5. , It is attached in a temporarily attached state. When the base material 5 is used, the entire release paper 1 is peeled from the base material 5 on the surface of the release layer 4 and used. Also, as shown in Fig. 1 (b), the unnecessary release paper 1 is separated and divided between the base paper 2 and the synthetic resin laminate layer 3, and both members are collected and recycled. You can

【効果】【effect】

本考案の剥離紙によれば、基紙2と基紙2上に仮着状態となるようにラミネー トされた合成樹脂ラミネート層3と、合成樹脂ラミネート層3上に塗設されたシ リコンコートなどから成る剥離層4とから構成し、基紙2と合成樹脂ラミネート 層3との間の接着強度が、剥離層を介して仮着状態で貼着されるべきベース基材 5の粘着層6と剥離紙1の剥離層4との間の接着強度よりも大きくしたので、 使用に際して剥離紙1をベース基材5から剥がす際に、ベース基材5の粘着層 6と剥離紙1の剥離層4との間で容易に剥離し、剥離後において、剥離紙1が、 基紙2と合成樹脂ラミネート層3との間で、容易に剥離・分断できる。 According to the release paper of the present invention, the base paper 2, the synthetic resin laminate layer 3 laminated on the base paper 2 so as to be in a temporarily attached state, and the silicone coat applied on the synthetic resin laminate layer 3 are used. The adhesive layer 6 of the base material 5 is composed of the release layer 4 and the base paper 2 and the synthetic resin laminate layer 3 are bonded in a temporary attachment state via the release layer. Since the adhesive strength between the release paper 1 and the release layer 4 of the release paper 1 is made larger, the adhesive layer 6 of the base substrate 5 and the release layer of the release paper 1 are used when the release paper 1 is peeled from the base substrate 5 during use. 4, the release paper 1 can be easily peeled and divided between the base paper 2 and the synthetic resin laminate layer 3 after the peeling.

【0015】 従って、ベース基材より剥離後の剥離紙が、その合成樹脂ラミネート層と基紙 とが容易に剥離分断可能であり、両部材がそれぞれ回収・再生(リサイクル)可 能な剥離紙を提供でき、資源の有効利用、廃棄公害防止ならびに昨今問題となっ ている地球環境保護などの面からも極めて優れた考案である。Therefore, the release paper after peeling from the base material can be easily separated and separated between the synthetic resin laminate layer and the base paper, and both members can be collected and recycled (recyclable). It is an excellent idea from the perspective of being able to provide, effective use of resources, prevention of waste pollution, and protection of the global environment, which has become a problem in recent years.
