Description
本発明は、基材と粘着剤層、場合によってはさらに剥離ライナーが積層された帯状貼付材をロール状に巻回してなる貼付材巻回体を、包装材によって被覆された包装構造に関する。 TECHNICAL FIELD The present invention relates to a packaging structure in which a wound adhesive material obtained by winding a belt-like adhesive material in which a base material and an adhesive layer, and optionally a release liner are further laminated, in a roll shape is covered with the packaging material.
従来から医療衛生分野およびスポーツ分野等において用いられる貼付材は、人の皮膚に貼り付けられ、または巻き付けられることにより、対象部位の治療や怪我の予防等に効果を発揮するものである。帯状の形態を有する貼付材は、ロール状に巻回された貼付材巻回体として知られている。 Conventionally, adhesive materials used in the medical hygiene field, sports field, and the like are effective in treating a target site and preventing injury by being affixed or wound around a human skin. A patch having a belt-like shape is known as a wound patch wound in a roll shape.
貼付材巻回体は、使用するまでの間、解けたり、或いは、ゴミの付着を防止するために、通常、包装材によって被覆された包装構造として広く普及している。そして、使用時に包装された貼付材巻回体を取り出すためには、包装材を簡便に開封できることが望ましい。 In order to prevent the sticking material wound body from being unwound or adhering to dust until it is used, it is generally widely used as a packaging structure covered with a packaging material. And in order to take out the winding material wound body packaged at the time of use, it is desirable that a packaging material can be opened simply.
包装材を開封し易くするために、例えば、フィルムの長手方向の一端側を巻芯側としてロール状に巻回したロール状フィルムの全体を包装するロール状フィルムの包装材において、ロール状フィルムの全体を包装する包装材の軸方向の全長に亘って帯状の切断テープを設けるとともに、この切断テープの両サイドにおける包装材に切断テープの全長に亘ってミシン目を設けることが開示されている（特許文献１参照）。包装材の端部における切断テープを手指で摘まんで引き上げることにより、切断テープがミシン目に沿ってロール状フィルムの軸方向に沿って引き裂かれて包装材が開封されるものである。
しかし、切断テープをミシン目に沿ってロール状フィルムの軸方向に沿って引き裂くことによって取り出し口が形成されるが、その取り出し口は小さいため、包装材の材質や厚みによっては包装材が変形しにくく、依然として中のロール状フィルムを取り出しにくいものであった。
In order to make it easy to open the packaging material, for example, in the packaging material of the roll-shaped film that wraps the entire roll-shaped film wound in a roll shape with one end side in the longitudinal direction of the film as the core side, It is disclosed that a strip-shaped cutting tape is provided over the entire length in the axial direction of the packaging material for packaging the whole, and a perforation is provided in the packaging material on both sides of the cutting tape over the entire length of the cutting tape. Patent Document 1). When the cutting tape at the end of the packaging material is picked up by a finger and pulled up, the cutting tape is torn along the axial direction of the roll film along the perforation, and the packaging material is opened.
However, although the takeout opening is formed by tearing the cutting tape along the perforated line along the axial direction of the roll film, the takeout opening is small, so the packaging material may be deformed depending on the material and thickness of the packaging material. It was difficult to take out the roll film inside.
また、熱収縮性フィルムにて被覆された包装品を取り出し易くするために、熱収縮性フィルムに種々の切り取り線を設けることが開示されている（特許文献２参照）。しかしながら、前記切り取り線が設けられた熱収縮性フィルムを開封するためには、包装品の側面を下にして置いた状態で熱収縮性フィルムを開封する必要があり、包装品を手に持った状態で、包装された熱収縮性フィルムを開封し、簡便に中の製品を取り出すことは難しいものであった。 Moreover, in order to make it easy to take out a package covered with a heat-shrinkable film, it has been disclosed to provide various cut lines on the heat-shrinkable film (see Patent Document 2). However, in order to open the heat-shrinkable film provided with the cut line, it is necessary to open the heat-shrinkable film with the side face of the packaged product facing down. In the state, it was difficult to open the packaged heat-shrinkable film and easily take out the product inside.
本発明は、このような事情に鑑みてなされたものであり、貼付材巻回体の外周面および両側面を包装材によって被覆された包装構造に関するものであって、包装材を簡便に開封することができるとともに、包装材を容易に外側へ開くことができるので、包装材によって被覆された貼付材巻回体を簡便に取り出すことができる包装構造を提供する。 The present invention has been made in view of such circumstances, and relates to a packaging structure in which the outer peripheral surface and both side surfaces of a wound wound adhesive material are covered with a packaging material, and the packaging material is simply opened. In addition, since the packaging material can be easily opened to the outside, a packaging structure in which the wound wound adhesive material covered with the packaging material can be easily taken out is provided.
本発明は、上記の課題を解決するために鋭意検討して見出したものであり、下記に示すとおりである。

包装材に形成された２本の第１弱化線を切断することにより切り取り部が形成され、包装材を簡単に開封することができる。また、包装材には第２弱化線を有することにより、第２弱化線を支点として熱収縮性フィルムを外側に大きく開き、広い取り出し口を確保することができるので、収納していた貼付材巻回体を簡便に取り出すことができる。 By cutting the two first weakening lines formed in the packaging material, a cut-out portion is formed, and the packaging material can be easily opened. In addition, since the packaging material has the second weakening line, the heat-shrinkable film can be opened to the outside with the second weakening line as a fulcrum, and a wide outlet can be secured. The round body can be easily taken out.
本発明の包装構造は、帯状貼付材をロール状に巻回した貼付材巻回体の外周面および両側面を、包装材によって被覆したものである。 In the packaging structure of the present invention, the outer peripheral surface and both side surfaces of a wound patch wound body obtained by winding a belt-shaped patch in a roll shape are covered with the packaging material.
本発明の包装構造を構成する包装材には、被覆している包装材を開封し、中の貼付材巻回体を簡便に取り出し易くするために、貼付材巻回体の外周面に接する面の周方向に対して略直交し、端縁部に至る、２本の第１弱化線によって構成される切り取り部を有することが特徴である。前記端縁部には、摘み部を備えていることが好ましく、被覆している包装材を開封する際には、この摘み部を引張り、第１弱化線に沿って切断することにより切り取り部が形成され、包装材を簡便に開封することが可能になる。なお、包装材を開封する際に、切り取り部が途中で短く切断してしまうことを防止するために、切り取り部には第１弱化線に沿って補強用フィルムが積層していてもよい。 In the packaging material constituting the packaging structure of the present invention, the surface that is in contact with the outer peripheral surface of the adhesive material wound body in order to open the covered packaging material and easily take out the wound adhesive material wound body. It is characterized by having a cut-out part constituted by two first weakening lines that are substantially orthogonal to the circumferential direction of the first and second ends and reach the edge. It is preferable that the edge portion is provided with a knob, and when opening the covering packaging material, the knob is pulled and cut along the first weakening line so that the cut-out portion is formed. Thus, the packaging material can be easily opened. In addition, when opening a packaging material, in order to prevent that a cut part cut | disconnects short in the middle, the reinforcing film may be laminated | stacked on the cut part along the 1st weakening line.
そして、包装材には、切り取り部から、周方向に一定の距離を隔てた位置に、貼付材巻回体の外周面に接する面の周方向に対して略直交し、端縁部に至る第２弱化線を有することが特徴である。前記摘み部をきっかけにして切り取り部を取り去り、包装材を開封した後、図３に示すように、第２弱化線を支点に包装材を外側へ開くことができるので、広い取り出し口を確保することができ、収納している貼付材巻回体を容易に取り出すことができる。なお、包装材を開封し外側へ開く際には、例えば、図３に示すように、貼付材巻回体の両側面に位置する第２弱化線は切断され、貼付材巻回体の外周面に位置する第２弱化線は切断されずに包装材を折り返す部分として機能しても良い。 Then, the packaging material is provided at a position spaced apart from the cut portion by a certain distance in the circumferential direction, substantially perpendicular to the circumferential direction of the surface in contact with the outer circumferential surface of the adhesive wound body, and reaching the edge portion. It is characterized by having 2 weakening lines. After removing the cut-out portion using the knob as a trigger and opening the packaging material, as shown in FIG. 3, the packaging material can be opened to the outside with the second weakening line as a fulcrum, thus ensuring a wide outlet. It is possible to easily take out the wound wound wound adhesive material. When the packaging material is opened and opened to the outside, for example, as shown in FIG. 3, the second weakening lines located on both side surfaces of the adhesive material wound body are cut, and the outer peripheral surface of the adhesive material wound body The 2nd weakening line located in may not be cut | disconnected, but may function as a part which wraps a packaging material.
大きな取り出し口を確保することができ、かつ、包装材を外側へ開く際に手や指で持つためのスペースを確保するために、第２弱化線は、切り取り部から、周方向に１／８周長〜１／２周長隔てた位置に形成することが好ましく、１／６周長〜１／３周長隔てた位置に形成することがより好ましい。第２弱化線を、切り取り部から、周方向に１／８周長未満の位置に形成すると、包装材を開封し外側へ開いても、取り出し口が小さいため中の貼付材巻回体を取り出しにくい。 In order to secure a large take-out opening and to secure a space for holding the packaging material with a hand or a finger when opening the packaging material outward, the second weakening line is 1/8 in the circumferential direction from the cutout portion. It is preferable to form at a position separated by a circumferential length to 1/2 circumferential length, and more preferably at a position separated by 1/6 circumferential length to 1/3 circumferential length. If the second weakening line is formed at a position less than 1/8 circumferential length in the circumferential direction from the cut-out part, even if the packaging material is opened and opened to the outside, the takeout wound body is taken out because the outlet is small Hateful.
さらに、大きな取り出し口を確保するために、図４に示すように、切り取り部を基準に、第２弱化線とは反対側の、切り取り部から周方向に隔てた位置に、貼付材巻回体の外周面に接する面の周方向に対して略直交し、端縁部に至る第３弱化線を形成しても良い。
第２弱化線に加えて第３弱化線を設ける場合、第２弱化線および第３弱化線が、それぞれ切り取り部から周方向に１／１６周長〜１／３周長隔てた位置に形成することが好ましく、１／１２周長〜１／４周長隔てた位置に形成することがより好ましい。第２弱化線と第３弱化線を設ける場合、第２弱化線および第３弱化線を、切り取り部から、周方向に１／１６周長未満の位置に形成すると、包装材を開封し外側へ開いても、取り出し口が小さいため中の貼付材巻回体を取り出しにくい。一方、第２弱化線および第３弱化線を、切り取り部から、周方向に１／３周長を超える位置に形成すると、包装材を開封後外側へ開く際に、手や指で持つための十分なスペースを確保することができない。
Furthermore, in order to secure a large take-out port, as shown in FIG. 4, the wound adhesive wound body is positioned on the opposite side of the second weakening line from the cut-out portion in the circumferential direction as shown in FIG. A third weakening line that is substantially orthogonal to the circumferential direction of the surface in contact with the outer peripheral surface and reaches the end edge portion may be formed.
When providing the 3rd weakening line in addition to the 2nd weakening line, the 2nd weakening line and the 3rd weakening line are formed in the position spaced apart from the 1/16 circumference to the 1/3 circumference in the circumferential direction from the cut part, respectively. It is more preferable to form it at a position separated by 1/12 circumferential length to 1/4 circumferential length. When providing the 2nd weakening line and the 3rd weakening line, if the 2nd weakening line and the 3rd weakening line are formed in the position less than 1/16 circumference length from the cutout part in the peripheral direction, the packaging material will be opened and outside Even if it is opened, it is difficult to take out the wound wound adhesive material because the outlet is small. On the other hand, when the second weakening line and the third weakening line are formed at a position exceeding the 1/3 circumference in the circumferential direction from the cut portion, when opening the packaging material to the outside after opening, it is for holding with hands and fingers Sufficient space cannot be secured.

In the method of forming the first weakened line, the second weakened line, and the third weakened line after the packaging material is covered with the packaging material wound body, not only the coated packaging material but also the middle packaging material winding This is not preferable because the body may be cut.
本発明に用いられる包装材は、貼付材巻回体の形状に密着しコンパクトに包装することができる点で熱収縮性フィルムが好ましい。
熱収縮性フィルムの素材としては、２５℃以上の温度で収縮性を有するフィルムであれば特に限定されないが、例えば、ポリオレフィン系フィルム、ポリエステル系フィルム、ポリスチレン系フィルム、ポリ乳酸系フィルム、ポリ塩化ビニル系フィルム、ポリアミド系フィルム、およびその誘導体などが用いられる。中でも、焼却時に塩素系ガスの発生のおそれがないポリオレフィン系フィルム、ポリエステル系フィルム、ポリ乳酸系フィルムを用いることが好ましく、中でもポリプロピレン系フィルムやポリ乳酸系フィルムは、比較的透明性や光沢が良好で、他の材料からなる熱収縮性フィルムと比較して耐熱性、力学的強度に優れている。なお、これらのフィルムは、フィルム形成時に１軸ないし２軸延伸処理を行ったものが好ましい。熱収縮性フィルムを構成する樹脂組成物には、本発明の特徴を損なわない程度で他のポリマーを含有させてもよい。
The packaging material used in the present invention is preferably a heat-shrinkable film in that it can adhere to the shape of the patch wound body and can be packaged compactly.
The material of the heat-shrinkable film is not particularly limited as long as it is a film that has shrinkability at a temperature of 25 ° C. or more. For example, polyolefin film, polyester film, polystyrene film, polylactic acid film, polyvinyl chloride Films, polyamide films, and derivatives thereof are used. Among them, it is preferable to use a polyolefin-based film, a polyester-based film, or a polylactic acid-based film that does not cause the generation of chlorine-based gas during incineration. Among them, a polypropylene-based film or a polylactic acid-based film has relatively good transparency and gloss. Thus, it is excellent in heat resistance and mechanical strength as compared with heat-shrinkable films made of other materials. These films are preferably those subjected to uniaxial or biaxial stretching during film formation. You may make the resin composition which comprises a heat-shrinkable film contain another polymer to such an extent that the characteristic of this invention is not impaired.
熱収縮性フィルムは、単層構造のフィルムでも、複層構造のフィルムでもよい。また、熱収縮性フィルムには、本発明の効果に影響を及ぼさない範囲で、金属蒸着層などの機能層を設けたり、粘着付与樹脂、軟化剤、無機フィラーや、必要に応じて他の添加剤、例えば、熱安定剤、光安定剤、紫外線吸収剤、酸化防止剤、滑剤、着色剤、帯電防止剤、難燃剤、撥水剤、防水剤、親水性付与剤、防菌剤などを含有していてもよい。 The heat-shrinkable film may be a single layer structure film or a multilayer structure film. In addition, the heat-shrinkable film is provided with a functional layer such as a metal vapor-deposited layer as long as it does not affect the effects of the present invention, or a tackifier resin, a softener, an inorganic filler, or other additives as necessary. Contains agents such as heat stabilizers, light stabilizers, UV absorbers, antioxidants, lubricants, colorants, antistatic agents, flame retardants, water repellents, waterproofing agents, hydrophilicity-imparting agents, antibacterial agents, etc. You may do it.
包装材の厚みとしては、好ましくは２０μｍ〜１００μｍであり、より好ましくは３０μｍ〜５０μｍである。包装材の厚みが２０μｍ〜１００μｍの範囲であれば、適度なフィルム強度が得られるので好適である。なお、包装材が熱収縮性フィルムの場合には、その厚みが２０μｍ〜１００μｍの範囲であれば、適度なフィルム強度が得られるだけでなく、良好な収縮特性も得られるので好適である。
本発明に用いられる包装材は、中の貼付材巻回体を目視で確認することができるように、透明もしくは半透明であることが好ましい。
The thickness of the packaging material is preferably 20 μm to 100 μm, more preferably 30 μm to 50 μm. If the thickness of the packaging material is in the range of 20 μm to 100 μm, an appropriate film strength can be obtained, which is preferable. In addition, when the packaging material is a heat-shrinkable film, if the thickness is in the range of 20 μm to 100 μm, it is preferable because not only an appropriate film strength can be obtained but also a good shrinkage characteristic can be obtained.
It is preferable that the packaging material used in the present invention is transparent or translucent so that the wound adhesive material wound body can be visually confirmed.
熱収縮性フィルムの収縮率としては、加熱温度が１１５℃、加熱時間が１０秒の場合、３０％〜７０％が好ましく、４０％〜６０％がより好ましい。
なお、収縮率は次式により算出した値である。
収縮率（％）＝（Ｌ０−Ｌ）／Ｌ０×１００（Ｌ０：収縮前の長さ、Ｌ：収縮後の長さ）
熱収縮性フィルムの収縮率が３０％未満の場合、収縮特性が悪いため包装工程において、長時間加熱する必要があり、包装工程の処理能力が低下するため好ましくなく、７０％を超えるとフィルムが収縮しすぎるため、安定的に品質良好な包装構造を得ることができないため、好ましくない。
The shrinkage ratio of the heat-shrinkable film is preferably 30% to 70%, more preferably 40% to 60% when the heating temperature is 115 ° C. and the heating time is 10 seconds.
The shrinkage rate is a value calculated by the following equation.
Shrinkage rate (%) = (L 0 −L) / L 0 × 100 (L 0 : length before shrinkage, L: length after shrinkage)
When the shrinkage rate of the heat-shrinkable film is less than 30%, the shrinkage characteristics are poor, so it is necessary to heat for a long time in the packaging process, and the processing capability of the packaging process is reduced. Since it shrinks too much, a packaging structure with good quality cannot be obtained stably, which is not preferable.
貼付材を構成する基材は、様々な用途に用いられている一般的な基材を使用することができる。構造に関しては、織布、不織布、編布、紙などの繊維の集合体類、および多孔シート、通気性シートなどのシート状物などが例示される。また、材料に関しては、ナイロン、ポリエステル、ポリエチレン、ポリプロピレン、ポリウレタン、セルロースなどの合成あるいは天然の有機高分子類が例示される。 As the base material constituting the patch, general base materials used for various purposes can be used.

Examples of the material include synthetic or natural organic polymers such as nylon, polyester, polyethylene, polypropylene, polyurethane, and cellulose.
特に、医療衛生分野およびスポーツ分野などの貼付材のように皮膚を被着体とする場合には、通気性もしくは透湿性を有し、かつ、防水性を有するものが好適に使用される。このような基材としては、水の接触角が大きくて水に濡れ難い材料からなる多孔シート、或いは水に濡れ易い材料からなる多孔シート、それを撥水処理したもの、などが挙げられる。水に濡れ難い材料の多孔シートとしては、例えば、ポリエチレン、ポリプロピレン、ポリブテン、エチレン−プロピレン共重合体、エチレン−酢酸ビニル共重合体、エチレン−エチルアクリレート共重合体などのポリオレフィン類、或いはポリウレタン、ポリエステル、ポリアミドなどのその他のプラスチック類などの有機高分子からなる穿孔フィルム、連続気泡を有する発泡シート、織物、不織布、編物、紙などが挙げられる。水に濡れ易い材料からなる多孔シートとしては、木綿、セルロース、ポリビニルアルコールなどの有機高分子類からなる織物、不織布、編物、紙、ポリビニルアルコールの穿孔フィルムなどが挙げられる。水に濡れ易い材料からなる多孔シートは、粘着剤層未形成面に一般的に知られている撥水剤にて撥水処理して使用される。なお、上記の水に濡れ難い材料の多孔シートも必要に応じて撥水処理して使用される。基材は、非伸縮性であっても良く、また縦方向および／または横方向に伸縮性を有するものであっても良い。 In particular, when the skin is used as an adherend, such as a patch in the medical hygiene field and sports field, a material having air permeability or moisture permeability and waterproof is preferably used. Examples of such a substrate include a porous sheet made of a material that has a large contact angle with water and hardly wets with water, a porous sheet made of a material that easily gets wet with water, and a water-repellent treated product thereof. Examples of porous sheets made of materials that are difficult to wet with water include polyolefins such as polyethylene, polypropylene, polybutene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, polyurethane, and polyester. And a perforated film made of an organic polymer such as other plastics such as polyamide, a foam sheet having open cells, a woven fabric, a nonwoven fabric, a knitted fabric, and paper. Examples of the porous sheet made of a material that easily gets wet with water include woven fabrics, nonwoven fabrics, knitted fabrics, paper, and perforated films of polyvinyl alcohol made of organic polymers such as cotton, cellulose, and polyvinyl alcohol. A porous sheet made of a material that easily wets water is used after being subjected to water repellent treatment with a generally known water repellent on the surface where the pressure-sensitive adhesive layer is not formed. In addition, the porous sheet of the material which does not easily get wet with water is used after being subjected to water repellent treatment as necessary. The base material may be non-stretchable, and may be stretchable in the vertical direction and / or the horizontal direction.
基材の厚みは、材質、用途などによって適宜、決定することが好ましいが、通常、フィルムを基材とする場合には、１０μｍ〜２５０μｍが好ましく、１０μｍ〜１００μｍがさらに好ましい。また、織布や不織布などの布帛や紙などを基材とする場合には、５０μｍ〜５００μｍが好ましく、１００μｍ〜３００μｍがさらに好ましい。なお、後者のような布帛、紙などを基材に用いる場合には、絶対厚みを測定することが困難な場合もあるので、坪量が８ｇ／ｍ２〜２００ｇ／ｍ２のものを用いることが好適である。 The thickness of the base material is preferably determined as appropriate depending on the material, use, etc., but usually 10 μm to 250 μm is preferable and 10 μm to 100 μm is more preferable when a film is used as the base material. Moreover, when using as a base material fabrics, such as a woven fabric and a nonwoven fabric, and paper, 50 micrometers-500 micrometers are preferable, and 100 micrometers-300 micrometers are more preferable. Incidentally, the fabric as the latter, in the case of using such to the substrate paper, so that measuring the absolute thickness is sometimes difficult, the basis weight used ones 8g / m 2 ~200g / m 2 Is preferred.
貼付材に用いられる粘着剤層を構成する粘着剤は、一般的に用いられているものを用途に応じて適宜使用することができる。具体的には、天然ゴム系粘着剤、合成ゴム系粘着剤、アクリル系粘着剤、シリコーン系粘着剤、ビニルエーテル系粘着剤、ビニルエステル系粘着剤、ポリエステル系粘着剤、ウレタン系粘着剤などの粘着剤を用いることができ、これらは単独でまたは複数以上組み合わせて使用される。また、医療衛生分野およびスポーツ分野などの貼付材において使用される場合には、被着体である皮膚に対して刺激が少ない材料が好適に使用される。 As the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer used for the patch, a generally used pressure-sensitive adhesive can be appropriately used depending on the application. Specifically, natural rubber adhesives, synthetic rubber adhesives, acrylic adhesives, silicone adhesives, vinyl ether adhesives, vinyl ester adhesives, polyester adhesives, urethane adhesives, etc. An agent can be used, and these are used alone or in combination of two or more. In addition, when used in a patch material in the medical hygiene field and sports field, a material that is less irritating to the skin as the adherend is preferably used.
粘着剤層の厚みは、使用部位や粘着剤の種類によって適宜決定することができるが、１０μｍ〜３００μｍが好ましく、２０μｍ〜２００μｍがより好ましい。粘着剤層の厚みが１０μｍ未満だと被着体との粘着力不足により貼付中に貼付材が剥がれるおそれがある。一方、粘着剤層の厚みが３００μｍを超えると貼付材の端縁部から粘着剤がはみ出して糊汚れが生じる可能性がある。 Although the thickness of an adhesive layer can be suitably determined with the use site | part and the kind of adhesive, 10 micrometers-300 micrometers are preferable and 20 micrometers-200 micrometers are more preferable. If the thickness of the pressure-sensitive adhesive layer is less than 10 μm, the adhesive material may be peeled off during application due to insufficient adhesion with the adherend. On the other hand, when the thickness of the pressure-sensitive adhesive layer exceeds 300 μm, the pressure-sensitive adhesive protrudes from the edge of the patch, and there is a possibility that glue stains will occur.
貼付材に用いられる剥離ライナーは一般的に使用されるものを適用することができるが、経済性を考慮すると紙製の剥離ライナーを用いることが好ましい。紙製の剥離ライナーとしては、例えば、上質紙、グラシン紙、パーチメント紙の表面に、シリコーン樹脂やフッ素樹脂などの剥離性能を有する剥離剤をコーティングしたものなどが挙げられる。 Although generally used release liners can be applied to the patch, it is preferable to use a paper release liner in consideration of economy. Examples of the paper release liner include those obtained by coating the surface of high-quality paper, glassine paper, and parchment paper with a release agent having release performance such as silicone resin or fluororesin.
本発明の包装構造は、例えば、図７（ａ）の貼付材巻回体に、図７（ｂ）のような所定の長さに切断した円筒状の熱収縮性フィルムを、図７（ｃ）に示すように円筒状の前記熱収縮性フィルムの円筒部が、貼付材巻回体の外周面に対面するように貼付材巻回体に被せる。そして、熱収縮性フィルムを被せた貼付材巻回体を加熱することにより、前記熱収縮性フィルムが収縮し、貼付材巻回体の形状に密着することで、図７（ｄ）に示すような本発明の包装構造を得ることができる。 In the packaging structure of the present invention, for example, a cylindrical heat-shrinkable film cut into a predetermined length as shown in FIG. ), The cylindrical portion of the cylindrical heat-shrinkable film is placed on the wound adhesive wound body so as to face the outer peripheral surface of the adhesive wound body. And as shown in FIG.7 (d), the said heat-shrinkable film shrink | contracts by heating the adhesive material winding body which covered the heat-shrinkable film, and it closely_contact | adheres to the shape of an adhesive material winding body. A packaging structure according to the present invention can be obtained.
貼付材巻回体を被覆した熱収縮性フィルムを加熱する温度としては、熱収縮性フィルムの材質などによって適宜設定される。熱収縮性フィルムがポリプロピレン系フィルムやポリ乳酸系フィルムの場合、加熱温度は、８０℃〜１４０℃が好ましく、９５℃〜１２５℃がより好ましい。加熱温度が８０℃未満だと、収縮特性が悪いため包装工程において、長時間加熱する必要があり、包装工程の処理能力が低下するため好ましくなく、１４０℃を超えるとフィルムが収縮しすぎるため、安定的に品質良好な包装構造を得ることができないため、好ましくない。
また、加熱時間としては、出来るだけ短く、かつ、安定な収縮特性を得るために、５秒〜３０秒が好ましく、１０秒〜２０秒がより好ましい。加熱時間が５秒未満だと、フィルムに十分な収縮特性を発現できないし、加熱時間が３０秒を超えると、フィルムが収縮しすぎるため、安定的に品質良好な包装構造を得ることができないため、好ましくない。
The temperature for heating the heat-shrinkable film covering the patch wound body is appropriately set depending on the material of the heat-shrinkable film. When the heat-shrinkable film is a polypropylene film or a polylactic acid film, the heating temperature is preferably 80 ° C to 140 ° C, more preferably 95 ° C to 125 ° C. If the heating temperature is less than 80 ° C, the shrinkage characteristics are poor, so it is necessary to heat for a long time in the packaging process, which is not preferable because the processing capacity of the packaging process is reduced, and if it exceeds 140 ° C, the film will shrink too much, This is not preferable because it is impossible to stably obtain a packaging structure with good quality.
Further, the heating time is preferably as short as possible and 5 seconds to 30 seconds, and more preferably 10 seconds to 20 seconds in order to obtain stable shrinkage characteristics. If the heating time is less than 5 seconds, sufficient shrinkage characteristics cannot be expressed on the film, and if the heating time exceeds 30 seconds, the film will shrink too much, so a stable and good quality packaging structure cannot be obtained. It is not preferable.
