The present invention relates to a self-adhesive laminated film useful as a packaging material for ensuring waterproofing, antifouling or safety.
携帯電話、携帯型ゲーム機、カメラ等の各種の小型機器を、例えば、海浜、プール、スキー／スケート場等の場所で使用すると、小型機器が濡れて故障する恐れがある。また、そのような環境下においては、機器が濡れないように通常は鞄や袋等に入れておき、使用する時だけ取り出すのが一般的であるが、使用の都度取り出すのは極めて不便である。 When various small devices such as a mobile phone, a portable game machine, and a camera are used in places such as a beach, a pool, and a ski / skate rink, the small devices may get wet and break down. Also, in such an environment, it is common to place the device in a bag or bag so that the device does not get wet, and to remove it only when it is used, but it is extremely inconvenient to take it out each time it is used. .
また、刃や突起を有する物は、通常、その物を使用しない時は専用の入れ物等に入れておくのが一般的であるが、物の種類に拠らず簡易に安全性を確保できる方法があれば便利である。 In addition, it is common for items with blades or protrusions to be placed in a dedicated container when the item is not used, but a method that can ensure safety easily regardless of the type of item. If there is, it is convenient.

The self-adhesive laminated film is characterized in that it is 2.0 N / cm or more, and an inclined ball tack value (JIS Z 0237.14) of the adhesive layer is 3 or less within the temperature range.
さらに本発明は、上記自己接着積層フィルムから成り、被包装体の表面の全面又は一部の面を被覆して接着材層面同士を圧着することにより、前記被包装体の防水、防汚又は安全性を確保する為に用いる包装用フィルム；並びに、上記自己接着積層フィルムを用い、被包装体の表面の全面又は一部の面を被覆して圧着性接着材層面同士を０〜５０℃の温度範囲にて圧着する包装方法である。 Furthermore, the present invention comprises the above self-adhesive laminated film, covers the entire surface or a part of the surface of the packaged body, and presses the adhesive layer surfaces together, thereby waterproofing, antifouling or safety of the packaged body.

Moreover, it is preferable to have sufficient transparency and flexibility so that keys and buttons can be operated from above the film in a state where devices such as a calculator and a mobile phone are packaged. From these points, the visible light transmittance of the base film is preferably 70% or more, the tensile elastic modulus of the base film is preferably 1000 MPa or less, and the thickness of the base film is preferably 10 to 100 μm.

When the user uses this for packaging an article, the surfaces of the pressure-sensitive adhesive layer are pressure-bonded at room temperature. Accordingly, it is preferable that the base film and the pressure-sensitive adhesive layer have different color designs so that the surface to be pressure-bonded can be easily recognized. If necessary, an intermediate layer may be provided between the base film and the pressure-sensitive adhesive layer. This intermediate layer plays a role of, for example, transparency, impact buffering, adhesion support between the base film and the pressure-sensitive adhesive layer, light refractive index adjustment, tensile elongation adjustment, hue, antireflection, and the like.
図１は、本発明の自己接着性積層フィルムを用いて被包装体の全体を包装する状態を例示する模式的断面図である。この図においては、被包装体２の上下の面を二枚の自己接着性積層フィルム１（包装用フィルム）で覆い、各フィルム１の両端の圧着性接着材層面同士を圧着することにより全体を包装している。このフィルムの圧着にはホットシール等の装置や熱源を必要とせず、使用する場所において常温（０〜５０℃）で、瞬時に、かつ簡易に圧着でき、完全な密封を達成できるので非常に便利である。
FIG. 1 is a schematic cross-sectional view illustrating a state in which the entire packaged body is packaged using the self-adhesive laminated film of the present invention. In this figure, the upper and lower surfaces of the
図２は、本発明の自己接着性積層フィルムを用いて多数の被包装体を包装する状態を例示する模式的断面図である。この図においては、一枚の自己接着性積層フィルム１（包装用フィルム）を用いて多数の被包装体３をまとめて覆い、そのフィルム１の両端の圧着性接着材層面同士を圧着することにより包装している。この図に示すように、本発明において被包装体は一つに限定されず、複数の被包装体をまとめて包装することも可能であり、また、一度の包装に用いる自己接着性積層フィルム１は、複数枚でも一枚でもよい。
FIG. 2 is a schematic cross-sectional view illustrating a state in which a large number of packages are packaged using the self-adhesive laminated film of the present invention. In this figure, a single self-adhesive laminated film 1 (wrapping film) is used to cover a large number of
図１及び図２示したように、本発明の自己接着性積層フィルムを用いて包装する場合においては、圧着性接着材層面同士の自着力が−１０℃〜８０℃の温度範囲内において２.０Ｎ／ｃｍ以上なので、ホットシール等の装置や熱源を必要とせず、使用する場所において単に圧着性接着材層面同士を常温（０〜５０℃）で手で圧着することにより、その圧着部分が強く接着して剥離せず、不可剥離的に強く包装でき、小型機器等の被包装体の防水や防汚を簡易に実現でき、例えば、海辺での携帯電話等の小型機器の使用を可能にしたり、水分、オイル、ダスト等から小型機器を完全に保護する点で非常に有用である。また、圧着性接着材層の傾斜式ボールタック値（ＪＩＳ Ｚ ０２３７.１４）が前記温度範囲内において３以下なので、剥離後に被包装体の表面に糊残りが生じない。しかも、包装した状態でその小型機器の計器類や情報パネル等を透視することも可能であり、フィルムの上からキーやボタンを操作することも可能となり非常に便利である。さらに刃や突起を有する物の場合は、物の種類に拠らず包装でき、人体を切傷から保護するなど安全性を簡易に確保できる。 As shown in FIGS. 1 and 2, when packaging with the self-adhesive laminated film of the present invention, the self-adhesive strength between the pressure-sensitive adhesive layer surfaces is within a temperature range of −10 ° C. to 80 ° C. Since it is 0 N / cm or more, there is no need for an apparatus such as a hot seal or a heat source, and the pressure-bonding part is strongly bonded by simply crimping the pressure-sensitive adhesive layer surfaces by hand at room temperature (0 to 50 ° C.). It can be strongly peeled and peeled off without being peeled off, and it can easily realize waterproofing and antifouling of a packaged object such as a small device. For example, it enables use of a small device such as a mobile phone at the seaside. It is very useful in that it completely protects small equipment from moisture, oil, dust and the like. Further, since the slanting ball tack value (JIS Z 0237.14) of the pressure-sensitive adhesive layer is 3 or less within the above temperature range, no adhesive residue is generated on the surface of the packaged body after peeling. Moreover, it is possible to see through the instruments, information panels, etc. of the small equipment in a packaged state, and it is possible to operate keys and buttons from the top of the film, which is very convenient. Furthermore, in the case of an object having a blade or a protrusion, it can be packaged regardless of the kind of the object, and safety can be easily ensured by protecting the human body from cuts.
本発明は、携帯電話、卓上小型計算機、情報表示装置、刃又は突起を有する物等の包装の用途に非常に有用であるが、本発明はこれに限定されない。例えば、携帯電話、携帯ラジオ、ヘッドフォーンステレオ、ラジオカセット、トランスシーバ等の通信・オーディオ機器；小型電子計算機、レジスター、キーボード、電子手帳、携帯パソコン、ゲーム機、ＰＤＡ（携帯型情報端末）等の携帯電子機器；時計、圧力計、ゲージ等の精密機械・精密機器；カメラ及びカメラ部品、ビデオカメラ、監視カメラ、レンズ、フィルター、ミラー、発光体、プリズム、顕微鏡、タッチパネル等の光学機器・部品・文字盤；携帯型ゲーム機、身体測定器及びそれらのパネル、カバー等の玩具・スポーツ用品・健康器具；刃物、包丁、鋏、鋸、チェーンソウ、カッター、ドリル、ピンセット、爪切り、ピン、ビス、機械類の歯、針等の刃物工具・器具；板ガラス、合成樹脂ガラス等の硝子・ガラス製品；油脂、チーズ等の電磁波調理用・冷凍品保存食品；コンパス、定規、ピン、針等の文具；などの包装用途にも使用可能である。 The present invention is very useful for applications such as cellular phones, desktop small computers, information display devices, and objects having blades or protrusions, but the present invention is not limited thereto. For example, communication / audio devices such as mobile phones, portable radios, headphone stereos, radio cassettes, and transceivers; small electronic computers, registers, keyboards, electronic notebooks, portable personal computers, game machines, PDAs (portable information terminals), etc. Portable electronic equipment: Precision machines and precision equipment such as watches, pressure gauges, gauges, etc .; Optical equipment and parts such as cameras and camera parts, video cameras, surveillance cameras, lenses, filters, mirrors, light emitters, prisms, microscopes, touch panels, etc. Dial; portable game machines, body measuring instruments and their toys, sports equipment and health equipment such as panels and covers; blades, knives, scissors, saws, chainsaws, cutters, drills, tweezers, nail clippers, pins, screws Cutting tools and instruments such as machinery teeth and needles; Glass and glass products such as plate glass and synthetic resin glass; Electromagnetic cooking and frozen goods store foods such as cheese; compass, ruler, pins, needles, such as stationery; can also be used in packaging applications, such as.
