Description

【0001】
【発明の属する技術分野】
本発明は、紙基材の優れた緩衝作用を有し、廃棄処理が容易で、汎用性、作業性、経済性を兼ねそえた緩衝包装部材に関する。
【0002】
【従来の技術】
工業用部品あるいは機器、治具、または引越し時における茶碗、皿、装飾品、電化製品等を輸送するときに、これらの輸送物の破損、傷付き等を防止する為に包装あるいは梱包が行われる。
【0003】
このような従来の包装あるいは梱包技術としては、工業部品や治具、工具、付属部品、計測機器類等においては、予めその輸送物の構造、形状、材質、輸送方法等に応じて、クッション材や木箱、ダンボール箱等を利用して梱包包装が行われている。
【0004】
また、洗濯機や冷蔵庫等の大型家電製品を輸送する場合には予め輸送物が衝撃、落下、振動、圧縮等に対して安全率を考慮して輸送包装設計が行われている。
【0005】
輸送包装設計は輸送物、輸送先、輸送方法等に応じて木構造の設計、紙器、段ボール等の設計、緩衝設計、防錆・防湿等の検討のほか固定法、封緘、結束等の包装技法を実施し、包装構造、部材、構成等が決定されている。
【0006】
輸送包装設計の結果、洗濯機や冷蔵庫等の大型家電製品を輸送する場合には、輸送する洗濯機や冷蔵庫等の少なくても上下四隅にその形状に対応するように成形されたパルプモールドあるいは発泡塩化ビニールフォーム、ウレタンまたは発泡スチロール等の緩衝材を当て、段ボール設計された所定のライナーとフルートによる複両面段ボールあるいは複複両面段ボール箱を使用して収納されている。
【0007】
また、工業用の小物部品類等のような比較的小さな輸送物は、所定の数量をまとめて一つの袋あるいは通い箱と言われるプラスチック製の容器あるいは樹脂含浸ボード箱または木箱等に収納して輸送されている。
【0008】
この場合、輸送物が収納された容器内でお互いに衝突しないように発泡スチロールの切断片あるいはプラスチック樹脂ビーズあるいはシュレッダのチップ等から成る緩衝材を容器内に入れ、破損、傷付き等を防止し緩衝性を高めている。
【0009】
または、いつも同様の形状の輸送物を一定個所に輸送する場合の通い箱であれば、通い箱に仕切りを設け輸送物の破損、傷付き等を防止している。
【0010】
他方、引越時のお椀、皿、お茶碗あるいは装飾品等は工業用の小物部品類と略同じ様に一つの袋あるいは段ボール箱またはプラスチック製の容器等に収納されることもある。
【0011】
また、多くは一つずつ新聞紙またはエンボス加工等が施されているクレープ状シートあるいは発泡プラスチックシートあるいは空気ポケットを有する積層シートの緩衝材等で包装されている。
【0012】
緩衝材等で一つずつ包装し、梱包箱内に詰め込まれることで振動や衝撃等で破損あるいは傷付き等を防止し、緩衝性を高めている。
【0013】
【発明が解決しようとする課題】
ところが、洗濯機や冷蔵庫等の大型電化製品を輸送する場合に段ボール等の上下四隅に使用される発泡スチロール製の緩衝材は所定形状に成形し、披包装物の形状や大きさが変われば、それに応じた緩衝材を使用する必要がある。
【0014】
この為に、緩衝材の汎用性が極めて少なく、また金型や素材等を新規に作製し、緩衝材を新たに成形するために高価に成るという欠点がある。
【0015】
また、一つの袋あるいは通い箱等に収納される比較的小さな輸送物の破損や傷付き等防止の為に使用される樹脂ビーズは、緩衝性に乏しく、且つ梱包を解く場合に飛散し、後処理が大変面倒になるという問題がある。
【0016】
また、多用されている空気ポケットを有する積層シートの緩衝材はポリエチレン等の熱可塑性樹脂よりなる薄肉のシート材で全体が柔軟で変形性に富み優れた緩衝機能を発揮することから、種々の製品の緩衝材として広く多用されている。
【0017】
しかし、この空気ポケットを有する積層シートは薄肉のシート材であるので空気粒が破裂し易すく、強度を高めようとして厚肉のシート材により構成すればコストがかかるという問題がある。
【0018】
また、すべてが熱可塑性樹脂より出来ている為に廃棄処分の問題が発生しているほかに、空気ポケットを有する為に非常に嵩張る事も大きな問題に成っている。
【0019】
また、使用済素材を再利用して緩衝材を作り、低価格化と環境保護の面から望まれ出現したのがシュレッダのチップである。
【0020】
シュレッダのチップはそのまま使用したり、あるいはチップをビニール等の袋に詰めて緩衝材として使用されている。
【0021】
しかし、シュレッダからのチップをそのまま使用すると輸送物に紙粉が付着したり、あるいは開封時に紙紛が飛び散るなど好ましくない問題がある。
【0022】
また、シュレッダからのチップをビニール等の袋に詰めた緩衝材は、袋詰め作業が手作業により行うことが多く、そのために手間がかかる上に、周囲に紙片類や紙粉が飛び散り好ましくない問題がある。
【0023】
また、発泡塩化ビニールフォームやウレタンまたは発泡スチロールの緩衝材は石油化学製品であるため、廃棄処分に問題がある。
【0024】
さらに、パルプモールドは披包装物の形状や大きさが変われば、それに応じた包装部材の金型を作製し製造する為に製造経費が高く成るほかに、製造した製品の乾燥に多くのエネルギーを要し、且つ湿度により圧縮強度等が著しく低下するという問題がある。
【0025】
また、乾燥設備等が大掛かりで設備費用が掛かると言う問題と緩衝材の汎用性が極めて少なく、披包装物の形状や大きさが変われば、金型や網付け等を新規に作製する為にパルプモールドを作製する日数が非常に長いと言う問題もある。
【0026】
また、成形後の乾燥温度、乾燥速度等乾燥条件によって製品形状のバラツキが非常に大きく、また互換性に乏しいと言う問題がある。
【0027】
このように緩衝機能を有する包装材料としては種々のものがあるが、いずれも汎用性、後処理の容易性、強度、経済性を兼備えた緩衝包装部材はなく、新たな緩衝包装部材の出現が望まれているのが現状である。
【0028】
本発明は、上記した従来の問題点に鑑みてなされたものであり、緩衝性に優れ、汎用性があり、後処理の容易性、作業性、経済性を兼備えた筒状の緩衝包装部材を提供することを目的とする。
【0029】
【課題を解決するための手段】
本発明は上記の課題を解決するために、まず請求項1に係る発明は、 クラフト紙あるいは中芯原紙等からなる紙質の基材の少なくても一方に熱可塑性樹脂層を形成した積層シートにエンボス加工を施してなる緩衝シートを、前記熱可塑性樹脂層の一部で接着シールすることにより筒状に形成されていることを特徴とした筒状の緩衝包装部材である。
【0030】
【発明の実施の形態】
本発明の筒状の緩衝包装部材を実施の形態に沿って以下に図面を参照しながら詳細に説明する。図1〜図5は本発明の一実施例を示す。図1(a)は本発明に係る筒状の緩衝包装部材の表面状態を示す平面図、(b)は図1(a)の筒状の緩衝包装部材のS部表面拡大を示す拡大図、(c)は図1(a)のA−A′断面を示す断面図、図2(a)は本発明に係る一実施例の三方シール包装体を示す平面図、(b)は図2(a)のB−B′断面を示す断面図、図3は本発明に係る一実施例の合掌シール包装体を示す平面図、(b)は図3(a)のC−C′断面を示す断面図、図4(a)は本発明に係る一実施例の封筒貼りシール包装体を示す平面図、(b)は図4(a)のD−D′断面を示す断面図、図5は本発明に係る一実施例の三方シール包装体の製袋加工を示す平面図である、
【0031】
本発明の緩衝包装部材シート1は紙基材2に熱可塑性樹脂層3を有する積層シートにエンボス加工が形成される。
【0032】
エンボス加工は凹凸の模様を彫刻した雄雌の金型ロール間を通して型付けするドライエンボス加工が主に施されている。
【0033】
また、積層シートを雄雌の金型によって常温でドライエンボス加工(以下エンボス加工と略す)を施すことも出来るが、熱可塑性樹脂層3に使用されている熱可塑性樹脂の最高使用温度から軟化以下の温度でエンボス加工を施すことにより凹凸状突起4、5が深く、安定した品質の緩衝包装部材が形成される。
【0034】
また、積層シートに使用される熱可塑性樹脂層3に使用されている熱可塑性樹脂の最高使用温度から軟化以下の温度でエンボス加工を施すことにより凹凸状突起の加工後の戻りが少なくなり、均一な凹凸状突起4、5が形成される。
【0035】
エンボス加工で紙基材2に割れ現象が出た場合は適度の水分を紙基材2にスプレーしながらエンボス加工を施すかあるいは積層シートを調湿してからエンボス加工を施すことが望ましい。
【0036】
図1(a)は本発明の緩衝包装部材1の一実施例体様を示す平面図であって、緩衝包装部材1の表面は凹凸状突起4、5が形成されている。
【0037】
緩衝包装部材1の凸部突起4は千鳥状の配置で半球形状のエンボス加工が形成されている。
【0038】
図1(b)に示す凸部突起4は緩衝包装部材1全面に形成され、水平方向のピッチPが略5mm〜8mm程度で千鳥状にエンボス加工が形成されている。
【0039】
また、凸部突起4は略直径2mm〜6mm程度の半球形状にエンボス加工が施され、その深さは略0.6mm〜3.5mm程度に形成されている。
【0040】
一方、図1(b) に示す凹部5は凸部突起4と凸部突起4の略中心に形成され、水平方向のピッチが凸部突起4と同じように略5mm〜8mm程度で千鳥状にエンボス加工が形成されている。
【0041】
また、凹部5は略直径2mm〜6mm程度で凸部突起4と同様の半球形状のエンボス加工が形成され、その深さは略0.6mm〜3.5mm程度に形成されている。
【0042】
また、本発明の緩衝包装部材シート1が形成される一実施例が図1(c)に示すように、エンボス加工され、凹凸状突起4、5が形成されている緩衝包装部材シート1は、外側面は紙基材2が形成され、内側面は熱可塑性樹脂層3が形成されている。
【0043】
外側面に形成されている紙基材2はクラフト紙の110g/m〜210g/m 、あるいは中芯原紙の135g/m〜185g/m 等程度の用紙が使用される。
【0044】
特に、紙基材2はエンボス加工適性を大きく左右することから紙中の繊維の繊維長、繊維径、内孔径、繊維の形状などの点でクラフト紙はエンボス加工にも充分耐えられる紙基材2である。
【0045】
また、エンボス加工された紙基材2は緩衝性以外に作業時の風合い(手触りの良さ、しなやかさ等)の良さにより作業効率も向上する。
【0046】
このように、エンボス加工された紙基材2の風合いが重要となる事からクラフト紙はエンボス加工により、より一層風合いが良くなる優れた紙基材2である。
【0047】
また、中芯原紙は密度が小さくエンボス加工適性に優れ、深いエンボス加工を形成すことができるほか、紙の価格も安価である。
【0048】
さらに、引越し時にお茶碗、皿、等の家庭用食器類を梱包包装する筒状の緩衝包装部材1として、緩衝性、あるいは作業する上で効率のよい紙基材2としてはクラフト紙の170g/m 程度の用紙が好ましい。
【0049】
また、内側面の熱可塑性樹脂層3として低密度ポリエチレン、直鎖状ポリエチレン、中密度ポリエチレン、高圧法密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、エチレン・プロピレン供重合体、ポリ塩化ビニル等が使用される。
【0050】
紙基材2との貼着は各種のラミネーションが可能であるが紙基材2との接着性、生産性等からエキストルーダーによるエクストルージョンラミネーションが好ましい。
【0051】
また、紙基材2の内側面に形成される熱可塑性樹脂層3は熱可塑性樹脂であれば何れの樹脂でもよいがエクストルージョンラミネーション適性あるいはヒートシール強度、作業適性等から低密度ポリエチレンが好ましい。
【0052】
さらに、紙基材2の一方に熱可塑性樹脂層3が形成された積層シートはエンボス加工する前に会社名、マーク、ロゴマーク、図柄あるいは広告媒体用等の印刷加工を施すことが出来る。
【0053】
紙基材2表面および熱可塑性樹脂層3表面の印刷はフレキソ印刷加工あるいはグラビア印刷加工等を施す事ができる。
【0054】
さらに、エンボス加工は紙基材2単体に加工した後に、内側面に熱可塑性樹脂層3を形成してもよいが、望ましくは紙基材2に熱可塑性樹脂層3を形成した後にエンボス加工を形成する方が作業性も良く、且つ品質の均等性の良い緩衝包装部材1が形成される。
【0055】
また、熱可塑性樹脂層3の厚みは12μ〜60μ程度が形成されるが、シール強度を考慮すると35μ〜45μ程度が好ましい。
【0056】
また、梱包する輸送物7によって紙紛が問題となる場合は紙基材2の両面に熱可塑性樹脂層3を形成することが好ましい。
【0057】
紙粉防止を目的とする場合には紙基材2表面の熱可塑性樹脂層3は12μ〜15μ程度の厚みが形成される。
【0058】
また、紙基材2表面に12μ〜15μ程度の熱可塑性樹脂層3が形成された場合、内側面の熱可塑性樹脂層3はシール強度を考慮して35μ〜45μ程度の厚さが好ましい。また、包装体として三方フラットシール包装体8か三方ピロー包装体を形成する事が最適である。
【0059】
図1(a)に示す本発明の筒状の緩衝包装部材1は製袋加工機により図2(a)に示すような三方フラット包装体8あるいは 図3(a)に示すような合掌貼り包装体9または 図4(a)の筒状の封筒貼り包装体11等の所定の大きさに形成される。
【0060】
図2(a)に示す三方フラット包装体8のシール部6は熱可塑性樹脂層3同士が加熱加圧により接着シールされる。
【0061】
シール部6のシール幅は3mm〜15mm程度に形成されるが包装体の大きさあるいは梱包する輸送物7の大きさ、重量、形状等によってシール幅は異なってくる。
【0062】
また、シール部6以外の輸送物7の収容部は図2(b)に示すように凹凸状突起4、5の熱可塑性樹脂層3が形成されている。
【0063】
また、輸送物7の収容部外側面は凹凸状突起4、5の紙基材2が形成されている。
【0064】
シール部6は加熱加圧により接着シールされる為に凹凸状突起4、5が潰され平らになるので梱包包装された輸送物7がなんであるか、あるいはどこの場所、または棚に置くか等の表示や整理番号等をマジック等で容易に記入する事ができる。
【0065】
また、凹凸状突起4、5が潰され平らになるためにラベルを貼る場合にも貼着し易く輸送中に剥がれる事がない。
【0066】
また、図3(a)に示すような合掌貼りシール包装体9の胴部中央の合掌貼りシール12は凹凸状突起4、5が潰され平らになるが合掌貼りシール12の内側部は図3(b)に示すような凹凸状突起4、5が形成され、合掌貼りシール包装体9に収納される輸送物7の収納部全面に凹凸状突起4、5で覆われる状態に形成される。
【0067】
合掌貼りシール部12のシール幅は三方フラット包装体8と同様に梱包する輸送物7の大きさ、重量、形状等によってシール幅は異なってくるが多くは3mm〜15mm程度のシール幅に形成される。
【0068】
また、胴の部分に合掌貼りシール12を施し底部をシール6せずに筒状で輸送物7を梱包包装して使用することにより、不揃いの長さの輸送物7にも適する緩衝包装部材1が得られる。
【0069】
また、図4(a)は封筒貼りシール包装体11で筒状に形成され、筒状包装体の短辺方向の中央部で熱可塑性樹脂層3と紙基材2表面が水平に加熱加圧により接着シールされ図4(b)に示すような封筒貼り状に形成される。
【0070】
封筒貼りシール包装体11は熱可塑性樹脂層3と紙基材2表面が図4(b)に示すようにシール部6が水平に貼り合わされるために凹凸突起は加熱加圧により潰され平らに形成される。
【0071】
三方フラット包装体8同様に凹凸状突起4、5が潰され平らになるために、梱包包装された輸送物7がなんであるか表示する時ににマジック等で記入し易く、またラベルを貼る場合にも貼着し易くなる。
【0072】
封筒貼りシールされた筒状の緩衝包装部材1は筒状に形成されているために輸送物7を梱包包装する場合に筒状の緩衝包装部材1の左右に開口部が形成されているために、輸送物7等を挿入する場合に挿入方向を選択することが無く高率の良い梱包包装作業が出来る。
【0073】
また、挿入した後で筒状緩衝包装部材1の左右を折り畳むかツイストするだけで梱包包装作業が完了する。
【0074】
封筒貼りシール包装体11のシール幅は三方フラット包装体8あるいは合掌貼り包装体12と同様に梱包する輸送物7の大きさ、重量、形状等によってシール幅は異なってくるが多くは5mm〜15mm程度のシール幅が形成される。
【0075】
封筒貼りシール包装体11のシール部10は紙基材2表面と紙基材2の裏面に形成されている熱可塑性樹脂層3が加熱加圧により接着シールされるためにシール強度が弱くなる。
【0076】
この為に、熱可塑性樹脂層3を40μ〜60μ程度の厚めに形成するか、あるいはシール強度が必要なときには紙基材2の両面に熱可塑性樹脂層3を形成することが好ましい。
【0077】
この場合、紙基材2の表側面の熱可塑性樹脂層3は12μ〜30μ程度の厚みが形成される。
【0078】
紙基材2の両面に熱可塑性樹脂層3を施すこと事で紙粉の防止も兼ねる場合においても紙基材2の表側面に12μ〜20μ程度の熱可塑性樹脂層3を施すことで封筒貼りシール包装11の接着強度を向上する事が出来る。
【0079】
また、三方フラット包装体8あるいは合掌貼りシール包装体12と同様に胴部シール以外に底部をシールして筒状に製袋加工を施した底部のある封筒貼り包装体11も使用される。
【0080】
また、本発明の筒状に三方フラットシールした包装体8が製袋加工機で製袋加工される一実施例を図5に示す。
【0081】
図5に示すように本発明の緩衝包装部材1を製袋加工機上で半折加工し、縦シール部で流れ方向の緩衝包装部材1の両端部を加熱加圧により接着シール6する。
【0082】
さらに次工程の横シール部で一定の間隔で加熱加圧により接着シール6されたあとに流れ方向の紙幅中央部がスリット加工13され、デリバリー部で横シール幅の中央部で一定の長さにカット部14でカットされ図2(a)に示す三方をシールした筒状の緩衝包装部材1である三方フラットシール包装体8が形成される。
【0083】
本発明の緩衝包装部材1は筒状に形成されている為に輸送物7を包装梱包するときに筒状の緩衝包装部材1に輸送物7を挿入するだけで梱包箱に詰め込むか、あるいは緩衝包装部材1の挿入口を梱包箱に詰め込む時に折り曲げる程度の作業で梱包箱詰めが容易に出来る。
【0084】
さらに、包装作業や梱包箱詰め作業によって輸送物7の破損や損傷が生じる為に熟練者や専門の人によって包装梱包作業が行われていたが、本発明の筒状の緩衝包装部材1を使用することにより輸送物7を輸送中に破損あるいは損傷等を生じることがない包装作業や梱包箱詰め作業が熟練者でなくても容易に出来る。
【0085】
また、包装作業や梱包箱詰め作業が熟練者でなくても容易に出来るだけでなく包装作業や梱包箱詰め作業時間が短時間で完了することが出来るようになった。また筒状の緩衝包装部材に置く場所や棚等を表示できる為に梱包開封後の整理等が円滑に短時間で出来る。
【0086】
【発明の効果】
本発明に係わる筒状の緩衝包装部材は積層シートに多数の凹凸状突起が形成され、さらに筒状に製袋加工が施され、緩衝性に優れ、且つ包装作業や梱包箱詰め作業が容易で高率的に行えるほかに、緩衝包装部材は汎用性があり、使用後の廃棄等の処理も紙製品と同様に容易に廃棄処理が出来るなど、経済性を兼ねそなえた筒状の緩衝包装部材である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cushioning packaging member having an excellent buffering action of a paper base material, easily being disposed of, and having versatility, workability, and economy.
[0002]
[Prior art]
When transporting industrial parts or equipment, jigs, or bowls, dishes, decorations, electric appliances, etc. when moving, packaging or packing is performed to prevent damage or damage to these transported goods .
[0003]
Such conventional packaging or packaging techniques include, for industrial parts, jigs, tools, accessory parts, measuring instruments, etc., in advance, according to the structure, shape, material, transportation method, etc. of the transported material, cushion material. Packaging and packaging are performed using a wooden box, a cardboard box, or the like.
[0004]
Also, when transporting large home appliances such as washing machines and refrigerators, transport packages are designed in advance in consideration of safety factors against impact, drop, vibration, compression, and the like of transported items.
[0005]
Transport packaging design includes designing wooden structures, designing paper containers, cardboard, etc., cushioning design, anti-corrosion, moisture-proof, etc., as well as packaging techniques such as fixing method, sealing, bundling, etc. And the packaging structure, members, configuration, etc. are determined.
[0006]
As a result of transport packaging design, when transporting large home appliances such as washing machines and refrigerators, pulp molds or foam molded to correspond to the shape at least in the upper and lower four corners of the washing machines and refrigerators to be transported A cushioning material such as vinyl chloride foam, urethane or styrofoam is applied, and is stored using a double-sided double-sided cardboard or double-sided double-sided cardboard box with a predetermined liner and flute designed for cardboard.
[0007]
In addition, relatively small transported goods such as industrial small parts are stored in a predetermined amount in a single bag or a plastic container called a returnable box, a resin-impregnated board box, a wooden box, or the like. Transported.
[0008]
In this case, a cushioning material consisting of a cut piece of styrofoam or a plastic resin bead or a shredder chip is put into the container so as not to collide with each other in the container in which the transported goods are stored. Is increasing the character.
[0009]
Alternatively, in the case of a returnable box for transporting a transported article of the same shape to a certain place, a partition is provided in the returnable box to prevent the transported article from being damaged or damaged.
[0010]
On the other hand, bowls, plates, bowls, decorations, and the like at the time of moving may be housed in one bag, a cardboard box, a plastic container, or the like, in substantially the same manner as small industrial parts.
[0011]
Many are individually wrapped in a cushioning material such as a crepe sheet or embossed crepe sheet, a foamed plastic sheet, or a laminated sheet having air pockets.
[0012]
Each of them is wrapped one by one with a cushioning material or the like, and packed in a packing box to prevent damage or damage due to vibration or impact, etc., thereby enhancing the cushioning property.
[0013]
[Problems to be solved by the invention]
However, when transporting large appliances such as washing machines and refrigerators, foamed polystyrene cushioning materials used in the upper and lower four corners of cardboard etc. are molded into a predetermined shape, and if the shape and size of the package change, It is necessary to use the appropriate cushioning material.
[0014]
For this reason, there is a disadvantage that the versatility of the cushioning material is extremely low, and it is expensive to newly manufacture a mold and a material and to newly form the cushioning material.
[0015]
In addition, resin beads used to prevent breakage or damage of relatively small packages stored in a single bag or returnable box have poor buffering properties, and are scattered when unpacking. There is a problem that processing becomes very troublesome.
[0016]
In addition, the cushioning material of a laminated sheet having air pockets, which are frequently used, is a thin sheet material made of a thermoplastic resin such as polyethylene, and is entirely flexible, highly deformable, and exhibits an excellent cushioning function. Is widely used as a cushioning material.
[0017]
However, since the laminated sheet having the air pocket is a thin sheet material, there is a problem that air particles are easily ruptured, and if a thick sheet material is used to increase the strength, the cost increases.
[0018]
In addition to the problem of disposal due to the fact that all are made of a thermoplastic resin, the fact that they have air pockets and become very bulky is also a major problem.
[0019]
In addition, shredder chips have been desired and emerged from the viewpoints of cost reduction and environmental protection, by creating a cushioning material by reusing used materials.
[0020]
Shredder chips are used as they are, or chips are packed in bags such as vinyl and used as cushioning material.
[0021]
However, if the chips from the shredder are used as they are, there are undesired problems such as paper dust adhering to the transported goods or scattering of the paper dusts when opening.
[0022]
In addition, cushioning materials in which chips from a shredder are packed in a bag of vinyl or the like often require manual work for bagging, which is troublesome, and undesired problems such as scattering of paper pieces and paper dust around. There is.
[0023]
In addition, since the foamed PVC foam, urethane or styrofoam buffer is a petrochemical product, there is a problem in disposal.
[0024]
In addition, if the shape and size of the pulp mold change, the manufacturing cost will increase due to the need to manufacture and manufacture the mold for the packaging member, and in addition, a lot of energy will be required to dry the manufactured product. In addition, there is a problem that the compressive strength and the like are significantly reduced due to humidity.
[0025]
In addition, there is a problem that the equipment cost is high due to the large size of the drying equipment, and the versatility of the cushioning material is extremely small.If the shape and size of the packaging change, it is necessary to make new molds and netting. There is also a problem that the number of days for making the pulp mold is very long.
[0026]
Further, there is a problem that the shape of the product varies greatly depending on drying conditions such as a drying temperature and a drying speed after molding, and compatibility is poor.
[0027]
As described above, there are various types of packaging materials having a cushioning function, but none of them has general versatility, ease of post-processing, strength, and economy, and a new cushioning packaging member has emerged. It is the present situation that is desired.

In the cushioning packaging member sheet 1 of the present invention, a laminated sheet having a thermoplastic resin layer 3 on a paper base 2 is embossed.
[0032]
The embossing is mainly performed by dry embossing in which a male and female mold roll engraved with an uneven pattern is molded.
[0033]
The laminated sheet may be subjected to dry embossing (hereinafter abbreviated as embossing) at room temperature by male and female molds. However, the laminated sheet may be softened to a temperature lower than the maximum operating temperature of the thermoplastic resin used for the thermoplastic resin layer 3. By performing embossing at the temperature described above, the uneven projections 4 and 5 are deep, and a cushioning packaging member of stable quality is formed.
[0034]
Further, by performing embossing at a temperature not higher than the maximum softening temperature of the thermoplastic resin used for the thermoplastic resin layer 3 used for the laminated sheet and lower than the softening temperature, the return after the processing of the uneven projections is reduced, and The uneven projections 4 and 5 are formed.
[0035]
When the paper substrate 2 is cracked by the embossing, it is preferable to perform the embossing while spraying a suitable amount of water onto the paper base 2 or to perform the embossing after adjusting the humidity of the laminated sheet.
[0036]
FIG. 1A is a plan view showing an embodiment of the cushioning packaging member 1 according to the present invention, in which bumpy projections 4 and 5 are formed on the surface of the cushioning packaging member 1.
[0037]
The convex protrusions 4 of the cushioning packaging member 1 are arranged in a staggered manner, and have a hemispherical embossing.
[0038]
The projections 4 shown in FIG. 1B are formed on the entire surface of the cushioning packaging member 1, and are embossed in a staggered manner at a horizontal pitch P of about 5 mm to 8 mm.
[0039]
The projection 4 is embossed into a hemispherical shape having a diameter of about 2 mm to 6 mm, and has a depth of about 0.6 mm to 3.5 mm.
[0040]
On the other hand, the concave portion 5 shown in FIG. 1B is formed substantially at the center of the convex protrusion 4, and the pitch in the horizontal direction is approximately 5 mm to 8 mm like the convex protrusion 4 in a staggered manner. Embossing is formed.
[0041]
The concave portion 5 has a diameter of about 2 mm to 6 mm, and is formed by the same hemispherical embossing as that of the convex protrusion 4, and has a depth of about 0.6 mm to 3.5 mm.
[0042]
Further, as shown in FIG. 1 (c), an embodiment in which the cushioning packaging member sheet 1 of the present invention is formed is embossed, and the cushioning packaging member sheet 1 in which the uneven projections 4 and 5 are formed, A paper substrate 2 is formed on the outer side surface, and a thermoplastic resin layer 3 is formed on the inner side surface.
[0043]
Paper substrate 2 which is formed on the outer surface kraft paper 110g / m 2 ~210g / m 2 or a corrugating medium 135g / m 2 ~185g / m 2, etc. about the paper, are used.
[0044]
In particular, since the paper base material 2 greatly affects the suitability for embossing, kraft paper is a paper base material that can withstand embossing sufficiently in terms of the fiber length, fiber diameter, inner hole diameter, and fiber shape of the fibers in the paper. 2.
[0045]
In addition, the work efficiency of the embossed paper base material 2 is improved due to the good texture (good touch, suppleness, etc.) at the time of work, in addition to the cushioning property.
[0046]
As described above, since the texture of the embossed paper base material 2 is important, the kraft paper is an excellent paper base material 2 whose texture is further improved by embossing.
[0047]
In addition, the core base paper has a small density, is excellent in embossing suitability, can form deep embossing, and is inexpensive.
[0048]
Further, as a cylindrical buffer packaging member 1 for packing and wrapping household tableware such as a bowl, a dish, etc. at the time of moving, 170 g / kraft paper is used as a buffer base material or a paper base material 2 which is efficient in work. m 2 about the paper is preferred.
[0049]
Further, as the thermoplastic resin layer 3 on the inner surface, low density polyethylene, linear polyethylene, medium density polyethylene, high pressure method density polyethylene, high density polyethylene, polypropylene, ethylene / propylene copolymer, polyvinyl chloride, etc. are used. .
[0050]
Various laminations are possible for the attachment to the paper substrate 2, but extrusion lamination by an extruder is preferable from the viewpoint of adhesion to the paper substrate 2 and productivity.
[0051]
The thermoplastic resin layer 3 formed on the inner surface of the paper substrate 2 may be any resin as long as it is a thermoplastic resin, but low density polyethylene is preferable from the viewpoint of extrusion lamination suitability, heat sealing strength, workability, and the like.
[0052]
Further, the laminated sheet in which the thermoplastic resin layer 3 is formed on one side of the paper base material 2 can be subjected to a printing process such as a company name, a mark, a logo mark, a design or an advertisement medium before embossing.
[0053]
The printing on the surface of the paper substrate 2 and the surface of the thermoplastic resin layer 3 can be performed by flexographic printing or gravure printing.
[0054]
Further, in the embossing, the thermoplastic resin layer 3 may be formed on the inner surface after processing the paper base 2 alone, but it is preferable that the embossing is performed after the thermoplastic resin layer 3 is formed on the paper base 2. Forming the cushioning packaging member 1 improves workability and uniformity of quality.
[0055]
The thickness of the thermoplastic resin layer 3 is about 12 μm to 60 μm, and is preferably about 35 μm to 45 μm in consideration of the sealing strength.
[0056]
Further, when paper dust becomes a problem due to the package 7 to be packed, it is preferable to form the thermoplastic resin layers 3 on both sides of the paper substrate 2.
[0057]
When the purpose is to prevent paper dust, the thickness of the thermoplastic resin layer 3 on the surface of the paper substrate 2 is about 12 to 15 μm.
[0058]
When the thermoplastic resin layer 3 of about 12 to 15 μ is formed on the surface of the paper base material 2, the thickness of the thermoplastic resin layer 3 on the inner side is preferably about 35 to 45 μ in consideration of the sealing strength. It is optimal to form a three-sided flat seal package 8 or a three-way pillow package as a package.
[0059]
The cylindrical buffer packaging member 1 of the present invention shown in FIG. 1A is formed by a bag making machine with a three-way flat package 8 as shown in FIG. The body 9 or the tubular envelope-attached package 11 in FIG.
[0060]
In the sealing portion 6 of the three-way flat package 8 shown in FIG. 2A, the thermoplastic resin layers 3 are adhesively sealed by heating and pressing.
[0061]
The seal width of the seal portion 6 is formed to be about 3 mm to 15 mm, but the seal width varies depending on the size of the package or the size, weight, shape, etc. of the package 7 to be packed.
[0062]
In addition, as shown in FIG. 2B, the thermoplastic resin layer 3 of the uneven protrusions 4 and 5 is formed in the accommodation portion of the transported material 7 other than the seal portion 6.
[0063]
Further, the paper base 2 of the uneven protrusions 4 and 5 is formed on the outer surface of the accommodation portion of the transported article 7.
[0064]
Since the sealing portion 6 is adhesively sealed by heating and pressing, the uneven projections 4 and 5 are crushed and flattened. Therefore, what is the packaged and packaged goods 7, or where to put it on a shelf, etc. Can be easily entered by magic or the like.
[0065]
Also, when the label is applied because the uneven projections 4 and 5 are crushed and flattened, the label is easily attached and does not peel off during transportation.
[0066]
As shown in FIG. 3 (a), the palm joint sticker 12 at the center of the trunk of the joint palm sticker package 9 has the uneven projections 4 and 5 crushed and flattened. The uneven projections 4 and 5 as shown in FIG. 2B are formed, and are formed so as to be covered with the uneven projections 4 and 5 over the entire storage portion of the package 7 stored in the palm-sealed seal package 9.
[0067]
As in the case of the three-way flat package 8, the seal width of the seal portion 12 varies depending on the size, weight, shape, etc. of the package 7 to be packed, but is often set to a seal width of about 3 mm to 15 mm. You.
[0068]
In addition, by providing a seal 12 on the trunk portion and packing and packaging the package 7 in a tubular shape without using the seal 6 at the bottom, the cushioning packaging member 1 suitable for the package 7 having an irregular length is used. Is obtained.
[0069]
FIG. 4 (a) shows an envelope-attached seal package 11 formed in a tubular shape, and the surface of the thermoplastic resin layer 3 and the surface of the paper substrate 2 are horizontally heated and pressed at the center in the short side direction of the tubular package. To form an envelope-attached shape as shown in FIG.
[0070]
As shown in FIG. 4 (b), since the surface of the thermoplastic resin layer 3 and the surface of the paper base material 2 are horizontally bonded with the sealing portion 6 as shown in FIG. It is formed.
[0071]
As in the case of the three-way flat package 8, the uneven protrusions 4 and 5 are crushed and flattened, so that it is easy to fill in with magic or the like when indicating what the packaged package 7 is, and when a label is attached. Is also easy to stick.
[0072]
Since the cylindrical buffer packaging member 1 sealed with the envelope is formed in a cylindrical shape, the opening portions are formed on the left and right of the cylindrical buffer packaging member 1 when packing and packaging the transported goods 7. In addition, in the case of inserting the transported article 7 or the like, the packing direction can be efficiently performed without selecting the insertion direction.
[0073]
Further, the packing and packaging operation is completed only by folding or twisting the left and right sides of the cylindrical buffer packaging member 1 after the insertion.
[0074]
The seal width of the envelope-attached seal package 11 varies depending on the size, weight, shape, etc. of the package 7 to be packed in the same manner as the three-way flat package 8 or the gasket-paste package 12, but is often 5 mm to 15 mm. A degree of seal width is formed.
[0075]
Since the thermoplastic resin layer 3 formed on the surface of the paper base material 2 and the back surface of the paper base material 2 is bonded and sealed by heating and pressing, the sealing portion 10 of the envelope-attached seal package 11 has low sealing strength.
[0076]
For this reason, it is preferable that the thermoplastic resin layer 3 be formed to have a relatively large thickness of about 40 μm to 60 μm, or that the thermoplastic resin layer 3 be formed on both sides of the paper substrate 2 when sealing strength is required.
[0077]
In this case, the thickness of the thermoplastic resin layer 3 on the front surface of the paper substrate 2 is about 12 μm to 30 μm.
[0078]
Even in the case where the paper dust is prevented by applying the thermoplastic resin layers 3 on both surfaces of the paper base material 2, the envelope is adhered by applying the thermoplastic resin layer 3 of about 12 μ to 20 μ on the front surface of the paper base material 2. The adhesive strength of the seal package 11 can be improved.
[0079]
In addition, similarly to the three-sided flat package 8 or the gasket-sealed seal package 12, an envelope-attached package 11 having a bottom, which is sealed at the bottom and bag-formed into a cylindrical shape, is used in addition to the body seal.
[0080]
FIG. 5 shows an embodiment in which the package 8 of the present invention, which is three-dimensionally flat-sealed in a tubular shape, is subjected to bag making by a bag making machine.
[0081]
As shown in FIG. 5, the buffer wrapping member 1 of the present invention is half-folded on a bag making machine, and both ends of the buffer wrapping member 1 in the flow direction are adhesively sealed 6 by heating and pressing at the vertical seal portion.
[0082]
Further, after the adhesive seal 6 is applied by heating and pressing at a constant interval in the horizontal seal portion in the next process, the central portion of the paper width in the flow direction is slit 13, and the central portion of the horizontal seal width in the delivery portion has a predetermined length. A three-way flat seal package 8 which is a cylindrical buffer packaging member 1 which is cut by the cut portion 14 and is sealed on three sides as shown in FIG. 2A is formed.
[0083]
Since the buffer packaging member 1 of the present invention is formed in a tubular shape, when packaging the transported product 7, the transported product 7 is inserted into the cylindrical buffer packaging member 1 by simply inserting the transported product 7 into the packing box. The packing box can be easily packed by the work of bending the insertion opening of the packaging member 1 into the packing box.
[0084]
Further, the packing and packing work is performed by a skilled person or a specialized person because the packing material is broken or damaged by the packing and packing work. However, the cylindrical buffer packing member 1 of the present invention is used. As a result, a packaging operation and a packing operation that do not cause breakage or damage during transportation of the transported item 7 can be easily performed by a non-expert.
