Description

【0001】
【発明の属する技術分野】
本発明は、耐熱水性の含浸紙を最外面に使用したレトルト殺菌処理可能な紙容器に関する。
【0002】
【従来の技術】
近時、ポリウレタン系樹脂、ポリイソシアネート系樹脂、アクリル系樹脂、エポキシ系樹脂および硝化綿系樹脂から選ばれる1種類又は2種類以上の樹脂をセルロース繊維構造物に含浸させた含浸紙がトレー、パウチなどの容器として提供されている。
【0003】
その場合には、例えば、含浸紙/酸化ケイ素の薄膜を蒸着したポリエチレンテレフタレートフィルム/ナイロンフィルム/未延伸ポリプロピレンフィルムなどのような層構成からなる複合紙にして使用されている。
【0004】
そしてこのような構成の複合紙をパウチやトレーのような容器状に成形し、ヒートシールやインパルスシールのようなシール手段を用いて密封シールした場合には、パウチのシール部分や紙トレーのトレーと蓋材とのシール部分に含浸紙の樹脂が熱により焦げて変色によるシール跡が残り、見栄えが良くないし、シール不良を生じる場合もあり、問題となっている。
【0005】
【発明が解決しようとする課題】
本発明は、耐熱水性の含浸紙を使用した複合紙を成形等して得られた容器の密封シール時における以上のような問題点を解決するためになされたもので、シール時にシール跡が残らず、かつ、完全な密封シールが可能な含浸紙用のシーラント剤と該シーラント剤を使用した容器を提供することを課題とする。
【0006】
【課題を解決するための手段】
本発明の請求項1の発明は、ポリウレタン系樹脂、ポリイソシアネート系樹脂、アクリル系樹脂、エポキシ系樹脂および硝化綿系樹脂から選ばれる1種類又は2種類以上の樹脂をセルロース繊維構造物に含浸させた含浸紙を最外面に配置し、最内面にシーラント層を設けた複合紙から成るレトルト殺菌処理可能な紙容器であって、該シーラント層を形成するシーラント材として、120°C以上、130°C以下の融点を有するポリエチレン樹脂を用いたことを特徴とする、レトルト処理可能な紙容器である。
【0007】
このように請求項1記載の発明によれば、シーラント層を形成するシーラント材として、120°C以上、130°C以下の融点を有するポリエチレン樹脂を用いているので、容器に成形する際、比較的低温度での密封シールが可能で、そのため、含浸紙の樹脂が熱により焦げて変色によるシール跡が残る可能性が少ない。
【0008】
また、請求項2の発明は、請求項1の発明において、前記含浸紙の坪量が10〜250g/mであることを特徴とする、レトルト処理可能な紙容器である。
【0009】
このように請求項2記載の発明によれば、坪量が10〜250g/mの比較的薄い含浸紙を使用しているので、熱伝導がよくなり、余り温度を上げることなく密封シールすることが可能になる。
【0010】
【発明の実施の形態】
本発明のレトルト処理可能な紙容器を一実施形態に基づいて以下に詳細に説明する。
本発明のレトルト処理可能な紙容器は、例えば、図1に示すような、複合紙をシーラント層を内側にしてシーラント層同士を対向させて、例えば、図2に示すような袋や開口部を蓋材で密封シールしたトレー、カップ等の容器(20)に成形して得られる。
【0011】
さらに具体的に述べるならば、本発明のレトルト処理可能な紙容器は、含浸紙(11)を最外面に配置し、最内面にシーラント層(12)を設けた複合紙(10)を容器状に成形して得られる。
【0012】
含浸紙(11)は、複合紙(10)の主材料で、ポリウレタン系樹脂、ポリイソシアネート系樹脂、アクリル系樹脂、エポキシ系樹脂および硝化綿系樹脂から選ばれる1種類又は2種類以上の樹脂をセルロース繊維構造物に含浸して得られる。
【0013】
また、含浸紙(11)は、熱伝導性が良いため、坪量が10〜250g/m程度の比較的薄いものが好ましく使用できる。
【0014】
複合紙の最内面に設けられるシーラント層(12)を形成するシーラント材としては、120°Cの蒸気あるいは熱水で加圧加熱するという殺菌条件に耐える必要があるため、120°C〜130°Cの融点を持つポリエチレン樹脂が好ましく使用できる。
【0015】
複合紙(10)の一般的な層構成としては、ガスバリア性等を考慮して、容器がトレーやカップとした場合には、容器本体(21)は、例えば、〔容器内側〕シーラント層(12)/エチレン・ビニルアルコール共重合体/ポリエチレン/含浸紙(11)〔容器外側〕のような層構成の複合紙が使用され、蓋材(22)は、例えば、〔容器内側〕シーラント層(12)/ナイロン/酸化ケイ素の薄膜を蒸着法により設けた延伸ポリエステルフィルム/坪量が10〜250g/mの含浸紙(11)〔容器外側〕のような層構成の複合紙が使用される。
【0016】
また、容器が袋の場合には、例えば、〔容器内側〕シーラント層(12)/ナイロン/酸化ケイ素の薄膜を蒸着法により設けた延伸ポリエステルフィルム/坪量が10〜250g/mの含浸紙(11)〔容器外側〕のような層構成の複合紙が使用される。
【0017】
複合紙の各層間は、ドライラミネート法等の公知の貼り合わせ法を用いて貼り合わせることができる。
【0018】
こうして作製した複合紙(10)から、三方シール袋などの包装袋あるいはトレー、カップ、ゲーベルトップ型容器、ブリック型容器等の成形容器を公知の作製方法により作製することができる。
【0019】
シーラント層にポリプロピレン樹脂より低融点のポリエチレン樹脂を使用し、また、坪量を10〜250g/mと比較的薄くした含浸紙を使用した本発明の容器は、密封シール部分に樹脂の焦げによる加圧跡がつかず、見栄えの良い容器が作製できる。
【0020】

In this case, for example, a composite paper having a layer structure such as impregnated paper / polyethylene terephthalate film on which a thin film of silicon oxide is deposited / nylon film / unstretched polypropylene film is used.
[0004]
When the composite paper having such a configuration is formed into a container shape such as a pouch or a tray, and hermetically sealed using sealing means such as heat sealing or impulse sealing, the sealing portion of the pouch or the tray of the paper tray is used. The resin of the impregnated paper is scorched by heat and the seal mark due to discoloration remains on the seal portion between the cover and the lid material, resulting in poor appearance and poor sealing.
[0005]
[Problems to be solved by the invention]
The present invention has been made in order to solve the above problems at the time of hermetically sealing a container obtained by molding a composite paper using a hot water-impregnated paper. Another object of the present invention is to provide a sealant for impregnated paper that can be completely hermetically sealed and a container using the sealant.

[0007]
As described above, according to the first aspect of the present invention, a polyethylene resin having a melting point of 120 ° C. or more and 130 ° C. or less is used as a sealant material for forming a sealant layer. Sealing at extremely low temperature is possible, and therefore, there is little possibility that the resin of the impregnated paper is scorched by heat and seal marks due to discoloration remain.
[0008]
The invention according to claim 2 is the paper container capable of retort processing according to claim 1, wherein the impregnated paper has a basis weight of 10 to 250 g / m 2 .
[0009]
As described above, according to the second aspect of the present invention, since relatively thin impregnated paper having a basis weight of 10 to 250 g / m 2 is used, heat conduction is improved, and hermetically sealed without increasing the temperature excessively. It becomes possible.
[0010]

[0012]
The impregnated paper (11) is a main material of the composite paper (10), and is made of one or more resins selected from polyurethane resins, polyisocyanate resins, acrylic resins, epoxy resins, and nitrified cotton resins. It is obtained by impregnating a cellulose fiber structure.
[0013]
Since the impregnated paper (11) has good thermal conductivity, a relatively thin paper having a basis weight of about 10 to 250 g / m 2 can be preferably used.
[0014]
As the sealant material forming the sealant layer (12) provided on the innermost surface of the composite paper, it is necessary to withstand sterilization conditions of pressurizing and heating with steam or hot water at 120 ° C. A polyethylene resin having a melting point of C can be preferably used.
[0015]
As a general layer configuration of the composite paper (10), when the container is a tray or a cup in consideration of gas barrier properties and the like, the container main body (21) includes, for example, a [container inner] sealant layer (12). ) / Ethylene / vinyl alcohol copolymer / polyethylene / impregnated paper (11) A composite paper having a layer structure such as [outside of the container] is used. ) / A stretched polyester film provided with a thin film of nylon / silicon oxide by a vapor deposition method / a composite paper having a layer structure such as an impregnated paper (11) [outer container] having a basis weight of 10 to 250 g / m 2 is used.
