Description
本発明は、環境ホルモン物質を含有しない安全な食品包装用塩化ビニル系樹脂ラップフィルムに関する。 The present invention relates to a safe vinyl chloride resin wrap film for food packaging that does not contain an environmental hormone substance.
ポリ塩化ビニルや塩化ビニル共重合体などの塩化ビニル系樹脂からなるラップフィルムは、青果物、水産物、精肉等の食品の包装用ストレッチフィルムや家庭で用いられるラップフィルムとして広く利用されている。塩化ビニル系樹脂フィルムはＴダイ押出加工法によって成形されるが、押出し加工時の内部発熱によって塩化ビニル系樹脂や配合成分が熱分解して、変色したり、或は成形したフィルムの透明度が低くなる問題点があった。そのため、従来から熱分解に対する安定剤を配合している。食品包装用の塩化ビニル系樹脂の場合は、この安定剤は無毒であることが要求され、従来、トリスノニルフェニルホスファイトが広く用いられてきた。 Wrapping films made of vinyl chloride resins such as polyvinyl chloride and vinyl chloride copolymers are widely used as stretch films for packaging foods such as fruits and vegetables, marine products, and meat, and wrap films used at home. Vinyl chloride resin films are molded by the T-die extrusion process, but the internal heat generation during extrusion causes the vinyl chloride resin and compounding components to thermally decompose and discolor, or the molded film has low transparency. There was a problem. Therefore, a stabilizer against thermal decomposition has been conventionally blended. In the case of vinyl chloride resin for food packaging, this stabilizer is required to be non-toxic, and conventionally trisnonylphenyl phosphite has been widely used.
ところが、近年、トリスノニルフェニルホスファイトは、その分解物であるノニルフェノールがいわゆる環境ホルモン物質に該当するとされるため、この代替物が要望され、種々提案されている。その一つに、（ａ）オレイン酸のカルシウム塩とリシノール酸及び／又は安息香酸のカルシウム塩の混合物に、オレイン酸及び／又はリシノール酸の亜鉛塩を加え、これにさらにエポキシ化大豆油又はエポキシ化アマニ油を加えて加熱して得た加熱溶解物と、（ｂ）トリデシルポリオキシエチレン（４〜１０）リン酸に、リン酸又は亜リン酸を加えて加熱して得た加熱溶解物とを組み合わせて、安定剤として塩化ビニル系樹脂に配合することが提案されている（特許文献１）。
塩化ビニル系樹脂フィルムには可塑剤が配合されるが、食品包装用塩化ビニル系樹脂ラップフィルムの場合は、無毒の可塑剤が要求される。この可塑剤として従来一般にはアジピン酸エステルが用いられているが、安全性に不安を持つ傾向がある。そこで、本発明者らは、安全性がより高いグリセリン脂肪酸エステル及びエポキシ化植物油を可塑剤として用いることを試みた。ところが、このグリセリン脂肪酸エステル及びエポキシ化植物油を可塑剤として使用し、安定剤として上記の特許文献１記載の組成物を配合した場合は、加工時に着色が生じて、製品のラップフィルムの商品価値が低下するという問題点があることを知見した。本発明は、この問題点を解消し、着色がなく、安全性の高い食品包装用塩化ビニル系樹脂ラップフィルムを提供することを目的とする。 A plasticizer is blended in the vinyl chloride resin film, but in the case of a vinyl chloride resin wrap film for food packaging, a non-toxic plasticizer is required. Conventionally, adipic acid esters are generally used as the plasticizer, but there is a tendency to have anxiety in safety. Then, the present inventors tried to use glycerin fatty acid ester and epoxidized vegetable oil having higher safety as a plasticizer. However, when this glycerin fatty acid ester and epoxidized vegetable oil are used as a plasticizer and the composition described in Patent Document 1 is blended as a stabilizer, coloring occurs during processing, and the commercial value of the product wrap film is It was found that there was a problem of a decrease. An object of the present invention is to solve this problem and to provide a vinyl chloride resin wrap film for food packaging that has no coloring and high safety.

本発明の食品包装用塩化ビニル系樹脂ラップフィルムは、環境ホルモン物質を含有しなく、無毒で安全性が高い。また、無色透明で商品価値がよい。 The vinyl chloride resin wrap film for food packaging of the present invention does not contain an environmental hormone substance, is non-toxic and highly safe. Moreover, it is colorless and transparent and has good commercial value.
本発明で用いる塩化ビニル系樹脂としては、ポリ塩化ビニル又は塩化ビニルモノマーと他のモノマー、例えばエチレン、プロピレン、アルキルビニルエーテル、塩化ビニリデン、アクリル酸エステル、酢酸ビニル、メタクリル酸エステル、アクリロニトリル等との共重合体またはポリ塩化ビニルと他のポリマーとのブレンド物があげられる。塩化ビニル系樹脂の重合度は８００〜１１５０が好ましい。重合度が１１５０を超えると、加工性が悪くなり、着色などの原因になる。 Examples of the vinyl chloride resin used in the present invention include polyvinyl chloride or vinyl chloride monomer and other monomers such as ethylene, propylene, alkyl vinyl ether, vinylidene chloride, acrylic acid ester, vinyl acetate, methacrylic acid ester, acrylonitrile and the like. A blend of a polymer or polyvinyl chloride and another polymer is exemplified. The polymerization degree of the vinyl chloride resin is preferably 800 to 1150. When the degree of polymerization exceeds 1150, processability is deteriorated, which causes coloring and the like.
上記塩化ビニル系樹脂に配合する成分（Ａ）の可塑剤としては、グリセリン脂肪酸エステルとエポキシ化植物油とが組み合わせて用いられる。グリセリン脂肪酸エステルは、無毒な可塑剤として知られている。特にグリセリンの酢酸と脂肪酸のエステルが好ましく、例えばグリセリルモノラウリルジアセテート、グリセリルモノステアリルジアセテート、グリセリルモノオレイルジアセテート、グリセリルジラウリルモノアセテート、グリセリルジステアリルモノアセテート、グリセリルジオレイルモノアセテートなどが用いられる。また、エポキシ化植物油は無毒かつ安定剤効果がある低揮発性、低抽出性の可塑剤として知られており、例えばエポキシ化大豆油、エポキシ化亜麻仁油、エポキシ化亜麻仁油脂肪酸ブチルなどが用いられる。 As the plasticizer of the component (A) to be blended with the vinyl chloride resin, glycerin fatty acid ester and epoxidized vegetable oil are used in combination. Glycerin fatty acid esters are known as non-toxic plasticizers. Particularly preferred are glycerin acetic acid and fatty acid esters such as glyceryl monolauryl diacetate, glyceryl monostearyl diacetate, glyceryl monooleyl diacetate, glyceryl dilauryl monoacetate, glyceryl distearyl monoacetate, glyceryl dioleyl monoacetate, etc. It is done. Epoxidized vegetable oil is known as a non-toxic and stabilizer-free low volatility and low extractability plasticizer, such as epoxidized soybean oil, epoxidized linseed oil, epoxidized linseed oil fatty acid butyl, etc. .
上記可塑剤の配合量は、塩化ビニル系樹脂１００質量部に対し、グリセリン脂肪酸エステルは１５〜３０質量部、好ましくは２０〜２５質量部である。またエポキシ化植物油は５〜１５質量部である。エポキシ化植物油は耐寒性、相溶性に問題があるため、７〜１２質量部が好ましい。また、ラップフィルムに適した硬さにするには、可塑剤の合計配合量は、塩化ビニル系樹脂１００質量部に対し２０〜４５質量部、好ましくは２５〜４０質量部である。４０質量部以下であると、カット性がよく小巻の家庭用ラップフィルムに適する。また、上記の可塑剤の他に無毒の可塑剤を併用してもよい。 The blending amount of the plasticizer is 15 to 30 parts by mass, preferably 20 to 25 parts by mass with respect to 100 parts by mass of the vinyl chloride resin. Epoxidized vegetable oil is 5 to 15 parts by mass. Since epoxidized vegetable oil has a problem in cold resistance and compatibility, 7-12 mass parts is preferable. Moreover, in order to make hardness suitable for a wrap film, the total compounding quantity of a plasticizer is 20-45 mass parts with respect to 100 mass parts of vinyl chloride resin, Preferably it is 25-40 mass parts. When it is 40 parts by mass or less, the cut property is good and it is suitable for a small-sized household wrap film. Moreover, you may use a nontoxic plasticizer together with said plasticizer.
本発明で用いる成分（Ｂ）及び成分（Ｃ）は安定剤である。成分（Ｂ）は、オレイン酸のカルシウム塩とリシノール酸及び／又は安息香酸のカルシウム塩の混合物にオレイン酸及び／又はリシノール酸の亜鉛塩を加えた金属石鹸に、さらにエポキシ化大豆油又はエポキシ化アマニ油を加えて加熱して得た加熱溶解物である。これらの金属石鹸は酸性塩又は中性塩であってもよい。また上記の加熱温度は、５０〜１２０℃の温度範囲が好ましい。成分（Ｂ）は、塩化ビニル系樹脂１００質量部に対し、０．０５〜１．５質量部配合する。０．０５質量部未満では熱安定性効果が十分でなく、１．５質量部を超えるとブレートアウトや目ヤニが発生し易く、成形したフィルムの透明性も悪化しやすい。成分（Ｃ）は、トリデシルポリオキシエチレン（４〜１０）リン酸に、リン酸又は亜リン酸を加えて加熱して得た加熱溶解物である。成分（Ｃ）は、塩化ビニル系樹脂１００質量部に対し、０．００１〜１質量部配合する。０．００１質量部未満では透明性、熱安定性、着色防止性が十分でなく、１質量部を超えると目ヤニが発生し易くなり好ましくない。 Component (B) and component (C) used in the present invention are stabilizers. Component (B) is a metal soap obtained by adding oleic acid and / or zinc of ricinoleic acid to a mixture of calcium salt of oleic acid and calcium salt of ricinoleic acid and / or benzoic acid, and further epoxidized soybean oil or epoxidized It is a heated melt obtained by adding linseed oil and heating. These metal soaps may be acidic salts or neutral salts. The heating temperature is preferably in the temperature range of 50 to 120 ° C. Component (B) is blended in an amount of 0.05 to 1.5 parts by mass with respect to 100 parts by mass of the vinyl chloride resin. If the amount is less than 0.05 parts by mass, the thermal stability effect is not sufficient, and if it exceeds 1.5 parts by mass, blate-out and eye-cracking are likely to occur, and the transparency of the formed film tends to deteriorate. Component (C) is a heated melt obtained by adding phosphoric acid or phosphorous acid to tridecyl polyoxyethylene (4-10) phosphoric acid and heating. Component (C) is blended in an amount of 0.001 to 1 part by mass with respect to 100 parts by mass of the vinyl chloride resin. If it is less than 0.001 part by mass, the transparency, thermal stability and anti-coloring property are not sufficient, and if it exceeds 1 part by mass, it is not preferred because it tends to cause eye stains.
また、成分（Ｂ）、成分（Ｃ）と共に、成分（Ｅ）の合成ハイドロタルサイトを配合してもよい。合成ハイドロタルサイトは、一般式：Ｍｇ1-x・Ａｌx（ＯＨ）2・（ＣＯ3）x/2・ｍＨ2Ｏ （但し、式中、ｘは０．１＜ｘ≦０．３３の数を、ｍは０．１〜０．３の数をそれぞれ示す。）で表されるもの、例えば、Ｍｇ0.67Ａｌ0.33（ＯＨ）2（ＣＯ3）0.165・０．１Ｈ2Ｏ、Ｍｇ0.67Ａｌ0.33（ＯＨ）2（ＣＯ3）0.165・０．３Ｈ2Ｏ で表されるものが好ましい。その性状としては脱結晶水開始温度は約２３０℃、比表面積２０ｍ2／ｇ、粒度分布は１μｍ以下が９２％のものである。成分（Ｅ）は、塩化ビニル系樹脂１００質量部に対し、０．４〜１質量部配合する。０．４質量部未満では熱安定性、着色防止性が十分でなく、また１質量部を超えるとフィルムが白濁し透明性が悪化する。上記の安定剤のほかにカルシウムカルボン酸塩、亜鉛カルボン酸塩を併用してもよい。これらの成分（Ｂ）、成分（Ｃ）又は成分（Ｅ）を配合した安定化組成物は、昭島化学工業株式会社から市販されている。 Moreover, you may mix | blend the synthetic hydrotalcite of a component (E) with a component (B) and a component (C). The synthetic hydrotalcite has the general formula: Mg 1-x · Al x (OH) 2 · (CO 3 ) x / 2 · mH 2 O (wherein x is 0.1 <x ≦ 0.33 And m represents a number of 0.1 to 0.3, for example, Mg 0.67 Al 0.33 (OH) 2 (CO 3 ) 0.165 · 0.1H 2 O, Mg 0.67 Al What is represented by 0.33 (OH) 2 (CO 3 ) 0.165 · 0.3H 2 O is preferable. As its properties, the decrystallization water starting temperature is about 230 ° C., the specific surface area is 20 m 2 / g, and the particle size distribution is 92% with 1 μm or less. Component (E) is blended in an amount of 0.4 to 1 part by mass with respect to 100 parts by mass of the vinyl chloride resin. If the amount is less than 0.4 parts by mass, the thermal stability and anti-coloring property are not sufficient, and if it exceeds 1 part by mass, the film becomes cloudy and the transparency is deteriorated. In addition to the above stabilizer, calcium carboxylate and zinc carboxylate may be used in combination. A stabilizing composition containing these components (B), (C) or (E) is commercially available from Akishima Chemical Co., Ltd.
本発明では、可塑剤として、成分（Ａ）のグリセリン脂肪酸エステル及びエポキシ化植物油を用いる。上記の成分（Ｂ）、成分（Ｃ）又はこれらに成分（Ｅ）を配合した組成物は、環境ホルモン物質を含有しなく、塩化ビニル系樹脂の安定剤として優れたものであるが、可塑剤にグリセリン脂肪酸エステルを用いた場合には、加工時に着色し、ラップフィルムの商品価値が劣る。ところが、成分（Ｄ）のペンタエリスリトール又はジペンタエリスリトールと二塩基有機酸と炭素数８〜２４の脂肪酸との混合エステルを配合することによって、この加工時の着色を防ぐことができる。 In the present invention, the glycerin fatty acid ester of component (A) and epoxidized vegetable oil are used as the plasticizer. The above component (B), component (C) or a composition in which the component (E) is blended does not contain an environmental hormone substance, and is an excellent stabilizer for vinyl chloride resins. When glycerin fatty acid ester is used, it is colored during processing, and the commercial value of the wrap film is inferior. However, by blending a mixed ester of component (D) pentaerythritol or dipentaerythritol, a dibasic organic acid, and a fatty acid having 8 to 24 carbon atoms, coloring during this processing can be prevented.
成分（Ｄ）のペンタエリスリトール又はジペンタエリスリトールと二塩基有機酸と炭素数８〜２４の脂肪酸との混合エステルは滑剤である。融点が−５℃を超えるとブリードしてフィルムを白濁させるので、融点は−５℃以下が好ましく、更に好ましくは融点−１５℃以下である。この融点低下の観点から、ジペンタエリスリトールよりペンタエリスリトールが好ましい。前記の二塩基有機酸としては、マレイン酸、アジピン酸、セバシン酸、フタル酸などが挙げられる。また、炭素数８〜２４の脂肪酸としてはステアリン酸、オレイン酸、リノール酸、ラウリル酸などが挙げられるが、融点低下の観点から不飽和脂肪酸が好ましい。 Component (D) pentaerythritol or dipentaerythritol, a mixed ester of a dibasic organic acid and a fatty acid having 8 to 24 carbon atoms is a lubricant. When the melting point exceeds −5 ° C., the film bleeds and causes the film to become cloudy. Therefore, the melting point is preferably −5 ° C. or less, more preferably −15 ° C. or less. From the viewpoint of lowering the melting point, pentaerythritol is preferable to dipentaerythritol. Examples of the dibasic organic acid include maleic acid, adipic acid, sebacic acid, and phthalic acid. Examples of the fatty acid having 8 to 24 carbon atoms include stearic acid, oleic acid, linoleic acid, and lauric acid, and unsaturated fatty acids are preferable from the viewpoint of lowering the melting point.
成分（Ｄ）の配合量は、塩化ビニル系樹脂１００質量部に対し０．１〜１質量部の配合量でよい。但し、防曇剤などとしてオレイン酸化合物を配合した場合は、成分（Ｄ）のペンタエリスリトールと二塩基有機酸と炭素数８〜２４の脂肪酸との混合エステルとオレイン酸化合物との合計配合量を２質量％以下にする。この合計配合量が２質量％を超えるとフィルムが白濁し透明性が低下する。 The compounding amount of the component (D) may be 0.1 to 1 part by mass with respect to 100 parts by mass of the vinyl chloride resin. However, when an oleic acid compound is blended as an antifogging agent, etc., the total blending amount of the mixed ester of the component (D) pentaerythritol, a dibasic organic acid and a fatty acid having 8 to 24 carbon atoms and the oleic acid compound is 2% by mass or less. If this total amount exceeds 2% by mass, the film becomes cloudy and the transparency is lowered.
本発明の食品包装用塩化ビニル系樹脂ラップフィルムには防曇剤を配合するのが好ましい。防曇剤としてはモノグリセリン脂肪酸エステル、ジグリセリン脂肪酸エステル、ポリグリセリン脂肪酸エステル、ソルビタン脂肪酸エステル、蔗糖脂肪酸エステル、或はこれらのエチレンオキサイド付加物などが用いられる。具体的には、例えば、グリセリン・モノ・ベヘネート、グリセリン・モノ・ジヘネート、グリセリン・モノ・オレエート、グリセリン・モノ・ステアレート、グリセリン・モノ・ジリシノレート、ジグリセリン・モノ・オレエート、ジグリセリン・モノ・ラウレート、ポリグリセリンオレイン酸エステル、ポリグリセリンステアリン酸エステルなどである。防曇剤は１〜５重量％、好ましくは１〜２重量％配合する。配合量が１重量％未満では防曇効果が不十分であり、５重量％を越えると防曇剤が表面にブリードして自己粘着性が低下する。 It is preferable to add an antifogging agent to the vinyl chloride resin wrap film for food packaging of the present invention. As the antifogging agent, monoglycerin fatty acid ester, diglycerin fatty acid ester, polyglycerin fatty acid ester, sorbitan fatty acid ester, sucrose fatty acid ester, or these ethylene oxide adducts are used. Specifically, for example, glycerin mono-behenate, glycerin mono-dihenate, glycerin mono-oleate, glycerin mono-stearate, glycerin mono-dilysinolate, diglycerin mono-oleate, diglycerin mono-oleate Examples thereof include laurate, polyglycerol oleate, and polyglycerol stearate. The antifogging agent is added in an amount of 1 to 5% by weight, preferably 1 to 2% by weight. If the blending amount is less than 1% by weight, the antifogging effect is insufficient, and if it exceeds 5% by weight, the antifogging agent bleeds to the surface and the self-adhesiveness decreases.
またその他に必要に応じて樹脂フィルムには、着色防止剤、抗酸化剤、帯電防止剤、紫外線吸収剤、滑剤などが任意に配合される。滑剤としては、イソステアリン酸、ステアリン酸、パルミチン酸等の脂肪族酸系滑剤、ステアリン酸アマイド、メチレンビスステアロマイド等の脂肪酸アマイド系滑剤、ブチルステアレート等のエステル系滑剤、ポリエチレンワックス、流動パラフィン、高級アルコール等があげられる。 In addition, coloring agents, antioxidants, antistatic agents, ultraviolet absorbers, lubricants and the like are optionally blended in the resin film as necessary. Examples of the lubricant include aliphatic acid lubricants such as isostearic acid, stearic acid and palmitic acid, fatty acid amide lubricants such as stearic acid amide and methylene bisstearamide, ester lubricants such as butyl stearate, polyethylene wax, liquid paraffin And higher alcohols.
本発明の食品包装用塩化ビニル系樹脂ラップフィルムは、塩化ビニル系樹脂に前述の各配合物を配合し、常法により、押出成形機を用いてＴダイから押出し成形して製造できる。 The vinyl chloride resin wrap film for food packaging of the present invention can be produced by blending each of the aforementioned blends with a vinyl chloride resin and extruding from a T-die using an extruder in a conventional manner.
