Description
本發明是關於用於製造容器包裝食品之填充食品用紙容器，該容器包裝食品是將豆腐等的食品材料填充於容器後，將其密封、加熱固化而成。 The present invention relates to a filled food paper container for producing a container-packed food, which is obtained by filling a food material such as tofu with a container, sealing it, and heating and solidifying it.
將豆腐、水羊羹、布丁等的材料填充於容器，將其密封、加熱固化而製造的食品(以下稱為填充食品)是已知的。 A food (hereinafter referred to as a filled food) produced by filling a container with a material such as tofu, water alpaca, and pudding, and sealing and heating and solidifying it is known.
例如，在填充食品為豆腐的情況，是在容器內填充包含豆漿、凝固劑之豆腐材料後將其密封，將填充有豆腐材料之容器於60~100度進行加熱，藉此製造填充豆腐(例如，參照專利文獻1)。 For example, in the case where the filled food is tofu, the container is filled with the tofu material containing the soybean milk and the coagulant, and then sealed, and the container filled with the tofu material is heated at 60 to 100 degrees to produce filled tofu (for example, Refer to Patent Document 1).
作為在包括填充豆腐之填充食品所使用的容器，金屬容器、合成樹脂容器、紙容器等是已知的，基於使用後的容易廢棄、回收特性等觀點，紙容器正在普及。作為將食品密封收容的紙容器，由下述紙容器材料所形成的紙容器是已知的(例如，參照專利文獻2)，該紙容器材料，從外面側朝向內面側係具備：以聚乙烯樹脂為主成 分之熱可塑性樹脂層、紙基材層、以聚乙烯樹脂為主成分之熱可塑性樹脂層、阻隔層、以及最內層之以聚乙烯樹脂為主成分的熱可塑性樹脂層。 Metal containers, synthetic resin containers, paper containers, and the like are known as containers for use in filled foods filled with tofu, and paper containers are popularized from the viewpoints of easy disposal after use, collection characteristics, and the like. A paper container formed by sealing a food container is known as a paper container formed of the following paper container material (for example, see Patent Document 2), and the paper container material is provided from the outer surface side toward the inner surface side: Vinyl resin The thermoplastic resin layer, the paper base material layer, the thermoplastic resin layer mainly composed of a polyethylene resin, the barrier layer, and the thermoplastic resin layer containing the polyethylene resin as a main component in the innermost layer.
然而，當使用由專利文獻2記載的紙容器材料所形成之紙容器作為填充食品容器的情況，在容器內固化後的食品和構成容器的內面之以聚乙烯樹脂為主成分之熱可塑性樹脂層之分離性不佳，在取出時食品可能附著於內面而難以取出，或一部分發生破損。 However, when the paper container formed of the paper container material described in Patent Document 2 is used as the filled food container, the food after curing in the container and the thermoplastic resin containing the polyethylene resin as the main component constituting the inner surface of the container are used. The separation property of the layer is not good, and the food may adhere to the inner surface when taken out, and it is difficult to take out, or a part of the food may be damaged.
為了改善容器內面和在容器內固化後之食品的分離性，在聚烯烴系樹脂添加選自多元醇或其衍生物及聚氧乙烯衍生物之調配劑而成之聚烯烴系樹脂組成物已被提出(例如，參照專利文獻3)。 In order to improve the separation property of the inner surface of the container and the food after curing in the container, a polyolefin resin composition obtained by adding a preparation agent selected from the group consisting of a polyhydric alcohol or a derivative thereof and a polyoxyethylene derivative to the polyolefin resin has been used. It is proposed (for example, refer to Patent Document 3).
如果將該專利文獻3所記載的技術運用於專利文獻2所記載的紙容器材料之最內層，可改善紙容器的內面和食品之分離性，而能從紙容器將食品輕易地取出。 When the technique described in Patent Document 3 is applied to the innermost layer of the paper container material described in Patent Document 2, the inner surface of the paper container and the separation property of the food can be improved, and the food can be easily taken out from the paper container.
作為將專利文獻3所記載的技術運用於專利文獻2所記載的紙容器材料的最內層之一例可考慮：在構成上述紙容器材料的最內層之以聚乙烯樹脂為主成分的熱可塑性樹脂層上，積層聚乙烯樹脂薄膜來構成最內層；該聚乙烯樹脂薄膜，係添加有選自多元醇或其衍生物及聚氧乙烯衍生物之調配劑。 As an example of applying the technique described in Patent Document 3 to the innermost layer of the paper container material described in Patent Document 2, it is conceivable that thermoplasticity containing a polyethylene resin as a main component in the innermost layer constituting the paper container material is considered. On the resin layer, a polyethylene resin film is laminated to form an innermost layer; and the polyethylene resin film is added with a preparation selected from a polyhydric alcohol or a derivative thereof and a polyoxyethylene derivative.
然而，若使用由如此般獲得之紙容器材料所形成的紙容器作為填充食品容器，在添加有調配劑之構成最內層的聚乙烯樹脂層、和位於其內側之以聚乙烯樹脂為主成分的 熱可塑性樹脂層之間，可能發生剝離而造成內容液漏出。 However, if a paper container formed of the paper container material thus obtained is used as the filled food container, the polyethylene resin layer constituting the innermost layer to which the compounding agent is added, and the polyethylene resin as the main component on the inner side thereof are used. of Between the thermoplastic resin layers, peeling may occur to cause leakage of the content liquid.

添加有上述調配劑之構成最內層的聚乙烯樹脂層、和位於其內側之以聚乙烯樹脂為主成分之熱可塑性樹脂層之間所發生的剝離，其原因在於：當將食品材料填充於容器，將其密封加熱時，添加於最內層的聚乙烯樹脂層之調配劑會溶出，而轉移到其和位於內側之以聚乙烯樹脂為主成分的熱可塑性樹脂層之間。 The peeling occurred between the polyethylene resin layer constituting the innermost layer of the above-mentioned compounding agent and the thermoplastic resin layer containing the polyethylene resin as the main component inside thereof is added because the food material is filled in When the container is sealed and heated, the preparation agent added to the innermost layer of the polyethylene resin layer is eluted and transferred between the thermoplastic resin layer containing the polyethylene resin as the main component on the inner side.
本發明人等，為了防止從添加有調配劑之構成最內層的聚乙烯樹脂層溶出之調配劑轉移到位於其內側之以聚乙烯樹脂為主成分的熱可塑性樹脂層之間，針對填充食品用的紙容器反覆進行試驗研究的結果發現，在添加有調配劑之聚乙烯樹脂層和位於其內側之以聚乙烯樹脂為主成分的熱可塑性樹脂層之間，介入由聚乙烯樹脂和聚丙烯樹脂所混合成之熱可塑性樹脂層，藉此可防止從添加有調配劑之聚乙烯樹脂層溶出的調配劑轉移到位於內側之以聚乙烯樹脂為主成分的熱可塑性樹脂層之間，而到達本發明的完成。 The present inventors have prevented the transfer of the preparation agent eluted from the polyethylene resin layer constituting the innermost layer to which the preparation agent is added, to the thermoplastic resin layer containing the polyethylene resin as the main component on the inner side, for the filled food. As a result of repeated experimental research on the paper container, it was found that the polyethylene resin and the polypropylene were interposed between the polyethylene resin layer to which the compounding agent was added and the thermoplastic resin layer containing the polyethylene resin as the main component inside. The thermoplastic resin layer in which the resin is mixed, thereby preventing the transfer agent which is eluted from the polyethylene resin layer to which the compounding agent is added from being transferred to the thermoplastic resin layer containing the polyethylene resin as the main component inside, and reaching The completion of the present invention.

(B layer), thermoplastic resin layer (C layer) with main component of polyethylene resin, barrier layer (D layer), ethylene. A methacrylate copolymer resin as an adhesive layer (E layer) as a main component, a thermoplastic resin layer (F layer) mainly composed of a polyethylene resin, and a thermoplastic resin obtained by mixing a polyethylene resin and a polypropylene resin Layer (G layer), added to polyethylene resin (polyolefin resin) A thermoplastic resin layer (H layer) selected from the group consisting of a polyol or a derivative thereof and a polyoxyethylene derivative.
上述積層構造當中之以聚乙烯樹脂為主成分之熱可塑性樹脂層(A層)、紙基材層(B層)、以聚乙烯樹脂為主成分之熱可塑性樹脂層(C層)、阻隔層(D層)、以乙烯．甲基丙烯酸酯共聚物樹脂為主成分之黏著層(E層)、以聚乙烯樹脂為主成分之熱可塑性樹脂層(F層)的積層構造，係與作為習知的液體紙容器所使用之容器材料相同。 Among the laminated structures, a thermoplastic resin layer (A layer) mainly composed of a polyethylene resin, a paper substrate layer (B layer), a thermoplastic resin layer (C layer) mainly composed of a polyethylene resin, and a barrier layer (D layer), with ethylene. A laminated structure of an adhesive layer (E layer) containing a methacrylate copolymer resin as a main component and a thermoplastic resin layer (F layer) containing a polyethylene resin as a main component, and a liquid paper container used as a conventional one. The container material is the same.
在本例，熱可塑性樹脂層(C層)的成分為直鏈狀低密度聚乙烯樹脂(LLDPE)，熱可塑性樹脂層(F層)的成分為高壓法低密度聚乙烯樹脂(LDPE)。此外，阻隔層(D層)是使用鋁箔。 In this example, the component of the thermoplastic resin layer (C layer) is a linear low-density polyethylene resin (LLDPE), and the component of the thermoplastic resin layer (F layer) is a high-pressure method low-density polyethylene resin (LDPE). Further, the barrier layer (D layer) is an aluminum foil.
形成本發明的填充食品用紙容器之容器材料，是在如上述般進行積層之積層構造之熱可塑性樹脂層(F層)的外側(容器內面側)，積層熱可塑性樹脂層(G層)、熱可塑性樹脂層(H層)。 The container material of the paper container for filling foods of the present invention is the outer side (the inner surface side of the container) of the thermoplastic resin layer (F layer) having a laminated structure as described above, and the thermoplastic resin layer (G layer) is laminated. Thermoplastic resin layer (H layer).
積層於熱可塑性樹脂層(F層)的外側之熱可塑性樹脂層(G層)的成分，是使用由聚乙烯樹脂和聚丙烯樹脂所混合成之熱可塑性樹脂。 The component of the thermoplastic resin layer (G layer) laminated on the outer side of the thermoplastic resin layer (F layer) is a thermoplastic resin obtained by mixing a polyethylene resin and a polypropylene resin.
聚乙烯樹脂：聚丙烯樹脂的混合比較佳為3：7~4：6。若聚乙烯樹脂的比例為4以上，從後述的熱可塑性樹脂層(H層)溶出之調配劑的抑制效果降低，若聚乙烯樹脂的比例為3以下，黏著性會降低。 Polyethylene resin: The mixing of polypropylene resin is preferably 3:7~4:6. When the ratio of the polyethylene resin is 4 or more, the inhibitory effect of the preparation which is eluted from the thermoplastic resin layer (H layer) to be described later is lowered, and when the ratio of the polyethylene resin is 3 or less, the adhesiveness is lowered.
此外，熱可塑性樹脂層(H層)係構成最內層(容器內面)，在本例，其成分為直鏈狀低密度聚乙烯樹脂(LLDPE)，是在聚乙烯樹脂(聚烯烴系樹脂)添加有選自多元醇或其衍生物及聚氧乙烯衍生物之調配劑。調配劑的添加量為5~20%，較佳為10%。若調配劑的添加量未達5%，紙容器的內面、亦即熱可塑性樹脂層(H層)和食品的分離性變差，若超過20%，熱可塑性樹脂層(H層)的黏著性降低。 Further, the thermoplastic resin layer (H layer) constitutes the innermost layer (inner surface of the container), and in this example, the component is a linear low-density polyethylene resin (LLDPE), and is a polyethylene resin (polyolefin resin). A compounding agent selected from the group consisting of a polyhydric alcohol or a derivative thereof and a polyoxyethylene derivative is added. The amount of the compounding agent added is 5 to 20%, preferably 10%.

Since the thermoplastic resin layer (H layer) is a mixture of a polyol or a derivative thereof and a polyoxyethylene derivative, the inner surface of the paper container and the food are excellent in separation property, and the food can be easily taken out from the paper container.
此外，在熱可塑性樹脂層(H層)和其內側之以聚乙烯樹脂為主成分之熱可塑性樹脂層(F層)之間介入由聚乙烯樹脂和聚丙烯樹脂所混合成之熱可塑性樹脂層(G層)而成為積層構造，因此在將豆腐等的食品材料填充於容器後將其密封、加熱固化的製造過程，來自最內層之熱可塑性樹脂層(H層)之調配劑的溶出可藉由熱可塑性樹脂層(G層)予以抑制，能防止其往熱可塑性樹脂層(F層)轉移，可防止前述熱可塑性樹脂層(H層)從熱可塑性樹脂層(F層)的剝離發生。 Further, a thermoplastic resin layer obtained by mixing a polyethylene resin and a polypropylene resin is interposed between a thermoplastic resin layer (H layer) and a thermoplastic resin layer (F layer) mainly composed of a polyethylene resin inside thereof. (G layer) is a laminated structure. Therefore, in a manufacturing process in which a food material such as tofu is filled in a container, and then sealed and heated and solidified, the preparation of the formulation from the thermoplastic resin layer (H layer) of the innermost layer can be performed. By suppressing the thermoplastic resin layer (G layer), it is prevented from being transferred to the thermoplastic resin layer (F layer), and peeling of the thermoplastic resin layer (H layer) from the thermoplastic resin layer (F layer) can be prevented. .
