Description

종이를 이용한 식품 포장용기{A food packing instrument using paper}A food packing instrument using paper

본 발명은 종이를 이용한 식품 포장용기에 관한 것으로서, 더욱 상세하게는 기존 포장종이에 폴리아크릴레이트 공중합체를 3 ∼ 10 g/m2의 도포량으로 코팅하여 식품 포장용기를 제조함으로써, 인체에 무해하고 재활용이 가능하며 기존 코터(coater)기를 사용할 수 있어 경제적인 식품용 포장용기에 관한 것이다.The present invention relates to a food packaging container using paper, and more specifically, to a conventional packaging paper by coating a polyacrylate copolymer with a coating amount of 3 to 10 g / m 2 to produce a food packaging container, harmless to humans The present invention relates to an economical food packaging container that can be recycled and can use a conventional coater.

현재 사용되어 지고 있는 식품 포장용기는 크게 3가지로 구분되고 있으며, 첫째로 플라스틱, 스치로플을 주원료로 하는 제품과 둘째로 종이 표면에 폴리에틸렌(PE) 코팅 후 식품 포장용기로 사용한 제품 및 셋째로 천연 펄프 100%를 주원료로 하여 사용하는 제품이 있다. 그러나, 상기 첫 번째 제품은 재활용이 되지고 고가이며, 두 번째 제품은 재활용이 되지않아 제조과정 및 폐기과정에서 환경에 악영향을 끼치는 문제가 있고, 세 번째 제품은 원재료인 펄프를 수입에 의존하고 나무를 주원료로 하고 있기 때문에 경제적, 환경적으로 악영향을 끼치고 있으며, 일부 식품 포장용기는 코팅 처리되지 않은 재생펄프를 사용한 종이 제품을 사용하여인체에 유해한 증발 잔류물이 검출되어 사회적 물의를 빚고 있는 실정이다.Currently used food packaging containers are largely divided into three categories: firstly, plastics and styrople as main ingredients; secondly, polyethylene (PE) coating on paper surface, and thirdly, natural packaging. There is a product that uses 100% pulp as the main raw material. However, the first product is recycled and expensive, and the second product is not recycled, which adversely affects the environment during the manufacturing and disposal processes. The third product depends on imports of pulp, which is a raw material. It is economically and environmentally harmful because it is a main raw material, and some food packaging containers use paper products made of uncoated recycled pulp to detect harmful evaporation residues on the human body and cause social controversy. .

특히, 종이 표면에 폴리에틸렌(PE) 코팅 후 식품 포장용기로 사용한 제품은 기존종이 제조 공정 후 별도 가공기를 통하여 폴리에틸렌(PE)을 5 ∼ 20 g/㎡의 도포량으로 종이에 코팅하여 막을 형성시키는 것으로 제지 회사에서 이를 재활용시 펄프화(pulping)가 되지 않아 산업 폐기물화되는 문제가 있다.In particular, the product used as a food packaging container after coating the polyethylene (PE) on the surface of the paper paper to form a film by coating the polyethylene (PE) with a coating amount of 5 ~ 20 g / ㎡ through a separate processing machine after the existing paper manufacturing process When the company recycles it, there is a problem that industrial waste is not pulped.

이에, 본 발명자들은 상기한 문제점을 해결하기 위하여 기존 포장 종이에 폴리아크릴레이트 공중합체를 3 ∼ 10 g/m2의 도포량으로 코팅시켜 식품 포장용기를 제조함으로써 본 발명을 완성하였다.Thus, the present inventors completed the present invention by manufacturing a food packaging container by coating a polyacrylate copolymer in an application amount of 3 to 10 g / m 2 to the existing packaging paper to solve the above problems.

따라서, 본 발명은 인체에 무해하고 재활용이 가능하며 기존 코터(coater)기를 사용할 수 있어 경제적인 식품 포장용기를 제공하는데 그 목적이 있다.Therefore, the present invention is aimed at providing an economical food packaging container which is harmless to the human body, recyclable, and can use an existing coater.

본 발명은 종이를 이용한 식품 포장용기에서, 종이의 표면에 폴리아크릴레이트 공중합체를 3 ∼ 10 g/cm2의 도포량으로 코팅시킨 식품 포장용기를 그 특징으로 한다.The present invention is characterized by a food packaging container in which a polyacrylate copolymer is coated with a coating amount of 3 to 10 g / cm 2 on the surface of the paper in a food packaging container using paper.

이와같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.

본 발명은 기존 포장종이에 폴리아크릴레이트 공중합체를 일정량 코팅시켜식품 포장용기를 제조하여 종래 종이를 이용한 식품 포장용기가 재활용이 되지 않는 문제점을 해결하여 자원낭비 및 환경오염을 줄일 수 있으며, 또한 종이를 제조하는데 재생펄프를 사용함으로써 펄프 수입량을 줄여 경제적인 식품 포장용기에 관한 것이다.The present invention is to produce a food packaging container by coating a predetermined amount of the polyacrylate copolymer on the existing packaging paper to solve the problem that the food packaging container is not recycled using conventional paper can reduce the waste of resources and environmental pollution, and also paper The use of recycled pulp in the manufacture of pulp reduces the amount of pulp imports and is an economical food packaging container.

본 발명에서 특징적으로 사용하는 폴리아크릴레이트 공중합체는 내수성 및 내유성이 우수한 특징을 가지며, 소듐 라우릴 설페이트와 중아황산 나트륨 등을 공중합시켜 얻을 수 있다. 그리고, 본 발명에 따른 식품 포장용기는 기존의 포장종이의 표면에 상기한 폴리아크릴레이트 공중합체를 3 ∼ 10 g/cm2의 도포량으로 코팅시켜 식품 포장용기를 얻는다. 상기 코팅량이 3 g/cm2미만이면 내수성이 약하여 증발잔류물이 검출되어 식품 포장용기로 사용하기에 부적합하고, 10 g/cm2를 초과하면 품질은 이상이 없으나 원가가 향상되어 원가 경쟁력이 떨어진다.The polyacrylate copolymer characteristically used in the present invention has excellent water resistance and oil resistance, and can be obtained by copolymerizing sodium lauryl sulfate and sodium bisulfite. In addition, the food packaging container according to the present invention is coated on the surface of the existing packaging paper in a coating amount of 3 to 10 g / cm 2 of the above-mentioned polyacrylate copolymer to obtain a food packaging container. If the coating is less than the amount of 3 g / cm 2 when weak resistance to water is evaporated the residue is detected, suitable for use as food packaging containers, and exceeding 10 g / cm 2 quality, but at least the costs are improved less cost competitiveness .

이와같이, 상기한 폴리아크릴레이트 공중합체를 사용하여 제조한 본 발명에 따른 식품 포장용기는 내수성 및 내유성이 부여되어 인체에 유해한 증발잔류물이 검출되지 않는다. 또한, 종래의 폴리에틸렌을 사용하여 종이를 코팅하여 제조한 식품 포장용기는 폴리에틸렌이 열경화성 수지이므로 필름 형성후에는 분해되지 않아 물과 혼합상태에서 일정 압력과 회전력을 부여하는 제지일반 해리공정을 통해 펄프화 할 수 없어 재활용이 불가능한데 반해, 본 발명의 폴리아크릴레이트 공중합체는 열가소성 수지로 사용후 제지일반 해리공정에서 분해되어 펄프화 할 수 있어 재활용이 가능하다.As such, the food packaging container according to the present invention prepared using the above polyacrylate copolymer is endowed with water resistance and oil resistance so that no harmful evaporation residue is detected. In addition, food packaging containers prepared by coating paper using polyethylene in the prior art, because polyethylene is a thermosetting resin, do not decompose after film formation, and pulp through paper-based general dissociation process that imparts a constant pressure and rotational force in the mixed state with water. On the contrary, the polyacrylate copolymer of the present invention can be decomposed and pulped in the general paper dissociation process after use as a thermoplastic resin, and thus can be recycled.

본 발명에 따른 식품 포장용기의 제조공정을 간단히 살펴보면 다음과 같다.Looking briefly at the manufacturing process of the food packaging container according to the present invention.

먼저, 일반제지 공정에서와 같이 펄프를(천연,재생펄프 혼합) 이용하여 3 ∼ 8합으로 초지, 압착, 건조 공정을 거쳐 일반 비코팅지 상태로 제조한다. 그리고, 기존 코팅 설비를 이용하여 상기한 폴리아크릴레이트 공중합체를 종이 표면에 3 ∼ 10 g/㎡ 도포시켜 식품 포장용기를 제조한다. 상기 종이를 비코팅지 상태로 제조할 때 사용하는 펄프는 재생펄프와 천연펄프를 6 ∼ 10 : 0 ∼ 4 중량비로 혼합하여 사용하는 것이 경제적으로 유리하다.First, as in the general papermaking process, pulp (natural and recycled pulp mixture) is used to produce a general uncoated paper through papermaking, pressing, and drying in 3 to 8 combinations. Then, using the existing coating equipment is applied to the polyacrylate copolymer 3 to 10 g / ㎡ on the surface of the paper to prepare a food packaging container. The pulp used when the paper is produced in an uncoated paper state is economically advantageous to mix recycled pulp and natural pulp at a ratio of 6 to 10: 0 to 4 by weight.

이와같이, 본 발명에 따른 식품 포장용기는 기존 종이의 제조공정에 코팅공정을 삽입하여 포장용기의 제조공정이 간단하고 편리해졌다.As described above, the food packaging container according to the present invention is inserted into the coating process in the existing paper manufacturing process, the manufacturing process of the packaging container is simple and convenient.

이하, 본 발명을 실시예에 의거 상세히 설명하겠는 바, 본 발명이 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited by Examples.
