Abstract
Description
본 발명은 내수성 및 내유성을 가지는 친환경 코팅제를 사용한 강화 페이퍼몰드에 관한 것이다.The present invention relates to a reinforced paper mold using an eco-friendly coating agent having water resistance and oil resistance.
편리한 생활용품에 큰 가치를 부여하는 현대사회에서 플라스틱의 의존성은 대단히 높으며, 플라스틱은 특유의 가볍고 강한 물성 때문에 여전히 다양한 분야에서 선호되는 산업재료로 선택되고 있다. 대량생산과 대량소비의 편리성과 경제성 덕분에, 환경적 염려에도 불구하고 석유유래 플라스틱의 사용량은 증가하고 있으며 일회용 식품용기 시장에도 적극적으로 적용되고 있다.In modern society, which places great value on convenient household items, the dependence on plastic is very high, and plastic is still selected as a preferred industrial material in various fields because of its unique light and strong physical properties. Thanks to the convenience and economy of mass production and mass consumption, despite environmental concerns, the use of petroleum-derived plastics is increasing and is actively applied to the disposable food container market.
이들 합성수지류의 생활폐기물들은 소각 시에는 다량의 유독가스성분을 방출하여 대기오염을 유발하고, 매립 시에는 수백 년 간 분해되지 않은 채 토양과 해양오염을 유발하고 있어 이 같은 재앙을 조금이라도 피해보고자, 이전부터 각종 방법의 친환경적 대체재료들의 개발이 있어 왔다.When these synthetic resin wastes are incinerated, they release a large amount of toxic gases, causing air pollution. When buried, they do not decompose for hundreds of years and cause soil and marine pollution. , there have been developments of eco-friendly alternative materials in various ways from before.
수분과 유분을 함유한 식품이나 음료분야에서는 기본적으로 내수성과 내유성의 기능을 갖는 포장재를 사용한다. 종이류는 이러한 물성이 부족하여, 열가소성 합성수지인 폴리에틸렌(PE)를 코팅하거나 라미네이팅 하는 방법으로 기본물성을 보강하여 널리 사용하고 있다. 더욱이 열봉합성이 좋아서, 종이컵이나 종이용기에서 경쟁대안 없이 압도적으로 사용되고 있다.In the field of food or beverage containing water and oil, packaging materials having water resistance and oil resistance are basically used. Paper lacks these physical properties, so it is widely used by reinforcing basic physical properties by coating or laminating polyethylene (PE), a thermoplastic synthetic resin. Moreover, because of its good heat-sealability, it is overwhelmingly used in paper cups and paper containers without competing alternatives.
문제는, 이 폴리에틸렌이 친환경적이지 않다는 점이다. 사용 후, 제지원료로 재활용되기는 하지만 폴리에틸렌의 제거과정에서 종이의 펄프섬유가 손상되어, 제한된 수준에서만 재활용이 된다. 순수폐지가 아니므로 선별 및 분류에 따른 비용의 발생도 적지 않다.The problem is that this polyethylene is not environmentally friendly. After use, it is recycled as a paper raw material, but in the process of removing polyethylene, the pulp fibers of the paper are damaged, so it is recycled only at a limited level. Since it is not a pure abolition, the cost of sorting and sorting is not insignificant.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 내수성 및 내유성이 우수한 내수내유제를 포함하는 페이퍼몰드를 제공하는 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a paper mold containing a water-resistant and oil-resistant agent having excellent water resistance and oil resistance.
