Description

폴리에틸렌 또는 폴리프로필렌/폴리스티렌페이퍼/고강도폴리스티렌 적층구조의 시트, 이의 제조방법, 및 이를 이용한 라면용기Polyethylene or polypropylene / polystyrene paper / high strength polystyrene laminated structure sheet, method for preparing the same, and ramen container using the same

본 발명은 가혹한 조건하에서도 내분비계 교란 의심물질이 용출되지 않는 폴리에틸렌(PE; PolyEthylene) 또는 폴리프로필렌(PP; PolyPropylene)/폴리스티렌페이퍼(PSP; PolyStyrene Paper)/고강도폴리스티렌(HIPS; High Impact PolyStyrene) 적층구조의 라면용기용 시트, 이의 제조방법 및 이를 사용하여 얻어지는 라면용기에 관한 것이다.The present invention is a polyethylene (PE; PolyEthylene) or polypropylene (PP; PolyPropylene) / polystyrene paper (PSP; PolyStyrene Paper) / HIPS (High Impact PolyStyrene) lamination that does not elute suspicious endocrine disruptive substances even under severe conditions The present invention relates to a ramen container sheet having a structure, a manufacturing method thereof, and a ramen container obtained by using the same.

현재 국내외적으로 라면용기는 PSP, EPS(Expanded PolyStyrene)나 PP, 종이재질 등을 사용하여 각각 다른 성형 방법으로 제조되어 사용되고 있다. 가장 많이 사용되는 PSP의 경우 압출진공성형법이, 종이의 경우 접합성형법이 사용된다.Currently, ramen containers at home and abroad are manufactured and used in different molding methods using PSP, EPS (Expanded PolyStyrene) or PP, and paper materials. For the most commonly used PSP, extrusion molding is used, and for paper, bonding is used.

라면 용기의 경우, 더운물을 넣고 조리하게 되므로, 무엇보다 단열성이 우선 되어야 하는 데, PSP, EPS 용기와는 달리, PP나 종이 용기는 단열성이 부족하여 PP의 경우, 용기의 외벽 두께를 두껍게 하거나, 이중으로 제조하여야 하며, 종이의 경우, 콜게이트나 엠보싱 방식으로 외벽에 한겹을 더 접합하는 방식으로 제조하여야 하므로, 단열성과 경제성에서 문제가 되어 왔다.In the case of ramen containers, hot water is cooked, so heat insulation must be prioritized. Unlike PSP and EPS containers, PP or paper containers lack heat insulation, so in the case of PP, the outer wall thickness of the container is increased, It should be manufactured in duplicate, and in case of paper, it has to be manufactured in a manner of further bonding one layer to the outer wall by a colgate or embossing method, which has been a problem in heat insulation and economy.

PSP 용기는 우수한 단열성과 더불어 경제성을 나타내어 수년간 라면용기로 사용되어 왔으나, 최근 PSP 용기에서 비록 위해성이 없는 것으로 판명되기는 하였으나, 가혹한 조건하(30분 이상 조리 또는 전자레인지 조리)에서 미량으로 용출(ppb 단위)되는 스티렌 다이머, 스티렌 트리머 등이 내분비계 교란 의심물질로 논란이 되고 있다.PSP containers have been used as ramen containers for many years because of their excellent thermal insulation and economic performance, but they have recently been found to be non-hazardous in PSP containers. Styrene dimers, styrene trimers, and the like have been controversial as suspected endocrine disruptors.

본 발명은 종래 기술에 의한 라면용기가 가지는 상기와 같은 문제점을 해결하여, 가혹한 조건에서도 내분비계 교란 의심물질이 용출되지 않는 라면용기용 시트 및 이를 사용하여 제조되는 라면용기를 제공하는 데에 목적이 있다.The present invention is to solve the problems as described above having a conventional ramen container, to provide a ramen container sheet and a ramen container manufactured using the same, the endocrine disrupting susceptible substance is not eluted even under severe conditions. have.
