In case of cup ramen container, proper heat insulation is required because hot water is used to cook ramen. Accordingly, the cup noodle containers are manufactured using the expandable polystyrene container having excellent heat insulating properties. However, in the case of effervescent polystyrene, the printability is low, and only the lid made of paper is sold with the brand or the like printed thereon.

In contrast, paper cups can be printed, but the thermal insulation is very low, making it difficult to hold the cups with hot water or coffee. In addition, the recent coffee specialty coffee has a large capacity, it is not easy to use in a paper cup. Accordingly, the cylindrical paper that can be inserted into the cup can be dispensed.
이에 따라, 단열 특성이 우수하면서도 인쇄적성이 좋은 새로운 컵에 대한 요구가 계속되고 있다. Accordingly, there is a continuing need for new cups having excellent thermal insulation properties and good printability.
본 발명에서 해결하고자 하는 과제는 단열 특성이 우수하면서, 인쇄적성이 좋은 새로운 용기를 제공하는 것이다.The problem to be solved in the present invention is to provide a new container having excellent thermal insulation properties, good printability.
