In accordance with this eco-friendly trend, replacing plastic or plastic foam containers with paper containers is becoming common in the market, preventing serious environmental problems. However, the biggest problem in using paper containers is insulation, which is often insulated when the user puts a high-temperature food into paper containers. This is often done by putting an insulating ring on the outside of the container Adiabatic effect was achieved. However, since the insulating ring is generally used in a large number of cases such as corrugated cardboard, the heat insulating performance is excellent. However, since the heat insulating ring must be additionally used when it is used, it is inconvenient for use, and the heat insulating ring slips easily, Drop. The foamed container is one layer of a heat insulating layer coated on the surface thereof.

Completion of this process consumes a large amount of resources. Therefore, there is a drawback that it is urgently necessary to supplement the burden of the foodservice and the consumer by increasing the selling price of the bubbling container by significantly increasing the manufacturing cost of the bubbling container.

Therefore, there is a need to provide a paper container with an unfoamed layer that is novel and novel to solve the above problem.

It is an object of the present invention to provide a paper container provided with an unfoamed layer, since the paper container having the unfoamed layer has a relatively low foaming temperature, it is not necessary to first carry out the heating foaming process at the time of manufacturing, When a food or liquid having a relatively high temperature is contained in a paper container having a foam layer, the unfoamed layer enters the foaming step itself after receiving heat, The present invention can drastically reduce the manufacturing cost and time compared to the well-known foam container.

In order to achieve the above object, the present invention provides a paper container having an unfoamed layer, wherein the paper container having the unfoamed layer includes a body and a heat insulating layer. The main body includes a base plate and a body portion, and the base plate and the body portion constitute an opening portion communicating with the accommodation space and the accommodation space, and the main body includes at least a paper layer. Wherein the insulating layer is at least partially screen printed on the outer surface of the body portion and comprises at least an unfoamed layer wherein the unfoamed layer comprises a water soluble acrylic resin portion, a foamed powder, a water soluble adjuvant portion and the water soluble acrylic resin portion and The water-soluble auxiliary agent portion integrally forms a substrate, the foam powder is uniformly distributed on the substrate, and the unfoamed layer has a foaming temperature.
