A transparent plastic container is mainly used as a packaging container for displaying contents such as products so as to be identifiable from the outside. Such transparent plastic containers are widely used for packaging of almost all products because of their advantages of being easy to mold, mass-produced, and inexpensive to manufacture. However, these plastic product packaging containers do not decompose semi-permanently during landfill treatment and remain in the ground, causing serious environmental pollution. In addition, when incinerated, harmful gases or environmental hormones are generated, and plastic product packaging containers are disposed of. There is a serious problem with a high load on the city's environment.

In order to respond to the global climate crisis, the international community has declared carbon neutrality and is actively promoting greenhouse gas reduction policies. In the packaging sector, reducing the amount of plastic used, which emits a lot of carbon during production and disposal, is becoming an essential task. In order to overcome the problem of high environmental load of plastic product packaging containers, methods of reducing plastic usage in the production stage and increasing products made of plastic that are easy to use and recyclable are being tried, but there is no realistic alternative other than using plastic. Plastic product packaging containers are still mainly used. Therefore, there is an urgent need for the development of product packaging containers using eco-friendly materials capable of lowering the environmental load.

The present applicant has devised a product packaging container made of paper that can meet these technical requirements, and a method of bonding the cut surfaces of the cut base paper to each other using an adhesive to create a three-dimensional shape that can accommodate the product. to be manufactured with However, in the case of manufacturing a paper product packaging container using an adhesive, there is a problem in that manufacturing cost increases because not only the increase in labor force according to the adhesive method, but also the need to have equipment for separate thermal bonding or high frequency bonding.
