Description

Packaging box {PACKING BOX}

The present invention relates to a packaging box, and more particularly, to a packaging box having a heat insulation function.

In general, in order to store or transport contents such as food that require cooling, the contents are inserted into a packaging box or pack made of a material such as styrofoam or vinyl, and an ice pack is put together to be stored or transported.

However, the packaging box made of Styrofoam is currently widely used due to its excellent thermal insulation and cooling effect and light weight, but it is difficult to separate and collect and is the main culprit of environmental pollution.

Styrofoam easily breaks into small pieces, and these microscopic Styrofoam granules adsorb contaminants such as PCB, DDT, PAH, etc.

In addition, ice packs delivered together with the contents are easily thrown away by consumers as general waste, and these ice packs are also the main culprits of environmental pollution.

Ice packs contain moisture, so they do not burn well in incinerators, and when buried, it takes more than 500 years to completely decompose due to the plastic surrounding the refrigerant.

In addition, the ice pack contains a chemical called a gel-type super absorbent polymer, and is manufactured using microplastics to prevent it from bursting. If chemicals and microplastics, which are the contents of these ice packs, flow into rivers, it can cause water pollution.

Therefore, there is a need for an eco-friendly packaging box capable of achieving a cooling function by minimizing the use of ice packs without using Styrofoam as a packaging box.
