For the past 70 years, the only material with insulation properties for foamed food containers has been PS (polystyrene). However, as the use of polystyrene is increasingly banned in various countries worldwide due to its inability to be heated in a microwave and the risk of styrene monomer leaching, which is considered carcinogenic, there has been an urgent need for the development of alternatives in this field.

PP (polypropylene) is a resin that has been proven safe for food containers, but it has low melt strength and belongs to the category of crystalline polymers, making the window for foaming extrusion processes very narrow, which previously made the development of foaming technology impossible.

Our company has resolved the technical challenges mentioned above and has successfully completed a high-bulk physical foaming technology using only gas during the foaming process without any chemical additives, realizing the 'non-crosslinked continuous extrusion foaming technology.'

Through this, we have introduced an eco-friendly and innovative food container that compensates for the shortcomings of the aforementioned materials, achieving a fundamental reduction in plastic usage through the foaming process.

The key features of this container can be summarized as follows:

1. Microwave heat resistance suitable for frozen convenience foods, insulation that does not get hot, and human safety that differentiates it from polystyrene.


2. A weight reduction effect of 20-50% compared to non-foamed PP, enabling a fundamental reduction in plastic usage.


3. Approximately 24% reduction in greenhouse gases compared to non-foamed PP, contributing to carbon neutrality.


4. Capable of being manufactured in the form of high-insulation cold and hot beverage cups, reducing waste from paper cups and cup holders.


5. As a non-crosslinked foamed material, it retains the excellent recyclability of PP.
