Aseptic Filling

The Aseptic Filling System that Samyang Packaging introduced for the first time in the domestic market is an advanced beverage filling system that operates the entire process of beverage production in a bacteria-free environment.

Aseptic Filling avoids long time pasteurization of beverages in a high temperature in order to minimize the destruction of nutrients. The system instantly cools beverage after flash pasteurization to retain the unique flavor of beverages.

For the first time in Korea, Samyang Packaging constructed an aseptic plant that can produce as much as 450 million bottles per year in Gwanghyewon. The factory provides a one-stop production system which produces preform, molding, mixing beverages, filling beverages, and packaging with its advanced facilities and technology. In addition, the company also created a brand name for the aseptic filling system, Asepsys, and included the label on all products to help consumers to easily recognize clean and hygienic aseptic filling beverages.
