Hwajin is realizing the dream of customer satisfaction
with sophisticated and diverse packaging solutions.
For the past 20 years, Hwajin Co., Ltd. has been successfully supplying the highest quality drums to the semiconductors, displays, and secondary batteries industries.
Made of high-density polyethylene (HDPE), our product is safe for chemicals such as strong acids and alkalis. Our clean drums are produced under strict cleanliness control following a high-purity CLEAN process with a class 1,000 level.
The Ultra Clean Drum (UD-200L), which corresponds to the high and middle Grades, has a 3-layer structure and uses additive-free resin for the inner layer that is in direct contact with the storage material to minimize the increase in particles and metal.
