Industry & Occupation
Classification
Summary
Manufacturing staff who mix raw materials for gel packs (cold packs) for low-temperature storage and perform filling, forming, and packaging operations using machines. Includes operating production lines, quality inspections, and machine maintenance checks.
Description
Cold pack manufacturing workers produce gel-like cold packs that exhibit cooling effects. They mix raw materials such as water, thickeners, and preservatives, stir them in dedicated mixing tanks, and then fill pouch containers using filling machines. After filling, they seal with sealers and, as needed, perform heating or cooling treatments to stabilize product characteristics. Finished products undergo quality inspections such as appearance checks and leak tests, then are packaged by packaging machines and prepared for shipment. Additionally, important tasks include regular machine inspections and cleaning, line troubleshooting, and workplace hygiene management. Shift work and standing operations are common, requiring compliance with hygiene and safety rules and teamwork.
Future Outlook
Stable demand is expected due to the expansion of cold chain needs for pharmaceuticals and food, but with advancing automation and labor-saving technologies, there is a trend toward requiring higher-level skills such as machine maintenance and quality control.
