Main Types Of Hydrogel Coating Machines

Categorized by functional application, hydrogel coating machines primarily include equipment for producing fever-reducing patches and cold compresses, medicated gel plasters, and facial masks. Machines designed for fever-reducing patches and cold compresses are used to manufacture cooling products; the typical structure of these products consists of a non-stick release layer, a gel reservoir layer containing the active ingredients, and a backing layer.

Categorized by technical characteristics, hydrogel coating machines can be classified into mold-pressing and rotary-cutting types, rotary-blade types, and small-scale laboratory models. The mold-pressing and rotary-cutting type employs a process in which coating and cutting are performed simultaneously, resulting in high production efficiency; examples of this category include the patented technology developed by Jianmin Group and Wenzhou Haofeng's MG-II600 model. The rotary-blade type utilizes rotary cutters for cross-cutting-often in conjunction with air knives for longitudinal slitting-thereby completing both the coating and slitting processes in a single pass.
