Mosquito repellent patches can be efficiently manufactured using a hot melt adhesive coating machine, made by Trasy Enterprises. It is made by combining natural essential oils with pressure-sensitive adhesive (PSA) technology. The process begins with preparing a blend of natural oils such as Citronella, Eucalyptus, Lemongrass, and Rosemary. These oils are carefully mixed into a hot melt PSA under controlled temperature conditions to ensure uniform dispersion without degrading their active properties.
Once the adhesive mixture is ready, it is coated onto a silicone-coated release liner using a hot melt coating machine. The coating thickness is maintained precisely to ensure consistent performance and optimal release characteristics. After coating, the adhesive layer is laminated with a breathable non-woven fabric, which acts as the carrier material for the patch and ensures comfort when applied to the skin or clothing.
The laminated material is then passed through a cooling section to stabilize the adhesive layer. Following this, it is converted into patches by die-cutting into desired shapes and sizes, depending on product requirements.
The essential oils embedded within the adhesive provide a sustained release of fragrance over time. This continuous emission of natural aroma effectively repels mosquitoes, making the patches safe, convenient, and suitable for daily use.
