Trans-Dermal Patch Making Machines

A transdermal patch making machine line typically consists of a hot melt adhesive coating machine followed by a slitting cum cutting machine, enabling continuous and efficient production of medicated or herbal patches. The hot melt coating machine precisely applies molten adhesive onto the release liner or backing film, ensuring uniform coating thickness and consistent adhesive performance. After coating and lamination, the web is accurately slit and cut into finished patch sizes by the slitting cum cutting machine, maintaining high dimensional accuracy and productivity.

The use of hot melt adhesive in transdermal patches offers several key advantages. Hot melt systems are solvent-free, eliminating drying time, solvent recovery, and residual solvent risks. They provide excellent skin adhesion, flexibility, and comfort during wear, which is critical for long-duration patches. Hot melt adhesives also allow controlled drug or herbal ingredient release, improving patch efficacy. The process is energy-efficient, environmentally friendly, and suitable for heat-stable actives. Additionally, hot melt technology enables high-speed continuous manufacturing, better batch-to-batch consistency, reduced material wastage, and easier scale-up for commercial production.
