[0002] Transdermal patches are a route of administration that allows drugs to be absorbed through the skin to produce systemic or local therapeutic effects. Usually, transdermal patches are composed of a protective film, a drug-containing adhesive layer, and a backing layer. A film-making machine is used to coat the drug-containing adhesive material on the backing layer, and then a protective film is compounded, and then a packaging machine is used to package it. Usually, in order to facilitate the tearing of the drug film, a tear line will be set on the protective film, and then the transdermal patch is packaged into bags using packaging materials.

[0003] The utility model document with patent number CN219382903U discloses a patch forming and packaging machine, including a patch extruder. After the patch is extruded, it falls onto the extrusion conveyor belt and is sent to the rolling mouth of the patch roller to be evenly extruded. The upper and lower trimming pieces of the patch cut off the uneven parts on both sides of the patch, and then the pearlescent film, non-woven release paper, and adhesive non-woven fabric are laid on the bottom of the patch, and then the patch is roll-cut by the patch roller cutting group. After rolling, the packaging film is covered on the pearlescent film, non-woven release paper and adhesive non-woven fabric bottom, and then the second release paper, the first release paper and the top of the patch are covered. After covering, the upper packaging is carried out, the packaged patch is heat-sealed, and then the scrap corners of the sealed plaster package are cut, and after cutting, they are introduced into the product roller cutting piece for cutting, and the product is obtained after cutting.
