Problems solved by technology
In the known technology, the general release paper is a thin sheet. In order for the release paper to achieve the function of protecting the physiological patch and being easy to tear off, it is necessary to design and stack all the colloids on the patch in a planar form. Only paper can be effective; however, different colloids will have different specifications and application restrictions. The design may not be able to integrate and stack all the colloids into a plane, and poor stacking will cause gaps; if the release paper will not be able to truly protect the physiological Colloid on the patch will cause the colloid to be contaminated
In the known technology, there is also the use of thermoplastic film for hot pressing and spraying release agent to solve the problem of unevenness of the colloid of the physiological patch. Molding force, the stiff characteristic of the thermoplastic film also makes the design difficult and inconvenient to use

A three-dimensional elastic breathable physiological patch release film at least includes a release film layer, an elastic breathable layer and a bottom film layer; the release film layer has release performance and waterproof performance, can be bonded on glue of a physiological patch and can be easily demounted; the elastic breathable layer can match the physiological patch structure, provide stacking supporting demands of different height drops, has breathable performance, and can balance air pressure in different spaces; the bottom film layer matches a physiological patch appearance, and provide a base to combine all the materials together through a back glue layer. The three-dimensional elastic breathable physiological patch release film can solve the problem of height drops of the glue of the physiological patch, can provide supporting and air pressure balancing functions, can lower the manufacturing difficulty and the high cost, and can protect and support the physiological patch while reducing the cost.
Description
technical field [0001] The invention is a release film, especially a kind of elastic breathable layer to provide space stacking and support functions, which can match the height difference of the physiological patch colloid, and can balance the air pressure in different spaces through its breathable function Three-dimensional elastic breathable physiological patch release film. Background technique [0002] Physiological patches need to use biocompatible adhesives to stick the patch on the body, and use various colloids with different materials and characteristics to achieve the functions required by the patch. For example: conductive glue can conduct physiological electrical signals, Anti-scar glue can prevent and improve the formation of scars on the skin, artificial skin can absorb tissue fluid and help wound recovery, breathable glue can increase the comfort of attachment, etc.; various glues will have different specifications and application restrictions, and physiologi...
