The Role of Release Films
Release films play a critical role in the sanitary napkin industry, primarily functioning to protect the integrity of sanitary napkins before use while enhancing the user experience. As consumer demands for higher-quality hygiene products increase, the design and performance of release films are continuously being improved.
Functions of Release Films
Release films are typically used at the bottom or as wrapping layers of sanitary napkins to shield the product from dust and contaminants in the external environment, ensuring its hygiene. Their unique release properties allow for easy peeling during use without damaging the adhesive layer.
Materials and Manufacturing of Release Films
Release films for sanitary napkins are commonly made of polymer materials such as PE cast films. These materials offer strong mechanical strength and effective moisture and dust resistance. Additionally, the surface of PE cast films is coated with a layer of silicone or other release agents to enhance release performance while ensuring that the adhesive layer’s stickiness remains unaffected.
Performance Requirements for Release Films
The sanitary napkin industry imposes high performance standards on release films, including:
Future Development Trends
In the future, release films will achieve more breakthroughs in functionality and eco-friendliness. For instance, adding antibacterial components to enhance hygiene performance or developing more environmentally friendly materials to meet the demand for green products from both consumers and the industry.
In summary, as a vital component of sanitary napkins, release films are constantly being optimized, providing essential support for industry development and improved user experiences.
