The Application of Release Films for the Sanitary Napkins

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:

1. Hygiene: Compliance with national and industry hygiene standards, ensuring safety with non-toxic and harmless materials.
2. Stability: Maintaining consistent release performance under varying temperature and humidity conditions, avoiding issues like over-stickiness or excessive slipperiness.
3. Eco-friendliness: As environmental awareness grows, biodegradable or recyclable release films are becoming a development trend.
4. Convenience: Allowing users to use quickly and easily.

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.
