AI Technical Summary
Technical Problem
Existing feminine sanitary pads require an additional silicone coating treatment before use to provide peel properties, which increases processing steps and costs.
Method used
A polymer composition containing low-density polyethylene covalently bonded to polydimethylsiloxane is used as a release layer, which directly contacts the adhesive layer, avoiding the application and curing steps of silicone coating and providing good release properties.
Benefits of technology
This approach simplifies the processing steps, improves peeling properties, and reduces production complexity without increasing costs.
