polymer coating of nonwoven fabric

[Anastasia191]

Hello! There are non-woven materials for medicine. They consist of a viscose-based absorbent material of 28 g/m2 and a polyethylene film of 25 g/m2. Does anyone know what kind of film this is? How is it applied to the material? I'm attaching a photo. The photo shows these two layers - the material and the film. It is very important to understand what kind of film it is. In order to understand how to cover non-woven fabric with such a film. After that, this material will be used in medicine. The material should absorb moisture on one side and repel on the other.

It must be heat bonded, since few adhesives work well on low surface energy materials like polyethylene.
