Structure for production of nano micro bubble and apparatus for production of nano micro bubble with that

摘要

PURPOSE: A laminated structure for producing nano micro bubbles is provided to reduce economical load by applying a microporous film of crystalline and non-crystalline regions through physical extension. CONSTITUTION: A laminated structure for producing nano micro bubbles comprises a microporous film and a microporous film back sheet supporter. The microporous film has microporosity from at least one kind of polyolefin-based resin through a dry extension method without organic solvent and solvent. The microporous film back sheet supporter is laminated in the rear side of the microporous film and passes the microporous film by dispersing the air.
