Five Layer Co-extrusion Film Blowing Machine

Applications
The five layer co-extrusion film blowing machine is mainly applied in producing film out of resin materials with gas barrier property, such as HDPE, MHDPE, LDPE, LLDPE, MLLDPE, PA, and EVOH, etc. The film made by our five layer co-extrusion film blowing machine is used as packaging materials for heavy duty bags, top-grade food bags, vacuum packaging bags and liquid packaging bags, achieving air tight, antiseptic, shelf life extending, aroma and fresh keeping packaging.

Features
1. Our five layer co-extrusion film blowing machine makes use of multilayer co-extrusion stacked die head, IBC (inner bubble cooling) system, rotating traction, automatic winding and other advanced techniques.
2. The film made by our machine has superior barrier performance and high heat sealability.
3. The co-extrusion film blowing machine boasts compact structure, reliable performance and high productivity.
