Riqiang Five-Layer Co-extrusion Blown Film Machine

Product Description:

The Riqiang five-layer co-extrusion blown film machine features five independently controlled screw extrusion systems. Layers A, B, C, D, and E can be separately proportioned, temperature-controlled, and regulated, enabling multi-layer dissimilar material composite forming in a single pass — combining barrier layers, tie layers, strength layers, and heat-sealing layers. The machine is compatible with a wide range of materials including LDPE, HDPE, LLDPE, mLLDPE, EVA, PA nylon, EVOH high-barrier resin, and adhesive resins, producing both symmetrical and asymmetrical high-barrier functional films. Equipped with a five-layer planar stacking die head and IBC internal bubble cooling system, along with a 360° horizontal rotary haul-off unit, the machine delivers uniform film thickness and flat winding, with thickness deviation controlled within ±6%. Compared with traditional three-layer co-extrusion structures, the five-layer configuration enables further film thinning (15–25% thickness reduction) while significantly improving barrier performance and material utilization. The machine supports both air-cooled upward blowing and water-cooled downward blowing configurations, meeting packaging requirements across food, pharmaceutical, daily chemical, and industrial sectors.

English:

  • Five-layer independent control: Five sets of screws are fully independently driven, each layer capable of processing different materials for differentiated configuration of barrier, tie, strength, and heat-sealing layers
  • High-barrier structure: Supports combinations of PA, EVOH high-barrier resins with adhesive resins, significantly reducing oxygen transmission rate for food preservation, vacuum packaging, and retort applications
  • IBC internal bubble cooling: Ultrasonic bubble size control improves film transparency and output; combined with the five-layer planar stacking die head to ensure balanced and stable flow of all layers
  • 360° rotary haul-off: Horizontal rotary haul-off unit effectively improves winding flatness and reduces registration deviation in printing
  • Wide material compatibility: LDPE, HDPE, LLDPE, mLLDPE, EVA, PA, EVOH, PP, adhesive resins, and biodegradable materials
  • Thinning capability: Five-layer structure supports reduced-thickness production, achieving 15–25% thickness reduction compared with traditional structures and improving material utilization
  • High yield rate: Thickness deviation within ±6%, ensuring uniform and stable film output
