Description
Multilayer АВC / ABCDE - multilayer blown film lines
manufactured by the company "Aleko", Russia
Processed materials:- LDPE, HDPE, LLDPE, mLDPE, PA, EVA, EVOH, и т.д.
- lamination film
- barrier film
- film for freezing
- milk film
- Shrink film
- Courrier bag film
- All series of Aleko blown film machines are fitted with high-performance screws which are manufactured under license of Plamex Company, (Germany)
- The screws have a complex geometric shape, which makes it possible to achieve high performance and efficient blending
- Our screw work well on recycled materials and cases when good level of homogenization of hard mixing polymers is required.
Liners:
-
Screw cylinders are technically designed with an integrated feed section
Feed section with helical grooves (flutes)
Heating: ceramic and mica heaters
Cooling: axial-flow fans
-
Horizontal rotating device: width 1500-2100 mm
Vertical rotating device: width 800-1300 mm
- Thickness tolerance up to ±1,5%
-
Compression type with two barrier zones and one mixing zone
Made of steel with bimetallic coating
Diameters: 45/55/65/65/75/90 at customer's option
- Gearboxes of all Aleko series are designed for high loads.
- Bearings and gear wheels are lubricated by immersing in oil. Oil cooling is made via heat exchange unit
- Main bearing is integrated in gear case, which provides constant lubrication
- Possibility to be equipped with single station winder or double station back-to-back type winder. All winders are contact type with tension control system, EPC system can be installed optionally
- Optimal polymer rheology
- Short channels for material flow
- Temperature maintenance
- Effective system of air inlet for IBC
- Working surface with hard chrome plating (thickness 30 mcm)
- Thermal insulation of each layer
- Possibility of changing the number of layers (up to 9 layers)
